Embodiment Construction

[0017] figure 1 Among them, the two ends of the elastic telescopic device (4) composed of several evenly distributed telescopic units are mechanically connected to the outer edge of the engine air inlet (3) and the outer edge of the mesh barrier layer (6), and the mesh barrier layer (5 ) can do reciprocating motion parallel to the flight direction of the aircraft under the action of external force; Compress the elastic telescopic device (4) after the force, and move toward the tail of the aircraft, most of the impact energy is absorbed, and prevent the birds from entering the engine air inlet (2); the mesh barrier layer (5) can also be elastically Pop the bird and drop it. In order to prevent the mesh barrier layer (5) from blocking the engine air inlet due to freezing, an electric heating anti-icing device is also provided on it, and the power supply (7) is connected to the mesh barrier layer (5) through a wire (8). The heating resistance has two stages, and the power suppl...

Abstract

The invention relates to the airplane safety field, and especially relates to a method of setting an elastic anti-bird strike net in an aircraft engine air inlet; the method comprises the following steps: setting a netted barrier layer vertical to an aircraft engine air inlet air-flow running direction in the aircraft engine air inlet, wherein each grid of the netted barrier layer is smaller than a normal bird size, the outer rim of the netted barrier layer is matched with that of the aircraft engine air inlet, and the barrier layer and the air inlet are mechanically connected through an elastic telescopic device so as to make telescopic motions parallel to the airflow running direction; the netted barrier layer is provided with an anti-icing heating device; when a bird hits the anti-bird strike net, an elastic telescopic unit of the elastic telescopic device can make telescopic motions approximately parallel to the bird hitting direction, thus absorbing the bird hitting energy; the method can use the anti-bird strike net to absorb bird kinetic energy so as to enhance anti-bird strike intensity; in addition, the anti-bird strike net is provided with the anti-icing heating device, so the anti-bird strike net cannot be frozen, and thus blocking the aircraft engine air inlet.

Description

Technical field [0001] The invention relates to the field of aircraft safety, in particular to a method for arranging an elastic anti-bird collision net at an air intake of an aircraft engine. technical background [0002] At present, the known anti-bird strike device for aircraft, especially the anti-bird strike device for the engine air inlet, is always a weak link. The main reason is that if the engine air intake is equipped with anti-collision nets, although it can play a little role in flying birds, there are always two serious problems: one is that the anti-collision nets are not strong enough when the birds and the aircraft are moving relatively at high speed, The other is that if the anti-collision net freezes, it will affect the air intake of the engine air intake, and may even block the engine air intake, causing serious consequences. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention proposes a met...
