AI Technical Summary

Problems solved by technology

In order to overcome the negative pressure of the airflow at the leading edge of the wing and transmit it to the aerodynamic horn in the front cabin through the pipeline, a relatively large negative pressure needs to be generated at the leading edge of the wing, which will cause a stall alarm delay problem in the traditional pneumatic stall warning system
Therefore, when designing an aircraft aerodynamic stall warning system, it is often necessary to reserve more stall margin to compensate for the delay of the aerodynamic stall warning system. This design method will reduce the maneuverability of the aircraft

Abstract

The invention provides a stall detector, an electronic pneumatic stall warning system and a general airplane. A stall detector for mounting to a wing of an aircraft includes: a weather vane blade extending from a leading edge of the wing and swinging in a direction of an upper airfoil of the wing under the action of a pressure difference between the upper airfoil and a lower airfoil of the wing; afixed lining plate which is arranged on the surface of the front edge of the wing, the fixed lining plate is provided with a limiting opening, and the weather vane blade extends out through the limiting opening; and a heating assembly which is arranged in the wing, is electrically connected with the weather vane blade and the fixed lining plate and is used for heating the weather vane blade and the fixed lining plate. The stall detector provided by the embodiment of the invention is more sensitive and quicker in stall detection.

Description

technical field [0001] The present application relates to the technical field of general aircraft, in particular to a stall detector, an electro-pneumatic stall warning system and a general aircraft. Background technique [0002] Among various factors that endanger flight safety, stall has always been one of the important factors affecting flight safety. Aircraft stall is a phenomenon in which the angle of attack of the aircraft exceeds the critical angle of attack and severe airflow separation occurs on the lifting surface of the wing, resulting in a sudden drop in lift and a sharp increase in drag. Along with the stall of the aircraft, there will be non-command rotations, such as wing drop, nose up, pitch oscillation and so on. Many aviation accidents are caused by going into a stall. [0003] The stall warning is a warning message sent to the pilot when the aircraft is approaching a stall. Its purpose is to provide a sufficient protection range between the stall warning...
