Description

The invention relates to two areas - to amusement rides and to professional sports simulators and can be used for entertainment purposes or for training athletes-paratroopers or paratroopers.

There are well-known parachute towers that used to be used for training DOSAAF athletes, see the Great Soviet Encyclopedia, Volume 11, p. 319. However, they only allowed simulating a parachute jump, not allowing to train all phases of a parachute jump: free flight, opening the canopy, descent, including - managed.

Currently, for recreational or training purposes, parachute jumps are carried out using airplanes or helicopters, which is relatively expensive and dangerous - if an accident or failure of aircraft occurs at altitudes up to 100 meters, then a group of parachutists can crash together with an airplane or a helicopter, since such a small height, the parachute may not have time to open, especially - given the stress factor.

The objective and technical result of the invention is the implementation for entertainment or training purposes of real parachute jumps.

OPTION 1. For this, the attraction simulator contains a parachute, a balloon connected by a cable to a heavy winch on the ground and having a controllable mount for the parachutist.

In FIG. 1 shows option 1, where: 1 - an aerostat connected by a cable 2 to a winch 3 on the ground. A parachutist is temporarily attached to the balloon in any way (for example, controlled by a castle or a special marine unit).

The attraction simulator works as follows: a balloon 1 descends to the ground, a parachutist 4 with a parachute (the last one is not shown) is attached to it, and the balloon rises to a predetermined height (300 m and above). After this, the paratrooper is separated from the balloon and carries out a parachute jump.

For reliable opening of the canopy of the parachute can be applied forcible opening.

To increase the capacity for the balloon, several parachutists can be suspended simultaneously. And in this case, a lightweight duralumin or composite basket for several people may be appropriate.

This option is simple structurally, however, it has a significant drawback - the low speed of descent and especially the rise of the balloon, that is, too long a cycle of one jump. Option 2 is free from this drawback.

OPTION 2. This version of the attraction simulator contains a parachute, an aerostat connected by a cable to a heavy winch on the ground, and an additional winch and an additional cable attached to the aerostat using a block and having a controlled mount for the parachutist.

In this embodiment, the speed of raising and lowering the additional cable is limited only by the drive power of the additional winch and can reach significant values - 20-30 m / s.

However, this option also has one drawback - in order for the additional cable to fall from the upper position, it must have a load at the end that weighs more than half the weight of the additional cable. The energy of the winch drive will be spent on lifting this parasitic mass. Of course, in this case (as in all other versions), a cable made of modern light and durable materials should be used: zylon, daima, spectrum, vectran, modified polyethylene, etc.

But this option has a significant advantage - the parachute can be fixed to the additional cable, and the reliability of the jump will increase dramatically - if the dome is not opened, the paratrooper can be lowered to the ground by lowering the additional cable. However, a special “inertia-free” design of an additional winch (similar to a non-inertia spinning fishing reel) with a safety friction clutch is desirable.

In FIG. 2 shows the second option, where: 1 - a balloon connected by a cable 2 to a winch 3 on the ground. On the additional winch 5 there is an additional cable 6 thrown over the pulley 7 on the balloon. The additional cable has a load 8 at its free end.

The second option works like this: with an additional winch 5 with the help of an additional cable 6, the paratrooper 4 rises to a predetermined height, after which the paratrooper disconnects the temporary mount and makes a parachute jump. Then the additional winch 5 is included in the descent, and due to the load 8, the free end of the additional cable quickly drops behind the next paratrooper. After a series of jumps with the main winch 3, the balloon 1 descends to the ground and fastens in a storm.

This option has two small drawbacks - the presence of two cables, the total mass of which is greater than the mass of the cable in option 1, and the presence of spurious cargo. Option 3 is free from these shortcomings.

OPTION 3. This version of the attraction simulator contains a parachute, a balloon connected by a block and an endless (that is, looped) cable with a series of pulleys located in the hollow drum of the winch, and the pulleys have a motor (s) also located in the drum.

The paratrooper in this version rises by rewinding the looped cable through the pulleys. It is clear that the pulleys must be made of friction material (for example, rubberized) and are located in one or several planes so that the cable bends around them as tightly as possible.

In FIG. 3 shows the third option, where: 1 - an aerostat connected by a looped cable 9 with a hollow drum of winch 3 on the ground. A series of pulleys 10 are located in the hollow drum (located one after the other in the same plane on the sketch), driven by one or more motors 11. There is a temporary mount for the parachutist 4 on the looped cable.

The third option works like this: motor 11, rotating a series of pulleys 10, rewinds the looped cable 9 passing through the pulleys, raising the paratrooper to a predetermined height and lowering to the next one. After the series of jumps, drum 3 is turned on, and it simultaneously wraps two branches of a looped cable, while lowering the balloon 1. The winding can be driven in bulk or with the help of a stacker.

This option is free from all previous drawbacks, but has its drawback - the complexity of the design. And also there is a danger of twisting two closely spaced branches of the looped cable, which will lead to increased friction and wear between them.

OPTION 4. This version of the attraction simulator contains a parachute, an aerostat connected by a block and a cable passing through it with two winches on the ground, with a controllable temporary mount for the paratrooper fixed to about 1/3 of the cable. This option is free from all previous drawbacks, but it has its own - the mass of the cable in this case will be one and a half times more than in option 1 or 3, and approximately equal to the mass of the cable in option 2. That is, if you need to raise the paratrooper to a height of 300 meters , then taking into account the wind slope, approximately 1050 meters of cable will be required, of which 700 meters on the left winch in the sketch and 350 meters on the right. This option also has one feature - it is desirable to place two winches at a certain distance from each other (from 3 to 300 meters).

In FIG. 4 shows the fourth option, where: 1 - an aerostat connected by a cable 2 with two winches 3 on the ground. A parachutist is temporarily attached to the cable in any way (for example, controlled by a lock or a special marine knot).

The fourth option works as follows: including one of the winch 3 on the descent, and the other on the rise (shown by arrows), lift the parachutist 4 to a given height. After which it detaches the cable 2 and carries out a parachute jump.

When using any of the device’s options as an attraction, there may be a case when a person, having panicked from an increasing height, can, in stress, open a controlled attachment of a paratrooper to a cable or to a balloon ahead of time - at a height insufficient to open the parachute. This can lead to personal injury and even death. To avoid this, a radio-controlled locking of the handle of the opening of the controlled mount is possible - when the specified height is reached, a radio signal is emitted, a sound signal sounds, after which the controlled mount can be opened.

Or a variant is possible when the mount opens by radio signal. But it requires more electrical power for the drive mechanism.
