Zusammenfassung: | To control a temperature of a battery to a temperature suitable for charging.SOLUTION: A propulsion system includes a gas turbine mounted on an air craft, a power generator connected to the gas turbine, a battery for storing power generated by the power generator, a motor driven by the power from the power generator and/or the power from the battery, a rotor driven by the motor, a first flow channel for circulating first fluid discharged from the gas turbine, a second flow channel for circulating second fluid circulating in the vicinity of the battery, a heat exchanger for performing heat exchange between the first fluid circulating through the first flow channel and the second fluid circulating through the second flow channel, a control device for controlling opening/closing of a flow channel opening/closing valve provided in the first flow channel, and temperature detection means for detecting a temperature of the battery, in which when the temperature detected by the temperature detection means is equal to or lower than a first temperature, the control device opens the flow channel opening/closing valve, and thereby circulates the first fluid through the heat exchanger, and heats the battery.SELECTED DRAWING: Figure 1
【課題】バッテリの温度を充電に好適な温度に制御すること。【解決手段】推進システムは、航空機に取付けられるガスタービンと、ガスタービンに接続された発電機と、発電機が発電した電力を蓄えるバッテリと、発電機からの電力および/又はバッテリからの電力により駆動されるモータと、モータによって駆動されるロータと、ガスタービンから排出される第1流体を流通させる第1流路と、バッテリの付近を流通する第2流体を循環させる第2流路と、第1流路を流通する第1流体と第2流路を流通する第2流体との間で熱交換を行わせる熱交換器と、第1流路内に設けられた流路開閉弁の開閉を制御する制御装置と、バッテリの温度を検出する温度検出手段と、を備え、制御装置は、温度検出手段が検出した温度が第1温度以下である場合、流路開閉弁を開弁させることにより、第1流体を熱交換器に流通させてバッテリを加温する。【選択図】図1 |
