Abstract
【解決手段】環境制御システム6のための圧縮機ブリード空気38を冷却する予冷器7は、冷却空気57の供給源と流体連通し且つ圧縮機ブリード空気38を冷却する空気間熱交換器56を含む。ブリード空気供給源と環境制御システムとの間の可変バイパスバルブ74は、熱交換器の周りに圧縮機ブリード空気をバイパスする。冷却空気は、可変ファン空気バルブ76によって調整されるファン空気33の一部とすることができる。ブリード空気供給源は、低圧ブリード空気供給源と高圧ブリード空気供給源118との間で選択可能とすることができる。方法は、低圧供給源からのみの圧縮機ブリード空気を流すステップと航空機の進入又はロイター中に1エンジン停止状態時にブリード空気の最小レベルの圧力に適合するよう推力レベルを増大させるステップとを含む。
