The “strip-a-tubing” pressure belts are shown close-up on the right wing of NASA’s single-seat F-16XL (ship #1) used for the Cranked-Arrow Wing Aerodynamic Project (CAWAP) at Dryden Flight Research Center, Edwards, CA. The modified airplane features a delta “cranked-arrow” wing with strips of tubing along the leading edge to the trailing edge to sense static on the wing and obtain pressure distribution data.
The right wing receives data on pressure distribution and the left wing has three types of instrumentation – preston tubes to measure local skin friction, boundary layer rakes to measure boundary layer profiles (the layer where the air interacts with the surfaces of a moving aircraft), and hot films to determine boundary layer transition locations.March 8, 1995
