“…This facility has a nozzle, which provides for the Mach number M = 14 and has a diameter of 0.43 m at the outlet, and a conical (6) nozzle with a diameter of 0.6 m at the outlet for flows with the Mach number in the range from 15 to 20 [87].…”

“…The shock-wave compression was realized in the VKI Longshot Free-Piston Tunnel [87] developed to produce hypersonic flows with high values of the Reynolds number. This facility has a nozzle, which provides for the Mach number M = 14 and has a diameter of 0.43 m at the outlet, and a conical (6) nozzle with a diameter of 0.6 m at the outlet for flows with the Mach number in the range from 15 to 20 [87].…”

Various methods of gas compression are reviewed, which are intended for heating the gas. Special attention is given to units of nonisentropic compression of the mechanical heat-engineering type, in which the gas is transferred from chamber to chamber in order to increase the temperature. The units are subdivided into classes or systems, namely, those of impulse, pulse-periodic, and continuous operation. Methods are discussed of mathematical description of processes occurring in units of this type, including analytical investigation of simplified qualitative models and numerical simulation in more complex cases close to reality.

“…The test conditions decay monotonically during 10-20 ms of running time as the gas trapped in the reservoir exhausts through the 6" half-angle, conical nozzle into the test section. A fuller description of the tunnel has been given by Richards & Enkenhus ( 1970). The present tests were made at a nominal Mach number of 16 and all the data were taken 2 ms after the peak flow conditions, \ A .…”

A sharp wedge expansion flap was tested in the von Kámán Institute Long-shot tunnel at Mach 16 and data on the wall pressure and heat transfer were obtained. Pitot pressure measurements in the boundary layer just ahead of the expansion flap were also made. The surface data are compared with predictions from a characteristics solution for the boundary-layer expansion and from a simple heat-transfer theory.
