Provided is an aircraft internal combustion engine capable of improving a fuel consumption rate. An aircraft internal combustion engine (1) includes a gas turbine (2), a lubricating oil supply pipe (31) through which a lubricating oil flows, a variable capacity type electric pump (33) that supplies the lubricating oil to the gas turbine (2), a temperature detection unit (5) that detects the temperature of the lubricating oil, a supply amount detection unit (6) that detects a supply amount of the lubricating oil, a rotation speed detection unit (4) that detects a rotation speed of the gas turbine (2), and a control unit (7). The control unit (7) sets a target supply amount of the lubricating oil based on the rotation speed of the gas turbine (2) detected by the rotation speed detection unit (4) and the temperature of the lubricating oil detected by the temperature detection unit (5), and controls a discharge amount of the lubricating oil such that the supply amount of the lubricating oil detected by the supply amount detection unit (6) matches the target supply amount.
