Abstract
Waverider is a lifting body tailored to create high lift to drag ratio in high-speed flow. Present work includes optimization of power law derived waverider using TLBO for a design altitude of 30 km at zero design angle of attack and for a range of angle of attack from −2 to 6 for inviscid, laminar and turbulent cases at design Mach number from 5 to 8. Optimized waverider geometry parameters for all three cases are compared for two objective functions: (a) maximization of lift to drag ratio and (b) maximization of lift to drag ratio and volume along with minimization of heat flux (represented by wetted area in present study). Dependence of n, δ, and λ (design variables) on lift to drag ratio is discussed in detail. Numerical and experimental validation of the analytical model shows a close match with the data available in the literature. Despite having some limitations, this model serves as a valuable design tool in the conceptual phase to arrive at optimized waverider configurations. Optimization function can be changed according to the designer’s requirements.
