DE3207594A1 - Aerodynamically supported aircraft, driven by a pushrod, as a toy and sporting appliance - Google Patents

Abstract

A person who is moving or being moved pushes the aircraft in front of him by means of a rod or merely holds it in the wind. The draught formed or existing relative to the aircraft supports the latter. The stabilization of the flying height desired in each case is achieved by means of this rod and longitudinal force transmitters located on or in the latter (Figures 2 and 3). The stabilization of the turning bank recommended in each case is likewise achieved by means of longitudinal force-transmitting auxiliary means along the rod. The invention is principally for use as a toy and sporting appliance. <IMAGE>

Description

Aerodynamically supported, propelled by means of a push rod

Airplane as a toy and sports equipment description The invention relates to an airplane model as a toy and sports device, which is driven and controlled with the help of a push rod, Fig.1.

With the invention, a toy is realized, which the natural Way of movement and the need for movement, especially of children with play that all remote-controlled airplanes offer. In doing so, the plane will go through constantly accompanies your own running movement, it is controlled manually from close by, and it always remains cheap in the field of vision, which is a special, additional stimulus to play supplies. Such an aircraft model can also be made from land and water vehicles as well as being operated on roller skates and other means of transport.

Toys + aircraft that are in constant contact with, for example by means of strings of the person playing are known as tether planes, tugs, Tow helicopters, kites. An airplane model pushed by means of a push rod is unknown in the toy market.

There are only limited possibilities for the toys listed above the influence on the course of the flight. The invention was based on the running task placed, such wishes of influencing the course of the flight, that is, according to to meet a flight behavior that is controllable in height and direction. In addition The aim was to create a toy that was as simple as possible, purely mechanical and inexpensive.

In all of the embodiments of the invention, the aircraft model is included pushed by a push rod. A favorable length of this push rod is 2 to 3 m, the airplane model has a typical wingspan of 50 to 60 cm. The push rod Depending on the design, it can be moved in one or more degrees of freedom on the aircraft appropriate. In most designs, it will also have one on the other end movably mounted control handle or control stick, which when operating the Aircraft is held in one hand in a normally vertical position. He serves at the same time to push the aircraft and to transmit the control commands, what by means of further push-pull rods or cables. as well as by twisting the push rod takes place around its longitudinal axis.

The following control functions can be exercised: backwards or press forward <tilt) the joystick to adjust the angle and thus the Control a climb or descent; tilt the joystick to the right or left to control the lateral inclination of the aircraft or the turn; Turn the handle on the control stick, also about the lateral inclination or the turn to control. Not all of the embodiments of the invention are cited Functions used.

The altitude is controlled by changing the angle of attack of the aircraft, see Fig. 1 and 2. This is possible by extending the flaps on the Tail unit or on the wings if the aircraft with adequate freedom of movement is adapted in this direction of rotation.

In some embodiments of the invention, height control is used @@@ @@@@@@ between the rear axle and the push rod depending on the Angle between the joystick and the lift rod by a mechanical angle transmission forcibly carried along. This can be done first for easier understanding it is assumed that the airplane, the push rod and the control stick are so interrelated are connected that they always move in the plane of symmetry of the aircraft.

This principle of height control is illustrated in an example realized in that the push rod consists of two rods from the upper or lower end of the control stick, starting parallel to the vertical tail unit (to Vertical stabilizer dummy) run and there on one of its length the control stick corresponding route are adapted. This can be done in the form of a parallelogram carry out. Instead of the parallelogram principle, the angle transmission can also by other square + shapes, as well as by other mechanical arrangements, e.g. via a directly adjacent or concentrically attached to the push rod Pull-push rod take place, with the movement and at the ends of the push rod Force branches go over two more short push-pull rods. Likewise is the Realization of the angle transmission with pull cables or using a rack realizable. From a complete listing of the possibilities according to the state technology is disregarded here, without affecting its inclusion in the Property right should be waived.

In another embodiment of the invention, instead of the im Angle transmission described in the previous section an angle transmission applied, see e.g. Fig. 2 and 3. This means that a change in the angle "control handle-push rod" a larger change in the same direction of rotation of the "fuselage longitudinal axis-push rod" angle causes. This achieves two goals: First, the aircraft is more sensitive on the joystick. Second, this has the effect of aerodynamic flight altitude stabilization. Depending on the position of the control stick, the aircraft will oscillate at the same speed, always at a constant flight altitude (Fig. 2 and 3). the Angular transmission in the example of the parallogram arrangement becomes a Angle translation that on the side of the aircraft the two rods in shorter Distance are attached than on the joystick.

The same applies to the other principles of angle transmission.

The change of the flight direction is possible through an "angle transfer" (-setting) "similar to that used for altitude control.

As a control function, e.g. a turn of the handle is to be carried out, which causes the aircraft to bend sideways from the alignment of the push rod. This technique assumes that the aircraft is standing vertically with a sufficiently large Surface (vertical tail dummy> is provided, or that the wings are arranged in a V-shape are.

