The combustion chamber is where combustion takes place in a jet engine. There are three main types of combustors: can, cannular, and annular. The can combustor has individual combustion cans each with their own fuel injector, igniter, and casing. The cannular combustor is similar but the combustion zones share a common ring casing. The annular combustor is the most common type, with a continuous circular liner and casing without separate combustion zones.

Jet propulsion
Jet propulsion works by discharging a fluid to generate thrust in the opposite direction of the jet. There are two types of jet engines: air-breathing and non-air breathing. Air-breathing engines like turbojets, turbofans, ramjets, and pulsejets use atmospheric air, while non-air breathing rocket engines contain their own oxidizer and fuel. Rocket engines provide thrust through momentum change and pressure difference of the exhaust gases. They are self-contained and can operate in a vacuum but require a large amount of propellant.

Combustion chambers
The document summarizes the combustion chamber of a jet engine. It discusses how an air-fuel mixture burns inside the combustion chamber and how proper combustion and stabilization of the flame are essential for optimum engine power. It also describes the various requirements of a combustion chamber, including maintaining stable combustion over a wide range of operating conditions, high combustion efficiency, withstanding high temperatures, and minimizing pressure loss during combustion.
Gas Turbine
Gas turbines work by compressing air, heating it through combustion, and using the expanding hot gases to power a turbine. The key components are a compressor, combustion chamber, and turbine. In the compressor, air is compressed which is then mixed with fuel and ignited in the combustion chamber. The hot gases expand through the turbine, which converts the energy to power the compressor and provide output work to drive loads like generators or propellers. Variations include closed cycle systems which recirculate working fluid through a heat exchanger. Gas turbines have high power-to-weight ratios but lower efficiencies compared to reciprocating engines.
Rotary Engines
The document summarizes the key aspects of a Wankel rotary engine.

However, rotary engines can be more difficult to design to meet emissions regulations and typically have lower thermodynamic efficiency.
Turboprop
The turboprop engine has a compressor section that pressurizes air, a combustion chamber where fuel is burned, and a reduction gearbox that reduces the high rpm of the turbine to a lower rpm to turn the propeller more efficiently. The fuel nozzle injects fuel into the combustion chamber where an igniter plug ignites the fuel-air mixture to produce thrust to turn the turbine and propeller.

- Key advantages of gas turbines include greater power density, high reliability, and less maintenance compared to steam turbines. Disadvantages include lower efficiency and higher noise levels.
- Major applications are aircraft propulsion and electric power generation. Numerical examples are provided to calculate the performance of ideal and actual Brayton cycles.
centrifugal compressors overview
Centrifugal compressors work by imparting kinetic energy to a gas stream using an impeller, converting the dynamic energy into increased static pressure. They have advantages like high throughput capacity and efficiency over a wide operating range, but also disadvantages like discharge pressure limitations. Key components include impellers, diffusers, volutes, casings, shafts, bearings, and seals. Surge, a dangerous condition where flow reverses rapidly, must be controlled. Compressors can operate alone or in multi-stage arrangements with intercoolers. Common drivers are steam turbines, electric motors, and gas turbines.
Gas turbine and Jet Propulsion
Gas turbines operate by compressing air, adding fuel and igniting it to generate high-temperature gas, and expanding this gas through a turbine to power the compressor and provide output shaft work. There are various types including turbojets used in aircraft, turboprops which drive propellers via reduction gears, and turbofans which have a large fan at the front and achieve higher efficiency. Ramjets have no moving parts and rely solely on forward speed for compression, making them unable to produce static thrust.
Turbojet engines
Turbojets are jet engines that work by compressing air from intake, mixing it with fuel and igniting it in a combustion chamber. The hot gases produced are used to power a turbine which drives the compressor. The expanded gases are then ejected through a nozzle to produce thrust. Key components include axial or centrifugal compressors, combustion chambers, turbines and exhaust nozzles. Turbojets were used in early jet aircraft and provide high power-to-weight ratio but have high fuel consumption. Modern applications include Concorde which used turbojets due to their properties at supersonic speeds.

