However, the above-mentioned conventional simulator for parachute maneuvering training can perform descent training when the parachute is fully opened, but when the parachute fails (twist of the line, Training that assumes line breaks, incomplete opening, etc.) cannot be performed.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a parachute maneuvering training simulator that allows a descent trainer to experience a parachute failure when the parachute is opened.

[0007]

In order to achieve the above object, the present invention is a parachute maneuvering training simulator that allows a descent trainer to experience a parachute failure when the parachute is opened. A suspension means for suspending the suspension means, a failure generation means for swinging and suddenly descending the suspension means to generate a failure at the time of opening the parachute, and a display means provided in front of the descent trainee for displaying the content of the failure. A failure control means for setting a failure situation, activating the failure generation means in accordance with the setting, and displaying the situation on the display means is provided.

In addition to the above structure, the present invention is provided with a leg support means for holding the legs of a descent trainer on a gantry and suspending the descent trainer in a skydiving state by suspending means, which causes a failure. The control means, when the opening operation is performed,
The failure generation means may be operated in accordance with the failure condition set immediately after the leg support means is released.

In addition to the above structure, the present invention is provided with a slidable floor on which a descent training person stands by under the descent training person on the gantry, and the descent training person jumps down from the floor and is hung by the hanging means.

Here, the types of parachutes will be described.

FIG. 3 is an external view of a conventional parachute with a free-fall umbrella.

The parachute shown in the figure is mainly a crown-shaped (when the umbrella is open) main umbrella P1, a guide umbrella S1 connected to the upper part of the main umbrella P1, and an upper end connected to the outer peripheral portion of the main umbrella P1. A plurality of lines L1 and four risers R1 that divide the plurality of lines L1 into four and bundle them (hereinafter referred to as “A type”).
Say. ). These main umbrella P1, guide umbrella S1, line L
1 and riser R1 were folded before the descent and personnel M1
It is housed in a container (not visible in the figure) that the person carries on his back.

The parachute is opened by pulling the lip code RC when the personnel M1 descends from an aircraft or the like to enter a skydiving state. That is, when the personnel M1 pulls the lip code RC, the guiding umbrella S1 is first opened. The guide umbrella S1 pulls out the main umbrella P1, the line L1, and the riser R1 in the container, and opens the umbrella after a predetermined time.

After the main umbrella P1 is opened, when the personnel M1 suspended from the riser R1 pulls one of the four risers R1, the portion of the main umbrella P1 on the riser side is deformed and the drag force and the like change. Therefore, 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, the parachute shown in FIG. 4 does not have the guiding umbrella and the lip cord like the parachute shown in FIG. 3, but instead, the automatic umbrella ring AR is provided on the main umbrella P1 via the automatic rope CW. It is connected.

The automatic rope ring AR is adapted to be hooked on an automatic rope ring rail (not shown) provided in the upper part of the machine before it descends. When personnel M1 jumps out of the aircraft,
The main umbrella P1, the line L1 and the riser R1 are pulled out from the container by the automatic rope CW. When the main umbrella P1 is pulled out from the container, the separating portion (not shown) of the automatic rope separates,
The main umbrella P1 is automatically opened after a predetermined time (automatic rope-opening system).

The operation after opening the umbrella is the same as that of the parachute shown in FIG.

On the other hand, a control line CL provided separately from the riser R1 and operated by pulling the control line CL has been developed (for example, a paraglider).

FIG. 5 is an external view of a control line control type parachute (hereinafter referred to as "B type").

The parachute shown in the figure has a main umbrella P2 having a wing-shaped cross section and a quadrangle, and a connecting cord CW on the top of the main umbrella P2.
A plurality of lines L2 connected to each other, a plurality of lines L2 whose upper ends are connected to the outer peripheral portion of the main umbrella P2, and a plurality of lines L2.
The four risers R2 that are divided and bundled are connected to the ends of the main umbrella P2, extended to the hands of the personnel M2, and toggled at the lower end TG.
Has a control line CL attached thereto.

