Abstract

The invention discloses an icing tunnel experiment device for an air intake duct support plate of an aeroengine. The icing tunnel experiment device comprises an icing tunnel experiment cabin, an installation base, a support unit, a first pipeline and a second pipeline, wherein the installation base is detachably connected with the icing tunnel experiment cabin, the support unit is fixed on the installation base, the air intake duct support plate having a cavity with an inlet end and an outlet end is fixed on the support unit, the second pipeline communicates with the inlet end and is used for inputting a thermal medium into the cavity of the air intake duct support plate, and the first pipeline communicates with the outlet end. When an engine is in an environment where icing is likely to occur, a high temperature medium is pumped in the internal cavity of the air intake duct support plate to increase the temperature of the external surface of the air intake duct support plate to prevent icing on the external surface of the air intake duct support plate. When the air intake duct support plate of the engine is frozen, a high temperature medium is pumped in for deicing to prevent the engine performance from being affected due to sharp decreasing of intake air.

Description

technical field [0001] The invention relates to an anti-icing test device of an aero-engine, in particular to an ice-wind tunnel test device for an aero-engine air inlet support plate. Background technique [0002] Flight icing is one of the important causes of safety accidents in modern flight safety. Through the study of a large number of flight safety accidents in the past, it is shown that in some key parts of the aircraft, a small amount of icing will also affect the aerodynamic performance, maneuverability and stability of the aircraft. For aero-engines, the parts that are most likely to freeze are the air intake components. The icing of the air intake components may block the air intake flow path of the engine, and even cause intake distortion, resulting in a sharp decrease in thrust. If the ice on the intake components falls off, it may hit the fan blades of the engine or the rotor blades of the compressor, causing serious mechanical damage, which in turn leads to d...
