DE102015013100B4 - Tying and control system to fly several tethered aircraft simultaneously in the same airspace independently - Google Patents

Abstract

The novelty refers to a tethering and control system for tethered aircraft, which eliminates the pilot's turn in circles.
In addition, the number of aircraft in a circle can be increased.
The elevator, previously mechanically moved by the pilot over the fetters, is controlled by radio.
The lines are attached to a Hohltsylindesaeule so that they can move around them and on the column can ascend or descend arbitrarily.
This is done in each case by a bondage element, consisting of two components, each with a rare earth magnet installed.
One component is located on the inner wall of the hollow cylinder, the other on the outer wall. Both components magnetically attract each other through the cylinder wall.
Mounted on ball rollers, the pair of components, which are magnetically connected to one another by the high force of the magnets, can glide over the clamped lateral surfaces of the tube and withstand the tensile force of the circulating aircraft.
The motor-powered aircraft connects only a single fetlock line with the bondage element. The hovering helicopter can change the flying height over the elevator, thereby pulling the binding element on the pillar with it.
Independently of each other, several tying elements can slide on the column. Depending on the height of the column, the airspace height changes as desired.
By winding and unwinding the fetlock line via a winch in the aircraft, the radius of the flight circle can also be changed in flight and thus brings new maneuvers.
A video eye from the bondage element on the plane allows the usual view of the circle center.
Motor throttling and retractable landing gear are now also possible via radio.
In the interior, this system would be an addition to aircraft for the room operation.

Description

The innovation relates to tethered aircraft which are controlled by radio with a restraint system, which replaces the control with fettered pilots in the circle center.

Not only previously known but also novel flight maneuvers can be executed, which are made possible by the new system.

This restraint and control system is not only suitable for outdoor flying but also for the closed space.

The innovation concerns a bondage system, which adopts the tactics of pilots in the simultaneous, gemeisame flying in a circle, including the arm and Leinenfuehrung during a so-called fox hunting when overtaking or reversing the direction of rotation is necessary to avoid each other.

Due to the new restraint system, the number of aircraft is no longer limited to the same number of pilots, which have maximum space in the middle of the circle.

The innovation is illustrated by an exemplary embodiment of the closed space.

From the DE 000006812883 U generic binding systems are already known. However, there is a captive fastened to a column fastener element used. Thus, there the executable maneuvers are possible only to a limited extent.

Furthermore, the shows US 000008931144 B2 a controlled via a cable connection aircraft. Finally, the US 000004037358 A a held by magnetic means on the ceiling and controllable model airplane are removed.

The new bondage system 1 consists of a thin-walled hollow cylinder center column 1 that stands securely on the ground or is firmly anchored and the restraining elements 2 , which at the Oberflaechenjder Mittelaeule 1 be able to slide over them and slide freely over them, both from bottom to top and back down, as well as around the middle column 1 around. In this case, no mechanical connection can be seen, because push two bondage elements 2 when overtaking 2 or accommodating with their bumpers 5 Together, they must be able to pass each other, either left or right around, or above 5a or below 5b.

The bondage element 2 consists of the component part 2a , which is located on the outer surface of the hollow cylinder Mittelaeule 1 located and in 3 the component part 2 B , which is located on the inner surface of the hollow cylinder Mittelaeule 1 located. The component parts 2a and 2 B in 2 . 3 and 4 are each on four ball roller bearings 2c stored, which allow sliding in each direction.

In order to obtain a liability to the inner and outer surfaces of the hollow cylinder Mittelaeule, are in the component parts 2a and 2 B each rare earth magnets 3 and 4 built in, pictured in 4 ,

The extremely strong attraction of these magnets causes the two opposite component parts 2a and 2 B through the cylinder wall of the middle column 1 strong, but still easy to roll off.

To the two component parts 2a and 2 B Depending on the size of the magnet, a certain tensile force is required, which can even go as far as the kilonewton range for relatively small rare earth magnets, if this is necessary. In order to ensure a safe grip, this traction must always be much greater than the centrifugal force that can generate a pennet at maximum speed.

The two component parts 2a and 2 B be in 1b at the foot of the middle column 1 Installed. The component part 2 B passes through the mouth opening 11 into the interior of the middle column 1 ,

The middle column 1 owns at the top in 1a an inward supernatant 12 which prevents an airplane from being captive 2 can pull out of the Zylinderoeffnung when flying up. A ball bearing 13 in 4 and 1a presses from below against the ring-shaped supernatant 12 and roll along it. The middle column 1 is similarly trained at the foot. The ring-shaped supernatant is located there just above the Saeulenoeffnung 11 , The ball bearing 14 in 4 rolls off when a captive element 2 at the start of an aircraft at the very bottom of the center pillar 1 located.

Due to the strong magnetic force of the rare earth magnets 3 and 4 , remains the weight of the bondage element 2 relatively low, so that the aircraft engine the captive element 2 lift easily and this can rise easily on the column. Depending on the height of the Mittelaeule 1 The airspace is increased in comparison to the conventional tether flight upwards and creates additional space for several aircraft.

The steering takes place via radio and in contrast to the conventional, mechanical line control, the pilot is outside the flight circle.

Via a screen or a video eyeglass, the aircraft can also be viewed from the center of the circle and controlled by a video eye at the end of the line (not shown) in the tethering element 2 attached and focused on the circling aircraft.

Through the over a servo, integrated in the receiver 7 , radio-controlled elevator 8th in 5 and 5b is enough for a single, thin leash 6 to the bondage.

This leash 6 can over another radio channel of a conventional receiver 7 from a bindlass winch 9 be unwound and unwound in the aircraft, shown in 5 and 5a , This will make the circle radii 10 in 1 controllably changed.

The possibility of changing the flight radius through the single-line system results in new flight maneuvers for the tether flight, especially in the so-called fox hunt.

A traditional receiver 7 usually has more channels suitable for engine throttling and retractable landing gear. In the known bondage, these functions are only limited possible.

For the closed space only an electric propeller drive comes into question for this new type of binding flies, consisting of the aircraft engine 16 and a lithium polymer battery 15 represented in 5 and 5a ,

Outdoors, this system provides a new incentive for quiescent engine tethering to break speed records, as the air resistance caused by a single line is less than that of a mechanical twin line steering system.

This new type of restraint system and a change in the control system, from mechanical to electronic control, not only modernizes the once-popular and now rather suppressed tethering flight, but also expands the possibilities for new maneuvers simultaneously with multiple aircraft in the common airspace can be performed.

This is also the, especially in fast aircraft, dizzying co-rotation of the pilots during the control of the circle center, disappeared. Depending on the height and diameter of the Mittelaeule, the number and size of the joint aerial models in the air can occupy a fairly wide range. This results in interesting perspectives for competitions with new disciplines.

At the same time, this restraint and control system opens the captive flight for the closed space, which was previously reserved for simple flying toys. The latter, however, can no longer withstand today's requirements with regard to aerodynamics and control technology of flying objects in a closed space.

In the miniaturized area, one could imagine for trade Fesselflugsysteme with 1 to 3 airplanes, which operate like small helicopters in a closed space and therefore can be operated even in the room size of a normal room.
