The 131-9 Auxiliary Power Unit (APU) introduced a two-stage axial turbine for longer engine life and a single starter/generator that uses electrical power to start the APU, and then becomes a generator once it’s running.

Honeywell auxiliary power units are a series of gas turbine auxiliary power units (APU) made by Honeywell Aerospace. Honeywell started manufacturing APUs in the early 1950s and since then they can be found on many aircraft. [1] Over the years Honeywell have produced more than 95,000 APUs and more than 36,000 are still in service. [2]

专为波音MD-90飞机设计的131-9D辅助动力装置 (APU) ，并成为波音B737NG系列飞机的标配，空客A320机型的客户也可选装。 庞巴迪C系列飞机也选用了该系列辅助动力装置。 该系列辅助动力装置广受欢迎的原因显而易见，其中之一就是其采用了两级轴流式涡轮设计以延长发动机寿命，同时通过起动/发电系统用电能启动APU，并在APU运行时转换为发电机模式为飞机供电。 到目前为止， 131系列APU已 拥有超过1亿小时的安全运行时间，是霍尼韦尔有史以来最成功的辅助动 …

131-9A AUXILIARY POWER UNIT HIGH- EFFICIENCY MODE Airbus narrowbody operators flying with Honeywell’s 131-9A APU can save up to $11,000 in annual fuel costs and improve on-wing-time by as much as 17% with the new High Efficiency Mode (HEM) upgrade. These and other benefits are available to operators who install an improved

GTCP131-9[A]型APU是恒速涡轮喷气发动机，其工艺设计特点是坚固、经济耐用。该APU已通过FAA及欧洲权威机构评定为1类APU。在正常飞行情况下，APU是非必要设备。但根据MEL（minimumequipmentlist），在一定条件下，APU是必需的设备。
