The numerical method is implicit approximate factorization developed by Beam and Warming. The calculation model is UDF style engine with 8 by 8 SR-3 propellers. The distribution of pressure on the blade surfaces, the propeller efficiencies, and the velocity vectors downstream of propellers are obtained. The relation of propeller efficiencies and velocity vectors downstream of rear propellers shows the features of counter-rotating propellers., 資料番号: NALSP0009036, レポート番号: NAL SP-9}, title = {ATPエンジンまわりの流れの数値シミュレーション}, year = {1988} }
