Aerojet 2012 модификация нк-33
Aerojet has nearly 50 years of experience with hydrocarbon propellants including engines for the Titan I and experience refurbishing and testing Russian NK-33 engines. The NK-33 was an oxygen-rich staged combustion cycle engine originally developed in the 1960s-70s for Russia's N1 moon rocket. Aerojet has worked to qualify the NK-33 for use on Orbital Sciences' Antares rocket, conducting tests of over 1,500 seconds total duration to demonstrate the engine can meet the rocket's duty cycle requirements. Oxygen-rich staged combustion engines provide higher performance than gas generator cycle engines and are more widely used internationally, while the U.S. has less experience with this engine cycle.
Cryogenic Rocket Engine
Cryogenics is the study of the operations at very low temperature (below −150 °C, −238 °F or 123 K) and the behaviour of materials at these temperatures.
marine power transmission
This document discusses marine power transmission systems. It describes how the transmission system transmits power from the ship's engine to the propeller, and how thrust from the propeller is transferred to move the ship. There are two main types of transmission: direct transmission, which uses a single shaft, and is suitable for low-speed diesel engines; and geared transmission, which uses gears to reduce the RPM of high-speed engines like medium and high-speed diesels, gas turbines, and electric motors. The document examines various prime movers, transmissions, and propulsor options used in marine transmission systems.
GSLV MARK 3
The document discusses India's GSLV Mark-III heavy lift launch vehicle. It has three stages - two solid rocket boosters as the first stage, a liquid propellant core as the second stage, and a cryogenic upper stage as the third stage. The document outlines the key features and thrust of each stage. It notes that the successful test of the CARE module, which separated from the cryogenic stage and landed safely, verifies technologies for ISRO's human spaceflight program to send astronauts into low Earth orbit. The first orbital flight of GSLV Mark-III is planned for 2016.
Azipod
The Azipod propulsion system, developed by ABB, uses podded electric motors that can rotate 360 degrees. This allows ships equipped with Azipods to maneuver more effectively than those using conventional propeller systems. Azipods have enabled cargo vessels and icebreakers to independently navigate harsh Arctic conditions via the Northern Sea Route. Their ability to rotate the vessel in any direction provides superior maneuverability and enables operations in heavy ice without assistance.
Isro’s advanced technology vehicle (atv) – light rockets for many experiments
The Advanced Technology Vehicle (ATV) is a light rocket developed by ISRO to carry payloads of 200-400 kg to altitudes of up to 800 km. It provides an excellent platform for upper atmospheric research and microgravity experiments. ISRO's first ATV test flight in 2010 was a success, carrying a passive scramjet engine to Mach 6. The next ATV flight will actively test ISRO's scramjet engine. As of 2014, ISRO had completed mission specifications and hardware development for the second ATV flight to demonstrate the active scramjet engine.
Liquid ppop..ppt(zak)
Liquid propulsion is the most advantageous for low earth orbiting vehicles and missiles. Using liquid propulsion, the flight path can be changed and is more effective.
Satellite sajith
Satellites orbit objects like planets to perform various missions. They have orbits that are either geostationary, asynchronous, or polar. Rockets are used to launch satellites into orbit and have multiple stages powered by liquid or solid propellant engines. The first stage provides maximum thrust at launch while subsequent stages have lower thrust and place the satellite into its proper transfer orbit using liquid or cryogenic engines before the final apogee kick motor releases it onto its mission orbit. Precise propulsion, communication, electrical power, and computer systems are required for successful satellite launch and operation in space.

