ESTIMATION OF OPERATING CONDITIONS OF A MID-RANGE AIRCRAFT AUXILIARY POWER UNIT WITH RECEIVER INLET IN TURBULENT FLOW
SINOPSIS
A series of computational and experimental studies are performed in order to estimate the characteristics of the receiver air inlet of an advanced mid-range aircraft. The air inlet design includes two flaps deflected at an angle of 30°. The computational and experimental results are obtained for one of the most critical flight regimes at M = 0 (H = 0). The recently developed technique called EWT−TsAGI provides a high accuracy of the computational results for the model studies in spite of the flow separation near the components of the receiver air inlet. Good agreement of computational and experimental data is shown (the model scale is 1:6.5). Special attention is given to the characteristics of the air inlet in the case of the fail to open flaps and their damage. The flow parameters near the auxiliary power unit are analyzed in the cruise flight regime at M ≈ 0.8. An algorithm for estimating the total pressure loss at the inlet to the engine is developed.
