Embodiment Construction

[0056] The invention is described with respect to an aircraft including one or more main engines for moving the aircraft. The aircraft further comprises a passenger cabin which must be regulated for pressure and / or temperature. refer to figure 2 An apparatus 10 for providing non-propulsion power is described.

[0057] The device 10 for providing non-propulsion power comprises an Environmental Control System 1, known to those skilled in the art by the term ECS, and an Auxiliary Power Unit 4, known to those skilled in the art by the term APU. According to the invention, the ECS 1 and APU 4 are coupled such that the APU 4 provides power to the ECS unit 1 and thus reduces the take-off power obtained from the main engines of the aircraft.

[0058] ECS 1

[0059] like figure 2 As shown in , the ECS 1 includes a turbine 12 and a load compressor 11, the turbine 12 is used to transfer the conditioned air A reg Distributed into the aircraft nacelle 2 , the load compressor 11 is...

Abstract

The invention relates to a method for supplying non-propulsive power of an aircraft, comprising driving a shaft (13) of a system (1) for controlling the environment of the aircraft by a combination of energy sources selected from: an auxiliary power group (4); a starter / generator (18); and means (63) for supplying auxiliary air.

Description

technical field [0001] This invention relates to the field of providing non-propulsion power to aircraft, including the generation of electrical and aerodynamic power, to provide pressurization and air conditioning in the cabin for passengers in the aircraft. The temperature and pressure regulation of the passenger cabin is usually achieved using systems known to those skilled in the art, such as ECS, which stands for "environmental control system". When the main engines of the aircraft are deactivated, the supply of aerodynamic and / or electrical power is provided by an auxiliary power unit known to those skilled in the art, such as an APU standing for "auxiliary power unit". Background technique [0002] In simplified form, refer to Figure 1A , ECS 1 can transfer the ambient airflow A with external pressure P0 and external temperature T0 amb Transported to the aircraft to cool or heat the ambient air flow before it is distributed to the passenger cabin 2 . In fact, refer...
