概述
輔助動力裝置APU 是一個獨立的完整的裝置它使飛機的工作不依賴外部氣源和電源
在地面
- 為起動發(fā)動機和空調(diào)系統(tǒng)提供引氣
- 給電氣系統(tǒng)提供電源
起飛過程中
- 當(dāng)飛機需要最佳性能時由APU 完成空調(diào)供氣工作這樣避免了由于使用發(fā)動機引氣而造
成的發(fā)動機推力減小
在飛行中
- 為電氣系統(tǒng)提供備份
- 為空調(diào)系統(tǒng)提供備份
- 可用于發(fā)動機起動
APU 起動電源可從飛機電瓶或正常電氣系統(tǒng)或地面勤務(wù)匯流條獲得
在正常飛行包線范圍內(nèi)APU 都可起動參見FCOM 3.01.49
ECAM 上顯示APU 參數(shù)
