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

Abstract

The invention belongs to the technical field of airplane deicing operation route generation, and discloses an airplane idling deicing danger zone identification and operation path generation method and system. The method comprises the following steps of: establishing a boundary curve function of an idling deicing dangerous area of a current flight under a windless condition according to flight data such as aircraft type information and thrust direction information of left and right engines, establishing a motion path of intake and exhaust air flows of the engines according to the influence of an intake duct dangerous area and an exhaust duct dangerous area of an aircraft, and calculating a dangerous area boundary curve function according to the motion path; according to a calculation result, an aircraft idling deicing danger area under the influence of wind power is delimited; and internal and external safety channels of the engine are established, and a deicing operation path is generated. According to the method, by describing the boundary functions of the idling deicing dangerous areas such as the air inlet channel, the exhaust port and the engine reverse thrust of the airplane, adding external influences such as wind speed and wind power, and adjusting the dangerous area ranges of the air inlet channel and the exhaust channel in combination with the boundary functions, the idling deicing operation precision is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft deicing operation route generation, and in particular relates to a method for identifying dangerous areas of aircraft idling deicing under all-weather conditions and generating an operating path, and a system for identifying dangerous areas for idling deicing and generating operating paths under all-weather conditions. Background technique [0002] Aircraft deicing 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 is below 0 degrees Celsius and accompanied by rainfall, snowfall, frost, etc., the aircraft may freeze. When the aircraft is in the When flying through the clouds at high altitude, the water vapor in the clouds may also freeze on the surface of the aircraft in a short time when it meets the wings or fuselage of the aircraft. The danger of aircraft icing is serious. As we all kn...
