Problems solved by technology

When the helicopter is flying in the air, the engine's ITT, NG, and NF parameters are abnormal. The abnormality of these parameters is also a manifestation of the abnormal operation of the engine. These abnormal parameter information cannot be reproduced on the ground, so that the engine has a certain degree of safety. Hidden danger

Embodiment Construction

[0061] With the aid of the configuration of the helicopter cockpit display system, the present invention invents a method for collecting and displaying helicopter engine maintenance information, which mainly includes recording flight report information, historical fault information, current fault information, engine maintenance information, and engine power inspection information, in order to effectively calculate these The maintenance information does not affect the display of the cockpit display system. The maintenance information of the helicopter engine parameters can only be switched and entered by the switch key when the NG speed is less than 20%. Engine maintenance information can be downloaded and stored through the download interface.

[0062] System composition:

[0063] A method for collecting and displaying helicopter engine maintenance information of the present invention is mainly realized by means of a cockpit display system, such as Figure 10 , The cockpit di...

Abstract

The invention discloses a helicopter engine maintenance information acquisition and display method. A helicopter cockpit display system acquires and calculates engine maintenance information, and theengine maintenance information comprises flight report information, engine historical fault information, engine real-time faults, engine maintenance information and engine power inspection information. The flight report information, the engine historical fault information, the engine real-time fault, the engine maintenance information and the engine power inspection information are displayed on the helicopter cockpit display system. A pilot can visually observe the engine parameter information, and the workload of ground maintenance personnel can be reduced.

Description

technical field [0001] The invention belongs to the technical field of helicopter engine control and display, and relates to a method for collecting and displaying helicopter engine maintenance information. Background technique [0002] Existing helicopters manually record the history information of the engine through the pilot, and record the fault information that occurs in the helicopter. The records of these information are all based on the description of the pilot. The pilot manually records the flight time of the helicopter, the working time of the engine, etc. There are large errors. When the helicopter is flying in the air, the engine's ITT, NG, and NF parameters are abnormal. The abnormality of these parameters is also a manifestation of the abnormal operation of the engine. These abnormal parameter information cannot be reproduced on the ground, so that the engine has a certain degree of safety. Hidden danger. [0003] Especially for the fault information that ap...
