作为NASA Hyper-X计划的一部分，机身一体化超燃冲压发动机试验已经在NASA兰利8英尺高温风洞中在马赫数7的飞行条件下完成。该试验为Hyper-X研究飞行器（X-43）的马赫数7飞行试验提供了发动机性能和可操作性数据，以及设计和数据库验证，该飞行器将提供有史以来第一个机身一体化的超燃冲压发动机飞行数据。Hyper-X飞行发动机是一台复制的马赫数为7的X-43超燃冲压喷气发动机，安装在机身结构上，该结构复制了从飞行器前缘到飞行器后缘的整个三维推进流路。该模型还进行了测试，以验证和确认完整的飞行样发动机系统。本文介绍了受到类似飞行条件的子系统，并提供了支持数据。这次测试的结果有助于降低X-43在7马赫飞行时的风险。
Airframe-integrated scramjet engine testing has been completed at Mach 7 flight conditions in the NASA Langley 8-Foot High Temperature Tunnel as part of the NASA Hyper-X program. This test provided engine performance and operability data, as well as design and database verification, for the Mach 7 flight tests of the Hyper-X research vehicle (X-43), which will provide the first-ever airframe-integrated scramjet data in flight. The Hyper-X Flight Engine, a duplicate Mach 7 X-43 scramjet engine, was mounted on an airframe structure that duplicated the entire three-dimensional propulsion flowpath from the vehicle leading edge to the vehicle trailing edge. This model was also tested to verify and validate the complete flight-like engine system. This paper describes the subsystems that were subjected to flight-like conditions and presents supporting data. The results from this test help to reduce risk for the Mach 7 flights of the X-43.
