RU73306U1 - HELICOPTER - Google Patents

Abstract

The utility model relates to aviation, in particular to means of saving passengers and aircraft, and can be used to create promising helicopters with increased passenger safety.

The objective of the utility model is to simplify the design and reduce the danger of use by reducing the number of locations of explosives.

This goal is achieved by the fact that in a known helicopter containing a propeller with blades and a fuselage, consisting of the bow with the cockpit, the central and tail parts, where the passenger compartment is located in the central part in the form of a sealed autonomous compartment equipped with a parachute, made with the possibility of separation from the bow with the cockpit and the tail, the new thing is that the sealed autonomous compartment is attached directly to the tail boom connecting the bow with the cockpit and the tail st, and as a means of separating the sealed autonomous compartment, there are special explosive fastening bolts - known as “pyro bolts”.

Such a design is much simpler than the known ones and provides a reduction in the danger of use by reducing the number of explosive locations.

Description

The utility model relates to aviation, in particular to means of saving passengers and aircraft, and can be used to create promising helicopters with increased passenger safety.

The technical solution closest to the technical essence adopted for the prototype is a helicopter, which contains an integral fuselage and is configured to accommodate a passenger compartment in the fuselage, consisting of a sealed autonomous capsule compartment, which is placed in the helicopter through the opening wings of the rear of the fuselage. In the fuselage there are devices made with the possibility of separating (cutting) parts of the helicopter body from an autonomous capsule compartment. The doorways of the autonomous compartment-capsule are made interfaced and with the possibility of their forced (automatic or mechanical) closure and water resistance. Between the autonomous compartment-capsule and the fuselage body are placed shock-absorbing devices and materials. Devices that ensure the separation (cutting) of the parts of the helicopter body from an autonomous compartment-capsule are made with the possibility of using the cumulative effect and / or the effect of a directed explosion. The self-contained compartment capsule contains a parachute system (patent RU No. 2213027, B64C 27/04, B64C 1/32, B64D 25/12, publ. 2003.09.27).

The disadvantages of such a helicopter include a very complex and dangerous construction due to the need for a huge amount of explosives.

The objective of the utility model is to simplify the design and reduce the danger of use by reducing the number of locations of explosives.

This goal is achieved by the fact that in a known helicopter containing a propeller with blades and a fuselage, consisting of the bow with the cockpit, the central and tail parts, where the passenger compartment is located in the central part in the form of a sealed autonomous compartment equipped with a parachute, made with the possibility of separation from the bow with the cockpit and the tail, the new thing is that the sealed autonomous compartment is attached directly to the tail boom connecting the bow with the cockpit and the tail st, and as a means of separating the sealed autonomous compartment, there are special explosive fastening bolts - known as “pyro bolts”.

Figure 1 shows a schematic representation of the inventive helicopter, side view; figure 2 is a mounting element of the cabin, figure 3 is the same, in section.

The helicopter contains a fuselage 1 and a propeller with blades (not shown). The fuselage 1 consists of a bow 2 with a cockpit, a central 3 and a tail 4 parts, in the central part there is a passenger cabin in the form of a sealed autonomous compartment 5 equipped with a parachute (not shown), while the sealed autonomous compartment 5 is attached directly to the tail boom 6 connecting the nose part 2 with the cockpit and the tail part 4, and as means for separating the sealed autonomous compartment 5 there are special explosive fastening bolts - “pyro bolts” 7, which have a weakened cross-section at the installation site 7 and 8. The bolts when the nut 9 is connected a fork 10 integral with beam 6, the tail section 4 and the lug 11 belonging to the sealed compartment 5 autonomous.

The device operates as follows. When there is a threat of a helicopter crash, the charges of 8 pyro-bolts 7 are undermined, while the halves of each bolt 7 fly out of the holes of the plug 10 in different directions, releasing the pair of “ear-plug” fastenings of the sealed autonomous compartment 5. Then the parachute is discharged, which, when disclosure pulls sealed autonomous compartment 5 from the fuselage structure and smoothly lowers it to the ground.

Such a design is much simpler than the known ones and provides a reduction in the danger of use by reducing the number of explosive locations.
