The workplace of the crew member in the cockpit

 

(57) Abstract:

The invention relates to equipment jobs crew members or passengers of the aircraft and can be used in both aviation and automotive industry, shipbuilding, building, and so on workplace crew member in the cockpit includes protruding above cabin floor support for the installation of chairs and piping system of air heating. Support for the installation of a chair provided with a casing made of sound-absorbing material, which is closed under the piping system of air heating work place, on the walls of the housing are made of the exit port of the air flow, and the floor of the cab, under the hood is covered with sound-absorbing carpet material, forming the camera noise absorbing system of air heating. The technical result is the creation of a workplace, a crew member in the cockpit required a comfortable working environment through effective system combining uniform air heating jobs crew members while reducing noise from the incoming air from the system air heating. 6 Il.

The present invention relates to equipment jobs crew members or passageiro etc.

Known seats for crew or passenger seats installed on poles or on the grounds, towering above the floor of the aircraft cabin, for example: A. with. 1079547, CL 64 D 11/06 for 1982; U.S. patent 4674713, CL 64 D 11/06; the United Kingdom patent 884266 for 1962.

However, a common disadvantage of these known solutions is the lack of devices for uniform circular heating jobs of the crew and passenger seats.

Known heating and ventilation cabins of airplanes and helicopters, and see.with. 164803, CL 64 D 13/08 for 1963., in which warm mixed air pipeline is displayed in the cockpit on the windshield of the lamp to the feet of pilots and individual blowout passengers.

This system provides heating, but does not create a uniform distribution of warm air around the jobs of the members of the crew and passenger seats.

Also known in the air conditioning system, see Shulzhenko M. The design of the aircraft, ed. 3rd, revised and enlarged, published in"engineering", 1971. p. 220, Fig.4.45 and page 219, in which the warm air under pressure noise is fed into the cabin through pipelines located along the sides of the cab.

P is Shagirov and crew members, but makes a noise, but in the supply system of warm air no silencers.

The objective of the proposed invention is the provision in an aircraft required comfortable working conditions of crew members through the creation of an effective system combining uniform air heating jobs crew members while reducing noise from the incoming warm air.

This object is achieved in that in the proposed device, comprising protruding above cabin floor support for the installation of chairs and piping system for air heating of the workplace, support for the installation of a chair provided with a casing made of sound-absorbing material, which is closed under the piping system of air heating work place, on the walls of the housing are made openings for exit of warm air stream. In this case, the floor of the cab, under the hood is equipped with sound-absorbing carpet material, forming the camera noise absorbing system of air heating.

In comparison with the known technical solutions proposed is significantly different because:

- create the necessary comfortable working conditions by ensuring uniform distribution of warm vassenka casing;

the casing serves a decorative and protective functions, covering design supports;

- casing made of sound-absorbing material, and the floor under the bonnet covered with sound-absorbing material, which gives the device the functions of a silencer air heating system.

Thus, the present invention meets the condition of inventive step.

The invention is illustrated by drawings, where:

- Fig. 1 shows a General view of the workplace, a crew member in the cockpit;

- Fig. 2 is a rear view;

- Fig. 3 is a top view;

- Fig. 4 - cross section a-a of Fig. 1;

- Fig. 5 - section b-b of Fig. 3;

- Fig. 6 - section b-B of Fig. 1.

Workplace crew member consists of chair 1 and supports the installation of chair 1, including rails 2 connected to the vertical posts 3, resting on the floor 4 cabins, and transverse horizontal profiles 5 fastened together by bolts, closed by a cover 6 made of absorbent material, such as fiberglass, and having a horizontal surface 7, side walls 8, and the front 9 and rear 10 wall. Side 8, the front 9 and rear 10 of the wall of the casing 6 provided with holes 11 for output warm the heating of the workplace. Holes 11 for the output of warm air supplied visors 13 for deflecting the air stream and protection against ingress of random small items into the internal cavity of the casing. The cockpit floor 4 under the hood covered with sound-absorbing carpet material 14, such as pile aviation carpet Avimo-1". The lower edge of the casing wall around the perimeter edged rubber sealing profile 15, which prevents the release of air near the floor.

The device operates as follows.

Warm air coming from the pipe 12, the air heated workplace, fills the interior space under the bonnet 6, heats the horizontal surface 7 of the casing 6 and the through holes 11 in the walls 8, 9 and 10 of the casing 6 extends into the space surrounding the workplace, a crew member is uniformly heated him from all sides.

Passing from the pipe 12 through the internal cavity of the casing 6 to holes 11, the noise from the heating system significantly suppressed absorbent material of the casing 6 and the floor surface 4 under the casing 6, and fades out in the maze formed by the elements 2, 3 and 5 of the supports of the chair 1.

Thus, in the workplace crewmen are required comfort conditions servant who ENES crew while reducing noise from the incoming air from the heating system.

The workplace of the crew member in the cockpit, including protruding above cabin floor support for the installation of chairs and piping system of air heating workplace, characterized in that the support for the installation of a chair provided with a casing made of sound-absorbing material, which is closed under the piping system of air heating workplace, and on the walls of the housing are made openings for exit of the air flow while the cockpit floor under the bonnet is covered with sound-absorbing carpet material, forming the camera noise absorbing system of air heating.
