Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method provided by the application solves the problem that the fuel door authority of the prior advanced fighter mechanical throttle platform cannot be controlled and the problem of the operating authority of the front/rear cabin without a mechanical cross-linked fuel door platform through the design of an authority switch and constraint conditions.
According to the method and the device, on the premise of ensuring high safety input of a flight safety key system, the permission switch is adopted to trigger the permission switching request, whether the permission transfer condition is met is judged through the constraint condition, the safety of accelerator operation is improved, the risk brought by misoperation of a pilot is reduced, and meanwhile, clearer and more definite display is provided for the pilot to operate the accelerator control function.
The advanced fighter adopts the fly-by-wire system, the application of digital computer and bus technology, greatly improves the information processing capability and provides a platform for realizing more advanced control logic. The front/back cabin accelerator platforms are not mechanically linked, the front/back cabin pilots can operate the accelerator platforms, the accelerator instruction is closely related to the running response of the engine, and the flight safety is concerned.
As shown in fig. 1, the pilot may request throttle maneuver authority by pressing a throttle authority switch.
The above operation and decision logic is shown in fig. 1 and 2.
1. The normal steps for the front cabin pilot to obtain the accelerograph authority are as follows:
when the pilot presses the throttle permission switch, the flight control system starts timing after receiving the pressing signal, and when the pressing duration is less than 300ms, the flight control system does not respond to the permission switching request, so that the possibility of misoperation of the pilot is avoided; and triggering the throttle permission switching judgment logic after the pressing duration reaches 300ms, as shown in the attached figure 1.
If the current front cabin pilot obtains the throttle authority, finishing the judgment, and if not, entering the next judgment;
if the pilot presses the rear cabin throttle permission switch before the moment, finishing the judgment, otherwise, entering the next judgment;
if the following conditions are met, the front cabin pilot obtains the throttle control authority, lights the front cabin throttle authority lamp, extinguishes the rear cabin throttle authority lamp and prompts the pilot to switch the throttle authority through voice.
a) The front deck throttle lever is not in the parking position
b) The front cabin throttle is not in the unstable area of the engine
c) The engine is not in a stress application locking state
If any one of the conditions is not met, the front cabin pilot cannot acquire the accelerator control authority, and characters can appear in the cockpit to prompt the pilot that the authority switching is not successful, so that adverse effects on the engine caused by the fact that the front cabin accelerator state does not meet the normal operation requirement of the engine are effectively avoided.
2. The normal steps for the cockpit pilot to obtain the accelerograph authority are as follows:
when the pressing duration is less than 300ms, the flight control system cannot respond to the permission switching request, so that the possibility of misoperation of the pilot is avoided; and triggering the throttle permission switching judgment logic after the pressing duration reaches 300ms, as shown in the attached figure 2.
If the pilot of the front cabin and the rear cabin obtains the throttle authority, finishing the judgment, otherwise, entering the next judgment;
if the front cabin pilot presses the front cabin throttle permission switch before the moment, finishing the judgment, otherwise, entering the next judgment;
if the following conditions are met, the pilot in the rear cabin acquires the throttle control authority, lights a throttle authority lamp in the rear cabin, extinguishes a throttle authority lamp in the front cabin, and prompts the pilot to switch the throttle authorities through voice.
a) The rear oil door rod is not at the parking position
b) The rear cabin throttle is not in the unstable area of the engine
c) The engine is not in a stress application locking state
If any one of the conditions is not met, the pilot in the backseat cannot acquire the accelerator control authority, and characters can appear in the cockpit to prompt the pilot that the authority switching is not successful, so that the adverse effect on the engine caused by the fact that the accelerator state in the backseat does not meet the normal operation requirement of the engine is effectively avoided.
3. Accelerator instruction comprehensive method
The accelerator instruction output to the engine is comprehensively controlled according to the authority, and the comprehensive control method specifically comprises the following steps:
a) if the throttle authority is in the front cabin authority, outputting a throttle instruction as a front cabin throttle instruction;
b) and if the throttle authority is in the rear cabin authority, outputting a throttle instruction as a rear cabin throttle instruction.
It should be noted that, the application of the full-electric throttle platform to the advanced fighter greatly improves the control accuracy of the pilot and lays a foundation for the subsequent realization of more advanced throttle control logic. Because the front cabin and the rear cabin are not mechanically crosslinked, the throttle platforms can be independently operated, and are closely related to the normal operation of the engine, the protection of the engine must be considered, and if the problem cannot be well solved, a series of potential safety hazards are inevitably brought.
By introducing a high-safety throttle authority management and instruction comprehensive method, the sequential switching of the front/rear cabin throttle platform authorities is realized, the reasonability and the safety of throttle instructions output to an engine are further guaranteed, the problem of the control authority of the front/rear cabin throttle platform without mechanical cross-linking is solved, clear and definite light and voice/character prompts are provided for a pilot, and the risk of the pilot caused by misoperation on flight safety is eliminated. The method belongs to the initiation of China and China, has certain innovativeness, and is successfully applied to the design of certain airplanes.
The method for achieving the accelerator authority switching and the instruction comprehensive control includes that firstly, all-electric accelerator platforms are adopted for the front cabin and the rear cabin, and flight control system software analyzes corresponding front cabin and rear cabin switch signal states according to interface definitions and identifies corresponding engine state signals according to relevant limiting conditions of an engine.
The flight control system needs to implement a series of condition judgment for switching the authority according to the connection state of the accelerator authority switch, and the condition judgment comprises the following steps: the current throttle authority state, the throttle lever position and the engine stress application locking state so as to eliminate the risk of the misoperation of the pilot on the flight safety. In addition, the flight control system also needs to display light, voice and characters according to the permission switching state so as to ensure that the pilot can clearly and definitely know the permission state of the accelerator.
The foregoing is merely a detailed description of the embodiments of the present invention, and some of the conventional techniques are not detailed. The scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention will be covered by the scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
