News dated
On 2 October, NASA described a test in the Transonic Dynamics Tunnel at Langley, Virginia. A wing model was coated in pressure-sensitive paint: under ultraviolet light, its brightness changes with air pressure. High-speed cameras record the variations. [1]
The model helps compare measurements and simulations without representing a particular aircraft. NASA says this was the technique’s first use on a large, freely moving model in a low-oxygen environment. Future tests on flexible wings remain the next step. [1]
The bright side
The test expands the tools available to improve aircraft simulations; it does not yet demonstrate fuel savings in flight. [1]
One idea, in simple words
How can you tell where air pushes on a wing? NASA used a special paint. Under ultraviolet light, its brightness changes with pressure: the air pushing against the surface. Very fast cameras record these changes. Computers can turn them into numbers for researchers to study. It is like making a pressure map, rather than just looking at the shape of the wing. [2]
The 2 October news describes a ground test inside a wind tunnel in Virginia. The model could move and did not represent a particular aircraft. The data help check computer simulations. This is not yet proof that an aircraft uses less fuel. Further tests will study models of flexible wings. [1]
