Abstract

The invention discloses an outfield test maintenance method and device of an aviation engine. The method includes the steps of: sending control instructions to an electronic controller, wherein the control instructions include a state checking control instruction, a fault checking control instruction, and a return-to-zero control instruction; and receiving response information of the electronic controller, entering a corresponding function mode, and communicating with the electronic controller in the corresponding function mode so as to test working states of the aviation engine and the electronic controller. The outfield test maintenance method and device of the aviation engine provide effective means for maintenance persons to quickly locate and investigate engine faults, solve the problem of outfield test maintenance of the aviation engine and the electronic controller, greatly reduce the ground staff work intensity and work difficulty, and save the maintenance time. The operation is simple, and the practicability is strong.

Description

technical field [0001] The invention relates to the field of testing of aero-engines and electronic controllers, in particular to a field test and maintenance method and device for aero-engines. Background technique [0002] As the core power component of the aircraft, the aero-engine provides thrust or pull for the aircraft to overcome the inertia and air resistance when the aircraft is flying. The aero-engine determines the key performance of the flight, such as carrying capacity, voyage length and reliability, and is known as the "aircraft engine". Therefore, before the flight takes off, ground crews are required to perform daily maintenance on the aero-engine to ensure the safe flight of the aircraft. The daily maintenance of the aero-engine includes checking the state parameters of the various sensors of the aero-engine, the counter information of the electronic controller, Working status information of aeroengine and electronic controller, fault information of aeroengi...
