An air intake system of an aircraft is improved so that a performance of the air intake system will not be degraded even during flight at a large angle of attack and at high mobility of the aircraft while at the same time secretiveness or security of the aircraft against radar beam irradiation from below will be maintained. The air intake system includes a main air intake port provided on an upper surface of the airframe of the aircraft, an auxiliary air intake port provided on a lower surface of the airframe, and a closure member for the auxiliary air intake port and which is movable between a closed position and an open position of the auxiliary air intake port.