A brief history of chemical rocket engines (thrusters) for spacecraft
This slide addresses chemical thruster on spacecraft and its history. A newer version with correction and addition is available: https://sites.google.com/view/akira-kakami/home
Solid Rocket Booster
The solid rocket boosters provide the main thrust to lift the Space Shuttle off the launch pad. Each booster has four hold-down posts securing it to the launch platform, which are released at liftoff. The boosters are ignited at T-0 and provide 80% of steering during ascent using thrust vector control from hydraulic gimbal actuators on their nozzles. Exactly 295 seconds after separating from the external tank, the solid rocket boosters fall into the Atlantic Ocean where they are recovered for reuse.
NASA SLS Solid Rocket Booster - Complete Explanation
The Space Launch System uses two solid rocket boosters that provide most of the thrust during launch. Each booster contains propellant made of ammonium perchlorate, aluminum, and binders that ignite and burn for 124 seconds. The boosters are jettisoned at an altitude of 45 km after which parachutes deploy to slow their descent into the ocean for recovery. A range safety system can destroy the boosters by remote command if needed for safety.

Metallic hydrogen could be a powerful new rocket propellant. It has the potential for high specific impulse compared to current propellants like liquid hydrogen and oxygen. Producing metallic hydrogen requires very high pressures, around 4-5 megabars. The author proposes using electron injection to reduce the critical pressure for producing metallic hydrogen. Experiments will study electron localization in solid hydrogen under pressure and aim to produce small amounts of metallic hydrogen to test its properties and metastability. Successful production of metallic hydrogen could enable new rocket and launch vehicle designs with much greater payloads and range.
Design and Assembly of an Economically-viable Near-Earth Asteroid Mining Robot
Presented in 2005
Outer space is a dangerous environment for humans to explore. However, unmanned spacecraft, the workhorses of NASA’s current space program, can travel through space with relative ease. By constructing an advanced robotic mining craft using a combination of current and easily obtained future technologies, a mining expedition could be made to one of Earth’s nearest neighbors, a near-Earth asteroid. Near-Earth Asteroids (NEAs) come in all shapes and in all varieties, which makes choosing the proper asteroid to mine a nontrivial affair: considerations must be made of asteroidal orbit, size, and composition. In addition, once the asteroid is reached by the mining craft, the physical and chemical act of mining an asteroid in deep space, far from places where “normal” conditions like gravity and an oxygenated atmosphere prevail, is substantially difficult; each mining implement, procedure, and storage technique must be chosen precisely. After the completion of the first mining mission, the mining craft will return to Earth orbit where it will transfer its precious cargo of ferrous metals, rarer-metals, and volatile gasses to an awaiting orbital station, thus avoiding any further need to launch minerals from Earth, which is extremely expensive. As a result of the asteroid mining and resource gathering operation, the National Aeronautics and Space Association will be able to expand the number of its deep-space operations exponentially.
How gliders fly
Gliders stay up in the air without an engine by having long, light wings that generate lift from rising warm air drafts, allowing gliders to glide long distances and at high altitudes as they catch bits of warm air rising off the ground.
Gliders for begineers
This document provides an overview of gliders and soaring flight. It discusses the origins of gliders dating back to ancient birds, as well as the Wright Brothers' early glider experiments. Modern gliders come in various forms including sailplanes for recreation, hang gliders that are foot-launched, and gliders that are almost ready-to-fly requiring only minor assembly. The document also describes different methods for staying aloft including using thermal lift from warm rising air or slope lift from winds hitting inclined land, in addition to ways of launching gliders such as with electric winches.