Jet propulsion
This document provides information about jet propulsion and different types of jet engines. It discusses the history of jet engines beginning with designs from ancient Egypt. The key components of a basic jet engine are described including the fan, compressor, combustor, turbine, mixer, and nozzle. Jet engines work by sucking in air, compressing it, adding fuel, combusting the mixture, and expelling the hot gases through a nozzle to produce thrust. The main types of jet engines are then outlined - ramjet, turbojet, turbofan, turboprop, and turboshaft - along with brief descriptions of each.
Steam Turbine and Condenser
1) Steam turbines are important prime movers that convert the thermal energy of steam into useful work. They operate using the principle that steam flowing over curved turbine blades imparts a force and causes the blades to rotate.
2) Steam turbines can be classified as impulse or reaction turbines depending on where the pressure drop of steam occurs. Impulse turbines only cause a pressure drop in nozzles, while reaction turbines cause a pressure drop both in nozzles and over rotor blades.
3) Steam condensers are heat transfer devices that condense exhaust steam from turbines using cooling water. The condensed steam, or condensate, is returned to boilers to be reused, saving water costs.
jet engines
Jet engines work by taking in air, compressing it, mixing it with fuel and igniting it to produce hot exhaust gases. These gases are then channeled through a turbine which powers the compressor. The fast moving exhaust gases exit through a nozzle to produce thrust that propels aircraft. Early jet engines were developed in the 1900s but came into widespread use after WWII to power military aircraft due to their superior speed over propeller planes. Modern jet engines include variants like turbofans used on most commercial planes.
Steam turbine and its types
This document discusses the Rankine cycle, which is a thermodynamic cycle derived from the Carnot vapor power cycle. It consists of four processes: 1) Isobaric heat supply in the boiler where water is heated to high pressure steam, 2) Adiabatic expansion of the steam in a turbine to produce work, 3) Isobaric heat rejection in the condenser where the steam is condensed back to water, and 4) Adiabatic pumping of the condensate back to the boiler to complete the cycle. The heat and work transfers are also defined for each process.
Turbo charger complete prensation
A turbocharger uses the heat energy from exhaust gases to drive a turbine, which spins an air compressor to force more air into the engine.

Turbochargers provide advantages like increased power and fuel efficiency but can experience failures if lubrication is inadequate.
Fundamentals of gas turbine engine

- Jet engines, such as turbojets, turbofans, turboprops and turboshafts use jet propulsion for forward thrust. They operate based on the Brayton cycle of isentropic compression, constant pressure heat addition, isentropic expansion, and constant pressure heat rejection.
- The basic workings of a turbojet engine involve air intake, compression, combustion, expansion
Axial flow compressor
This document discusses axial compressors. Key points:
- Axial compressors continuously pressurize gases using rotor blades that impart torque and stationary blades that slow the fluid and convert circumferential flow to pressure.
- They are integral to jet engines, ship engines, and power stations due to their high efficiency and mass flow rate.
- Compression occurs as the fluid moves axially through stages consisting of a rotating rotor and stationary stator, with the stator diffusing the fluid to increase pressure.
- Performance depends on a non-dimensional parameter that determines whether rotating stall or surge instability will occur at the stall line.
Compressor

2) Compressor types include centrifugal and reciprocating compressors. Centrifugal compressors use radial diffusers to increase pressure via Bernoulli's principle while reciprocating compressors use pistons in cylinders.
3) Capacity control methods for compressors include inlet guide vanes, blow-off valves, and modulating control to vary output between 100% to 10%. Operating parameters like inlet pressure and temperature influence compressor flow and power requirements
Aircraft propulsion
This document defines aircraft and propulsion, and provides examples of different aircraft types. It focuses on helicopters, describing their history and types.

The tail rotor controls direction and counteracts the spinning forces from the main rotor.
Industrial compressor
This document provides information about industrial air compressors. It discusses the key differences between pumps and compressors, with compressors being able to compress gases by decreasing their volume and increasing pressure.

