Wind Tunnels

Some articles on wind tunnels, wind tunnel, tunnel, tunnels:

Ames Research Center - Wind Tunnels - National Full-Scale Aerodynamics Complex (NFAC)
... Ames Research Center also houses the world's largest wind tunnel, part of the National Full-Scale Aerodynamic Complex (NFAC) it is large enough to test full-sized planes ... The 40 by 80 foot wind tunnel circuit was originally constructed in the 1940s and is now capable of providing test velocites up to 300 knots (560 km/h 350 mph) ... The 40 by 80 Foot Wind Tunnel is primarily used for determining the low- and medium-speed aerodynamic characteristics of high-performance aircraft, rotorcraft, and fixed wing, powered-lift V/STOL aircraft ...
Water Tunnel (hydrodynamic)
... A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water ... It is very similar to a recirculating wind tunnel but with water as the working fluid, and related phenomena are investigated, such as measuring the forces ... Water tunnels are sometimes used in place of wind tunnels to perform measurements because techniques like particle image velocimetry (PIV) are easier to ...
Wind Tunnel - History - Post World War Two
... Computational fluid dynamics (CFD) can increase or possibly replace the use of wind tunnels ... For example, the experimental rocket plane SpaceShipOne was designed without any use of wind tunnels ... were attached to the surface of the wings, performing a wind tunnel type of test during an actual flight in order to refine the computational model ...
Supersonic Wind Tunnel - Power Requirements
... The power required to run a supersonic wind tunnel is enormous, of the order of 50 MW per square meter of test section cross-sectional area ... For this reason most wind tunnels operate intermittently using energy stored in high-pressure tanks ... These wind tunnels are also called intermittent supersonic blowdown wind tunnels (of which a schematic preview is given below) ...

Famous quotes containing the word wind:

    The wind sprang up at four o’clock
    The wind sprang up and broke the bells
    Swinging between life and death
