Abstract

The invention discloses an engine lifting structure, relates to the technical field of aeroengines, and solves the technical problem that the conventional lifting way has a greater impact on aerodynamic performance of an engine. The engine lifting structure comprises a hanger, at least two front lifting joints and at least one back lifting joint, wherein the hanger is connected with the engine through the front lifting joints and the back lifting joint; the at least two front lifting joints are connected with the hanger and the two sides of the engine respectively; the at least one back lifting joint is connected with the hanger and the top of the engine; the front lifting joints and the back lifting joint are connected to different positions in the axial direction of the engine respectively. The engine lifting structure is used for reducing the impact on the aerodynamic performance of the engine in the engine lifting process.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to an engine hoisting structure, especially a hoisting structure that can be used for hoisting an aero-engine. Background technique [0002] With the development of society and the continuous improvement of people's living standards, civil aviation, as a convenient and fast way of travel, has developed vigorously. At the same time, people put forward higher requirements for the safety, economy and comfort of civil aircraft. [0003] At present, high bypass ratio turbofan engines have been widely used in the power plant of large civil aviation airliners. The traditional hoisting methods of high bypass ratio turbofan engines include core engine hoisting and hybrid hoisting, among which: [0004] The hoisting structure using the core machine hoisting method is as follows: figure 1 As shown, in this structure, the front mounting section (or called: front hanging section) 201 and...
