1. CFD Investigation of Momentum Injection Control past a Streamlined Body.• Moving surface boundary layer control technique has been used on the aerofoil.• A rotating disc has been kept at the leading edge of the aerofoil to inject momentum on the upper surface of the aerofoil.2. Close loop control of Momentum Injection on Rotating Disc.• Multiple sensors are placed behind the body to obtained flow properties.• This information can be passed to actuator (Rotating disc) through an algorithm.

1. Parachute Drag Area Calculation behind Tejas (LCA) aircraft.• A drag parachute technique has been used on the Tejas aircraft to stop it while landing.• Different drag area of parachute has been implemented, to optimize the performance.2. Test Performance Analysis for Tejas.• Analysis such as; take-off, climbing, cruise, descending, landing etc. to see the performance of Tejas aircraft in different flight condition.• C and MATLAB code developement to perform these analysis as well as for parameter studies such as lift and drag co-efficient.3. Different Graphic User Interface (GUI) developement with the help of MATLAB for customers.
