To freely perform both of reduction of a pressure resistance and reduction of friction resistance, and perform air flow control therefor in a state of having no penalty substantially.SOLUTION: An air flow controller 4 comprises: a sensor 5 for detecting a state of a boundary layer on a machine body surface; a removal prevention device 7 which is arranged on the machine body surface, which is operated by high pressure gas, which applies a momentum to the boundary layer for controlling removal; a blowing device 8 which is arranged on the machine body surface, which blows the high pressure gas equally for reducing a turbulent flow frictional resistance; and a control system 9 for, according to a detection result by the sensor 5, switching between supply of the high pressure gas to the removal prevention device 7 and the supply of the high pressure gas to the blowing device 8.SELECTED DRAWING: Figure 3
【課題】圧力抵抗低減と摩擦抵抗低減の両方を自在に行うこと、そのための気流制御を実質的にペナルティレスで行うこと。【解決手段】気流制御装置4は、機体表面上の境界層の状態を検知するセンサ5と、機体表面に配置され、高圧の気体によって動作し、境界層に運動量を与えることによって剥離を制御する剥離防止デバイス7と、機体表面に配置され、高圧の気体を一様に吹き出すことによって乱流摩擦抵抗を低減する吹き出すデバイス8と、センサ5による検知結果に応じて、高圧の気体を剥離防止デバイス7に供給するか、吹き出しデバイス8に供給するかを切り替えるコントロールシステム9とを有する。【選択図】図3
