Problems solved by technology

[0002] Existing helicopters use the traditional engine parameter interface display, the display interface is single, the displayed alarm information is independent of the display system, and each parameter display device is completely independent. Once the transmission signal is interrupted, there is no backup display function

Embodiment Construction

[0117] The engine parameter display is calculated and displayed by the cockpit display system of the helicopter. The helicopter cockpit display system consists of three displays, left PFD+MFD+right PFD. ESI parameters and three-needle speed indicator are displayed on the lower left part of PFD, and engine parameters are displayed on the middle and lower part of MFD. ESI parameters are calculated by left and right PFD and MFD.

[0118] The left and right PFDs and MFDs collect the bus information and sensor information from the ESC respectively. Under normal circumstances, the information used for ESI calculation display and engine parameter display comes from the bus information output by the ESC. When the bus information from the ESC fails Or when the ESC detects that the sensor collected by the ESC fails, the system automatically collects the information output by the engine sensor for the calculation and display of ESI parameters.

Abstract

The invention belongs to the field of helicopter design and specifically relates to a display system and method for helicopter engine parameters. The display system and method are used for improving the man-machine effect. Traditional engine parameter interface display is adopted for an existing helicopter, a display interface is single, and displayed alarm information is independent of a display system; all parameter display devices are completely independent, so that once transmission signal interrupt and other conditions occur, a backup display function is not available. According to the display system and method on the basis that the construction of a cockpit display system is fully used, on the premise of taking the system safety into consideration, the engine parameters are recombined and optimized, so that the flying difficulty is relieved, and meanwhile, the display interface for the engine parameters is clearer and more concise.

Description

technical field [0001] The invention belongs to the field of helicopter design, and in particular relates to a helicopter engine parameter display system and method, which are used to improve ergonomics. Background technique [0002] Existing helicopters use the traditional engine parameter interface display, the display interface is single, the displayed alarm information is independent of the display system, and each parameter display device is completely independent. Once the transmission signal is interrupted, there is no backup display function. Contents of the invention [0003] The technical problem to be solved by the present invention is: on the basis of making full use of the configuration of the cockpit display system and considering the safety of the system, the present invention reorganizes and optimizes the engine parameters to reduce the difficulty of driving and at the same time make the display of the engine parameters The interface is more clear and conci...
