This document discusses the components and aerodynamics of helicopters. It describes that helicopters derive lift and thrust from horizontally revolving overhead rotors. The main components include rotor blades, a swashplate, mast, engine, transmission, tailboom, and skids. The rotor system consists of blades, grips, hub, and a mast connected to the transmission. The swashplate transfers non-rotating flight controls to the spinning rotor. Pilots control helicopters using collective and cyclic controls, with collective changing all blade pitches simultaneously and cyclic changing them unevenly.

How Helicopter work
INTRODUCTION:
While a helicopter is a far more complex machine than an aeroplane, the fundamental principles of flight are the same.
The rotor blades of a helicopter are identical to the wings of an aeroplane –when air is blown over them, lift is produced.
The crucial difference is that the flow of air is produced by rotating the wings – or rotor blades – rather than by moving the whole aircraft.
When the rotor blades start to spin, the air flowing over them produces lift, and this can cause the helicopter to rise into the air.
So, the engine is used to turn the blades, and the turning blades produce the required lift.

Automatic Transmission
An automatic transmission uses a torque converter, gear train, and hydraulic system to shift gears automatically based on engine load and vehicle speed. The torque converter connects the engine to the transmission and transfers power through fluid. It multiplies torque for better acceleration. The gear train includes planetary gear sets that provide multiple gear ratios. Hydraulic pressure acts through the transmission fluid to engage clutches and bands, producing gear shifts without driver input as the vehicle speed increases.
Power Transmission and Hydraulic Systems.pptx
There are two main types of hydraulic power transmission systems: hydrokinetic, such as the hydraulic coupling and the hydraulic torque converter, which use the kinetic energy of the liquid; and hydrostatic, which use the pressure energy of the liquid. The hydraulic coupling is a device that links two rotatable shafts.
Automatic gear transmission
Automatic transmissions use either planetary gears or a continuously variable transmission (CVT) to automatically shift gears without clutch pedals. Planetary gear transmissions contain a planetary gear set, torque converter, hydraulic system, governor, and computer controls to shift smoothly. The hydraulic system includes an oil pump, valve body, and shift valves to direct fluid pressure and activate clutches during gear changes. A CVT provides stepless gear ratios between maximum and minimum values for smooth shifting without discernible gear changes. Modern automatic transmissions precisely control shifting using computer monitors of throttle, speed, load, and other factors.

An automatic transmission uses planetary gears, a torque converter, and hydraulic and computer control systems to change gears automatically based on engine speed and load. It contains multiple gear sets that use different combinations of holding stationary gears to achieve various gear ratios. A hydraulic system uses pressurized fluid to engage clutches and bands to shift between gears smoothly. Computer controls monitor vehicle and engine parameters to determine optimal shift points. A continuously variable transmission can change through an infinite number of gear ratios to operate more smoothly than a transmission with fixed gears.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

Adaptive synchronous sliding control for a robot manipulator based on neural ...
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

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%.

Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

Helicopter aerodynamics
- 1. Helicopter Aerodynamics BAZIL M H S6 AERO
- 2. What is a helicopter ? • It is a type of aircraft which derives both lift and propulsion from one or more sets of horizontally revolving overhead rotors. It is capable of moving vertically and horizontally, the direction of motion being controlled by the pitch of the rotor blades.
- 3. Components of a Helicopter
- 4. Components of a Helicopter • Rotor Blade: The rotary wing that provides lift for the helicopter. • Stabilizer Bar: Dampens control inputs to make smoother changes to the rotor system. • Swashplate: Transfers non-moving control inputs into the spinning rotor system. • Cowling: The aerodynamic covering for the engine. • Mast: Connects the transmission to the rotor system. • Engine: Provides power to the rotor systems.
- 5. Components of a Helicopter • Transmission: Takes power from the engine and drives both rotor systems. • Greenhouse Window: A tinted window above each of the pilot seats. • Fuselage: The body of the helicopter. • Cabin Door: Allows access to the cabin and cockpit. • Skids: Landing gear that usually have no wheels or brakes. • Crosstube: The mounting tubes and connection for the skids.
- 6. Components of a Helicopter • Tailboom: Also known as an "empennage" is the tail of the helicopter. • Synchronized Elevator: A movable wing that helps stabilize the helicopter in flight.
- 7. Main Rotor System • Root: The inner end of the blade where the rotors connect to the blade grips. • Blade Grips: Large attaching points where the rotor blade connects to the hub. • Hub: Sits atop the mast, and connects the rotor blades to the control tubes. • Mast: Rotating shaft from the transmission, which connects the rotor blades to the helicopter.
- 8. Main Rotor System • Control Tubes: Push Pull tubes that change the pitch of the rotor blades. • Pitch Change Horn: The armature that converts control tube movement to blade pitch. • Pitch: Increased or decreased angle of the rotor blades to raise, lower, or change the direction of the rotors thrust force. • Jesus Nut: Is the singular nut that holds the hub onto the mast.
- 9. Swash Plate • It is a component of the helicopter which turns non-rotating control movements into rotating control movements.
- 10. Helicopter controls There are two types of controls: • Collective control • Cyclic control
- 11. Collective Control • In collective control, the pitch of the rotor blades are changed collectively i.e., the pitch of every rotor blade is changed by the same amount. • Doing this increases or decreases the lift that the main rotor supplies to the vehicle, allowing the helicopter to gain or lose altitude.
- 12. Cyclic Control • The left and right, forward and aft control. It puts in one control input into the rotor system at a time through the swash plate. • It changes the angle of attack of the main rotor's blades unevenly by tilting the swash plate assembly. On one side of the helicopter, the angle of attack (and lift) will be greater, and on the other sides angle of attack (and lift) will be lesser.
- 13. THANK YOU
