Detailed Description

The design method according to the present invention will be described in further detail with reference to the accompanying drawings.

A design method for the comprehensive display of a helicopter flight control system is mainly used for monitoring the working state of the flight control system by a driver in the flight process, can also be used for ground self-detection and fault elimination to provide state display, and can quickly locate the fault reason, and referring to figure 1, the comprehensive display of the helicopter flight control system is realized by the following modes and steps:

1) the function of indicating the position of the control surface is realized in a multifunctional device

The helicopter flight control system is characterized in that the prototype flight control system is provided with a pitching, rolling and course control surface position indicator, the control surface position indicator is arranged on an instrument and used for displaying the output quantity of a series-connection steering engine of the flight control system, signals are transmitted through a simulation cable, the system architecture is optimized, the helicopter flight control system is provided with three control surface position indicators, the output quantities of the pitching, rolling and course series-connection steering engine are transmitted to a comprehensive task processing system in a GJB289A bus form, and the output quantities are displayed on a multifunctional display according to a prototype physical model of the control surface position indicator.

2) Digital tube for canceling flight control console panel

The helicopter flight control system cancels the display of the nixie tube, and displays the fault information of the flight control system on a multifunctional display through Chinese within a cross.

3) Increasing flight control modal investment information display

After the relevant modes of the flight control system are input, the relevant mode buttons and the like on the flight control console can be lighted, but due to the fact that the view of the installation position of the flight control console is poor, the button switches of the flight control console panel are distributed, and the current working state of the flight control system is difficult to directly read, the helicopter flight control system transmits the information to the comprehensive task processing system through a GJB289A bus form to be comprehensively displayed on the multifunctional display, and the modes are classified according to the longitudinal axis, the heading and the total distance.

4) Increasing flight control system prompt information display

The flight control system carries out self-detection or puts in a functional mode in the air, certain conditions are required to be met, the flight control system has complex structure and cross-linking, and the reasons which do not meet the conditions are multiple, so great difficulty is brought to ground troubleshooting and air adjustment, the helicopter flight control system integrates various reasons which do not meet the conditions, the various reasons are transmitted to the integrated task processing system through a G289 JB289A bus form to be comprehensively displayed on the multifunctional display, and in the process of self-detection or putting in the mode, prompt information can be popped up as long as obstacles appear, and ground service or air service correction and adjustment are guided.

5) Flight control system integrated display area is concentrated

The position indication (pitching, rolling and course) of a control surface, flight control mode input information (control stability augmentation/stability augmentation and the like, airspeed maintenance/automatic hovering and the like), and prompt information display (flight control system self-detection steps and results, information such as reasons for mode input failure, abnormal mode exit, flight control disconnection prompt and the like) of the flight control system are all information needing attention at any moment in the normal flight process, and the multifunctional display is provided with a special display area for the flight control system to carry out comprehensive display, so that the load of a driver is reduced.

The technology has the advantages that:

1) direct view and clarity

The failure information declaration designed by the method does not need the driver to memorize hard backs, carries out guidance prompt information given by self-detection before flight and modal investment, can quickly position the reason that the flight control system does not meet the conditions, realizes 'fool' use of the flight control system, and reduces the workload of air ground personnel.

2) Display integration

The method displays the position indication, the mode input and the prompt information of the control surface on the multifunctional display, optimizes the system architecture, has high integration level with an avionic system, and is greatly convenient for the operation and the use of crew members in a comprehensive display mode.

3) Wide application range

The comprehensive display design method of the flight control system is suitable for all digital configuration flight control systems, electric flight control systems and future light transmission flight control systems.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the original scope of the invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
