After a long break the AVEMBSYS session started again on 5th January 2011. The session started with discussion on basics of C programming by our friend.After that sir gave us idea about electronic warfare in that we came to know how a pulse of high density electromagnetic wave is used to destroy the enemies electronic devices. Then we moved to the basics of aerodynamics which included basic concepts of mass , force momentum, moment ,couple, density, temperature, viscosity and how viscosity increases with increase in speed. After that we got an idea about the static stagnation and gauge pressure. In that gauge pressure/absolute pressure that is pressure at a point static pressure which refers to measure of purely random motion of molecule in gas, and total/stagnation pressure which points to pressure at a point where the fluid element is slowed down to zero.Then we came to know about PITOT tube and its principle and how it is used for the measurement of the speed of the aircraft. After that we discussed concepts related to gas such as gas law, isothermal process , adiabatic process. And then we came to know about different types of altitude Pressure ,True or Sea Level altitude and Absolute. Then we discussed on aircraft attitude ,center of gravity,aerodynamic center,center of pressure.After that we came to know about MACH NUMBER which is a measure of speed of the aircraft.Which is the ratio of speed of the body and speed of sound.Then details were given about how an aircraft fly and how it produces the lift ,came to know how the shape of the aircraft helps to produce sufficient lift by creating low pressure at the bottom and high pressure at the top,and also how an aircraft produces thrust by using a jet engine which emit a fast stream of fluid in opposite direction.Next we learnt about the various parts of the aircraft. How the lift is created, also how rotate, drag, adjust in the lift and the six degrees of freedom were demonstrated with a diagram showing the various parts such as flaps, slats, wings, spoilers, rudder, aileron etc.Discussions were done over lift coefficient and how lift first increases with angle of attack and after certain angle it starts decreasing.The different moments acting on the aircraft were seen as Pitching, Rolling and Yawing.
The Session ended with a video about how the VTOL which is Vertical Take-Off and Landing.After that we discussed about cloud burst , air pockets.The 3rd session winded with a video of the crash of French airbus A320.A discussion of the projects preceded the end of the session.The students who were interested in hardware were given an assignment to work on the Transceiver system using an 8051 Micro-controller and also developing a sensor to detect the crossing in range of it.As for the software students we were given a brief about the Software Development Life Cycle and the V-Model that is being used on to develop Critical Systems.
