Problems solved by technology

However, these above-mentioned experimental devices have the following disadvantages: these devices are mainly used for environmental simulation of electrical experiments, and do not have deicing fluid spraying systems, wind direction adjustment, and lighting systems, so their functions are far from meeting the requirements of aircraft surface icing experiments

Abstract

An environment analogue means for surface freezing of airplanes on ground. The means comprised an experiment case and a suspension positioning device installed inside or outside of the experiment case, an air cycling device, a spray system, an ice clearing liquid spray system, an illumination system, a refrigeration system, a data acquisition system and a control system. The invention provided environment analogue means for surface freezing of airplanes on ground can simulate freezing weather condition of natural environment in truth, Observing processes of ice increasing, ice melting and iceclearing liquid spraying on airplane surface, Thereby rules of icing on airplane surface in different weather condition can be obtained, Which can provide experiment basis for research of airplane surface icing and airplane surface ice proofing / deicing, Finally improving security and high effectiveness of airplane operation in icing weather condition.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to an environment simulation device for icing on the surface of an aircraft on the ground. Background technique [0002] Under low-temperature icing conditions, ice, snow, and frost will appear on the surface of aircraft parked on the apron, which are collectively referred to as aircraft surface icing. On the one hand, ice accumulation on the surface of the aircraft will affect the safety and operability of the flight, and in severe cases, it will lead to accidents involving aircraft crashes and fatalities; on the other hand, it will also cause the flight to fail to operate normally. According to statistics, during the period from January 10 to February 4, 2008, due to the low temperature, rain, snow and freezing weather in the south, a total of 814 flights returned and alternated, more than 4,600 flights were canceled, and more than 13,500 flights were delayed, r...
