To make it possible to reduce weight of a storage battery.SOLUTION: In a propulsion system for an aircraft, when a flight state of the aircraft is a first state in which the aircraft is cruising, power is supplied to an electric motor only by a capacity type storage battery. When the flight state of the aircraft is a second state in which the aircraft is taking off or landing, power is supplied to the electric motor only by an output type storage battery if the amount of charge of the output type storage battery is equal to or greater than a first threshold, and power is supplied to the electric motor by the output type storage battery and the capacity type storage battery if the amount of charge of the output type storage battery is less than the first threshold.SELECTED DRAWING: Figure 5 【課題】蓄電池の重量を削減することができる。【解決手段】航空機用推進システムは、航空機の飛行状態が、航空機が巡航中である第１状態である場合、容量型蓄電池のみにより電動機に電力を供給し、航空機の飛行状態が、航空機が離陸中であるまたは着陸中である第２状態である場合、出力型蓄電池の充電量が第１閾値以上である場合は出力型蓄電池のみにより電動機に電力を供給し、出力型蓄電池の充電量が第１閾値未満である場合は出力型蓄電池及び容量型蓄電池により電動機に電力を供給する。【選択図】図５
