Description

Helicopter external suspension for mooring an unmanned aircraft

The inventive utility model relates to air transport and is intended to ensure the launch and landing of unmanned aircraft in places where there are no airfields.

Numerous types of active and experimental catapults or take-off ramps are known that provide the launch of unmanned aircraft in the absence of airfields. However, the landing of these aircraft, as a rule, is carried out with the help of a parachute or not at all if the aircraft is of a single use, for example, a cruise missile. (EI Ruzhitsky “Bezaerodromnaya Aviation”, p. 53, Oborongiz, 1959) - [1].

Known trolley with ramp for the aircraft Ryan X-13. ([1] - p. 150-152, Fig. 134, 135). With the ability to fly in an upright position, the X-13 aircraft takes off and lands with the help of a mooring ramp, to which it is moored, clinging with a hook to the tensioned cable of the towing device on the ramp.

Helicopter external suspensions are known, equipped with a hook or a lock at the end of the suspension power rope, for which the load is hooked and then transported by air. The external helicopter suspension can be used as a berthing device for launching an unmanned aircraft raised to a height, as well as for landing it, if the end of the external suspension power cable is equipped with a coupling unit for mooring mooring unmanned aircraft.

The prototype of the proposed utility model adopted cargo suspension (patent No.2002677, MGZH V64D 9/00, V64D 17/22, publ. BI No. 41-42, 1993), containing a power rope, slings with attachment points to the fuselage, electromechanical locks top for emergency release of the power cable and the lower one for tactical discharge of cargo, swivel current collector and electric lock control system.

Such a suspension, having an electromechanical lock or just a hook at the end of the power cable, cannot be used to engage and disengage with an unmanned aircraft in flight.

The technical result, which is achieved by the claimed utility model, is to expand the possibility of its application by equipping a helicopter external suspension with a clutch assembly, to which a flying unmanned aircraft is moored for landing on a helicopter, and an airplane standing on the ground is moored for take-off on a helicopter.

The technical result is achieved by the fact that in the device of the external helicopter suspension for mooring an unmanned aircraft containing a power cable, the upper attachment point to the fuselage of the helicopter and the lower node on the power cable, new is that the lower node is a clutch assembly for mooring an unmanned aircraft, consisting from a triangular loop with an elastic rope at the base, the ends of which are sealed together with elastic tips at the ends of two side rods, the other ends of which are pivotally connected to the body, i a curling apex of the loop and on which a spring is installed, which ensures the tension of the power cable by extending the rods to the sides, in addition, a rod is pivotally attached to the body, connecting the loop articulated with its other end to the power cable to moor the flying unmanned aircraft, providing landing, as well as its take-off land by helicopter.

The essence of the utility model is illustrated in FIG. 1 - FIG. 3, where:

FIG. 1 - Helicopter with external suspension in the process of coupling with an unmanned aircraft.

In FIG. 1 shows a helicopter 1 with an external suspension device in flight and an unmanned aircraft 2, which are in the process of mooring (gearing). In FIG. 2 shows the clutch assembly of the external suspension, mounted on the end of the power cable 3 (type B, FIG. 1), consisting of a rod 4, a housing 5, rods 6, the ends of which are sealed with the ends of a polyamide rope 7. The rods 6 under the action of a leaf spring 9, can rotate around the bolts securing their eyes to the housing 5. To increase the bending radius of the rope 7 when it is tensioned by the spring 9, elastic tips 8 are installed at the exit from the rods 6 to the rope and rods. FIG. 3 shows the beginning of the in-flight clutch process in flight of the external suspension loop and the aircraft clutch assembly (A, Fig. 1), consisting of a hook 11 mounted on the pylon 10. A camera 12 is placed in the hook body 11. The rod 4 is suspended at an upper point towards the end rope 3, in flight under the influence of its weight and the weight of the body 5 is always in a vertical plane and orientes the plane of the triangular loop perpendicular to this plane, and the aerodynamic drag forces of the rods 6 and rope 7 create its inclination to the horizontal plane. The triangular shape of the coupling unit ensures a stable position of the loop in flight due to the swept position of the side rods, providing directional stability similar to the stability that is created by the swept wings of an airplane. In the helicopter hover mode, the rod and the loop plane are in the vertical plane.

The technology of using the inventive helicopter external suspension device for mooring an unmanned aircraft is as follows:

From above, on the fuselage of the unmanned aircraft 2, a pylon 10 with a hook 11 should be installed above the center of mass along the axis of mass. The helicopter 1, in addition to the external suspension 3, may also contain an equipped place for an operator controlling the unmanned aircraft using an automatic control system transceiver (automatic control system).

Before starting, the unmanned aircraft 2 and the external suspension rope 3 should be located on the platform in front of the left side of the helicopter from the side of the crew commander. The suspension loop should be worn on the pylon 10 with the middle of the rope 7 at the front edge of the pylon, and the rod 4 behind the pylon. Taking off, the helicopter holds the rope 3 behind the pylon 10, which ensures the sliding of the rope 7 along the front edge of the pylon and its entry into the groove of the hook 11, after which the loop extends in one line. This engagement moment is viewed by ground personnel and the operator, who give a signal to continue the helicopter to reach the calculated height, but with an airplane hanging on hook 11. This climb occurs with an increase in the horizontal speed of the helicopter to the takeoff speed of the aircraft. In the same period, when the aircraft began to navigate through the air flow, the operator gives the command of the self-propelled guns of the unmanned aircraft to start the engines and switch to take-off flight mode. At take-off speed, the aircraft increases the flight altitude, which reduces the pressure of hook 11 on the rope 7, and under the action of the spring 9, the rods 6 move apart, the rope 7 straightens and leaves the groove of the hook 11. This position is determined by the operator when the image of the body 5 and rod 4 appears on the monitor , which is a signal for the command of the aircraft self-propelled guns to turn left flat until it is completely removed from the clutch assembly and proceed to flight along the route. The landing of the aircraft begins with the commands of the aircraft’s self-propelled guns to descend to the height of the helicopter’s barrage and perform a mooring maneuver, ensuring that the middle (or close to it) of the rope 7 of the front edge of the pylon 10 is below the hook 11, which is controlled by the operator according to the image on the monitor of the body 5 and rod 4. B In this position, the aircraft sharply decreases, and the rope 7, sliding along the edge of the pylon, enters the groove of the hook 11, the levers 6 move closer, and the images of the body 5 and rod 4 disappear on the monitor, which is a signal to turn off the aircraft engines. After braking, the helicopter gently lowers the plane hanging on the loop of the external suspension to the ground, and, if necessary, it sits nearby, placing the aircraft and cable 3 in front on the port side.

The claimed helicopter external suspension device as a part of a helicopter and unmanned cargo aircraft can be used in the construction of various pipelines (pipes can be delivered directly to the installation site), when delivering goods to offshore oil and gas platforms, in remote places, as well as when monitoring in such regions. At the same time, the same helicopter with the declared external suspension device can be used with different unmanned aircraft, being for them a unified means of launch and landing. When using external suspensions of helicopters such as Mi-10k, Mi-26, the take-off weight of unmanned aircraft can reach 10-20 tons, and the payload is about 5-10 tons, which significantly increases the efficiency of the device.
