Problems solved by technology

The existing aircraft snow removal method is to spray aircraft anti-icing liquid to the surface of the aircraft. The main components of the anti-icing liquid used are methanol, ethanol (alcohol), ethylene glycol, etc. This anti-icing liquid has a low condensation temperature and can be mixed with water Good performance, strong adhesion to the anti-icing surface, no chemical corrosion on the anti-icing surface, non-toxic, and good fire resistance, so it is widely used in aircraft deicing, but the cost of this type of anti-icing fluid is relatively high
[0003] Chinese patent CN109987247A discloses a steam jet multifunctional aircraft deicing vehicle, which includes a vehicle body, a steam generating device, a steam delivery device, a deicing executive device, de-icing control system, etc. The steam generating device of the de-icing vehicle uses fuel oil as the power source, which can generate high-temperature saturated steam and high-temperature air, including: water tank, water pump, blower, steam generator; the water tank is used as a steam generator through the water pump Provide water source; the blower provides air for the steam generator to generate steam and high-temperature air with different humidity and saturation. The deicing actuator of the deicing vehicle cannot generate steam and high-temperature air at the same time. To dry ice water, due to the low outdoor temperature, if the ice water that melts first is not evaporated in time, it is easy to freeze again, which will affect the deicing efficiency. ice cart

Description

technical field [0001] The invention relates to the technical field of aircraft deicing, in particular to a novel steam jet multifunctional aircraft deicing vehicle. Background technique [0002] Under icing conditions, ice, snow, and frost will have a direct impact on the operational safety of the aircraft, making the outer surface of the aircraft rough, increasing the weight of the aircraft, limiting the range of movement of the aircraft control surfaces, and causing instrument errors. Cause the aircraft to stall and instantly abnormally pitch up, so that the flight performance of the aircraft will be greatly reduced, especially when the aircraft takes off and ascends, it will make the flight attitude difficult to control, and seriously cause an air crash. Unfavorable weather conditions in winter can bring serious hazards to aircraft. Therefore, in order to ensure normal shipping and flight safety, the frost and snow on the surface of the aircraft must be removed. The ex...
