Airbreathing hypersonic vehicle design and analysis methods

Abstract

The design, analysis, and optimization of airbreathing hypersonic vehicles requires analyses involving many highly coupled disciplines at levels of accuracy exceeding those traditionally considered in a conceptual or preliminary-level design. Discipline analysis methods including propulsion, structures, thermal management, geometry, aerodynamics, performance, synthesis, sizing, closure, and cost are discussed. Also, the on-going integration of these methods into a working environment, known as HOLIST, is described.

Optimization and Analysis on Trajectory with Multiple Constraints for Hypersonic Air-vehicle

“…Where, 1 u is the auxiliary control variable of angle of attack, and the treatment method is the same as that for angle of heel and fuel equivalence ratio. As the process constraint obviously contains the control variable, the algorithm will have a strong robustness and convergence.…”

“…Recently, with the development of propulsion, material and control technology, the hypersonic air-vehicle, as an advanced aerial air-vehicle, has been becoming the wide focus of various global military powers [1] . As the hypersonic air-vehicle experiences a large scope of height and speed in the flight, and is strictly constrained by heat proof, structure, dynamic pressure, overload, and so on.…”
