What does W/T mean in NASA
Wind tunnel is an experimental tool used to study the effects of air or other gases on the aerodynamic performance of objects in motion. It's a device that allows researchers and engineers to simulate various aerodynamic conditions, analyse the behaviour of objects in a controlled environment, and create design solutions to improve their performance. It enables us to observe how fluid flows around a model aircraft, car or other object in motion and can provide valuable insight into airflow patterns, lift, drag and other aerodynamics factors that are required for successful flight or efficient transportation.

Explanation
A wind tunnel is basically a large tube with fans at one end used to generate air flow. This air flow can be adjusted in terms of its velocity and direction depending on the model being tested. Depending on the size of the tunnel, larger models can be studied over longer periods of time due to its low turbulence which makes it ideal for conducting experiments over long periods of time without disturbing results. The walls are constructed from either metal or glass so that the airflow pattern can be observed from outside the tunnel. A variety of instruments such as force transducers or pressure-sensitive paint are used to measure forces acting on a model during testing.
Essential Questions and Answers on Wind Tunnel in "GOVERNMENTAL»NASA"
What is Wind Tunnel?
Wind tunnel is a facility in which airflow around objects can be studied. It consists of a wind tunnel with a test section in which the object to be studied is placed. The air flow through the test section can be regulated, measured and visualized in order to understand the aerodynamics of the object that is being tested.
What are some applications of Wind Tunnels?
Wind tunnels are used to study aircrafts, automobiles, buildings, bridges and other structures by testing their aerodynamic properties. They can also be used for research into fluid dynamics or for industrial processes such as cooling fans or turbines.
What are the different types of wind tunnels?
There are two main categories of wind tunnels - open-return tunnels and closed-return tunnels. Open-return tunnels contain an opening at one end of its test section allowing air to enter and exit while closed-return tunnels keep the air inside its confines and circulate it internally. Open-return tunnels are typically used for subsonic speeds (less than Mach 1) while closed-return tunnels can simulate supersonic speeds (greater than Mach 1).
How is air speed generated in a wind tunnel?
Airspeed in a wind tunnel is generated either by driving multiple blower fans or by using a single large fan powered by an engine or motor. The fans create an airstream flowing over the model under test, creating pressure differences across it that can be measured, recorded and analyzed.
Can wind tunnels simulate real world conditions?
Yes, wind tunnels have been designed to simulate real world conditions such as natural winds on structures or airflow past vehicles moving at high speeds on highways. Special features such as boundary layer control systems and gust generators allow engineers to recreate more realistic airflow patterns during testing.
How do you measure air velocity inside a wind tunnel?
Inside a wind tunnel, air velocity is usually measured using hot wire probes that hitch onto fast response thermocouples connected to sensitive electronic equipment capable of detecting even slight changes in temperature. Other methods such as laser Doppler velocimetry (LDV) use laser beams which measure fluctuations in speed of light caused by movement of particles in the surrounding airflow.
What parameters can be determined from wind tunnel testing?
Wind tunnel testing allows engineers to gain insights into several parameters such as lift coefficient (lift divided by dynamic pressure multiplied by reference area), drag coefficient (drag divided by dynamic pressure multiplied by reference area), angle of attack (angle between chord line and free stream direction) etc., as well as determining forces acting on the model.
Are there any safety features built into modern day wind tunnels?
Yes, modern day wind tunnels typically feature viewing ports made from shatterproof material like polycarbonate glass along its walls so operators can safely observe tests without being exposed to high pressures directly. They often come with additional safety devices such as circuit breakers which will shut down operations if excessive pressure levels occur inside.
Final Words:
Wind tunnels provide scientists and engineers with invaluable data for creating better designs for aircrafts, cars and other objects in motion. They allow us to gain deeper understanding about how different forces interact when something moves through air as well as analyze how a particular design performs under certain conditions. With this knowledge researchers have been able to develop more efficient design solutions while engineers have been able to validate their designs more accurately before they reach production stages. Wind tunnels have become an invaluable tool in the aerospace industry so much so that they are now considered an indispensable part of any research laboratory around the world!
