Focke's wind tunnel is a fully operational wind tunnel in the former private laboratory of the aviation pioneer Henrich Focke (1890–1979), co-founder of Focke-Wulf and designer of the first fully controllable helicopter, the Focke-Wulf Fw 61. Henrich Focke built the laboratory in 1960 at the age of 70 in the city of Bremen. Until shortly ...
The airframe was then converted into a wind tunnel testbed, which was tested in the NASA Ames Research Center 40x80 feet full-scale wind tunnel in 1979. [4] A second airframe was completed (73-21942) which first flew on July 21, 1975. After initial testing as a pure helicopter, two auxiliary turbojets were added in March 1977.
In September 1969, Cheyenne prototype #10 (s/n 66-8835) underwent wind tunnel testing at NASA Ames Research Center, to research the half-P hop and drag issues. The engineers did not realize that the fixed mounts used to secure the aircraft in the wind tunnel would not allow the helicopter to move relative to the rotor, as it did in flight.
Cessna pilots test flew Seibel's S-4B for several months to familiarize the engineers with helicopters, and then it was scrapped. [2] A quarter-size wind tunnel model of the CH-1 was created and tests were conducted at Wichita State University. The first full-size machine did not have an enclosed fuselage or cowling, nor a horizontal stabilizer.
He adapted computer simulation models designed for helicopters to study wind turbines. [2] Doman and his team then built scale-model wind turbines to test them in a wind tunnel normally used for helicopters and airplanes. [2] Doman soon understood the similarities and key differences between wind turbines and helicopters. [2]
Wind tunnel model. The Belvedere was based on the Bristol Type 173 10-seat (later 16-seat) civilian helicopter which first flew on 3 January 1952. The 173 project was cancelled in 1956, and Bristol spent time on the Type 191 and Type 193 to Royal Navy and Royal Canadian Navy specifications.
The test activities performed include component-level development and qualification icing wind tunnel testing at Cox & Co in Long Island, NY, icing qualification testing of the engine air intake ice protection system at Rail Tec Arsenal in Vienna, Austria, artificial icing flight testing using the US Army Helicopter Icing Spray System (HISS ...
A one-fifth-scale wind tunnel model has undergone testing in the Transonic Dynamics Tunnel (a unique transonic wind tunnel) at NASA's Langley Research Center during summer 2006. The "semi-span" model (representing the starboard half of the aircraft) measured 213 inches in length and had powered 91-inch rotors, operational nacelles, and ...