Solar Power Satellite System
This document discusses solar power satellites (SPS) as a solution for providing 24-hour power supply from space using wireless power transmission via microwaves. It describes issues with the stability of early phased array and SPS systems for accurate targeting. It proposes a simulation method called PAC (position and angle correction) to correct the position of SPS using measurements from receiver antennas on panel structures. The document outlines various advantages of SPS such as being unaffected by day-night cycles or weather and occupying no land area. However, it also notes challenges such as the complexity, large size, and high cost of a prototype SPS system.
Effect of Design Parameters on Ornithopter
This document discusses the design parameters of an ornithopter (a flapping wing aircraft). It first provides background on ornithopters and how they are modeled using blade element analysis. It then describes the specific parameters studied: forward speed, flapping frequency, total flapping angle, and incidence angle. The results show that lift is most influenced by incidence angle and forward speed, thrust is most affected by flapping frequency and forward speed, and drag increases with all parameters but is most impacted by total flapping angle.
Ornithopter
The document discusses ornithopters, aircraft that fly by flapping wings like birds. It describes the wing flapping mechanism, which uses a crank and connecting rod system to convert rotary motion into up and down wing flapping. Key components include dual crank systems for symmetrical wing movement and a tail for stability and steering. The ornithopter works by flapping its own wings to generate both lift and thrust, replacing a propeller. Potential applications include spying and studying bird flight.
Gliders
Gliders are aircraft that are supported in flight through the dynamic reaction of air against their lifting surfaces without an engine. Some gliders have small engines to extend flight or for launching. The Wright Brothers spent years experimenting with gliders to develop efficient airfoils and flight control before attempting powered flight. Modern gliders include sailplanes for recreation, hang gliders that are foot-launched, and almost ready-to-fly models that require minor assembly. Gliders find lift through thermals or slope lift and pilots circle to remain in rising air. Winches are commonly used to launch larger sailplanes a few hundred feet and electric motors now assist some gliders. Efficiency is measured by glide ratio and half the drag
HYBRID ROCKET COMBUSTION
The document summarizes research on using paraffin wax as the solid fuel and N2O/N2O4 as the oxidizer in a hybrid rocket system. It discusses the advantages and disadvantages of hybrid systems compared to liquid and solid fuel systems. The document reviews literature on hybrid rocket regression rates and combustion characteristics. It outlines the objectives and methodology of experiments to study the regression rate, mass consumption rate, motor pressure-time history, thrust, and specific impulse of the paraffin wax/N2O hybrid system.

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.
IDTechEx Research: Manned Electric Aircraft
About 20 companies make or will soon make electric aircraft. Nearly all are pure electric and fixed wing, the motorised hang glider and the self-launching sailplane being typical, with one hour endurance. A bigger value market being addressed is training planes and bigger still will be hybrid fixed wing and vertical takeoff aircraft hybrid and pure electric with the pure electric ones only managing 30 minutes. In these slides we discuss possible uses, improvements and other types too.

Thrust augmentation
This document discusses different methods of thrust augmentation in gas turbine engines, including water injection and afterburning. Water injection works by increasing the weight of air flowing through the engine, boosting thrust by 10-30%. Afterburning periodically increases thrust by burning additional fuel in the engine exhaust, similar to a ramjet, and requires components like fuel pumps, nozzles, and a variable exhaust nozzle. The document provides details on the construction and ignition systems used for afterburners.
SSA 2012—Developments at Schempp-Hirth
The document summarizes developments from Arcus and Quintus, two-seater and open class sailplanes respectively. For Arcus, preliminary considerations focused on comparable performance to reference sailplanes. Its design involved optimizing the airfoil, wing geometry, winglets, and aeroelastic properties. The first mold was begun in January 2009. Flight tests found it agile with good maneuverability. The Arcus M and E models are also introduced. For Quintus, the goal was an innovative open class self-launch sailplane with a high wingloading range for competition but also easy handling for other flights. Its wing was resized for lower weight but higher loading with water ballast. Both sailplanes went through prototy

Cryogenic rocket engine
Cryogenics is the study of materials at very low temperatures below -150°C. Cryogenic rocket engines use cryogenic fuels like liquid oxygen and liquid hydrogen that must be stored at extremely cold temperatures to remain liquid. The first country to use a cryogenic engine was the USA in 1963, while Russia developed its own in 1983. India has successfully developed its own cryogenic upper stage powered by the CE-7.5 cryogenic engine. Cryogenic engines offer very high energy density and clean, economical propellants but also present challenges related to storage and handling of the cryogenic liquids.

