Description
Technical Field
The invention relates to a deicing system and a deicing method for an aircraft.
Background
In order to be able to safely maintain air traffic in the winter season, deicing of the aircraft is an absolutely necessary prerequisite under corresponding weather conditions. The aerodynamic properties are deteriorated by ice accretion because the buoyancy generated by the wings drops significantly, and the risk of icing of passenger and cargo aircraft during flight is relatively low because these aircraft move in high altitude areas above the cloud, without ice accretion being possible. In contrast, when the aircraft is on the ground, there is a risk of icing, particularly when the outside air temperature falls to freezing or precipitation. If an aircraft is in a high altitude area for several hours, where there is a two-digit negative temperature, the fuel-covered wing will immediately become covered with ice due to freezing precipitation, even at temperatures above freezing. Such ice layers form at a very high rate, and after a short stop in the middle, restarting without prior de-icing is no longer possible.
The main reason for the deicing of aircraft is that the deposition of ice and snow leads to high static wing loads, since the aircraft with entrained ice layer increases the flight weight during takeoff, in particular under unfavorable airport practical conditions, the extreme conditions encountered due to the failure of the tail, the icing and freezing of the wings or other moving parts for control and balancing, the blockage of holes in the pitot tube for speed measurement, and the interruption of the aircraft antenna and the occurrence of worst cases, radio communication being impossible. Ice build-up on the propeller can cause imbalance and the propeller can become caught in ice and run into danger. Eventually, aerodynamically, the situation becomes so bad that it crashes. Icing is therefore one of the biggest threats to air traffic accidents due to climate.

firstly, after a passenger plane 1 to be deiced enters a pre-deicing workshop 2, the passenger plane 1 to be deiced enters the pre-deicing workshop 2 through a front passage door, a front door air inlet pipe 9 blows a front shielding heat-insulating curtain 7 through a curtain central passage 8, and the front passage door is closed; then, gas is blown into the pre-air compressor 10 and enters the pre-heater 11 for heating, and meanwhile, salt particles in the pre-solid particle feeding hopper 23 enter the bypass air inlet pipeline 22 through the pre-feeding screw 24; secondly, the hot gas output by the preheater 11 drives salt particles into the pre-nozzle assembly component 16; again, the blow head nozzle assembly 17, the side wall annular nozzle assembly 18, the top nozzle assembly 19, and the bottom nozzle assembly 20 simultaneously blow hot gas mixed with salt particles onto the passenger aircraft 1 to be deiced;
after the passenger aircraft 1 to be deiced enters the main deicing workshop 3, firstly, outside air and a main air compressor 26 of gas heated by a preheater 11 enter a main three-way mixer 12 through a main heater 27, and meanwhile, bypass gas of the main heater 27 enters a bottom air inlet nozzle 29 through a bypass pipeline 28 to blow in airflow at an outlet of a channel of a pre-feeding screw 24; then, the underground storage pool 38 enters the main three-way mixer 12 through an underground liquid feeding pump 44, an underground heater 45 and an underground melt pressurizing pump 46; secondly, mixed gas and liquid sprayed out of the main three-way mixer 12 are sprayed onto the passenger plane 1 to be deiced through a main nozzle assembly component; thirdly, ice water and solution dissolved in the passenger plane 1 to be deiced enter the underground storage pool 38 through the bottom filtering ground row 37;
after the passenger plane 1 enters the tail-sweeping deicing workshop 4, firstly, the airflow output by the main heater 27 and the outside air enter the tail-sweeping air nozzle assembly 34 through the tail-sweeping air inlet pipeline 30; then, the gas ejected from the tail gas sweeping nozzle assembly 34 dries the passenger plane 1 to be deiced;
after the passenger plane 1 to be deiced enters the liquid film covering workshop 5, firstly, the airflow output by the tail sweeping air inlet pipeline 30 and the outside air enter the liquid film covering mixer 33, and meanwhile, the liquid film covering storage tank 31 enters the liquid film covering mixer 33 through the liquid film covering liquid feeding pump 32; then, the film-coating mixer 33 simultaneously sprays the airflow and the film-coating liquid onto the surface of the passenger aircraft 1 to be deiced;
and step five, finally, enabling the passenger plane 1 to be deiced to pass through a rear access gate 6.
In addition, in the second step, the main deicing workshop 3 deices the passenger plane 1 to be deiced simultaneously with the self-propelled deicing roller brush 52 of the self-propelled six-axis manipulator 49 according to the model setting program of the passenger plane 1 to be deiced;

The bottom filtering ground row 37 realizes filtering and water inlet, and the underground transverse moving seat 39 and the underground lifting seat 40 realize pushing deposited salt deposited on the filter screen out of the liquid level from the side. The underground inclined screen 42 is swung by the underground vibrating waterproof screw 43, thereby accumulating salt particles to the lowest point.
Circulation is realized by the underground liquid feeding pump 44, pipeline heating is realized by the underground heater 45, energy conservation and consumption reduction are realized, and the underground melt liquid booster pump 46 is used for boosting pressure.
The automatic driving is realized by the self-propelled base 47, the self-propelled lower supporting seat 48, the self-propelled six-shaft manipulator 49 and the self-propelled ice breaking roller brush 50. The hot air flow impacts the ice breaking through the self-propelled ice breaking air nozzle 51. The self-propelled top ice-breaking roller brush 52 is in direct contact, improving the deicing capability. The manual auxiliary ice breaking is realized through a manual walking base 54, a manual ascending ladder 55, a manual ascending screw 56, a manual top frame 57, a manual lateral moving screw 58, a manual transverse moving seat 59 and a manual ice breaking air nozzle 60, so that corners and dead corner areas are individually treated, and complete ice removal is realized.
