Waverider Vehicle Optimization with Volumetric Constraints for Sonic Boom

摘要

An optimization process has been developed for the Osculating Flowfield waverider generation method that permits the design of wavcriders with physical characteristics matching desired area and volume distributions. Since a wide number of waverider classes, such as Caret, Conical, and Osculating Cones waveriders, are all subsets of the Osculating Flowfield approach, this new capability has broad applicability. This paper will present the development of the new process using two methods to generate a sonic boom footprint metric which drive the waveriders' physical characteristics to have a desirable streamwise distribution of the sum of local volume and integrated lift from the nose. Additionally, numerical optimizations has been performed to optimize waveriders designed to a specific Mach number while being constrained to the desired volumetric distributions for favorable sonic boom performance.
