Mach-10 High Reynolds Number Development in the NSWC (Naval Surface Weapons Center) Hypervelocity Facility
Abstract
The present NSWC hypervelocity facility has two Mach number capabilities (10 and 14) which operate over a range of Reynolds numbers. The Mach-10 leg had a maximum Reynolds number capability of 5.4 x 10 to the 6th power/ft. The Reynolds number region of interest for Mach-10, encompassing the reentry flight regime, has been established as 0 to 100 x 10 to the 6th power. Using oversized models in the present 5-foot diameter test cell, this Reynold's number regime scales down to a 0 to 20 x 10 to the 6th power/ft. Requirement in the hypervelocity facility. The potential for a new, marketable testing capability, and the need to maintain a state-of-the-art facility, justified a major design effort to remove the constraints limiting the facility to the 5.4 x 10 to the 6th power/ft Reynolds number. This report documents this design effort, and subsequent performance of the new configuration. Originator-supplied keywords include: Gas dynamics; Run time; Structural analysis; Expansion wave; Flow restrictor; Particle separator; and Control valve.
