An aircraft comprising a main engine to provide a supply of bleed air, an APU housing within an APU compartment and having an APU bleed valve, an APU bleed air duct connecting main engine with the APU, and a bleed air heating system for the APU compartment comprising an auxiliary pipeline connecting the APU bleed air duct with the APU compartment, a temperature sensor, an auxiliary pipeline valve to control the discharge of bleed air into the APU compartment, and a temperature controller configured to establish a heating operation mode, when the sensed temperature falls below a minimum temperature threshold value, and a standby operation mode, when the sensed temperature surpasses a maximum temperature threshold value. The temperature controller operates the main engine and the valves to establish these operation modes.

Aircraft with a bleed air heating system for APU compartment

An Auxiliary Power Unit ('APU') for an aircraft with reduced weight, but which at the same time meets all fire-related airworthiness standards. The APU comprises a metallic housing having mounts for attaching the housing to an external structure. The APU further comprises at least one temperature sensor suitable for detecting temperature under fire conditions. The temperature sensor is coupled with the mounts for sensing temperature at the housing.