The document then describes the working principles of positive displacement and dynamic compressors. It provides details on types of positive displacement compressors like reciprocating, screw, and vane compressors. Reciprocating compressors are explained in depth, covering components like cylinders, pistons, crankshafts and valves.
Superchargers and Turbochargers
This document discusses supercharging and turbocharging of internal combustion engines. It begins by explaining that supercharging and turbocharging aim to increase engine power output by supplying air or air-fuel mixture at a pressure higher than ambient pressure, thus increasing density and mass of the intake charge. It then describes the three main types of superchargers - centrifugal, roots, and vane types - and compares their characteristics. Turbocharging is introduced as using a gas turbine powered by exhaust gases to drive the supercharger, avoiding the need for a mechanical linkage. The principles of exhaust gas turbocharging for a single-cylinder engine are illustrated. Effects of supercharging such as increased power output and torque are also outlined.

The document examines the effect of dual injection on emissions in a combustor. Preliminary experiments tested a standard single injection combustor to establish a baseline. A dual injection combustor with top/bottom air inlets and side fuel inlets was then tested. Testing measured emissions like NO, CO, and CO2 at different air temperatures and fuel/air pressure ratios. The results found dual injection produced significantly higher nitrogen oxide emissions compared to single injection across most pressure ratios. While carbon monoxide emissions were generally similar, dual injection did not enhance mixing or reduce emissions as hoped. Future work could explore varying the fuel distribution between injectors to control reaction zones and flame characteristics.

Design and Analysis of Turbine Blades in a Micro Gas Turbine Engine
This paper is based on the design and analysis of turbine blades in a micro gas turbine engine. Micro-gas
turbine engines offer advantages over the other technologies for small-scale power generation. A combustor is the heart
of any engine; where in the micro gas turbine, it should be compact, simple, inexpensive and robust in construction. The
burned gases from the combustor pass through the turbine blades. The designing and manufacturing of the turbine
blades are very difficult when the blade angle, blade size and shape are considered. The design of the turbine blade
passages is broadly based on aerodynamic considerations and it is to obtain optimum efficiency, compatibility with
compressor and combustor design. For this, the specifications of many micro gas turbine engines are taken by
conducting a literature survey to get the design data for an apt turbine blade. By these values, the flow parameters of the
engine are obtained and are taken for analyzing purposes to get increased momentum thrust. Here, the design is done by
using the software CATIA and it is then exported to FLUENT for analyzing. The result shows that the estimated design
and performance is achieved.

AATE handout
This document outlines a 10-day lesson plan using spoken word poetry in a high school classroom. The plan aims to help students conduct self-reflection and character analysis, interpret artistic works, create and analyze text for performance, and respond intelligently to others' work. It begins with students creating "Personal Museums" by selecting meaningful artifacts and creating a video exhibit. Students then analyze themes in their lives and write slam poetry exploring a "thought" they want to convey. The plan involves workshopping poems multiple times and performing them for feedback, with a focus on discovery, community-building, and performance techniques.

