Adaptive Airfoils for Drag Reduction at Transonic Speeds
Adaptive airfoils and wings can provide superior performance at the expense of increased cost and complexity. In this paper, an aerodynamic optimization algorithm is used to assess an adaptive airfoil concept for drag reduction at transonic speeds. The objective is to quantify both the improvements in drag that can be achieved and the magnitude of the shape changes needed. In an initial study, ...
متن کاملThePressure-Drag due to Blunt Leading Edges on Two-Dimensional Aerofoils, at Transonic and Low-Supersonic Speeds
Pressure drags, obtained from measured pressure distributions in the transonic and low-supersonic speed range, are compared for sharp and blunt leading-edged two-dimensional aerofoils. For the special blunt shapes considered here, the high pressures in the stagnation-point region are offset by low pressures generated further round on the leading edge and on the basic aerofoil itself. The result...
متن کاملTurbulent Drag Reduction by Spanwise Wall Oscillations
The objective of this paper is to examine the effectiveness of wall oscillation as a control scheme of drag reduction. Two flow configurations are considered: constant flow rate and constant mean pressure gradient. The Navier-Stokes equations are solved using Fourier-Chebyshev spectral methods and the oscillation in sinusoidal form is enforced on the walls through boundary conditions for the sp...
متن کاملAfterbody Drag Measurement at Transonic Speeds on a Series of Twin and Single Jet Afterbodies Terminating ct the Jet-Exit
SUMMARY A systematic sex-188 of twin-jet afterbodaes all terminating at the jet-exit has been tested at Mach numbers from M = 0.7 to 1.3 on a strut-mounted rig employing high pressure air for the Jet streams. The afterbody drag was derived from balance measurements of thrust-minus-drag and wind-off calibrations of thrust, and interpreted with the help of pressure plotting data. Two single-nozzl...
متن کاملFluid Structure Interaction on AGARD 445.6 wing at Transonic Speeds
Aircraft is a complex structure, but a very efficient man made fly ing machine. An aircraft is a machine that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. It counters the force of grav ity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet. In this project the flu id–structure inte...
