Abstract/Summary Many vehicle design studies focus on optimizing Hypersonic Accelerating Airbreathing vehicles for maximum performance but typically trim is not a primary concern. Vehicle longitudinal trim is often obtained by using trim elevons resulting in unwanted trim drag. As it is difficult to obtain high thrust from scramjet engines at high Mach numbers, trim drag reduction is important for accelerating vehicles. This study is based around maximizing the performance of an airbreathing 2nd stage Winged Cone Vehicle, as part of a three-stage rocket-scramjet-rocket launch system for payload masses of the order of 100kg. The concept of a minimum trim vehicle is introduced, where it is desired to alter the vehicle planform to reduce the amount of elevon trim required along the trajectory. It is shown that by including the trajectory and the requirement for the vehicle to be longitudinally trimmed into a multidisciplinary analysis and optimization study the performance of the vehicle can be improved over a conventionally optimized design with post optimization trim.