Radio and Radar: Radar Continued - systems
Precision Approach Radar (PAR) allows air traffic control to guide aircraft to the runway with accurate guidance during poor weather conditions when visibility is limited. PAR consists of a rotating radar head that transmits beams to detect and track aircraft on their approach. Controllers can view the aircraft's elevation and azimuth scans on screens and guide the aircraft along the safe glide path to land. Instrument Landing System (ILS) provides automated guidance for aircraft landings without relying on ground controllers. ILS includes transmitters that provide horizontal and vertical guidance information to pilots, allowing them to align with the runway centerline and glide slope for landing. Weather radar detects precipitation and analyzes its motion and type to determine storm structure and potential for severe weather.
Radio and Radar: Radar
Radar and secondary radar systems use radio waves to detect objects and provide essential information to operators. Radar works by transmitting radio waves that bounce off targets and are received, allowing calculation of range and position. Secondary radar requires aircraft to carry transponders that respond to interrogations by transmitting a coded reply signal carrying additional data like identification and altitude. This improves detection range and allows transmission of emergency information.
Radio and Radar: Radio
1. Radio uses electromagnetic waves to transmit signals through air using a transmitter and receiver. Sound is converted to electromagnetic waves using modulation like AM and FM.
2. A radio receiver receives radio waves via an antenna and converts them back into audio using demodulation after tuning, amplification and detection stages. Superheterodyne receivers improve reception by translating the radio frequency to an intermediate frequency using beat frequencies.
3. FM receivers use a discriminator circuit for demodulation instead of a detector, as it is better for detecting small frequency differences representing the audio signal.
Piston Engines Types
This document discusses different types of piston engine configurations and layouts including single inline, Vee, horizontally opposed, and radial arrangements. It also covers 2-stroke and 4-stroke engine cycles, mechanical arrangements of petrol, diesel, Wankel, and radial engines including locations of intake, exhaust, pistons, crankshafts, and other components. Finally, it notes the wide range of sizes for piston engines from very small to large aircraft engines.
Piston Engines: Propellers
The document discusses propeller systems and how they generate thrust/lift. It explains that propeller blades work similarly to aircraft wings by generating higher pressure on one side and lower pressure on the other. The angle of attack of the blades can be adjusted to optimize thrust at different speeds. A controllable pitch propeller allows the blade angle to be adjusted in flight for takeoff, cruise, and landing. The helix angle, which is produced by the corkscrew motion of the blade tips, also affects thrust generation.
Piston Engines: Thrust Augmentation
1) A supercharger or turbocharger works by compressing the air-fuel mixture entering the engine cylinders, increasing power output.
2) In a supercharger, the impeller is driven directly by the engine crankshaft via a gear train. In a turbocharger, the impeller is driven by exhaust gases passing through a turbine.
3) Compressing the air-fuel mixture allows the engine to develop more power at high altitudes where atmospheric pressure and oxygen levels decrease.
Piston Engines: Cooling
Modern aircraft engines use air cooling or liquid cooling systems. Air cooled engines have cooling fins cast or machined onto the cylinder barrels and heads to increase the surface area exposed to airflow. Liquid cooled engines circulate coolant through a water jacket surrounding the cylinders and then to a radiator, where a fan aids heat transfer to the air. A thermostatic valve controls whether coolant circulates only through the engine or also through the radiator to regulate temperature.
Piston Engines: Ignition
Piston engines require an ignition system to produce sparks in the combustion chambers. A magneto generates high voltage sparks through rotating magnets and coil windings. It distributes the spark to each cylinder through a distributor block. Modern systems use electronic ignition for improved timing control. Spark plugs transmit the high voltage spark across an air gap to ignite the fuel-air mixture. Proper ignition timing and regular spark plug maintenance are important for reliable engine operation.
Piston Engines: Fuel
The document discusses piston engine propulsion systems, specifically focusing on carbureted fuel systems. It describes the basic components and functioning of aircraft and engine fuel systems, including fuel tanks, pumps, filters and carburetors. It provides details on how carburetors work to mix air and fuel, including the venturi, float chamber, needle valve, jets and throttle. It also discusses systems for idle, mixture control and maintaining the proper air-fuel ratio at varying conditions and altitudes.
Piston Engines: Oil
Lubricating oil is essential for piston engines to reduce friction and wear between moving parts. It also removes heat from the engine. There are two main types of lubrication systems - wet sump and dry sump. Wet sump systems carry the oil in the engine crankcase, while dry sump systems store oil externally. Pressure lubrication is the primary method used, relying on pumps to circulate pressurized oil through the engine. Filters help clean the oil before it reaches critical components.