As with the parachute shown in FIG. 3, the personnel B of the B type parachute has a lip cord RC.
The umbrella is designed to be opened by pulling (free fall descent system).

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 force is changed. Therefore, the parachute turns in the direction of pulling the control line CL.

That is, this parachute is adapted 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.

In the above description, the parachute can be classified into two types, A type and B type, depending on the operation system, and can be classified into two types, the free-falling descent opening system and the automatic rope opening system by the opening system. 2, the host computer 36
If the type “A type” is input to the riser 24 and the strain gauge SR, the output signal of the strain gauge SR is input to the host computer 36. Further, when the type “B type” is input to the host computer 36, the riser 24, the control line 26, and the encoder SC are used as shown in Table 1. Therefore, the host computer 36 includes an encoder. The SC output signal is input.

Next, the operation of the embodiment will be described.

First, before the training, the instructor sets the contents of the failure training in the host computer 36 of the instructor's room 29 in advance. Here, the parachute failure will be described.

The major failures of the B type parachute (FIG. 5) are listed.

The state where the guide umbrella S2 is entangled with the trainee 23 or does not come out of the container.

The state where the guiding umbrella S2 is not functioning.

The state where the main umbrella P2 does not come out of the container.

The state where the main umbrella P2 does not expand.

The state where the main umbrella P2 is inflated incompletely.

The state where the slider SL does not move down from the top.

The state where the control line L2 is cut off.

The state where the riser R2 is cut off.

The state in which the riser R2 is twisted.

The state where the main umbrella P2 is cracked or torn.

The main failures of the A type (FIG. 4) parachute are listed.

The state where the main umbrella P1 is a non-open umbrella.

-Abnormal open state-Failure open state (damage of main umbrella P1, disconnection of riser R1) As described above, there are various parachute failures.
This simulator targets a partial failure of the main umbrella due to a parachute failure. This is because it is difficult to strictly distinguish and simulate each main umbrella failure, and the method shown below is used.

(1) A shock is given to the trainee in order to recognize the occurrence of the failure of the main umbrella.

(2) Simulate a simple motion such as a sudden descent or a turn.

(3) The status of the main umbrella failure is displayed on the monitor 110 in text or video (characters indicate the type and status of the failure, and the video shows a moving image or still image of the main umbrella P1 (P2) at the time of failure. Use).

First, the failure training of the parachute of type B (FIG. 5) of the free-fall umbrella system will be described. still,
FIG. 6 is an explanatory diagram for explaining the parachute failure training of the free descent opening system and B type, and FIG. 7 is a diagram showing the operation of the failure generation means shown in FIG.

After the floor 101 slides in front of the gantry 21 (on the side of the screen 27), the trainee 23 makes the riser 24
Are attached to the shoulders, and the leg support cords 100 are attached to both feet. When the trainee 23 becomes horizontal (FIG. 6A), an instructor (not shown) in the instructor room 29 returns the floor 101 to the original position and the failure training is started. The trainee 23 carries a simulated container DC on his back to give a realistic feeling. The simulated container DC has the same size and weight as an actual container, but the parachute may not be built therein.

When the training is started, the trainee 23 pulls the lip code LC in the skydiving state to perform the main umbrella opening operation. The signal generated by this operation is displayed and recorded on the instructor desk of the instructor section 29. When the host computer 36 detects the operation of opening the main umbrella with a sensor (not shown), the leg support cord 100 is released.

At the same time when the trainee 23 shifts from the horizontal state to the vertical state, the air cylinder 105 is operated to rapidly contract the piston rod 105a (see FIG. 6).
(A), (b)) The apparent length of the riser 24 (the distance from the overhanging portion 22 to the trainee 23) is suddenly lengthened, so that the trainee 23 is given a shock during a sudden descent.

By operating the air cylinders 103 and 104 and swinging the trainee 23, it is possible to experience a lateral or longitudinal impact.

