Abstract

The invention discloses an automatic design method for a control law in a mode conversion process of a self-adaptive cycle engine, which is used for automatically calculating the control law in the mode conversion process after working condition parameters and the control law of a starting point and an ending point of the mode conversion process are given. The mode conversion design is simplifiedinto research of two key working points from a section of working process, the particle swarm optimization algorithm is combined with the sensitivity analysis method to solve the control rules of thekey working points, then the control rules of the whole mode conversion process are obtained, manual adjustment is not needed in the control rule solving process, and the working efficiency is improved. Design efficiency can be greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of overall performance simulation of an adaptive cycle aeroengine, and in particular relates to an automatic design of a control law in a mode conversion process. Background technique

[0002] The adaptive cycle aero-engine is a strategic technology highland that the international aero-engine powers are chasing after, and it is the extension and development of the concept of double-external variable-cycle aero-engine. The adaptive cycle aeroengine can flexibly adjust the cycle mode and cycle parameters of the engine through the mode selection valve, the adjustable guide vane of the rotating part, the variable area duct ejector and the nozzle, so that the engine can automatically adapt to the Flying in a wider speed range and airspace range meets the more stringent performance requirements of the engine for different missions.

[0003] Compared with the variable cycle engine, the adaptive cycle engine adds a...