Slider Crank Mechanism for Four bar linkage
the slider crank mechanism is a particular four bar linkage configuration that exhibits both linear and rotational motion simultaneously. This mechanism is frequently utilized in undergraduate engineering courses to investigate machine kinematics and resulting dynamic forces. The position, velocity, acceleration and shaking forces generated by a slider crank mechanism during operation can be determined analytically. Certain factors are often neglected from analytical calculations, causing results to differ from experimental data. The study of these slight variances produces useful insight. The following report details the successful design, fabrication and testing of a pneumatically powered slider crank mechanism for the purpose of classroom demonstration and experimentation. Transducers mounted to the mechanism record kinematic and dynamic force data during operation, which can then be compared to analytical values. The mechanism is capable of operating in balanced and unbalanced configurations so that the magnitude of shaking forces can be compared. The engine was successfully manufactured and operates as intended. Data recorded by the device's accelerometers is comparable to calculated values of acceleration and shaking force.

A Suitable Structure to Control the System of Quad-rotor Miniature Aerial Veh...International Journal of Power Electronics and Drive Systems
1. The document presents a suitable control structure for controlling a quad-rotor miniature aerial vehicle (MAV).
2. It first establishes a six degree of freedom dynamic model and control equations for the quad-rotor. Then, it proposes two control structures - a single loop structure and a double loop structure.
3. The double loop structure is needed to control all six coordinates (x, y, z positions and roll, pitch, yaw angles) to allow the quad-rotor to fly precisely point-to-point, while the single loop can only control height and stability. Simulation and experimental results demonstrate the effectiveness of the proposed structures.Engine Kaveri

is matter around us pure? (class- 9th)
This document discusses the differences between pure substances, mixtures, and the various types of mixtures. It defines pure substances as homogeneous materials with a definite chemical composition, while mixtures contain two or more substances mixed together. Solutions are homogeneous mixtures whose composition can vary, while suspensions and colloids are heterogeneous mixtures. Several methods for separating mixtures like evaporation, centrifugation, and chromatography are also summarized.
the french revolution notes (class- 9th)
The French Revolution began in 1789 with the storming of the Bastille prison in Paris by revolutionaries. French society was highly unequal, with the majority of the population (the third estate) facing heavy taxation while the nobility and clergy were largely exempt. This, combined with Enlightenment ideas of equality and natural rights, led to growing unrest among commoners and the middle class. The Revolution abolished the monarchy and feudal system of France, establishing a constitutional monarchy then a republic, with the execution of King Louis XVI. A period of violence known as the Reign of Terror followed, led by Robespierre, before a Directory government was established under Napoleon Bonaparte.
tissues (class- 9th notes)
Tissues are groups of cells that work together to perform specific functions. There are four main types of tissues in animals and plants:
(1) Epithelial tissues cover and protect surfaces, and allow for absorption and secretion. (2) Connective tissues connect and support other tissues. (3) Muscle tissues allow for movement. (4) Nervous tissues receive and transmit electrochemical signals. Tissues are organized into organs that work together as organ systems to keep the organism functioning.

