Hyper-X Research Vehicle Experimental Aerodynamics Test Program Overview

摘要: This paper provides an overview of the experimental aerodynamics test program to ensure mission success for autonomous flight Hyper-X Research Vehicle (HXRV). The HXRV is a 12-ft long, 2700 lb lifting body technology demonstrator designed demonstrate first time fully airframe integrated scramjet propulsion system. Three flights are currently planned, two at Mach 7 and one 10, beginning in fall 2000. research vehicles will be boosted prescribed engine point where they separate from booster, stabilize. initiate test. Following 5+ seconds powered 15 cowl-open tares, cowl close vehicle fly controlled deceleration trajectory which includes numerous control doublets in-flight aerodynamic parameter identification. reviews preflight testing activities, wind tunnel models, rationale. risk reduction sample results tests supporting hypersonic through subsonic termination.
