Abstract

The invention discloses an aircraft ground ventilation cooling method and device. The aircraft ground ventilation cooling device is adopted to forcibly blow strong cold air into an air inlet of an airborne equipment compartment and an air inlet of an engine compartment of an aircraft, and the strong cold air passes through the interiors of the airborne equipment compartment and the engine compartment to blow hot air in the airborne equipment compartment and engine compartment of the aircraft out of the compartments to fulfill the aim of ventilation cooling. According to the method and the device, the strong cold air can be provided for the airborne equipment compartment and engine compartment of the aircraft to cool the airborne equipment compartment and the engine compartment by ventilation on the ground, so that the safety of an engine and airborne equipment is ensured; the aircraft ground ventilation cooling device is vehicle-mounted, can be rapidly transferred to the field through a trailer when being required, and can be fixed to the ground through a brake, and can be reliably grounded during working, so that the bad influence of static electricity on the aircraft is prevented; a small diesel generator is arranged on the ventilation cooling device, and using is flexible; the strong cold air is provided by two high-power centrifugal fans, and the device can be applied to aircrafts of various types.

Description

technical field [0001] The invention relates to an aircraft ground ventilation and cooling method and a device thereof, belonging to the technical field of aircraft ground maintenance equipment. Background technique [0002] When the aircraft engine is working, it will generate high temperature due to high speed operation. High-power or densely installed airborne equipment also generates a lot of heat. When the aircraft is flying in the air, the generated flowing wind can quickly take away the heat in the engine compartment and equipment compartment through the air intake, thereby ensuring the normal operation of the aircraft engine and onboard equipment. [0003] When the airborne equipment of the aircraft needs to be powered on for a long time on the ground, and when the aircraft with the rear-mounted piston engine starts the engine for a long time on the ground, because the aircraft is stationary, the equipment compartment of the aircraft and the rear-mounted piston engi...
