Aircraft icing: An ongoing threat to aviation safety

Hình ảnh có liên quan

Aircraft icing can cause severe aerodynamic and flight mechanical effects, thus threatens aircraft flight safety. First, the causes, types, severity and natural parameters of aircraft icing are introduced. Finally, a series of aircraft flight accidents caused by icing in recent years are analyzed.

The foregoing content is a systematic and comprehensive review of the supercooled droplet icing issues on aircraft. The first part analyzes the causes of ice accretion on aircraft. The second part introduces the types and severity of aircraft icing. Ice accretion on aircraft is classified into rime ice, glaze ice and mixed ice based on its property. Mixed ice is one of the most common icing forms in reality. It is more dangerous that greater inertia and impact efficiency of the rain droplets will result in ice accretion beyond the icing boundary of the normal droplet, sometimes beyond the protection area of the anti-icing or de-icing system. At present, SLD icing is one of the hottest research directions in the field of aircraft icing, especially on SLD icing mechanism, aerodynamic and flight performance changes caused by SLD icing and ice shape formed under the co-working of the icing conditions of SLD and the anti-icing system. Some measures are necessary to deal with problems of aircraft flight safety in icing conditions, especially these SLD icing conditions.