Three Major Industries
The document discusses three major industries - iron and steel, textiles, and information technology.
The iron and steel industry is a basic industry that uses iron ore, coal, and limestone as raw materials. These are smelted together in a blast furnace to produce pig iron, from which impurities are removed to produce pure iron and steel. Major producers include the US, UK, Russia, Japan, China, India, and Brazil.
The textile industry satisfies the basic need for clothing. It uses natural fibers like cotton, jute, flax, wool and silk as well as synthetic fibers. Major cotton producing countries include India, Pakistan, the US and China. The wool industry is prominent in
Air Pollution
Automobiles and industries are the major causes of air pollution. Automobile emissions release pollutants such as carbon monoxide, carbon dioxide, and chlorofluorocarbons. Industrial emissions also significantly contribute to air pollution through the burning of coal, which releases sulphur dioxide, carbon dioxide, smoke, dust and fumes. Long-term exposure to air pollutants can cause respiratory and heart diseases in humans as well as affect plant growth and reproduction. Reducing pollution requires alternative energy sources, improved vehicle emissions standards, and increased afforestation.
Cell Organelles with a cell song
Cells are the basic unit of all living things according to the cell theory. All organisms are made up of one or more cells, and cells only come from pre-existing cells. The main components of a cell include the cell membrane, cytoplasm, and nucleus. The cell membrane surrounds the cell and regulates what passes in and out. Within the cell is the cytoplasm, mainly composed of water, salts, and proteins. Organelles are structures that have specialized functions within cells, and include the nucleus, endoplasmic reticulum, ribosomes, vacuoles, Golgi apparatus, lysosomes, mitochondria, and plastids in plant cells.
Role of political parties in democray of India
Political parties are groups that contest elections and seek to hold power in government. They agree on policies and programs to promote collective good. The main components of a political party are leaders, active members, and supporters. Most Indians are critical of political parties and blame them for problems in democracy. Political parties are necessary to give citizens choices and form stable governments. The two types of political parties in India are national parties and state/regional parties. Political parties play important roles like contesting elections, forming governments, shaping public opinion, and providing access to government programs. While ruling parties govern and address people's concerns, opposition parties scrutinize the government and prevent abuse of power. The major national political parties in India are the Bharati

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

PSLV C23
- 3. PSLV was designed and developed in the early 1990s at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram,Kerala. The inertial systems are developed by ISRO Inertial Systems Unit (IISU) at Thiruvanathapuram. The liquid propulsion stages for the second and fourth stages of PSLV as well as the reaction control systems are developed by the [Liquid Propulsion Systems Centre (LPSC)] at Mahendragiri (Tirunelveli), Tamil Nadu. The solid propellant motors are processed at Satish Dhawan Space Centre (SHAR) which also carries out launch operations.

- 12. •The PSLV has four stages using solid and liquid propulsion
- 13. The first stage is one of the largest solid-fuel rocket boosters in the world and carries 138 tones of Hydroxyl-terminated polybutadiene (HTPB) bound propellant with a diameter of 2.8 m. The motor case is made of maraging steel. The booster develops a maximum thrust of about 4,430 kN. Six strap-on motors, four of which are ignited on the ground, augment the first-stage thrust. Each of these solid propellant strap-on motors carries nine tones of HTPB propellant and produces 677 kN thrust. Pitch and yaw control of the PSLV during the thrust phase of the solid motor is achieved by injection of an aqueous solution of strontium perchlorate in the nozzle to constitute Secondary Injection Thrust Vector Control System (SITVC). The injection is stored in two cylindrical aluminum tanks strapped to the solid rocket motor and pressurized with nitrogen. There are two additional small liquid engine control power plants in the first stage, the Roll Control Thrusters (RCT), fixed radically opposite one on each side, between the triplet set of strap-on boosters. RCT is used for roll control during the first stage and the SITVC in two strap-on motors is for roll control augmentation.
- 15. The second stage employs the Vikas engine and carries 41.5 tones (40 tones till C-5 mission) of liquid propellant – Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidizer. It generates a maximum thrust of 800 kN
- 17. The third stage uses 7 tones of HTPB-based solid propellant and produces a maximum thrust of 324 kN. It has a Kevlar-polyamide fiber case and a submerged nozzle equipped with a flex-bearing-seal gimbaled nozzle (±2°) thrust-vector engine for pitch & yaw control. For roll control it uses the RCS (Reaction Control System) of
- 19. The fourth and the terminal stage of PSLV has a twin engine configuration using liquid propellant. With a propellant loading of 2 tones (Mono-Methyl Hydrazine as fuel + Mixed Oxides of Nitrogen as oxidizer), each of these engines generates a maximum thrust of 7.4 kN. Engine is gimbaled (±3°) for pitch, yaw & roll control and for control during the coast phase uses on-off RCS. PSLV-C4 used a new lightweight carbon composite payload adapter to enable a greater GTO payload capability.
