Low-speed wind tunnel circuits are designed as a group of standard segments connected in series with emphasis on drive power economy and flow quality in the test section. Methods for estimating circuit losses, expressed as an energy ratio, are given, along with design guidelines for diffusers, ...

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 streamline curvature equations represent a form of the exact, compressible, inviscid flow equations. The method is applicable from low subsonic to supersonic speeds. 关键词: Contraction cones - Ducts - Wind-tunnel design 被引量: 3 年份: 1973 ...
As a result, aeroelastic analyses become a more important part of the design of a new aircraft or an external store for an existing aircraft. Libo et al. [15] designed a wind tunnel test model for the flutter analysis. The model was used in a complete flutter certification procedure. GVT...
The design and test results of the new type high-subsonic speed submerged and semi-submerged intakes for cruise missile propelled by a turbojet engine have been introduced.───本文介绍了以涡轮喷气发动机为动力装置的飞航式战术导弹的一种新型高亚音速嵌入式、半嵌入式进气道的设计与试验研究结果。 I ha...
Two 1.64:1 scale models of a tandem cascade stator - the second model was a slightly changed version of the original design - were tested in a cascade wind tunnel for free stream Mach numbers of M = .5 to .9 and incidence angles of I = -4 deg. to +8 deg. Pressure measurements ...
This work is devoted to the study of the influence of the small angles of attack and external disturbances on the position of the laminar-turbulent transition in the supersonic boundary layer on swept wings. The experiments were carried out in a low-noise supersonic wind tunnel T-325 of the...
[From Stinton, D. (1983). “The Design of the Aeroplane,” Van Nostrand-Reinhold, Princeton, NJ.] Another area of focus is that of low-speed handling to reduce stall-spin accidents. Effort centers around the reduction of data obtained from wind tunnels, flight tests, and simulators. III...
Results show good agreement with experimental data within pre-stall, attached flow incidence range. This study demonstrates the conceptual and preliminary design power of applying the current Euler-Adjoint solver to a complex geometry at low Mach numbers. 展开 ...
