Abstract

FIELD: aircraft.

SUBSTANCE: disadvantages of known aircraft are the destruction of the hull when falling, resulting in the death of people. During air crashes, the passengers die from the destruction of the hull, receiving injuries incompatible with life: from sharp fragments of the metal hull, from crumpling the hull and pinching passengers with the hull, from impacts on the hull, from falling from a height outside the aircraft after the destruction of the hull. If the integrity of the hull is maintained, the passengers will only experience short-term heavy overloads at the moment of collision with the ground. A person tolerates short-term overloads of more than 100 G. The survival of the passengers and the pilots depends entirely on the integrity of the hull.

EFFECT: invention makes it possible to preserve the integrity of the hull in a collision with the ground during an air crash, thereby preventing the death of people.

Description

The invention relates to aircraft construction, namely to the creation of an aircraft capable of maintaining the integrity of the body in a collision with the ground during a plane crash and save the lives of passengers and crew. The disadvantages of the device, known aircraft, is the fragility of the hull and its destruction, as a result of a collision with the ground, which leads to the death of people.

During air crashes, passengers die as a result of the destruction of the hull, receiving injuries incompatible with life: sharp fragments of the metal hull, from crushing the hull and trapping passengers by the hull, from impacts on the hull, from falling from a height outside the aircraft, after the destruction of the hull in the air. While maintaining the integrity of the hull and excluding contacts with the hull, passengers will experience only short-term large overloads at the moment of collision with the ground. A person can endure short-term overloads of more than 100 G. The survival of passengers and pilots depends entirely on the integrity of the hull.

The object of the claimed invention is to maintain the integrity of the aircraft body in a collision with the ground during a plane crash. This will eliminate the death of people.

The device of an aircraft with a high degree of safety, differs in that, the entire body of the aircraft and its wings are made of a three-layer material which consists of two outer layers and one inner layer (see Fig. 1, 2), the outer layers-1 are made of composite materials, for example carbon sheets, and the inner layer-2 consists of a honeycomb structure of carbon or Kevlar, this honeycomb structure is monolithically connected to the outer layers, and its honeycomb cells are filled with elastic polystyrene foam, this three-layer material has a monolithic structure and does not breaks, and the hull can be deflected, the entire aircraft body is created as a monolithic structure, the body must maintain integrity in a collision with the ground, in the event of a plane crash, a strong frame is installed inside the aircraft - 4, made of carbon or titanium channels and rails, which retains the shape of the body, preserve the integrity of the body will allow: the rounded shape of the body in the form of an egg, a strong internal frame - 4, and a new three Loy material, the use of composite materials of carbon fiber and Kevlar, will also lighten the entire aircraft, thereby weaken the load on the body in a collision with the ground and reduce fuel consumption, the back of the seats - 6, the crew and passengers should be higher than the head sitting in it and withstand the load impact on the ground, passenger seats and pilot seats, with their strength and their protective shields - 3, create a safe zone for the person sitting in it and in the event of a disaster, protect the person sitting in it from damage to the hull and foreign objects, even if there is a strong deflection of the hull (cm. FIG. - 2), then the back of the seat - 6 leaning against the ceiling will not allow you to press down, and the side flaps - 3, will not allow you to hit the body and other foreign objects sitting in them, at the time of the plane crash, the passenger must be fixed in his seat with a special emergency with a seat belt - 8, a person can withstand short-term overloads of more than 100 G, therefore, in a collision with the ground, passengers and crew will not die if the above invention is correctly applied.

The essence of the invention is illustrated by drawings:

fig. - 1. - The device of an aircraft with a high degree of safety, (diagram),

fig. - 2 - Possible damage in a frontal collision, (diagram).

FIG. - 3. - Special safety seat, (diagram).

1. - outer layers, composite materials, carbon sheets; 2. - inner polystyrene layer; 3. - protective shields; 4. - inner frame; 5. - luggage compartment; 6. - strong backrest; 7. - possible damage in a head-on collision (indicated by a dotted line); 8 - emergency seat belt; 9 - carbon fiber seat belt shield.

The device of an aircraft with a high degree of safety (see Fig. - 1, 2, 3.) is carried out as follows: in the event of an emergency landing, passengers are fastened with emergency seat belts - 8 and covered with protective shields - 3 with which the seats are equipped. The pilots turn off the engines if they are still running, and put the plane on a glide flight to slow down. And they are looking for a flat, clean piece of land for an emergency landing. Whenever possible, pilots try to avoid a head-on collision with the ground, and try to land the plane on the "belly" to slide on the ground and reduce overloads. With a smooth landing on the "belly", the carbon body will not collapse, as the metal body collapses, and will not dig into the ground, as the metal body digs in, but will slide along the ground until it comes to a complete, smooth stop. There may be minor damage to the hull, tree branches or on the building, if a flat place is not found for an emergency landing, but in general the hull should not be damaged. And in a head-on collision with the ground, there may be significant deflections of the body (see Fig. - 2), in this case, passengers and crew will be protected by strong seats - 6, with protective shields - 3.

Claims (1)

An aircraft with an increased degree of safety is characterized by the fact that the entire body of the aircraft and its wings are made of a three-layer material, which consists of two outer layers and one inner layer, the outer layers are made of composite materials, for example, carbon sheets, and the inner one consists of a honeycomb structure of carbon or Kevlar , moreover, this honeycomb structure is monolithically connected to the outer layers, and its honeycomb cells are filled with elastic polystyrene foam formed under increased pressure, the entire aircraft body is made of a monolithic structure, a strong frame of carbon or titanium channels and rails is installed inside the aircraft, and the backrests of the crew seats and passengers are made above the head of the person sitting in it and withstand the load of impact on the ground, all seats are equipped with emergency seat belts.
