DE2852322C2 - Device for controlling the motion sequences of a flight model - Google Patents

Description

The invention is based on a device for controlling the movement sequences of a flight model which is driven by a drive motor, A screw spindle arranged axially parallel to the motor shaft is provided with an internal thread and in the longitudinal direction the screw spindle for the trim component is mounted.

In the magazine "Flug + modell-technik", 1968. Booklet 2, ropes 60, describes a trim rowing machine, which consists of a drive motor with gearbox, on which a screw spindle is attached, which a pipe with thread is guided, this pipe is connected to a flat brass part which runs on a steel wire at one end. The front one The end of the flat brass part is connected to a push rod that is inserted into a brass part of the Elevator machine intervenes, according to the position of the pipe more or less to the right or move left.

In DE-OS 19 63 530 is a hovercraft described, in which a weight is used to stabilize the vehicle, which is on a Axis can be moved lengthways and can be locked with a screw. An electric motor is used over a handlebar angular movement of the toggle rod generated, which is limited by stops. The constant back-and-forth movement of the weight becomes a kind of "swaying movement" is generated.

In the magazine "Mechanikus". 1956, issue 2, pages • 2 and 83, a spindle control is described in which a nut is coaxial with the motor shaft arranged screw spindle runs and actuates the steering lever of the front axle of a car model.

The invention described in claim I is based on the in the magazine »Flug + Modell-Technik «described device, the task underlying to design such a device so, that they can control the flight attitudes of simple smart models with little structural effort. Kite and hang gliding can be used.

With the device according to the invention, the essential advantage is achieved that due to their low Installation in the named model aircraft and kites can be carried out if required. Furthermore can with the device according to the invention in the weight connected to the trim components, the electronics be accommodated, whereby a counterweight to the respective in certain embodiments Drive motor can be created.

With the embodiment of the device according to claim 2 it is achieved that by using both The motor shafts of the motors end at right angles to each other in the center of gravity of the flight model or kite can be arranged.

With the configuration of the device according to claim 3, the screw spindle is known per se Way arranged coaxially to the motor shaft, resulting in a simple symmetrical structure of the device results.

With the aid of the drawing, the device is intended to be wet using the example of a preferred embodiment the invention will be explained in more detail.

The drawing shows a basic arrangement of the device according to the invention for controlling a Kite.

As can be seen from the drawing, two electric motors are below the kite 1 shown in dashed lines 2 and 2 'arranged at right angles to one another. These drive motors can by not shown, known control means are displaced from a standstill in two directions of rotation.

The two drive motors 2, 2 'each have two motor shafts 3 and 3', protruding on both sides. which are either coupled or simply represent extensions of the motor shafts. On the motor shaft 3 of the first drive motor 2 is fixedly arranged on each side a screw spindle 4 on which the Trim components 5. In the present case, bodies provided with internal threads are screwed on. These Trim components run smoothly on the screw spindle and each have a guide rod 6. the on Slide guides 7 run. By rotating the motor shaft 3, the trim components are 5. depending on Direction of rotation, moved up or down. On the guide rods 6 are on both sides Weights 16 attached, which depending on the control of the drive motor 2 moves up or down can be.

The same arrangement is analogously on the second drive motor 2 ' , which is arranged perpendicular to the drive motor 2, with the two motor shafts 3'. the trim components 5 ', the guide rods 6' and the sliding guides T are provided, with the only difference that depending on the direction of rotation of the second drive motor 2 ', the trim weights 16' move to the right or to the left.

On the two trim systems are also on the respective outer protruding ends of the motor shafts 3 or 3 'coil springs 8,8' and 9,9 'arranged, the against washers 10, 10 'and 11, 11' firmly connected to the motor shafts 3, 3 ', and the loose, on the motor shafts 3, 3 'seated washers 12, 12' or 13, 13 'from both sides against the Press screw spindles 4,4 '.

If now the trim components 5, 5 'provided with internal threads, depending on the direction of rotation individual motor shafts have reached one or the other end of the screw spindle 4, 4 ', the

Trim components 5.5 'completely detached from the screw spindles 4.4' and! zr, for a further ·· turn of the

corresponding coil springs 8,8 'or 9,9' however, they are constantly pressed against the screw spindles 4, 4 '.

Now the direction of rotation of the Anirbsmotore 2, 2 'vice versa, then the corresponding coil springs 8, 8' or 9, 9 'press the eiuspreeheedt .s Trim components 5, 5 'so long on the now penetrating into the bores of the trim components 5, 5' Screw spindles 4, 4 'until the trim components are screwed on and now in the one or anccii .-- '! HiWit'iiig be moved. This will make the Guide rods 6 up or down and the guide rods 6 'moved to the right or left. The associated shifting of the weights 16 and 16 'makes it possible to use the flight model, the kite or to provide the hang glider with an altitude and a rudder control, for example from the Floor made by means of a corresponding pipe guide, but can also be triggered wirelessly via radio. It is of particular advantage that at each Set a switch of the drive motor 2 or 2 'possible hi, so that a different Steuerbewegimg can be initiated independently of the first tax movement.

It is easily possible, within the scope of the device shown, to counteract the drive motors to relocate, with only the motor part 3 'of the second drive motor 2 'run at right angles to the motor shaft 3 of the first drive motor 2 got to.
