Wind tunnels have a variety of important uses in the world today. Wind tunnel that used here is an open loop low speed wind tunnel. The fundamental principles of this tunnel is moving the air using exhaust fan in the rear side, and placing the cube in the external balance system which ...
An experimental investigation of the M85, a High Speed Rotor Concept, was conducted at the NASA Langley 14 x 22 foot Subsonic Tunnel, assisted by NASA-Ames. An unpowered 1/5 scale model of the XH-59A helicopter fuselage with a large circular hub fairing, two rotor blades, and a shaft ...
This movie presents a full set of images from a wind tunnel test combined in an animation. In the test, the 65° delta wing model of 420 mm length and 332 mm span was tested in subsonic wind tunnel at constant flow speed of 50 m/s and varying the angle of attack...
Low-speed wind tunnel tests were conducted to determine the subsonic aerodynamic characteristics of an optimized supersonic (Mach 6) conical-flow waverider designed for a deck-launched intercept mission. These tests are part of the continuing waverider research being conducted by the Naval Postgraduat...
摘要: The goal of wind tunnel design is to generate a uniform air flow with minimum turbulence intensity and low flow angle. The nozzle is the main component of wind tunnels to create a ... 查看全部>>关键词: Subsonic wind tunnel Nozzle Contraction ratio Adverse pressure gradient Flow non-...
The experimental data from 14 × 22 foot subsonic wind tunnel, Langley, National Aeronautics and Space Administration (NASA) are adopted for comparison.19 The freestream condition is Ma = 0.2, Re = 4.5 × 106 and α = 28°. A structured patch grid (point to point) with 14.65 million ...
A subsonic wind tunnel has been designed and built with two honeycomb screens and a contraction cone with a contraction ratio (CR = 8) to achieve a flow speed of 30 m/s in the test section and can be used for various aerodynamics research projects [14]. The old design contraction for ...
All of the models for tandem wing configurations were conducted in the low turbulence wind tunnel (LTWT) located in the Northwestern Polytechnical University (NPU) in Xi’an, China. This wind tunnel is an open circuit low speed, low turbulence wind tunnel with a working section that is 1200 ...
