Power to Lift

Large-scale powered-lift demonstrations underline the value of flow control for aircraft efficiency

During the past year, two large powered-lift models have been tested in the National Full-Scale Aerodynamics Complex (NFAC) at NASA Ames Research Center in California, evaluating the low-speed benefits of blowing air over high-lift flaps for short takeoff and landing (STOL).

High-speed tests in the National Transonic Facility (NTF) at NASA Langley Research Center in Virginia have investigated the benefits of blowing to reduce drag in the cruise. And while a STOL transport, civil or military, looks unlikely in the next decade or so, the wind-tunnel tests conducted