Piston Engines: Operation
The document describes the four-stroke cycle of a piston engine. It involves the intake, compression, power, and exhaust strokes. In the intake stroke, air and fuel are drawn into the cylinder. In the compression stroke, the piston compresses the air-fuel mixture. In the power stroke, ignition causes combustion which forces the piston downward. In the exhaust stroke, the burnt gases are pushed out of the cylinder. This four-stroke cycle is repeated in each cylinder to produce rotational motion that can power a propeller. The timing of valve openings and ignitions is precisely controlled to maximize efficiency.
Piston Engines: Overview and Mechanical Arrangement
A piston engine produces power through controlled burning of fuel in cylinders which causes pistons to move back and forth. The piston motion is transmitted through connecting rods to a crankshaft, and the crankshaft's rotation is what produces the engine's power output and turns the propeller. Key components include the cylinders, pistons, connecting rods, crankshaft, and valves that control fuel intake and exhaust.
Jet Propulsion: Ignition
Spark plugs ignite the fuel-air mixture in reciprocating engines with a low-energy spark every revolution, but igniters in turbine engines are tailored to each specific engine model due to the difficulty of ignition. Igniters are designed specifically for each turbine engine model as an igniter for one engine likely will not function properly in another model due to the different ignition challenges of turbine engines compared to reciprocating engines.
Jet Propulsion: Fuel
This document discusses the key components and functioning of a turbine engine fuel system. It describes the two classifications of lubrication systems, wet-sump and dry-sump systems. It then focuses on explaining the fuel system, including the low pressure and high pressure fuel pumps, fuel-oil heat exchanger, fuel control unit, and fuel nozzles. The purpose of each component is outlined concisely.
Jet Propulsion: Oil and Lubrication Continued
Turbine engine lubrication systems have three sub-systems: the pressure system supplies clean oil at the proper pressure and temperature to bearings and gears. The scavenge system picks up used oil and returns it to the tank to be recirculated. The breather/vent system removes contaminated air from bearing housings through a de-oiler before blowing it overboard.
Jet Propulsion: Oil and Lubrication
There are two main types of turbine engine lubrication systems: wet-sump and dry-sump. Wet-sump systems store and circulate oil within the engine housing, while dry-sump systems use external tanks and pumps to store, cool, and circulate oil. Dry-sump systems are now more common and can be categorized as either hot-tank or cold-tank depending on whether oil is cooled before or after returning to the external storage tank. Both systems pressurize oil to lubricate engine bearings and gears and use scavenger pumps to return drained oil for recirculation.
Jet Propulsion: Temperature, Pressure and Velocity
This document describes the process of jet propulsion. It involves induction and compression to increase pressure and temperature, followed by combustion which further increases these parameters. The hot gases are then exhausted out of the engine, providing thrust based on the interplay between pressure, temperature, and velocity throughout the different stages.
Jet Propulsion: The Compressor and Turbine
The compressor takes in air and squeezes it across multiple stages to increase the air's pressure and temperature. Each stage consists of a rotor blade followed by stationary stator vanes that further compress the air. The compressor is powered by the turbine, which extracts energy from the engine's exhaust gas stream using impact or reaction turbine blades to drive the rotors. This high-pressure, high-temperature air is then used for combustion in the engine.
Jet Propulsion: Overview and Mechanical Arrangement
Jet engines work by compressing air, mixing it with fuel, combusting the mixture, and expelling the hot gases out of a nozzle using Newton's third law of motion. The key components of a jet engine are the compressor, combustion chamber, and turbine. Jet engines experience high temperatures that cause expansion and contraction of parts, so bearings are used to allow for differential movement and prevent stresses from developing in the rotating assembly.

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Jet Propulsion: Combustion Chamber
- 2. What happens in the combustion chamber?
- 3. • A combustor is a component or area of a jet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. • There are 3 types of combustors. • These are: Can, Cannular and Annular.
- 4. Can • Each "can" has its own fuel injector, igniter, liner, and casing • The air from the compressor is guided into each individual can. • It is then decelerated and mixed with fuel. • Finally it is ignited.
- 6. Cannular • Otherwise known as can-annular. • Similar to a can type. • Contains discrete combustion zones contained in separate liners with their own fuel injectors. • Unlike the can combustor, all the combustion zones share a common ring casing.
- 8. • This is the most common type used. • They do not have separate combustion zones and simply have a continuous liner and casing in a ring. Annular
