Title:
空気サイクル装置パックシステム及び低い入口圧力での冷却性能を改善するための方法
Document Type and Number:
Japanese Patent JP6518423
Kind Code:
B2
Abstract:
An air cycle machine (ACM) pack system (10) for an aircraft (12) with an improved low inlet pressure cooling performance is provided. The ACM pack system (10) has an air cycle machine (ACM 42) with at least one compressor (72) mechanically coupled to at least one turbine (74) in series on an ACM shaft (78). The ACM pack system (10) further has a pack heat exchanger (44) coupled to and in fluid communication with the at least one compressor (72) of the ACM (42). The ACM system further has a bypass air flow assembly (11) coupled in a parallel operation path to the ACM (42) and has a bypass air flow regulating element (86). The bypass air flow assembly (11) transfers energy extracted by the bypass air flow assembly (11) to the ACM (42) to aid the ACM pack system (10) in cooling performance at a low inlet pressure, resulting in an improved low inlet pressure cooling performance of the ACM pack system (10).
