Confirmation of Candidature - Rocket Angle of Attack and Bending Load

The aerodynamic loading on sounding rockets launched by Mobile Rocket Base (MORABA) is currently evaluated using estimation techniques such as the "DLR Method" and (Flight, Loads, Moments, and Deflections) FLMD++. Such techniques are reliant on semi-empirical methods which results in significant overestimation of structural loading. Consequently, notable safety margins must be included into the rocket design which ultimately leads to reduction in rocket performance.

This research proposes to develop an empirical correlation between the angle of attack and aerodynamic loading based on wind tunnel experiments, which will enhance existing estimation methods. The objective will be achieved through the development of a Flush Air Data Sensing System (FADS) and a Flight Load Measurement System (FLMS) under various wind tunnel conditions, with the potential for future flight testing. Additionally, these systems will be applied to hypersonic vehicles geometries to predict dynamic changes in the angle of attack and measure loading on control surfaces, critical for achieving high maneuverability during flight.
