低速风洞全模TPS试验空气桥的设计与优化
Design and optimization of the air bridge for low speed full-span TPS test
摘要
Abstract
TPS(Turbofan Powered Simulator)technology is the most advanced engine simulation in wind tunnel test. The air bridge is a key technology of TPS tests. This paper presents the design of the air bridge for low speed full-span TPS test. Optimum designs are made for the key beams of the air bridge by using FEM (finite-element method). Layout and the dimension of bellows are also optimized. According to the computation results, the key law of air bridge design is concluded. The air bridge is finally designed according to the space of the model, the inside e-quipments and the requirement of the TPS test. The final design has little effect on force measurement and has little pressure and temperature effect. The success in low speed full-span TPS test indicates that the air bridge meet the requirement of TPS test.关键词
