To provide an internal combustion engine for an aircraft which enables improvement of a fuel consumption rate.SOLUTION: An internal combustion engine for an aircraft includes: a gas turbine 2; a lubrication oil supply pipe 31 in which a lubrication oil circulates; a variable capacity electric pump 33 which supplies the lubrication oil to the gas turbine 2; a temperature detection unit 5 which detects a temperature of the lubrication oil; a supply amount detection unit 6 which detects a supply amount of the lubrication oil; a rotation number detection unit 4 which detects a rotation number of the gas turbine 2; and a control unit 7. The control unit 7 sets a target supply amount of the lubrication oil based on the rotation number of the gas turbine 2 detected by the rotation number detection unit 4 and the temperature of the lubrication oil detected by the temperature detection unit 5 and controls a discharge amount of the lubrication oil so that the supply amount of the lubrication oil detected by the supply amount detection unit 6 matches with the target supply amount.SELECTED DRAWING: Figure 2
【課題】燃料消費率を向上することができる航空機用の内燃機関を提供する。【解決手段】ガスタービン2と、潤滑油が流通する潤滑油供給管31と、ガスタービン2に潤滑油を供給する可変容量型の電動ポンプ33と、潤滑油の温度を検出する温度検出部5と、潤滑油の供給量を検出する供給量検出部6と、ガスタービン2の回転数を検出する回転数検出部4と、制御部7と、を備える。制御部7は、回転数検出部4により検出されるガスタービン2の回転数及び温度検出部5により検出される潤滑油の温度に基づいて潤滑油の目標供給量を設定し、供給量検出部6により検出される潤滑油の供給量が目標供給量と一致するように、潤滑油の吐出量を制御する。【選択図】図2
