Aero-engine rectifier cover based on Magnus effect

Abstract

The invention discloses an aero-enginerectifier cover based on the Magnus effect. The autogyration rectifier cover is in a sphere shape. Prostrate crescent protrusions are arranged on the sphere anticlockwise. A mounting edge is arranged on the outer ring of the front end of an air inlet machine. A special-shaped rectifier supporting plate is welded to the front end of the air inlet machine. Holeswith stairs are formed in horizontal two ends of the autogyration rectifier cover. The holes are self-lubricating bearing outer ring mounting seats. Stair shafts are arranged on the left and right sides of the air inlet machine in the horizontal direction of the autogyration rectifier cover. The shafts are self-lubricating bearing inner ring mounting seats. The autogyration rectifier cover is mounted on the air inlet machine through a self-lubricating bearing. A groove bearing mounting seat is arranged at the middle of the air inlet machine. A front fulcrum bearing is arranged in the bearingmounting seat and is locked by nuts. A sealing component is arranged at the front end of a low-pressure rotor in a sleeving mode. The low-pressure rotor is connected to the front fulcrum bearing. A low-pressure stator is arranged at the rear end of the air inlet machine. The structure is rational, and ice resisting and ice removing systems of the aero-engine can be omitted.

Description

technical field [0001] The invention relates to the technical field of aero-engine cowling, in particular to an aero-engine cowling based on the Magnus effect. Background technique [0002] The aero-engine fairing cover is the frontmost part of the engine main engine, and its main function is to rectify the incoming air and introduce the incoming air into the fan or low-pressure compressor. The traditional aero-engine cowling is generally hemispherical or conical, and is a stator. In order to prevent the aero-engine from icing and falling off during flight, and damage the engine flow passage, the high-pressure compressor of the aero-engine is connected through an external pipeline. The high-pressure, high-temperature air is introduced into the aero-engine cowling cover to heat the cowling cover, thereby preventing or blowing off ice accumulation. The main disadvantage of the traditional fairing cover is that a set of anti-icing and de-icing systems need to be installed on t...

AI Technical Summary

Problems solved by technology

The main disadvantage of the traditional fairing cover is that it is necessary to add a set of anti-icing and de-icing systems to the engine, which increases the complexity of the aero-engine control system

At the same time, the fairing cover is a stator part, which has no other purpose except to rectify the airflow, let alone generate the lift required by the aircraft.
