A method and system for identifying and generating operation path of aircraft idling deicing danger zone

Abstract

The invention belongs to the technical field of aircraft deicing operation route generation, and discloses a method and system for identifying a danger zone of aircraft idling deicing and generating an operation route. Establish the boundary curve function of the idling deicing danger zone of the current flight under no wind conditions according to the flight data such as the aircraft type information and the thrust direction information of the left and right engines. The movement paths of the intake and exhaust airflows are used to calculate the boundary curve function of the danger zone. According to the calculation results, the idling deicing danger zone of the aircraft under the influence of wind is demarcated; the internal and external safety passages of the engine are established and the deicing operation path is generated. The present invention describes the boundary functions of the idling deicing danger zone such as the aircraft air inlet, exhaust port, and engine reverse thrust, adds external influences such as wind speed and wind power, and adjusts the scope of the danger zone of the intake port and the exhaust port in combination with the boundary function. The accuracy of idle deicing operation is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft deicing operation route generation, and in particular relates to an aircraft idling deicing danger area identification and operation path generation method under all-weather conditions, and an aircraft idling deicing danger area identification and operation path generation system under all-weather conditions. Background technique [0002] Aircraft de-icing is a necessary work that needs to be completed before the aircraft takes off. There are many conditions for the aircraft to freeze. When the ambient temperature reaches below 0 degrees Celsius and the weather is accompanied by rain, snow, frost, etc., the aircraft may freeze. When the aircraft is in When flying through clouds at high altitudes, the water vapor in the clouds meets the wings or fuselage of the aircraft and may also freeze on the surface of the aircraft for a short period of time. The hazard of aircraft icing is serious. As we all...

AI Technical Summary

Problems solved by technology

[0005] (1) The current deication of aircraft idling deicing danger zone is still the division of danger zone under ideal conditions, and the influence of weather, especially wind conditions, on the danger zone has not been analyzed, and the wind force has a great impact on the danger zone, so the current There are insufficient divisions of dangerous areas for aircraft idling deicing, and an all-weather identification method for aircraft idling deicing dangerous areas is needed

[0006] (2) The operation path of aircraft idling deicing is currently mainly obtained from the safe passage of the engine obtained from the dangerous area, and the influence of wind speed and speed on the safe passage of the engine is also not analyzed. At the same time, if the wind fluctuates in a certain range, a An aircraft idling deicing operation path method under all-weather conditions

[0007] (3) In the prior art, because the safety factor of the aircraft idle deicing operation route generated by the wind fluctuation range is not introduced, it cannot be avoided that the dangerous area changed by the wind fluctuation will cause damage to the deicing operators and instruments
