The Hypersonic Pulse Facility (HYPULSE) is operated by Purdue University in West Lafayette, Indiana on the campus of Purdue's Maurice J. Zucrow Laboratories. HYPULSE was formerly operated as NASA's HYPULSE by the General Applied Science Laboratory (GASL) in New York before it was donated to Purdue in 2020 by Northrop Grumman. The HYPULSE ...
The New York City Department of Transportation owns and operates almost 800. [1] The Metropolitan Transportation Authority, Port Authority of New York and New Jersey, New York State Department of Transportation and Amtrak have many others. Many of the city's major bridges and tunnels have broken or set records.
'Rolling road' moving ground plane. Part of the UK National Wind Tunnel Facility: MARHy wind Tunnel [41] Operational Diameter 5 m (16 ft) by 2.5 m (8 ft 2 in) Hypersonic/supersonic rarefied wind tunnel. No limit running time. Reynolds number /cm: 26.3 < Re < 7522;Mach number: 0.8 < Mach < 20 France
In 1967, Congress granted approval for the construction of Tunnel 9. The facility became operational in 1976 and has since been providing aerodynamic simulation in critical altitude regimes associated with strategic offensive missile systems, advanced defensive interceptor systems, and hypersonic vehicle technologies.
The Triborough Bridge and Tunnel Authority (TBTA), doing business as MTA Bridges and Tunnels, is an affiliate agency of the Metropolitan Transportation Authority that operates seven toll bridges and two tunnels in New York City. The TBTA is the largest bridge and tunnel toll agency in the United States by traffic volume.
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
NASA Langley's Hypersonic Facilities Complex, 1969. A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow.
