Description

Usage: in the field of aviation technology. The invention:

1. Jumping gyroplane containing a main rotor with a sleeve that allows you to change the overall pitch of the blades, the main rotor spinning system, a propulsion system with a propeller, a longitudinal beam, a vertical pylon, plumage, landing gear and pilot seat, characterized in that it is made using easily detachable or folding and stacking in a special container designed for storage and transportation of the device:

- removable propeller blades, vertical tail mounts, landing gear;

- pivotally connected to the pylon of the longitudinal beam with the possibility of reducing the angle between it and the pylon to zero degrees;

- folding in the vertical plane of the horizontal tail and the pilot's seat;

2. Autogyro according to claim 1, characterized in that the container is collapsible and in flight is placed behind the pilot's seat.

Known folding helicopter (http://twistairclub.narod.ru/ka56/) the helicopter is made according to the "folding angle" scheme, is equipped with an engine, the solutions of the nodes of the folding elements of the helicopter are made according to the scheme of single-moving kinematic pairs, and such pairs that provided the folding process or deployment of the helicopter in operational condition by helicopter only six. Detachable structural elements are only 4 blades of the coaxial rotor. The time taken to bring a helicopter from a transport position to an operational one by less than 10 minutes

Disadvantages:

It belongs to another class of aircraft and has an insufficient flight range, a high-power engine, high fuel consumption.

(RU 5050052/23; 1992.06.30)

The dimensions of the apparatus are reduced during transportation and storage, which simplifies them and reduces the cost of operation. Regulation foreseen

Alignment allows you to expand the range of functions of the gyroplane in operation. The autogyro has a fuselage in the form of a pipe, a central vertical strut also in the form of a pipe of the same cross section as the fuselage pipe. The central knitz is rigidly connected to the rack, with the fuselage tube and the pilot's seat. Chassis - tricycle with nose support. The power plant consists of an engine and a propeller. The tail of the normal circuit.

An additional strut is pivotally connected to the strut at one end and pivotally connected to the boot of the rotor hinge at the other end. The main and additional struts are made of adjustable length. The screw is placed in the boot on an axis oriented along the longitudinal axis of the gyroplane with the possibility of deviation relative to it. The control wiring connects the supporting system with the screw, control handle and provides control of the deviation of the screw in the roll channel from the handle. In a gyroplane, its transformation into a parking configuration is provided by certain folding and fixing of the blades and screw, as well as the possibility of adjusting its centering by changing the length of the main and additional struts.

Disadvantages: It does not allow the use of a helipad for take-off and landing, and this design does not allow a significant reduction in size, which in turn greatly complicates the transportation and storage of this aircraft.

As a prototype we use a gyroplane-moped (RU 2007103214/22; 01/19/2007)

Autogyro-moped, containing a propulsion system with a pushing screw, a rotor with a sleeve that allows you to change the overall pitch of the blades, with a rotor spinning system, the seat and chassis are made in the form of a bicycle, the rear sleeve of the bicycle is connected to the motor shaft, to the engine located behind the seat two landing gears are attached to the pilot, which serve as two additional support points.

Before takeoff, the pilot connects the NV blades to the HB sleeve, connects the pushing rotor blades to the pushing rotor hub, sits down on the bicycle, occupying the flight position, starts the engine, sets the zero pitch of the main rotor blades, turns on the HB spin.

To translate into a ground vehicle position, the pilot disconnects the HB blades and puts them in special mounts under the bicycle frame, similarly goes with the propeller blades,

removes additional supports and switches the engine to rotation of the rear wheel hub of the bicycle.

Disadvantages:

Takes up a lot of storage space.

Figure 1 shows a jumping folding gyroplane.

The icon indicated by 11 in FIG. 1 indicates kinematic pairs. First, the elements of a jumping folding gyroplane are taken out of the container. Then, the wheels 10 are removed from the container and installed on the main frame (consisting of elements 1, 3, 4 - of the power plant, 5 - of the pilot's seat), which is laid on its side, after which the longitudinal beam 9 leans forward and the pylon 3 unfolds to the sleeve 1, the rotor blades 2 are unfolded and attached. After performing these actions, the assembled frame is raised to a vertical position and mounted on the chassis (including 9, 10), then the blades 7 are attached to the pusher screw 8, after which it is unfolded and attached vostovoe feathering 6. Thereafter the container 6 is resolved into flat parts, which are fixed at the back of the pilot seat.

Before takeoff, the pilot takes a flight position, starts the engine, sets the zero common pitch of the rotor blades, includes the promotion of HB. After reaching the necessary take-off revolutions, the total HB step increases to take-off, the engine switches to the promotion of the pushing screw and the ascent begins. A jumping folding gyroplane, rising upward, simultaneously begins to gain horizontal speed. After the jump is completed, the NV is put into autorotation mode. At this take-off is completed, the flight is performed in autogyro mode.

To perform a soft landing without a run for one or two meters from the ground, the pilot increases the angle of attack of the blades to the maximum and the kinetic energy of the rapidly decreasing apparatus is extinguished, the machine freezes for a moment in the air, after which the landing is very soft, without hitting the ground.

To transfer to the ground transportation position, the pilot carries out the assembly process of the jumping folding gyroplane, which is carried out in the reverse order to the folding process. The result is the container depicted in figure 2.