Turning is more economical if the aircraft as is common in aviation technology, brought into a lateral incline (Fig. 4 and 5). Then the curve radius can also be influenced by means of the height control will.

In one embodiment of the invention, the aircraft is shown in FIG brought the desired incline that the joystick to the desired Side is tilted, whereby the push rod is rotated and over this the aircraft inevitably tips over.

The aircraft and the push rod are torsion-resistant with one another connected (Fig. 1,2,3,5).

In another embodiment of the invention (Figure 5), the aircraft wired in an inclined position by turning the handle on the joystick into the desired position The direction of the curve is rotated and thus the wings are twisted via four control threads be that the aircraft with a screwing movement to the required incline inclines and maintains it stable. The aircraft essentially only exists from the two wings, which are mounted on a transverse axis. She educates the front end of the push rod. There are two levers on each wing. Appropriate Outriggers are also attached to the rotating control handle, two to the right at the top and left, also below The control threads are attached as follows: Below right from the handle to the bottom right of the aircraft. Ditto at the bottom left. Top right of the handle to the top left of the aircraft and to the top left of the handle to the top right of the aircraft. With this arrangement, the functions of the altitude control are at the same time Stabilization, the curve position with stabilization and the curve radius determination given.

In another embodiment of the invention (FIG. 4), the incline of the curve is also achieved by twisting the wings.

Here the push rod is rotatably attached to the aircraft. By Tilting the joystick in the desired direction of the curve becomes a part of the fuselage Rod with a two-sided, T-shaped arm rotated to the yorderen wing tips, while the aircraft initially remains in its old position. The booms twist the wings, which are also mounted here on a transverse axis, so that adjusts the curve position as with the previously described Sus guide.

With such a thruster the risk is to be met that it erupts unstably from the direction of flight. Therefore, in one design, the shape. of a delta aircraft (Fig.7) chosen, which is on the rear side of the wing has an incision close to or in front of the center of gravity through this Nick engages the push rod on the plane and has the necessary one here too Space to swing up and down.

1 shows the basic principle of the invention: The running person 1 pushes over the push and control handle 11 and over the push and control rod 12 the airplane 40 in front of him. It floats carried by the draft.

Figure 2 shows the push and control handle 21 held in an angular position alpha H. This is the command angle for high flight. The plane hovers in the intended High flight position 50H and is kept stable there via the height control rope 22 and Bar 23.

If the target position is too low (at 52), the aircraft forcibly takes off a steeper angle of attack, if too high (at 51) the aircraft will take one lowered angle of attack, in both cases it is in the sense of an automatic Altitude stabilization level back to the target altitude 50H.

4 shows the missile without the sketched right wing.

The thrust and control shaft 61 transmits the one imposed on it by the handle Rotational position via the universal joint 62 and the shaft 64 mounted in the fuselage on the double twisting lever 65. This makes "up and down" at its ends, depending on the twisting of 61 Movements and transmits them. via the transmission eyelet 67 on the wing noses. The wings are rotatably mounted on the nose fixed to the fuselage, for example by means of 66. In this case, a rotation of 61, e.g. to the right, will turn the left wing in front raise and lower the right wing at the front, thus creating a wing twist, which turns the aircraft clockwise as seen from behind. This is in addition to that of the right - @@@@@ - twisting @ of 61 directly to the @@@@@@@@ @@@@@@@@@@ @@@@ moment So the aircraft is banked for two reasons. A right turn is initiated.

Flg.5 shows a torsionally rigid connection between 70 and the missile About the push rod axis 73. Ends 4 rope hooks 74 is the crossed pull rope pair at the top 71 and below the parallel pair of pulling cables 72 hooked, the pulling cable pairs are hooked onto the steering handle (not shown).

In FIG. 4, the steering handle is around the longitudinal axis for the purpose of generating torsion to twist the push rod and control rod. In Figure 5 he is on his own (handle) axis to twist. In Fig. 4 and 5, the steering handle is around a transverse axis for flight altitude selection (as with a real control stick), see angle alpha in Fig. 2 and 3.

In Figures 4 and 5, the respective incline of the curve commutes itself a.

The torsional rotations of the wings (FIGS. 4 and 5) can according to the invention limited only to the wing that occupies the steeper pitch angle, by the otherwise flatter or even negative angle of attack of the other Wing's resulting loss of lift during entry and exit into and out of a curve to compensate.

Fig. 6 shows a handle 80, the rod 82 and the missile 83 and the course of traction cables 81. These are above a central region of the rod 82 to prevent it from fluttering and the risk of the rod buckling to reduce.

7 shows that the point of action of the rod 82 on the missile 83 is positioned in the approximate center of mass and buoyancy of the same, allows by creating space 84 for the space required by the pivoting rod 82.
