Session 3 at SOAR by AVEMBSYS

            Avembsys training resumed after a long break and everybody seemed ready to kickstart the session with open ears and mind. The session began with Jawad brushing up a few basics of C programming. He covered topics like data types, identifiers, pointers and command line arguments.
            Our Techlead then took over the session. We first discussed about what is Flight Management System(FMS) and how electromagnetic pulse is used in electronic warfare. An electromagnetic pulse is used in overcoming an enemy assault. The FMS can guide the aircraft's autopilot along the flight plan fed into the system.
            We then looked at the various aerodynamic basics. The core fundamental concepts are based on ninth standard physics such as mass,
weight, force, momentum, moment, couple, density, temperature, viscosity
and pressure.
             Viscosity is the resistance of a fluid being deformed due to pressure.
It increases with speed, an example of which is best understood by keeping your hand outside a moving vehicle, i.e., the viscosity of air increases. Viscosity of liquid decreases with increase in temperature and for gas it increases with increase in temperature. Pressure is the force acting per unit area. An aircraft's airspeed indicator is operated by the static pressure system and the pitot pressure system.
              How does an aircraft fly?
The jet engine sucks the air, forms a small jet of air and rejects it at the back. This provides the thrust required for the aircraft to fly. While take off the lift is achieved by the difference in slope at the top and bottom of the wings, which creates a low pressure on top and high pressure at the bottom of the wing.
We then saw a view of the aircraft which consists of the following, a cockpit, fuselage, spoilers, aileron,flaps,elevator,rudder,vertical and horizontal stabilizer, wing and jet engine.
              Next we discussed about cloudburst. It is a form of precipitation, and is very dangerous for aircrafts to land during a cloudburst. We had a 30 minute lunch session. In the post lunch session we discussed about the projects and were divided into two groups to handle two basic projects. One was based on hardware and software and the other was a software project. I chose to work on the former.
              The project is based on data transmission and reception with two seperate modules using 8051 microcontroller interfaced with an LCD display and a keyboard. Also light sensors are to be used to detect data being transmitted and to send any data to the transmitting module.
              Finally we saw a video of how an aircraft takes off and lands vertically and another video or i must say we saw a documentary of the horrific crash of a french commercial aircraft which took place in the year 1988. We analysed the different causes or reasons for the crash and it gave us a good insight about the different intricate details that has to be taken care before flying an aircraft. With this the 3rd session came to a close. I look forward to gain more knowledge and expertise in this domain.
