Problems solved by technology

[0003] The currently used intercooler is usually installed on the side or belly of the aircraft fuselage. However, since the function of the intercooler is to exchange heat between the pressurized air and the external ambient air, the external ambient air needs to enter the intercooler. Therefore, it is necessary to arrange additional air inlet and outlet channels, occupying a larger space, increasing the external contour size of the aircraft, and increasing the flight resistance
In addition, a longer pipeline will cause greater pressure loss, reducing the intake rate and pressure, and the performance of the engine will also be reduced

Abstract

The invention discloses a device and method for installing an intercooler in an aviation piston engine. The device includes a mounting bracket and a shock absorber assembly; wherein, the mounting bracket is fixed on the reduction gearbox of the aviation piston engine; and the intercooler is fixed on the mounting bracket via the shock absorber assembly. The intercooler in the present invention is fixed on the engine deceleration gearbox through the mounting bracket, utilizes the existing unused installation points on the deceleration gearbox, makes full use of the space in the engine compartment, reduces the layout space occupied by the aircraft body, and avoids the air pollution outside the aircraft body. The profile size is increased to avoid the increase of aircraft flight resistance.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a device and method for installing an intercooler in an aviation piston engine. Background technique [0002] The intercooler is a component that cools the air after the turbocharger is supercharged, and is actually a turbocharged accessory. When the aviation piston engine is used at high altitude, the air flows through the turbocharger for supercharging, and the temperature of the supercharged gas rises sharply. Therefore, it is necessary to cool the gas entering the intake pipe, and its function is to reduce the supercharged air temperature. , in order to reduce the heat load of the engine, increase the intake air volume, and then increase the power of the engine. [0003] The currently used intercooler is usually installed on the side or belly of the aircraft fuselage. However, since the function of the intercooler is to exchange heat between the pressurized air and the e...
