Abstract
Description
主な利益は、単なる計量バルブ位置の制御ではなく、供給燃料質量流量の閉ループ制御を行うことである。
従来のシステムに用いられている多数の構成部品が、統合されるか、あるいは取り除かれる。たとえば、従来の燃料制御装置の構成から、バイパス弁、水頭レギュレータ、およびロジック選択弁機能が取り外される。システムの主要部、サーボ部、および統合駆動式発電機(IDG)部の熱交換器3基が、ただ1つのユニットに統合される。
構成部品の数や、システム全体の複雑さを増すことなく、燃料供給の大きな改良が達成される。
本発明のさらに別の長所と利点は、以下の詳細な説明を読み理解することにより、当業者にとって明らかになろう。
