Description

SIMULATOR FOR GETTING RID OF ENTANGLED PARACHUTE ROPES

Field of Invention

This application is related to the simulator where the parachute ropes can be tangled after jumping with a parachute in the Parachute Jumping Training Simulators and the scenario of recovery is taught.

The simulator prepared is used in airline companies, universities, or private companies for training purposes.

Background of the Art

Parachute jumping training simulators are ground-mounted training systems that simulate environmental conditions for the training of people who will jump. The American patent application US2003113695 generally describes a parachute jumping simulator and training process. In this simulator, the environmental conditions are simulated and the training of the process until the person who will jump lands from the aircraft is explained.

The American patent application US2020398991 also describes a simulation system in which pilots are trained for a safe jump. In this system, how to eliminate vertigo and G-LOC hazards that pilots may encounter is emphasized.

Other examples of parachute jumping training simulators are described in the Japanese Patent applications JPH031 6476, JPH08182787, and JPH08173583 and the Korean patent application KR20150096581.

However, none of these inventions provides information on how to get rid of an entangled rope during jumping.

In the state of the art, the Inverted Scissor Lift System is used to get rid of the entangled rope during parachute jumping training. In order to better understand this art applied before the present invention, first of all, the training on parachute jumping rope elimination is explained in the following paragraphs and with the help of Figure-1 and Figure-2. At the beginning of the training, the personnel connects themselves to the system by wearing their parachute hanging down from the system hanging above. The total height of the system is approximately 10 meters. When the training starts, the feet of the personnel are on the ground and the ropes (5) of the parachute to which the personnel is attached provide the ideal conditions and each of them hangs flat from the mechanism to the parachute. With the training start command, the canopy part (4) to which the parachute ropes are connected above allows the ropes to be entangled by 8-10 turns thanks to the rotation motor (6). After these entangled ropes (5), the system moves up 50-100 cm and lifts the personnel into the air. And in the end, the staff finds themselves in the air with the parachute ropes entangled. The main training will then be for the personnel to try to untie the entangled ropes while they are in the air by performing correct hand and foot swing movements.

In this training simulator system, the mechanism used to lift the personnel in the previous art is the scissors lift system (1 ), which is designed inverted and connected to a rigid structure above, and the electric motor and steel rope winding mechanism (3), that is, the crane system. In this previously applied structure, the task of lifting and downing the system is completely the motor and the steel rope winding mechanism (3) to which it is attached. In other words, steel ropes (2) carry all the load. The task of the inverted scissor lift system (1 ) used is to ensure that the up-down movement is performed linearly.

The Inverted Scissors Lift System has many drawbacks and is listed below:

• The scissor lift lifts steel ropes. If these steel ropes miss or break from the connection points, the scissor lift will release itself freely downwards. In addition to the personnel falling hard to the ground, there is a risk that the approximately 400 kg scissor lift system will fall on the personnel from approximately 10 meters.

• The inverted scissor lift system stretches too much in the oscillating movements to be applied by the trainee and the system itself makes oscillating movements. First of all, education cannot be simulated correctly. In addition, as a result of these oscillation movements, all switch lift connections are constantly subjected to dynamic loads. While these dynamic loads cause material fatigue in the long run, fractures and cracks may occur.

• In the long term, there is a risk of stretching the ropes and the lifting height is not sensitive. • It has a complex structure, as it consists of many parts. This increases the risk of error in the system and increases the maintenance time and costs.

The object of the Invention

The object of the invention is to develop a mechanism in parachute jump training simulators, in which the height value in the entangled rope release simulator is sensitive, unaffected by oscillating movements, and ensures that the personnel is lifted steadily.

Another object of the invention is to develop a safe, sensitive, simple, and cost-effective lifting mechanism that works healthily in the long term.

Description of the Invention

The scissor lift system (1 ) in the prior art was explained with the help of Figure-1 and Figure-2 in the case of the above known art.

In the parachute jump training simulators according to the invention, the lifting mechanism system in the entangled rope release simulator is much safer.

Height values are sensitive because they provide more precise movements.

It ensures that the personnel is lifted stably without being affected by oscillation movements.

When the personnel is above, they are not affected by the oscillation movements of the personnel and it is ensured that the system operates healthily in the long term.

In parachute jump training simulators, the lifting mechanism in the entangled rope release simulator consists of the electric motor (7), the screw shaft (9) connected to this motor, and four linear bedding systems (8). The motor shaft will start rotating after the rotate command is given to the electric motor (7) for lifting operation. The screw shaft (9) connected to the motor shaft starts to rotate with the motor shaft. As the screw shaft (9) starts to rotate in the special nut (10) located at the top of the canopy, the canopy part moves upwards. With this movement, the personnel also start to be pulled upwards by means of ropes. The four linear bedding systems (8) in the system during the movement ensure that the movement takes place linearly and stably. When the desired height is achieved, the electric motor (7) is stopped and the training to get rid of the entangled rope starts.

In the present invention, the screw shaft (9) system does the lifting work instead of steel ropes. There is no risk of slipping down when lifting the screw shaft (9) system. The material strengths used in screw shafts are fairly high due to the work they do.

In the invention, linear bedding is made from four sides to reset the effect of the oscillating movements made during the training on the mechanism. Linear bedding systems ensure stable movements even on sensitive machines such as three-dimensional printers. In addition, since the screw shaft (9) is used in this invention, the height lifted is sensitive and will maintain this sensitivity in the long term. Finally, in the present invention, the system is simplified by using the screw shaft (9) system with the bedding system (8) that maintains the stability of the lifting system. There are many connections in the scissors lift system (1 ) used in previous applications together with the multiarticulated structure, many reel systems, and fittings for steel ropes.
