The invention aims to provide an aircraft S bend and embedded type combination air inlet channel. The combination air inlet channel comprises an actuating device, a sealing gasket, an air inlet channel jettison section, a breakable connecting device, an embedded type air inlet channel, an engine and an aircraft body. The air inlet channel jettison section is fixed on the outer portion of the aircraft body through the actuating device and the breakable connecting device and is in sealed butt joint combination with the embedded type air inlet channel through the sealing gasket on an air inlet channel jettison section flange to form an S bend air inlet channel. At a small flow starting period and a cruising period, an aircraft supplies gas to the engine through the S bend air inlet channel formed by combining the air inlet channel jettison section and the embedded type air inlet channel. When the aircraft is at a penetration period, the air inlet channel jettison section is discarded, and gas is supplied to the engine through the embedded type air inlet channel. The aircraft S bend and embedded type combination air inlet channel is simple in structure and convenient to use and has the advantages that the air inlet channel is good in reliability at the small flow starting period, high in total pressure recovery coefficient at the cruising period, good in stealth capability at the penetration period and high in battlefield survivability.
