Abstract

The invention discloses a starting program control device and a control method of a turbofan. The starting program control device comprises a power circuit, an electromagnetic relay set and a time relay set, wherein the power circuit is connected with the electromagnetic relay set and the time relay set; the time relay set comprises multiple time relays; the electromagnetic relay set comprises multiple electromagnetic relays; the multiple time relays are correspondingly connected with the multiple electromagnetic relays and used for controlling switch-on or switch-off of corresponding electromagnetic relays at set time; and the multiple electromagnetic relays are respectively used for being connected to corresponding starting accessories of the turbofan. The starting program control deviceis small in size, light and low in manufacturing cost, the timing accuracy of the time relays is high, and thus the whole control device and the control method are high in control precision and highin reset and response speeds, an engine can control starting, cold working and false starting of the turbofan according to set programs and logic, and performance indexes meet the requirements.

Description

technical field [0001] The invention relates to the technical field of turbofan engine startup control, in particular, to a turbofan engine startup program control device and control method. Background technique [0002] The turbofan engine is mainly used to generate pull or thrust to provide flight power for the flight of the aircraft. At the same time, it provides electricity for the electrical equipment on the aircraft and provides air source for air-conditioning equipment and other air-consuming equipment. It is the heart of the aircraft. [0003] The starting procedure control method is to control the work of the starting accessories of the engine according to the specified timing and logic, and at the end of the starting, the starting accessories will stop working, so as to ensure that the automatic starting (including air starting), cold running and false starting of the engine follow the established procedures Finish. Due to the harsh working environment of the star...
