Description

The utility model relates to aircraft and can be used in the construction of aircraft, in particular, helicopters.

Known cargo cabin of the aircraft, containing the floor, two sidewalls, door leaves, covering the rear opening of the cockpit. The cabin is equipped with folding tubular seats located on the sides on the right and left sides, a hatch for lifting or lowering people and / or goods, made in the bottom of the cabin.

On the outer surface of the sidewalls there are handles.

The sides include an aluminum frame, consisting of frames and stringers, to which the casing is attached. In places of installation of seat attachment points, the sidewall frame has amplifications. Each sidewall has glazed organic glass windows. The cutout in the sidewalls under the windows is reinforced with a common sheet edging.

The cab floor is made in the form of a honeycomb panel.

On the floor panel there are several longitudinally arranged profiles that serve as stops for the seats, facilitate the movement of goods during loading / unloading and serve as mooring units for cargo to the floor.

Each door leaf is made in the form of a frame and paneling and is hinged to the nodes of the side panels of the cab. In order to avoid skewing the flaps when they are closed, there are guide grooves on the cab, which, when closing the door, include L-shaped guide clamps fixed to the upper edge of each leaf. At the lower end of each leaf there are guide pins that fit into sockets made on the floor surface. Sashes can be equipped with a locking device for fixing them in the open position. For ventilation of the cabin in one or more leaves, shutters with adjustable position of the lattice elements can be made.

There are locks on the door leaves for locking and latches for holding the leaves in the closed position.

(see G.I. Ioffe et al. “Helicopter Cl 26”, Moscow, “Transport”, 1982, pp. 154-156) is the closest analogue.

As a result of the analysis of the known cab structure, it should be noted that it has a rather large mass, low rigidity and heat and sound insulation properties, as well as a large number of parts, which increases the complexity and cost of its manufacture.

Opening the door leaves by rotation relative to the vertical axis requires their mandatory fixation in the open position with the help of additional devices and a rather complicated mechanism for their fixation in the closed position.

Loading / unloading goods and boarding / disembarking passengers through the rear hatch of the cab is not always convenient. In addition, the presence of only the rear flaps narrows the scope of the aircraft, preventing it from performing a number of important tasks, for example, performing rescue operations using a cargo winch, etc.

The objective of this utility model is to develop a design of a cargo-passenger cabin of an aircraft, light and durable, with wide functional capabilities, which allows convenient and quick loading / unloading of goods or passengers and, if necessary, provide emergency evacuation of passengers.

The task is ensured by the fact that in the cargo-passenger cabin of the aircraft, containing two side panels forming the cabin cabin and a floor panel with a hatch, a closed lid and profiles for moving and mooring cargo, sash closing the rear cockpit opening, windows made in the side panels, places for installing seats and elements for fixing the cockpit to the aircraft, it is new that the cockpit is equipped with a top panel and a front panel with an aperture for passage of the crew or maintenance personnel, an aperture, filled in at least one of the side panels and the door closing it, installed with the possibility of plane-parallel movement along the guides mounted on the outer side of the side panel, one of the wings closing the rear opening of the cab is mounted to rotate relative to the horizontal axis on the upper panel and the other on the floor panel, while in the cab there are places for installing a stretcher, and the cab

made in the form of at least one three-layer panel with sheathing of polymer composite materials and a honeycomb placed between them, on the side panels there are windows for emergency evacuation, and places for installing the stretcher are made on the top panel and the floor panel, while on the front panels have seats for seats, the door and rear doors are equipped with devices for signaling their closure, and attachment points for additional equipment are installed on the top panel
