Classical aeroelastic scaling laws for fixed wing applications have been based on the concept of a typical cross section combined with Theodorsen-type frequency domain aerodynamics (Bisplinghoff et al., ).The geometry of this problem is illustrated in Fig. the last 50 years aeroelastically scaled wind tunnel models have been widely used in testing, and Cited by: The Langley Meter Transonic Cryogenic Tunnel is used for testing airfoil (wing) sections and other models at Reynolds numbers up to x 10 6 per foot and Mach numbers from to The adaptive walls, floor, and ceiling in the test section can be moved to eliminate or reduce effects of air around the model being artificially.

Title: A Century At Langley, Author: NASA Langley, Name: A Century At Langley, Length: pages, Page: 1, Published: Helicopter Rotor Testing. Electra model in the TDT . Techniques for the testing of model-scale rotors and helicopter airframes are well developed for performance and low-frequency stability phenomena. Wind tunnels adequate for foot model rotors are generally available for the achievable envelope of modern helicopters, including tunnels with moving ground planes to enhance their low-speed-in.

The AFW model, tested in the NASA TDT, was an aeroelastically scaled model of an advanced fighter jet with two leading-edge and two trailing-edge control surfaces per wing. The model was mounted on a sting mount, which allowed it to roll and pitch over a range of angles of attack. The model and its instrumentation are shown in Fig. Cited by: The two concepts were based on the double stack L-L concept developed by Lee and Chopra, and the double X-frame actuator by Hall et al. The double X-frame was finally selected for use in the smart material-actuated rotor technology (SMART) program which involved the hover and wind tunnel testing of the MD light utility helicopter rotor Cited by: 1.
