Mach 10/14 Operations in the NSWC Hypervelocity Wind Tunnel Number 9 (Vertical Heater Vessel Leg)
The original design of the Tunnel No. 9 Hypervelocity Facility called for three distinct Mach number capabilities; namely Mach 10, Mach 15, and Mach 20. The Mach 15 (now Mach 14) and Mach 10 legs are operational. However, problems have been encountered in using horizontal heater vessel to store hot...

| description | The original design of the Tunnel No. 9 Hypervelocity Facility called for three distinct Mach number capabilities; namely Mach 10, Mach 15, and Mach 20. The Mach 15 (now Mach 14) and Mach 10 legs are operational. However, problems have been encountered in using horizontal heater vessel to store hot test gas in the Mach 10 leg. A potential solution was to use the existing Mach 10 nozzle in combination with the Mach 14 heater vessel. After several design changes were implemented to mate the Mach 10 nozzle with the Mach 14 heater vessel, tunnel tests were conducted which demonstrated operational feasibility. However, unexpected high pressure drops resulted in a low Reynolds number. This report documents both Mach 10 and Mach 14 testing capabilities utilizing the Mach 14 heater vessel, and the analyses and testing on which the capabilities are based. |
