Abstract

PURPOSE: To conduct multiple types of parachuting training by providing a sensor detecting the operation quantity of a riser, a sensor detecting the operation quantity of a control line, and a control means receiving the parachute type and operating either sensor. CONSTITUTION: When a parachute operating the advance direction with a riser 24 is used, the type A is set. When a control line 26 is wound up and a trainee 23 operates the riser 24, the momentum of the parachute is calculated in response to the operation quantity detected by a strain gauge SR, and the descent image and descent sound are changed. When the advance direction is operated by the control line 26, the type B is set. The control line 26 is lowered, and a toggle TG is located at the trainee 23. When the trainee 23 operates the control line 26, the momentum of the parachute is calculated in response to the operation quantity from an encoder SC, and the descent image and descent sound are changed. Multiple types of parachuting training can be conducted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parachute maneuvering training simulator.

[0002]

2. Description of the Related Art FIG. 4 is a diagram showing a conventional example of a parachute driving training simulator (Japanese Patent Laid-Open No. 3-126476).
Issue).

In the simulator shown in FIG. 1, a descending port 2 is provided in the vertical wind tunnel 1A of the wind tunnel device 1.
The trained personnel 3 consist of a suspension device 4 provided on the top of the vertical wind tunnel 1A, a safety rope 5 and a parachute 6 for simulation.
After being equipped with the above-mentioned guide cable, it is adapted to descend from above the descending table 7 into the vertical wind tunnel section 1A via the descending port 2. A flat screen 8 is provided on the lower surface of the vertical wind tunnel 1A, that is, under the eyes of the lowered personnel 3.

In such a simulator, when the parachute is opened, the personnel 3 suspended by the suspension device 4 via the parachute 6 and the guide rope 10 detects a deviation from the target position when the guide rope 10 is actually descended. Do the same. Then, the direction of descent according to the operation amount is simulated by moving the scenery on the screen 8 under the eye so that the user finally descends to the target location. Incidentally, 9 is a landscape device, and 11 is a simulator device.

[0005]

FIG. 5 is an external view of a typical parachute.

The parachute shown in the same figure has a main umbrella P1 which is mainly in the shape of a crown, a plurality of lines L1 whose upper ends are connected to the outer periphery of the main umbrella P1, and four lines L1 which are divided into four bundles. And a riser R1 (hereinafter referred to as “A type”).

The number of personnel M1 suspended from the riser R1 is 4
When one of the book risers R1 is pulled, the riser side portion of the main umbrella P1 is deformed and the drag force changes, so that the parachute turns in the direction in which the riser R1 is pulled.

That is, this parachute is a riser R1.
It is designed to be operated by.

On the other hand, a control line has been developed separately from the riser, and the control line is used for steering (for example, a paraglider, hereinafter referred to as "B type").

FIG. 6 is an external view of another type of parachute.

The parachute shown in the figure has a main umbrella P2 having a wing-shaped cross section and a quadrangle, a plurality of lines L2 having upper ends connected to the outer periphery of the main umbrella P2, and a plurality of lines L2 divided into four. It has four risers R2 that are bundled together and a control line CL that is connected to the end of the main umbrella P2 and extends to the hand of the personnel M2 and has a toggle T attached to the lower end.

When the personnel M2 suspended from the riser R2 pulls one of the control lines CL, the portion on the side to which the control line CL is connected (the right rear portion or the left rear portion of the main umbrella) is deformed and the drag changes. Therefore, the parachute turns in the direction of pulling the control line CL.

That is, this parachute is designed to operate in the traveling direction by the control line CL.

Further, since the cross section of the main umbrella P2 has a wing shape, buoyancy is obtained and gliding performance is very good. Therefore, it can fly like a glider.

However, only one type of parachute is used in the device described above.

Since the A type and the B type have different control methods and glide performance, parachuting descent training using the B type parachute was not possible with the above-mentioned conventional simulator.

Therefore, an object of the present invention is to solve the above problems and provide a simulator for parachute maneuvering training capable of performing a plurality of types of parachute descent training.

[0018]

In order to achieve the above object, the present invention provides a plurality of risers and a control line for suspending a descending trainee in a descending state on a cradle,

Control means for activating one of the sensors and lowering the control line when the control line sensor operates.

[0019]

According to the above construction, when performing descent training using a parachute (A type) whose traveling direction is controlled by the riser, when the type of the parachute is input to the control means, the control line rises. The descending image changes according to the operation amount from the riser sensor. Parachute (B type) that controls the direction of travel with the control line
When performing descent training using, when the type of the parachute is input to the control means, the control line descends and the descent image changes according to the operation amount from the control line sensor. That is, a plurality of types of parachute descent training can be handled by operating either the riser sensor or the control line sensor according to the type of parachute.

The tension drum TD operates to rewind the control line 26, the control line 26 descends, and the toggle TG is located near the trainee 23.

When the trainee 23 operates the control line 26, the encoder SC detects the operation amount and inputs it to the host computer 36 via the input / output control device 51 (in this case, the trainee 23 mistakenly raises the riser. Even if 24 is pulled, the host computer 36 does not receive the signal from the strain gauge SR.) The host computer 36 calculates the motion of the parachute in accordance with the operation amount from the encoder SC, drives the simulated image generator 38, and simulates the sound. Since the generator 37 is driven, the descending image and the descending sound change. The trainee 23 can receive parachute driving training by the control line 26.

As described above, according to this embodiment, four risers, a riser sensor for detecting the operation amount of the risers, a control line provided up and down from the gantry to the trainee's hand, and the control lines are provided. A control line sensor for detecting the operation amount and a control means for inputting the type of the trainee's parachute and activating any of the above sensors and lowering the control line sensor when the control line sensor operates Therefore, the descent training of the A type parachute and the descent training of the B type parachute can be freely switched by one simulator.
