Effect of Wedge-Shaped Deflectors on Flow Fields of Dual-Stream Jets [PDF]

, 2007
The effect of wedge-shaped fan flow deflectors on the mean and turbulent flow-fields of dual-stream jets is investigated. Several wedge-shaped deflector concepts were used to create asymmetry in the plume of a dual-stream jet issuing from a scaled down ...

Selection of parameters for design of engine, turbofan and turbocompressor consisting of turbofan and turbofan mixed flow

Perm National Research Polytechnic University Aerospace Engineering Bulletin
The article considers the features of the selection of the main parameters in the design of turbofan and turbofan-type turbofans, turbofans and turbocompressors of the gas generator in their composition. In addition to the known methods, new methods are proposed for using generalized statistical dependencies, such as the ratio of the diametrical ...
