    • A system and method for improved efficiency of an integrated power and cooling unit, IPCU (100), of an aircraft is disclosed. The IPCU (100) comprises a compressor (104), a starter/generator (106) and at least a cooling turbine (102), all coupled to a common shaft (110). The system (300) uses an open-loop cooling system and turbo machine power-matching to provide wide operation range without over-sizing. In order to reduce the temperature of the air flow through a cooling heat exchanger (116), the cooling turbine (102) needs to expand further, at the same time generating power to the shaft (110). To avoid the power being higher than the compressor (104) could absorb, the starter/generator (106) is used to convert the power into electrical power supplied to loads on the aircraft, to arrive at a more efficient system. Power sum control (302,304) via distribution control units is used to couple a bus (115) receiving power from the IPCU (100) starter/generator (106), with buses (128,132) receiving power from generators (124,126) of the aircraft engine (122).
    • 公开了一种用于提高飞机综合功率和冷却​​单元(IPCU(100))效率的系统和方法。 IPCU(100)包括压缩机(104),起动器/发电机(106)和至少一个冷却涡轮机(102),其全部联接到公共轴(110)。 系统(300)使用开环冷却系统和涡轮机功率匹配来提供广泛的操作范围,而不会过大。 为了降低通过冷却热交换器(116)的空气流的温度,冷却涡轮(102)需要进一步膨胀,同时向轴(110)产生动力。 为了避免功率高于压缩机(104)吸收的功率,起动器/发电机(106)用于将功率转换成供应给飞机上的负载的电力,以获得更有效的系统。 通过分配控制单元的功率和控制(302,304)用于将从IPCU(100)启动器/发电机(106)接收电力的总线(115)与从飞行器引擎的发电机(124,126)接收功率的总线(128,132) (122)。
