    A hypersonic aeroheating calculation method based on inviscid outer edge of boundary layer parameters The engineering method is widely used to make fast aeroheating prediction, especially at the initial stage of the aircraft design. The engineering method is applied to the boundary layer to reduce the computational cost and the Author: ZhuXuan Meng, Hu Fan, Ke Peng, WeiHua Zhang, HuiXin Yang. An overview of basic aeroheating design issues for Reusable Launch Vehicles (RLV), which addresses the application of hypersonic ground-based testing, and computational fluid dynamic (CFD) and engineering codes, is presented. Challenges inherent to the prediction of aeroheating environments required for the successful design of the RLV Thermal Protection .

      Abstract. Disturbance level measurements are carried out in the Hypersonic Ludwieg Tube Braunschweig (HLB) at \(\text{ Ma } = \) considering three shapes of stagnation point probes (SPP) and two different types of high speed surface sensors. Navier Stokes mean-flow solutions are produced for the flow around the front shapes to increase the understanding Cited by: 1. BibTeX @MISC{Kleb98aeroheatingpredictions, author = {William L.

    The aero-thermal analysis of a hypersonic vehicle is of fundamental interest for designing its thermal protection system. The aero-thermal environment predictions over several critical regions of the hypothesized lifting body vehicle, including the stagnation region of the nose-cap, cylindrically swept leading edges, fuselage-upper, and fuselage-lower surfaces, are by: 8. The X program seeks to demonstrate an autonomously returned orbital test flight vehicle to support the development of an operational Crew Return Vehicle for the International Space Station. The test flight, anticipated in , is intended to demonstrate the entire mission profile of returning Space Station crew members safely back to earth in the event of medical or .
