Abstract

The invention belongs to the aviation field, and relates to an airborne power generator cooling device, which is characterized by comprising a power generator set (1), an oil pump (2), a pressure relief valve (3), a first filter (4), a lubricating oil air cooling system, a temperature bypass valve (6), a non-return valve (7) and a second filter (8). The invention provides an airborne power generator cooling device, which solves the problem of cooling of the power generator in an aircraft full flight envelope range, particularly, in a low-speed condition, and avoids bad influences on the performance of the engine and the engine compartment appearance design.

Description

technical field [0001] The invention belongs to the aviation field and relates to an airborne generator cooling device. Background technique [0002] For turboprop aircraft, due to its small fuel consumption, if aircraft fuel is used to cool the generator, the heat sink brought to the aircraft fuel system is often unacceptable; if external air is used to cool the generator, in In low-speed conditions such as ground idle, take-off and landing, the amount of air that enters the engine compartment only by ramming is very limited, which cannot meet the cooling requirements of the generator; if the high-speed airflow is drawn from the engine, it is expected to increase the cooling air volume of the generator through ejection , will cause a decline in engine performance. Contents of the invention [0003] The purpose of the present invention is to provide a cooling method for an airborne generator, to solve the cooling problem of the generator in the full flight envelope of the...
