Research Synopsis: In recent years, the multi-disciplinary aspect of design has been considered wherein emphasis has been on improvements possible due to interaction between different disciplines. Simultaneous design and optimization approach for structural systems has been suggested in literature. This design approach enlarges the system boundary to encompass an integrated view of system design. The complexity lies in the interactions of the different sub-systems, but it reduces the design cycle time and ensures that mission requirements are met at the preliminary design stage itself. This research uses surrogate-based optimization for the control-oriented design problem, which focuses on the simultaneous `structural optimization/ controller design' problem. The three control synthesis techniques used in this study are H2, H-infinity, and Linear Parameter Varying (LPV) theory. This study considers the example of the design of a controller to account for the undesired effects of aerothermoelasticity in hypersonic flight and describes the process of control-oriented analysis to suggest a better thermal protection system and a controller for the vehicle.

Power plant Characterization for a MAV: The process of characterization of the different MAV propellers using an I.C. engine was carried out to study the characteristics of different propellers and in the long run to finally optimize the efficiency of the propellers and design propellers with the help of this data. With this in mind, a special setup for the propeller characterization and determination of the S.F.C. of the I.C. Engine was fabricated. Following the fabrication, necessary calibration experiments were performed and the results analyzed. After the results were analyzed it helped to select the propeller, engine and the fuel to maximize the e±ciency of the engine.
Development of a Fortran code to Estimate the Pitching Moment of an aircraft :
This code was validated with the available example and used to calculate the pitching moment of the MAV.

Aerodynamic Analysis of Mini Aerial Vehicle (MAV) using AVL:
AVL has a large number of features intended for rapid aircraft configuration analysis. The input geometric configuration files were created using the geometry of a MAV developed by IIT Bombay. Then the software was used to calculate various aerodynamic parameters like the variations of the lift and the pitching moments with the angle of attack and the slope of the pitching moment v/s roll rate curve. Xfoil was also used for the airfoil analysis.
