Description

The proposed utility model relates to aircraft, namely, to the structural device of the power plant of the aircraft.

Modern aircraft such as gyroplane are becoming more and more popular due to their unique capabilities.

Modern gyroplanes are equipped mainly with one engine, which drives a free propelling propulsion propeller type. Having high flight safety characteristics, gyroplanes with one engine, however, can fall into emergency situations with the need for emergency landing. And if, at the time of emergency landing, the gyroplane is located above a dangerous underlying surface (water, forest, mountains, etc.), the probability of a successful landing is very small.

The proposed device - the power plant gyro-is designed to solve this problem.

The disadvantage of this device is the lack of reliability of the aircraft.

Closest to the claimed utility model is US patent No. 2954186, IPC ВСС 27/02, "Autogyro with coordinated control." The invention relates to aircraft, and in particular to gyroplanes. A coordinated gyroplane contains: a rotor, a frame, control wheels, a power plant consisting of an engine and a propeller, the engine mounted on the engine frame behind the pylon.

The disadvantage of this technical solution is the lack of reliability of the gyroplane.

The technical task of the proposed utility model is to create a reliable propulsion system of a gyroplane.

The technical result, the creation of a reliable propulsion system of the gyroplane, is achieved due to the fact that the propulsion system of the gyroplane contains: two pushing screws, two engines, a pylon, a coaxial shaft of the pushing screws, a frame for

engine installation and spinal beam. Engines are located on the frame mirror in relation to each other. The pushing screws are coaxial and located on the coaxial shaft. The external shaft is supported on the internal shaft through a series of thrust bearings. The first screw is located on the outer shaft and the second screw on the inner shaft. The shafts of the pushing screws are connected to the pylon through a shaft mount, which has a thrust bearing and a ball joint. The transmission of motion from the engines to the shafts is in the form of a belt drive, where the first engine transmits the motion to the internal shaft, and the second engine to the external shaft. The frame for installing engines is mounted on the spinal beam of the gyroplane through a mounting unit with shock absorbers with the possibility of changing the angle of inclination of the frame. The outer shaft is additionally supported by the spinal beam by means of a support beam with a support bearing located on the external shaft.

The essence of the utility model is illustrated by drawings:

FIG. 1. - Schematic representation of the power plant gyro.

FIG. 2. - Schematic representation of the power plant gyro with a modified angle of inclination of the frame for installing engines.

FIG. 3. - Schematic illustration of a special unit for fixing the system of coaxial screws to the pylon.

The power plant of the gyroplane 1 contains: two pushing screws 2, two engines 3, a pylon 4, a coaxial shaft 5 of the pushing screws 2, a frame for installing engines 6 and a spine beam 7.

Engines 3 are located on the frame 6 in a mirror with respect to each other. The frame for installing engines 6 is mounted on the spinal beam 7 of the gyroplane by means of a mounting unit with shock absorbers 8 with the possibility of changing the angle of inclination 9 of the frame. (see Fig. 1, 2)

The pushing screws 2 are coaxial and located on the coaxial shaft 5. The support of the outer shaft 10 on the inner shaft 11 is made through a series of thrust bearings 12. The first screw 13 is located on the outer shaft 10, and the second screw 14 on the inner shaft 11. Pushing shafts 10, 11 the screws 2 are connected to the pylon 4 through the shaft mount 15, which has a thrust bearing 16 and a ball joint 17. The transmission of movement from the engines 3 to the shafts 10, 11 is made in the form of a belt drive 18, where the first engine 19 transmits the movement to the inner shaft 11 and the second engine is 20 in eshnemu shaft 10. The outer shaft 10 is further supported by the center sill 7 of the base beam 21 with ball bearing 22 disposed on the outer shaft 10. (see. Figs. 1, 2, 3)

The device operates as follows:

1. On the ground establish the optimum angle of inclination of the frame for installing engines 6.

2. Start the engines 3.

3. Engines 3 through a belt drive 18 transmit the motion to the coaxial shaft 5.

4. The coaxial shaft 5, in turn, transmit the movement to the pushing screws 2.

5. The pushing screws 2 move the aircraft forward.

6. If one of the engines 3 fails, the aircraft safely continues the flight and lands in the operating mode.

7. If it is necessary to save fuel to increase the flight range, the pilot turns off one of the engines 3 of the power plant of the gyroplane 1 and the aircraft continues to fly until it is necessary to switch to the second engine 3, and then makes a landing in the operating mode.

