Abstract

FIELD: aircraft manufacture; methods of saving aircraft people at hopeless emergency situation.

SUBSTANCE: proposed method is based on use of parachutes for three- or four-seat blocks which are first closed with metal cases, after which breathing air is automatically fed. Then, aircraft is divided into sections by means of shaped charges in definite succession: first nose, fuselage, wings and tail are separated; then roof is separated and seat blocks with people are separated last.

EFFECT: extended technological capabilities of saving aircraft crew and passengers in an emergency.

Description

The invention relates to methods for saving aircraft people and can be used to create new systems for such rescue.

There is a known method of rescuing aircraft passengers according to the application No. 2005101031, which consists in the use of parachutes, and in the manufacture of the aircraft it is equipped with three autonomous self-firing, firing parachute systems for the tail, middle and bow parts, as well as cumulative explosive devices for these parts and for wings, moreover, in a hopeless emergency, they trigger cumulative explosive devices and divide the aircraft into three indicated parts and simultaneously a similar cumulative explosive The wings separate the wing system and simultaneously activate the parachute systems of the tail, middle and bow of the aircraft.

This method of salvation makes it possible to save people, but this possibility is still insufficient, and the death of some people is not excluded.

The objective of the invention is to maximize the ability to save all people on the plane.

The task is achieved by the fact that in the manufacture of the aircraft it is equipped with several self-contained self-propelled shooting parachute systems installed on blocks of seats of 3 or 4 pieces at a time, while the blocks of seats are equipped with self-contained self-closing cases when flying the open front of the seats, and these cases are metal and are closed ensuring the tightness of the formed space, and the chairs are stocked with compressed air for breathing for 2-3 hours, the capacity of which is equipped with automatic devices valve for supplying air to the chair immediately after closing the case, each block of seats being buoyant when hit by water, and the center of gravity of the block of seats is below the mid-height of the chairs, which is the golden section (i.e. 1,618 m), while the separation the aircraft in the air is carried out in a certain sequence: first, large parts - the fuselage, wings and tail, are separated, and after a while the parts are separated from the parts where people are located, and the blocks of the armchair are finally separated with humans, each unit is provided with an automatic device for separating the body from the seating unit (after landing), which during the descent is blocked against accidental activation, and after the shutter is automatically unlocked, and illuminates the inscription "can separate housing", and a button is provided with a green light.

New significant features of the method:

- in the manufacture of the aircraft it is equipped with several self-contained self-firing shooting parachute systems installed on blocks of seats for 3 or 4 pieces at once,

- the blocks of chairs are equipped with self-contained self-closing bodies when flying the open front, and these bodies are metal and are closed to ensure the tightness of the resulting space,

- the chairs are supplied with a supply of compressed air for 2-3 hours, the capacity of which is equipped with an automatic valve for supplying air to the chair space immediately after closing the case,

- the armchair block is provided buoyancy when it enters the water, and the center of gravity of the armchair block is below the mid-height of the armchairs, which is the golden ratio (i.e. 1,618 m),

- the separation of the aircraft in the air is carried out in a certain sequence: first, large parts - the nose, fuselage, wings and tail are separated, after a few moments the roof is separated from the parts with people there, and lastly the blocks of chairs with people are separated,

- each block of seats is equipped with an automatic device for separating the body from the seats (after landing), which is blocked during the descent and automatically unlocked after the descent, and the inscription "you can separate the body" lights up, and the button is equipped with a green light.

The listed new essential features, together with the known ones, are necessary and sufficient to achieve a technical result in all cases to which the requested amount of legal protection applies.

The technical result is achieved due to the fact that:

- in the manufacture of the aircraft, it is equipped with several self-contained self-firing shooting parachute systems installed on the seat blocks of 3 or 4 pieces, firstly, for a more rational distribution of loads, and secondly, to assist a friend in case of emergency situations,

- the chair units are provided with self-contained self-closing bodies during the flight of the open front end, and these bodies are metal and are closed to ensure the tightness of the resulting space to preserve the living conditions of people,

- the chairs are supplied with a supply of compressed air for 2-3 hours, the capacity of which is equipped with an automatic valve for supplying air to the chair space immediately after closing the case to ensure breathing of people without their participation,

- the armchair unit is provided buoyancy when it enters the water, and the center of gravity of the armchair unit is below the mid-height of the armchair, which is the golden ratio (i.e. 1.618 m) to streamline the design and increase the likelihood of survival even when it gets into the water,

- the separation of the aircraft in the air is carried out in a certain sequence: first, large parts - the nose, fuselage, wings and tail are separated, after a few moments the roof is separated from the parts with people there and the blocks of seats with people are last separated to prevent accidental collisions of parts of the plane during the flying time of these parts,

- each block of seats is equipped with an automatic device for separating the body from the seats (after landing), which is blocked during the descent, and automatically released after the descent to prevent accidental activation of the mechanism during descent in the air, and the lightening of the inscription “you can separate the body” gives the person information, providing the button with a green light makes it easier to find.

Consider an example implementation of the method. Suppose that during the flight a situation arose (as on TU-144. Anapa flight), when the plane fell into a tailspin and no actions of the crew give a result, then at a critical altitude of 3-3.5 thousand meters either automatically or by force the decision of the commander the proposed emergency rescue system is switched on: first large parts of the aircraft are separated: the nose, fuselage, wings and tail, and then the roof is separated from the parts where people are located, and then the blocks of seats with parachute systems are separated. Moreover, the closure of the blocks of armchairs takes place in advance, and immediately after the closure of the enclosure, breathing air is automatically turned on, and after landing, the mechanism for separating the hulls from the blocks of armchairs also automatically unlocks, and the self-separation of the hulls occurs after one of the saved and understands what needs to be done - press the button to separate the case from the seat unit. This is the only action required of the saved people. However, all this will be known to all passengers in advance from the relevant instructions before the flight, and it will not be difficult to do this, since out of three or four people who are in the block, someone will keep their sanity and do it. This is one of the reasons for parachuting not every chair, but in blocks of 3 or 4 pieces at once.
