De-icing system of aircraft engine inlet

Abstract

The invention relates to a de-icing system of an aircraft engine inlet, and belongs to the field of design and manufacture of aircrafts. The de-icing system of an aircraft engine inlet comprises an engine inlet, a hot-gas gathering device, an air gathering pipe and an exhaust pipe, the engine inlet is provided with an interlayer; an air gathering vent is arranged on the exhaust pipe of the aircraft engine. The de-icing system provided by the invention can be used for de-icing to the aircraft engine inlet with the hot gas of the exhaust pipe of the aircraft engine, the disadvantage that the engine performance is changed caused by gathering hot gas from a compressor of the engine in the process of de-icing with hot-gas is overcome, the system has good de-icing effect, simple structure, convenient operation, is suitable for aircrafts of various types or specifications, safety indexes of aircrafts in severe weather conditions can be enhanced greatly, and a flight accident caused by the air inlet structure of an engine can be prevented.

Description

technical field [0001] The invention belongs to the field of aircraft design and manufacture, and in particular relates to an engine air inlet deicing system of an aircraft. Background technique [0002] When an aircraft flies in icy weather conditions, the windward surfaces of certain components collide with, accumulate and freeze water droplets in the atmosphere. A large number of accidents and studies have shown that even a small amount of ice accumulation on key parts of the aircraft will lead to a decrease in the lift of the aircraft and an increase in flight resistance, which will lead to deterioration of the aerodynamic qualities of the aircraft such as maneuverability and stability. The icing of the engine inlet and air intake parts destroys the aerodynamic shape of the aircraft design, reduces the area of ​​the inlet, and also reduces the air circulation area between adjacent blades of the compressor of the aircraft engine, so that the air entering the engine The a...