Maintenance of the power plant gyro:

All components of the power plant gyro are the easiest to maintain. The use of the multi-V-transmission proposed for this device allows the use of aluminum alloys. And aluminum alloys make it possible to abandon gears, and, accordingly, from lubrication and cooling, and these alloys have effective heat-removing properties (not applicable to engines).

The proposed power plant gyro 1 significantly improves flight safety, through the use of a twin-engine power plant system.

In the proposed propulsion system of the gyroplane 1, each of the two engines 3 drives its own pushing screw 2, while each engine 3 (19, 20) has its own system that ensures the independent operation of engine 3 (19, 20).

The proposed layout of the power plant gyro 1 allows for failure or deliberate shutdown of any of the engines 19, 20 effectively (independently) to work another

engine 19 or 20 and continue to fly normally, and avoid an emergency landing.

This feature of the power plant allows you to double the reliability of the aircraft, as well as save fuel and increase flight duration.

The proposed power unit gyroplane 1 is compact and lightweight, while allowing you to get the highest possible efficiency due to the fact that the engines 3 and pushing screws 2, combined by a common coaxial shaft 5 (one in the other), and each engine 19 or 20 drives its own screw 13, 14. Moreover, the engines 19 or 20 are rigidly mounted on one frame for installing engines 6. Coaxial screws 2 can increase traction and efficiency by more than 10% due to the fact that the entire thrust of both screws 2 in the proposed power plant perceives a common support - resistant under the dogrose 16, which is part of the attachment point 15 of the shafts. The total weight of the power plant gyro 1, compared with power plants with spaced engines and propellers, becomes 40-50% less.

The combination of coaxial screws 2 with a coaxial shaft 5 makes piloting much easier, since when changing the position of the gyroplane in space the gyroscopic moments are not transmitted to the fuselage (the gyroscopic moments are zeroed during folding).

The mounting unit 15 of the shafts, through which the shafts 2 are attached to the pylon 4, comprises: a thrust bearing 16 with a housing, two threaded nuts for mounting the external and internal cages, a ball joint 17 consisting of a spherical bearing

a housing with a threaded fastening nut, as well as a retaining ring for fixing a spherical bearing. The retaining ring to a large extent avoids thermal deformation of the shafts 2.

In order to avoid loading the coaxial shaft 5 with bending moments from inertial and aerodynamic forces, the shaft mount 15, which connects the coaxial shaft 5 and the pylon 4, has a thrust bearing 16 and a ball joint 17. The outer shaft 10 is supported on the inner shaft 11 through the supporting bearings 12 to control the deformation of the shafts 10, 11.

Rigid installation of engines 3 on a frame for installing engines 6 and the arrangement of engines 3 are mirrored, with the output shafts turned to each other, provides a significant reduction in vibration while both engines 19, 20 are operating at the same time. The remaining, insignificant level of vibration is effectively suppressed by the fact that the frame for installation of engines 6 is combined with the spinal beam 7 of the gyroplane through the attachment point with a shock absorber 8. This greatly increases flight comfort.

For belt drive 18 from the engine 19 or 20 to the coaxial shaft 5, multi-ribbed belts can be used, which makes it possible to effectively damp torque pulsations

The noise from the multi-V-transmission is practically absent. V-ribbed torque transmission is characterized by simplicity in the selection of the reduction coefficient, efficiency in production and operation.