By displaying the turning image on the screen 27, the trainee 23 can experience the turning feeling. Monitor 110
Since the failure status is displayed in text or video on, the trainee 23 can grasp the status of the parachute failure. This display is operated by the instructor (Fig. 6 (b)).

The trainee 23 takes necessary measures after recognizing the situation of the parachute failure. When the countermeasure cannot be met, finally disconnect the main umbrella and pull the lip code of the spare umbrella to open the spare umbrella (not shown) that is attached in advance. The operation of disconnecting the main umbrella and opening the reserve umbrella is detected by a sensor (not shown), and the signal from the sensor can be displayed and recorded at the instructor's desk.

When the lip cord of the spare umbrella is pulled, the air cylinder 105 operates and the piston rod 105a extends. When the piston rod 105a extends, the riser 2
4 rises, the trainee 23 returns to the normal training position, the control line 26 descends to the trainee 23's hand, and the parachute failure training ends. (FIG.6 (c)).

Description will be made on the case of the failure training of the automatic chute opening type A type (FIG. 4) parachute. Note that FIG.
[Fig. 3] is an explanatory diagram for explaining failure training of an A-type parachute of an automatic rope-opening system.

In this case, the leg support cord 100 is not used. The trainee 23 mounts the riser 24 on the floor 101, and then jumps off the floor 101 (FIG. 8A).

At the same time as the trainee 23 jumps out of the floor 101, the piston rod 105a of the air cylinder 105 is contracted to sharply lower the riser 24 to give a shock to the trainee 23 or the air cylinders 103, 10 as described above.
4 is operated to give the trainee 23 a rocking motion. An image simulating a steep descent or a turn is displayed on the screen 27. The status of the parachute failure is displayed on the monitor 110 in text or video. This display is operated by the instructor.

The trainee 23 recognizes the situation of the parachute failure, takes necessary countermeasures, and finally pulls the lip code of the spare umbrella to open the spare umbrella. The signal from the operation of opening the reserve umbrella is displayed and recorded on the instructor's desk (FIG. 8 (b)).

When the trainee 23 pulls the lip cord of the spare umbrella, the air cylinder 105 operates and the piston rod 105a extends, the trainee 23 is pulled up to the normal position, and the parachute failure training ends (FIG. 8
(C)).

As described above, according to the present embodiment, the parachute failure can be simulated by causing the host computer 36 to operate the failure generation means 19 according to the set failure status. That is, the trainee 23 can experience a sudden descent by operating the air cylinder 105, can experience a lateral impact by operating the air cylinder 103, and can experience a longitudinal impact by operating the air cylinder 104. . The turning state can be experienced by displaying the turning image on the screen 27.

Further, by using the leg support ropes 100, a parachute failure from a skydiving state can be simulated. Further, by using the slidable floor 101 on which the trainee 23 stands by on the pedestal 21, it is possible to experience the parachute failure training when jumping down.

When the trainee 23 is swung, the monitor 1
Since the status of the failure can be grasped by 10 and the processing according to the status of the failure is performed, it is possible to experience the parachute failure when the parachute is opened.

In this embodiment, the free descent umbrella type B type parachute and the automatic rope opening type A type parachute have been described. However, the present invention is not limited to this. The same effect can be obtained in the case of the A type parachute of the formula. Further, although the air cylinder is used as the failure generating means in the present embodiment, the invention is not limited to this and a solenoid may be used.

[0080]

In summary, according to the present invention, the following excellent effects are exhibited.

(1) The suspension means for suspending the descent trainer is oscillated to generate a failure when the parachute is opened, and the content of the failure is displayed to the descent trainer. It is possible to make a descent trainer experience a simulation.

(2) When the leg support means for holding the descent trainer horizontally and holding it in the skydiving state is provided, it is possible to perform the failure training at the time of opening the parachute of the free descent open umbrella system. it can.

(3) When the platform is provided with a slidable floor on which a descent trainer stands by, failure training can be performed when the parachute of the automatic rope-opening system jumps down (when the parachute opens). .
