Multidisciplinary Design Optimization of Hypersonic Transport Configurations using Waveriders

Abstract: A multidisciplinary design method for generating hypersonic transport (HST) configurations using waveriders is presented. Waveriders generated from osculating cone flowfields are used as the initial platform for the vehicle, and various modifications required for the mission are implemented. The propulsion system assumes the use of ramjets and lowbypass turbofans with hydrocarbon fuel. Empirical estimates of the structure weight of the configuration are combined with a method for calculating the total mission … Show more

“…As a result, a waverider could obtain a large L/D as well as a uniformly compressed flowfield for the inlet of the scramjet. Thus, the waverider-based airframe-engine integrated design had been consider as the most competitive candidate of hypersonic vehicle configurations [10][11][12][13][14][15][16][17] . In addition, to reduce the overall drag and achieve favorable conditions for propulsion system at hypersonic speeds, the engines must be highly integrated with the airframe.…”

“…They employed osculating cone waveriders as the basis not only to provide increased aerodynamic efficiency, but also because of the fact that the inverse design process allows the upper surface to be designed around the mission payload requirements. More recently, a further study that include several improvements incorporated into the design method to provide increased fidelity of the results and the utilization of a genetic algorithm optimization technique to more thoroughly explore the design trade space was published by them 18 . A primary shortcoming of the scramjet is that it is unable to generate static thrust (thrust at zero velocity) and have poor performance at low Mach numbers.…”

“…Because there is no flow spillage from the lower surface to the upper surface, a waverider could obtain a large lift-to-drag ratio (L/D) as well as a uniformly compressed flowfield for the inlet of the scramjet. Naturally, the ventral intake layout by using a waverider as the forebody and by placing scramjets beneath the vehicle has aroused great concern of scientists and engineers [6][7][8][9][10][11][12][13][14][15][16][17][18] . O'Neill and Lewis 6 presented several engine-airframe integrated vehicles based on waverider configurations that generated from conical flowfields.…”
