LARGE-SCALE WIND-TUNNEL TESTS OF INVERTING FLAPS ON A STOL UTILITY AIRCRAFT MODEL Terrell W. Feistel Ames Research Center and Joseph P. Morelli Aeromechanics Laboratory AVRADCOM Research and Technology Laboratories SUMMARY A unique inverting flap system has been investigated on a large-scale deflected slipstream.

LARGE-SCALE WIND-TUNNEL TESTS OF A DEFLEETED SLIPS= STOL MODEL WITH WINGS OF VARIOUS ASPECT RATIOS By V. Robert Page, Stanley 0. Dickinson, and Wallace H. Deckert Ames Research Center A wind-tunnel investigation was conducted to determine the longitudinal force characteristics of a large-scale model representative of a propeller- driven STOL Author: Kirtlano Afb, N Mex.

Full-scale testing in a wind tunnel is only possible with small aircraft - see the answers to this question for examples. Even then, the speeds do not match the top speed of the aircraft, so the loads are a fraction of the real loads.

Pitt, James P. Dunne, Edward V. White The Boeing Company. Wind tunnel experiments with scaled model turbines are a viable complement to field tests and simulations. The scaling of a 5 MW reference turbine with the aim of maintaining the design tip speed. The large size of commercial aircraft relative to existing icing wind tunnels and lack of robust scaling methods also makes ice accretion wind tunnel testing difficult.

Hybrid or truncated airfoil models use full-scale leading edges with redesigned aft sections to provide test articles with much reduced model chord and therefore tunnel blockage Cited by: 3. NASA recently tested a full-sized tail from a commercial aircraft that was modified and equipped with tiny jets called "sweeping jet actuators" to blow air across the rudder surfaces.

The “smaller” wind tunnel is a still-massive 40 feet by 80 feet, making it the second-largest wind tunnel in the world. The two wind tunnels were dedicated in As it’s able to accommodate planes with wing spans of up to feet, nearly all commercial aircraft made in the United States since have been tested in the subsonic tunnel.

The new 1" inside-diameter supersonic blow-down wind tunnel, having a test section blockage factor less than 3%, now joins the successful 1/2" supersonic wind tunnel.

However, the large scale of HPA made tests on a full model impossible during the project described. In the present work, wind tunnel tests are performed on a scaled wing. The primary objec-tive of this study is thus to observe experimen-tally the dominant properties of an aeroelastic high aspect ratio wing.

The forthcoming wind tunnel, simulator and flight tests will determine accurately what if any techniques can be used to recover from asymm settling.

It may be that only avoidance of entering the extreme rate of descent and application of violent control inputs that the NASA investigator saw evidence of on the CSMU could have saved the V crew.

A low-speed wind tunnel test was performed to investigate Reynolds number effects on the aerodynamic characteristics of a supersonic cruise wing concept model with a deg swept wing incorporating leading-edge and trailing-edge flap deflections.

The Reynolds number ranged from to x 10 to the 6th, and corresponding Mach numbers from Wind-tunnel tests and the results of departure criteria and linear analysis showed the destabilizing effect of the reduction of the vertical tail on the X Wind-tunnel testing also showed that differential canard deflection was capable of generating yawing moments of roughly the same magnitude as the thrust vectoring vanes currently in place.
