wind tunnelfree jetsubsonicblow downThis paper presents the design and analysis of a free jet, blow down subsonic wind tunnel for acoustic measurement. The wind tunnel is made from the artificial fibre which is optimized for achieving subsonic i.e., 0.3 ≤ M ≤ 0.8 steady flow (low ...
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-...
Wind-Tunnel Experiments on the Flow over Rectangular Cavities at Subsonic and Transonic Speeds Measurements have been made of the time average and unsteady pressures acting on the roof and behind a series of rectangular cavities set in the roof of the 2 ft x 1tr ft transonic tunnel.It was ...
Wind-Tunnel Experiments on the Flow over Rectangular Cavities at Subsonic and Transonic SpeedsA general theory of three-dimensional flow in subsonic and supersonic turbomachines of axial-, radial-, and mixed-flow typesA doublet-lattice method for calculating lift distributions on oscillating surfaces ...
The aerodynamic design of a wind-tunnel model of a wing representative of that of a subsonic jet transport aircraft, fitted with winglets, was performed using two recently developed optimal wing-design computer programs. Both potential flow codes use a vortex lattice representation of the near-field...

This means, that two types of patches may be present: 'design patches', whose surface is derived from given pressures and 'analysis patches', whose pressures are derived from given surface. To solve such 'mixed' problems the panel code is embedded into an iteration loop, which minimizes the...
It's capable of subsonic flying as high as 12 thousand meters with an attack range of at least 2000 kilometers. 它的次音速飞行能力高达1.2万米,攻击距离至少为直径2000公里。 youdao The design and test results of the new type high-subsonic speed submerged and semi-submerged intakes for cruise...
