    The invention disclosed relates to a cable-cutting device for cutting a cable under tension. The device is intended for use in conjunction with aircraft, particularly helicopters to provide reasonable protection to the rotor mast assembly, from cable strikes. The novel device comprises a pair of co-acting cable-cutting edges arranged at a suitable angle to produce a wedge-like mechanical advantage to at least partially cut a cable so that the cable will fail under moderate tension.

    4. The helicopter according to Clause I., of which there is a round neckline in place of the descent of the cutting edges.
    5. A helicopter for ni1 from which the routing and the fact that the cutting edges are made in the form of separate blade elements rigidly attached to the body of the cable-cutting device.
    6. The helicopter on n.l.o tl and h ayush and and with that. that the cable-cutting device is provided with a cable-deflecting device made in the form of plates with edges fastened to the case of the cable-laying device, and the edges of the to-abutment-deflecting device are smoothly matched with the cutting edges of the cable-cutting device.
    7. A helicopter according to claims 1 and 6, characterized in that each edge of the cable-deflecting device is made with a groove in which
    The hardened small-toothed saw blade is attached, with this cable disconnected, the undercutting device is whipped with the fuse.
    The invention relates to aeronautical engineering and concerns helicopters equipped with a device for protecting the power cable from collisions with aerial cables of electrical or telecommunication networks. The famous helicopter containing a fuse rail, bearing and tail rotors and powerplant fn. Also known is a helicopter containing a fuselage, in the nose of which is located the crew cabin bearing and tail rotor and powerplant 2. Known helicopters can fly at a low altitude in the area of installation of overhead cables of the electricity networks and communication networks. Under conditions of poor visibility, the likelihood of helicopters colliding with a cable is high. Practicing helicopters show 4to when striking a cable, there is a greater likelihood of damage to the nose (} landing gear rotor and control wiring, which leads to serious flight incidents. The aim of the invention is to provide protection against impact with air cables. The goal is achieved by the fact that the helicopter containing a body, in the nose of which the crew cabin is located, is equipped with a cable We restrain the device with a housing with a notch at the edges of which there are two cutting edges converging in the direction towards the tail part of the fuselage, and the housing is fixed to the fuselage in its forward part. In addition, the cutting edges converge at an angle of 5-10 ° j to form an isosceles triangle with a base equal to 50-100 mm, the cutting edges in the cross-section have the shape of an isosceles triangle, the angle at the top of which is 45-75. At the same time a circular cut is made in the place of the cutting edges. The cutting edges can be made in the form of separate blade elements rigidly attached to the body of the cable deck of its device. The cable-cutting device is provided with a cable-deflecting device made in the form of plates-with edges fastened to the cable-cutting device body, with the edges of the cable-declining device smoothly mated with the cutting edges of the cable-cutting device. Each edge of the cable-deflecting device can be made with a groove in which the hardened fine-toothed saw blade is rigidly fixed, while the cable-slope of the tweeter is connected with a fuse with a fuse. the nose of the helicopter is shown by cutting devices; Fig. 2 shows the assembly 1 in Fig. 1 (an embodiment of the cutting device of two parts); in FIG. 3 then TS. &. an embodiment of the cutting device with cutting edges in y or de separate blade elements; figure 4 - section aa on fig.Z; fig.Z - node and figure 1. On the helicopter, in the forward part of the fuselage 1, cable-cutting devices 2 and 3 having a housing 4 with a notch 5 along the edges of which are made along the edges 6 and 7j converge towards the tail part of the flywheel are fixed above and below. Edge 5-10. The cutting edges 6 and .7 in cross section are isosceles. the triangle has an angle at the apex of which is equal to 45-75 °. The cutting edges 6 and 7 are located in the same plane 8. And the front ends of the cutting edges are spaced to the base of the triangle 50-100 mm. In the places of vanishing of the cutting edges 6 7 there is a round cut-out 9. The cable-laying device (figure 2) consists of the body 4 and the cutting element 10. fastened together, for example, on rivets 11. The cutting edges 6 and 7 are made on the edges of them. The cut 5 of the housing 4 and the front edge of the element 10. The housing 4 is attached to the fuse 1; The cutting edges 6 and 7 of the cable-cutting devices 2 and 3 have continuations that are smoothly coupled to the cutting edges and fastened to them, forming a cable-breaking device, than on the front part of the continuations 12 is made a groove in which a rigidly locked tempered fine-toothed saw blade 13. with this cable-disconnecting device Connected by support 14 to fuse 1; In the embodiment (Fig. 3, the caudal device 2 (3) is a KOHCTpyKURIOj COCTOflnaya device from 4 or 4j, made of two plates 15 and 16 attached to the fuselage .1, which is equipped with a cable-deflecting device 17, wired in the form of a plate. Blades 18 and 19 are secured between the plates 15 and 16. The cutting edges 6 and 7 are respectively on them. The cable deflecting device .17 is made with edges, one of which has the shape of a broken line with portions 20 and 21 being a continuation of the cutting edge 5 and made of two uchas - section 22, equidistant fuselage 1 at the place of its installation, and section 23 in the form of a straight line, mating section 22 with a cutting edge 5, sections 20, 21 and 221, 23 of the cable 17 of the device 17 are equipped with a junction box D and In the sections 21 and 22, the cutting edges are made in the form of blades 24 and 25 of a fine-tipped band saw. In flying above the ground, it is likely that the helicopter collided with an air cable. In most cases, the helicopter collides with the nose part of the fuselage 1, the slide along which the cable 26 (FIG. 3) falls on the deflecting cable. device 17 and further onto cutting edges 6 and 7 of the cable-holding device 2, where the final cutting of the cable takes place, since the preliminary cut takes out the blade 25 of the cable-diverting device 17. In case cable 26 is meeting with the helicopter above the bypass the fuselage 1 prevents the rotor gearbox from impacting on the fairing. gripping the cable 26 with an upper edge of the cable-guiding device 17 which guides the cable to the cutting edges 6 and 7 and makes a preliminary cut of the cable. The lower part of the fuselage and the chassis are protected by a cable cutter 3, which operates similarly. . In order to protect the servicing loudspeaker from accidental cuts, the cutting edges of the cable-cutting device. may be covered with a thin layer of rubber or plastic.
