What are the 2 main types of wind tunnel?
Wind Tunnel Test There are basically two types of wind tunnel test which are static stability and the pressure test. With these two tests, you can determine the aerodynamic characteristics of the aircraft.
What are the different types of wind tunnels?
Wind tunnels are classified as low-speed or high-speed; they are further classified as subsonic (80 percent of the speed of sound), transonic (about the speed of sound), supersonic (up to 6 times the speed of sound), hypersonic (6 to 12 times the speed of sound), and hypervelocity (over 12 times the speed of sound).
Where is the largest wind tunnel?
NASA’s Ames Research Center
The largest wind tunnel in the world is at NASA’s Ames Research Center. This subsonic tunnel, which can test planes with wing spans of up to 100 feet, is over 1,400 feet long and 180 feet high.
What are the five parts of a wind tunnel?
Finally, you should know the five basic parts of the wind tunnel. From front to back, they are: The Settling Chamber, the Contraction Cone, the Test Section, the Diffuser, and the Drive Section.
What is a closed wind tunnel?
Wind tunnels are designed for a specific purpose and speed range. Therefore, there are many different types of wind tunnels and several different ways to classify wind tunnels. In the closed return tunnel, air is conducted from the exit of the test section back to the fan by a series of turning vanes.
What is a supersonic wind tunnel used for?
A suction type continuous operation supersonic (up to Mach 1.8) wind tunnel for investigations into subsonic and supersonic air flow around two dimensional models.
What are the parts of a wind tunnel?
The wind tunnel is comprised of five main parts, listed in order from front to back: the settling chamber, the contraction cone, the test bed, the diffuser, and the fan housing with a variable speed motor.
What is a low speed wind tunnel?
Low Speed Wind Tunnel. The low speed wind tunnel is a closed-circuit, continuous flow type with a 100 horsepower variable frequency drive. The test section flow area is 0.6 x 0.9 meters (2 x 3 feet).
What is an open jet wind tunnel?
The Open-Jet Wind Tunnel (OJWT) is an open section, closed circuit tunnel, designed, built and commissioned by the Aeromechanical Systems Group. The Aeromechanical Systems Group is a research group based at the Defence Academy of the UK in Shrivenham, with diverse expertise in both aeronautical and power systems.
What is wind tunnel testing?
Wind Tunnel Testing. Overview. Wind–tunnel testing is an integral part of the design process in many industries, typically used to verify and tune the aerodynamic properties of solid objects. Whether an object is stationary or mobile, wind tunnels provide insight into the effects of air as it moves over or around the test model.
