AIRCRAFT SPOILER MOTION MECHANISM SYNTHESIS

In all civil aircrafts wings there is a part called "air brakes", also named "spoilers", which
are principal integral elements of an aircraft wing. An aircraft wing possess a unique
geometrical cross section termed an "airfoil". This unique geometrical design creates lift force
which counteracts the aircraft weight as air flows above and below the wing possessing the
airfoil geometry . Air brakes are almost flat metal panels assembled on the wing top
surface which fully deploy upon aircraft momentum or decelerating the aircraft via resisting the
aircraft forward motion. Additionally, air brakes could be partially deployed during flight to
reduce the aircraft speed. Partial deployment of air brakes causes slight disturbance of air
flowing on top of the wing leading to required speed reduction. Experimental testing illustrated
the effectiveness of air brakes in reducing an aircraft stopping distance as compared to
conventional braking without deploying airbrakes.

Hybrid Maximum Power Point Tracking System for Off Grid Photovoltaic Cells

In the present project the application that is used to consume the power derived from the photovoltaic system is water pumps system. Furthermore, the seasonal and enduring movement of planet earth heavily affects the irradiation intensity on photovoltaic systems. Sun-tracking system can be used to move the photovoltaic system to make up for the planet earth movements to keep the best orientation of the photovoltaic system relative to the sun. Thus, in this project the experiment held is for using sun-tracking system along with electrical maximum power point tracking subsystem to have the optimum energy to be gained along the day.

This was a team project for bachelor thesis.

A full model have been developed and it was working very well.

Stress Analysis on Thin-Walled Single Weld Miter Pipe

This project has been done during my work as Undergraduate Research Assistant. The project was done using Abaqus. The target was to have stress-analysis results for a miter pipe that has topological challenge and used in nuclear applications.

ASME standard was used to test the results using also the twice-elastic slope method.

Geometric non-linearity was taken into consideration.

Maximum Power Tracking using PID Controller

The renewable energy is recently being used in numerous life applications. The solar energy is one of the most famous known renewable clean energy source. Therefore, developing in the field of solar energy production is essential for the futuristic products. In this project, the main objective was to obtain the highest efficiency from the solar panels through tracking the highest power that can be obtained. In this paper, a parametric study was conducted to determine the best algorithm for controlling of the energy input to the solar panels to derive the highest power to be later stored. The controller mainly had options of PID controlling algo-rithms, to define the best algorithm of them though the study. The conducted study showed that the best algorithm is PID.

Power Transmission Shaft

Power Transmission Shafts has various applications like Power Transmission shaft of a vehicle’s gearbox, Helicopter Transmission Shaft, and three collinear shafts in the jet engine of a civil airplane which are Low Pressure Shaft, Intermediate Shaft, and High Pressure Shaft.
In this project the power transmission shaft of gear shifting of manual transmission vehicle is discussed.

The shaft is used to rotate at a specific range of velocities determined by the ability of the engine, but transfer the power from the engine to the wheel. The vehicle starts from 0 m/s until some high speed as a top speed. For the low velocities, a lot of torque are required to make the vehicle move at the low velocities, but for higher velocities the speed of rotation is required more. i.e. the velocity is inversely proportional with the torque required to move the vehicle. The input of the rotation starts from the engine rotation, to reach the wheels through the gearbox passing through a specific gear mounted on the shaft of power transmission. The wheel and the vehicle has various kinds of resistance to motion like the drag force and the friction force. The output of the transmission shaft is rotation but with various values of rounds per minute and torque. The value of the rounds per minute of the output shaft and the torque depends mainly on the gear that is being used for the power transmission which is mounted on the shaft. Smaller gears have more rounds per minute and less torque when they are the meshed gears to the system, and the vice versa for the larger gears. The input comes from the combustion engine of the vehicle moves to the gearbox, then to the motion shaft to make the output as rotational motion of the wheel. The shaft is fixed to two bearing that are responsible to make allow the rotational motion of the shaft to be as smooth as possible during operation with the least friction available.

Focusing only on the method of the co-simulation which will be helpful to use in various kinds of robots and another applications that requires control. The report explains these steps using MSC Adams 2017 Student Edition, MATLAB 2018a, and Solidworks 2016. The features might have been available on older versions of the aforementioned software programs. The robotic arm used is the famous Kuka kr16 6 degrees of freedom arm. This arm has 6 rotational joints. According to the task given, only one joint was controlled and its results were monitored. The arm was moved by 10 degrees about x-axis clockwise.

Solar Tracker system

Our model main function is to make use of the maximum amount of solar light energy in the phase of the electric energy by controlling the tilting and orientation of the solar panel attached to a designed mechanism. The mechanism movement is controlled by two servo motors each one is responsible for a certain kind of motion. Our design contains two servo motors one of them makes a 360 degree of rotation around the vertical axis of the main pole of the body, the other one is responsible of the tilting of the solar panel with 180 degrees in the rotation axis around the horizontal shaft. The program used to control the motors in uploaded on an Arduino Chip and a circuit composed of LDR sensors is mounted on the design in order to make a difference in the resistances and then to determine the direction of the sun light to implement the program codes.

This was part of BSc course group work.
