Hyper-X: Flight Validation of Hypersonic Airbreathing Technology

TLDR

NASA’s Hyper‑X program focuses on advancing hypersonic air‑breathing technology from laboratory to flight testing. The program aims to transition hypersonic air‑breathing vehicle technology from lab to flight, concentrating on Mach 5, 7, and 10 vehicle development and validation. The study outlines the program’s history, objectives, schedule, and ongoing development of Mach 5, 7, and 10 vehicles, with detailed flight‑condition evaluation of the Mach 7 platform. Significant experimental data and concept validation have been achieved, with the Mach 7 vehicle’s flight‑condition evaluation nearing completion to support design method validation.

Abstract

This paper provides an overview of NASA's focused hypersonic technology program, i.e. the Hyper-X program. This program is designed to move hypersonic, air breathing vehicle technology from the laboratory environment to the flight environment, the last stage preceding prototype development. This paper presents some history leading to the flight test program, research objectives, approach, schedule and status. Substantial experimental data base and concept validation have been completed. The program is concentrating on Mach 7 vehicle development, verification and validation in preparation for wind tunnel testing in 1998 and flight testing in 1999. It is also concentrating on finalization of the Mach 5 and 10 vehicle designs. Detailed evaluation of the Mach 7 vehicle at the flight conditions is nearing completion, and will provide a data base for validation of design methods once flight test data are available.
