Problems solved by technology

However, due to the fact that the large duct is larger than the diameter of the fan blades, the casing weight is extremely sensitive to the thickness of the casing, and the increase in thickness directly leads to the overweight of the fan booster stage unit, which affects the fuel consumption of the engine

Abstract

The invention relates to a fan containing cartridge receiver and an aero-engine, and the fan containing cartridge receiver comprises a metal frame which is internally provided with a cavity; and the composite material layer is arranged on the periphery of the metal frame and forms the outer contour of the fan containing case after being integrally machined. According to the embodiment of the invention, the inclusiveness of the fan casing can be simultaneously increased, the increase degree of the weight of the engine is reduced, the material cost is saved, and the oil consumption rate of the engine is effectively reduced and the overall economical efficiency of the engine is improved under the condition of keeping the thrust of the engine.

Description

technical field [0001] The present disclosure relates to the field of aero-engine manufacturing, in particular to a fan-containing casing and an aero-engine. Background technique [0002] Axial-flow impeller case, typical of axial-flow aeroengine, consists of high-pressure and low-pressure dual rotors, and the low-pressure rotor includes two parts: a low-pressure fan at the inlet and a low-pressure turbine at the outlet. The fan containing casing, as an air intake working part of the aero-engine, is installed on the outside of the low-pressure fan, and is used to form the external air intake flow channel, contain the fan blades, prevent the fan blades from flying out abnormally, and reduce noise. [0003] The inclusive design of the fan casing is very critical: Although the current turbofan engine can operate for tens of thousands of hours without failure, if the fan blades break and the fan containing the casing is poor, it is easy to cause extreme damage. serious conseque...
