Abstract
The paper introduced established inlet and jet test techniques for large scale model in the 8 m×6 m Low Speed Wind Tunnel with a vacuum pumper and a jet simulator.The single vacuum pumper can attain suction flux to 383 m3/min which fulfills 100% flux demand for large scale fighter plane model in the 8 m×6 m test section.The maximal exit pressure ratio of the jet simulator reaches to 3.5.Through increasing the ratio of the model compared with that in a wind tunnel of 3 m magnitude,the test can simulate aerodynamic configuration with increasing details, and the test can more precisely provide inlet performance,influence of the jet on a fighter plane, and the parameter of vectoring nozzle.关键词
