The invention relates to a horizontal tail front edge for a bird strike-resisting airplane. An upper honeycomb sandwich layer, a lower honeycomb sandwich layer, a front edge reinforcing member and an aerofoil lining layer are arranged among spans on the horizontal tail front edge in a spanwise mode along a horizontal tail of the airplane; one angle of the front edge reinforcing member is positioned at the front end of the horizontal tail front edge; the upper honeycomb sandwich layer and the lower honeycomb sandwich layer which are in a shape of a parallelogram are fixed on upper and lower internal surfaces of a horizontal tail skin respectively, the edge of one vertex angle of each honeycomb sandwich layer is fixed with surfaces of the front edge reinforcing member and the horizontal tail skin respectively, and the edge of the other vertex angle is fixed with the surfaces of the horizontal tail skin and the aerofoil lining layer; and the honeycomb sandwich layers and the front edge reinforcing member are coated between the aerofoil lining layer and the internal surfaces of the horizontal tail skin by the aerofoil lining layer. In the horizontal tail front edge, birds are cut by the front edge reinforcing member, the impact force of the birds is absorbed by the honeycomb sandwich layers, and an internal structure of the horizontal tail front edge is protected against damage bythe aerofoil lining layer. The horizontal tail front edge is also suitable for vertical tails, aerofoil front edges and all beam edges which are likely to be subjected to bird strike on the airplane.

The present invention relates to a tail for improving anti-bird strike performance of an aircraft. A leading edge reinforcement having a shape of an isosceles triangle is located inside a tail leading edge. The leading edge reinforcement is spanwisely fixed in sections between respective spans formed by the wing rib inside the tail leading edge along the tail of the aircraft. An apex angle of the leading edge reinforcement is the same as an apex angle or arc transition of the tail leading edge skin. The leading edge reinforcement is fixedly connected with the small front beam by a leading edge reinforcement fixed surface. The present invention additionally installs a leading edge reinforcement in the original tail of the aircraft.

The invention provides a supporting body for a bird strike-resistant aircraft leading edge. The supporting body comprises an auxiliary beam, a front beam and a leading edge cabin rib, wherein the auxiliary beam is positioned at the front part of the leading edge and stretches longitudinally; the auxiliary beam is corrugated and comprises a front surface side and a back connecting side opposite tothe front surface side; the front beam is positioned on the back part of the leading edge and stretches longitudinally; the leading edge cabin rib is positioned between the auxiliary beam and the front beam; the leading edge cabin rib comprises a front connecting end and a back supporting end opposite to the front connecting end; the auxiliary beam is attached to the back side of leading edge skinof the leading edge so as to form a cavity between the auxiliary beam and the leading edge skin; the back connecting side of the auxiliary beam is connected to the front connecting end of the leadingedge cabin rib through a connecting component; the back supporting end of the leading edge cabin rib is fastened to the front beam through a fastening component. The invention further provides the bird strike-resistant aircraft leading edge using the supporting body. According to the invention, the bird strike resistance of the leading edge of a wing is significantly improved.

An aircraft avian radar is implemented using multiple axial beam antennas mounted on an aircraft. Target range is determined by radar range. Target azimuth and elevation position is determined by triangulation. An end-fire array antenna composed of a series of monopole antenna elements enclosed inside a long thin protective cover fashioned in the form of a stall fence is mounted on the wings, tail, or fuselage to produce a low drag axial beam antenna pattern directed ahead of the aircraft. Other axial beam antenna choices include helical, pyramidal horn, and conical horn antennas mounted on or inside various forward facing surfaces of the aircraft.

To provide a projectile for bird strike tests, comprising a gel-like or jelly-like material, which makes reproducible and representative results in bird strike tests possible, it is proposed that the projectile comprise a stabilizing device arranged in the projectile for stabilizing the gel-like or jelly-like material.

The present invention is a helicopter lighting system. In particular, the present invention is directed to a helicopter lighting system with light that is directed toward a helicopter's rotors to deter bird strikes. The helicopter lighting system preferably has at least one light mounted on the helicopter's tail aimed at the tail rotor, where illumination from the at least one light comprises ultraviolet light between 300 and 400 nm in wavelength and the at least one light flashes at a pre-determined frequency, preferably between 1 Hz and 3 Hz. The light system further preferably comprises at least one roof light mounted on the roof, where illumination from the roof light shines on the main rotor and vertical shaft of the helicopter. The lighting system also preferably has a belly light mounted on the belly of the helicopter.

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.
