1 to 6, the drop training simulation apparatus 100 according to an embodiment of the present invention is the support frame 110, the drive unit 120, the support unit 130, the string unit 140, the pulley The unit 150 and the control unit (C).

The support frame 110 is a component that is fixed to the installation surface to support other components with respect to the installation surface. In this embodiment, the support frame 110 includes a pair of vertical frames 112 and a pair of vertical frames. It may include a horizontal frame 114 disposed between the (112).

The controller C may be built in the support frame 110 or may be installed outside. The controller C has various programs for operating the driver 120 to be described later and the puller 150 to be described later, and the program is executed according to various signals input to the controller C to drive the driver 120 or the pulley. The unit 150 may be controlled.

The driving unit 120 is disposed between the horizontal frame 114 and the support 130 to adjust the inclination and height of the support 130 according to the signal output from the controller (C). In general, the driving unit 120 is a device that gives a real experience to the trainer 10 in a directed situation, and the driving unit 10 actually races a car or boards a fighter by an operation in which the driving unit 120 is tilted or raised and lowered. You can experience like this. To this end, the motions that can be felt when the actual car race or aboard a fighter are implemented using mechanical degrees of freedom. The driving force for moving the driving unit 120 may be generally used for hydraulic pressure, electric motor, and pneumatic pressure.

Specifically, the driving unit 120 according to the present invention, which delivers the human body response similar to the actual drop training to the trainer 10, is connected to the support 130 as a motion base consisting of six actuators 122. The front end of the actuator 122 is connected to the horizontal frame 114 is installed downward. The horizontal frame 114 side is stably supported by the outer support frame 110.

The six actuators 122 are configured to form three pairs in pairs so that the ends are connected to each other with the lower end connected to the horizontal frame 114. Here, the tip of the three sets of actuators 122 is made of three points in a triangular shape in a plan view, such as a connection part of the driving part 120 and the support part 130, and is connected to three points of the support part 130 by a hinge axis. .

In the present invention, a motion base consisting of six actuators 122 has been described as an embodiment, but is not limited thereto. For example, a four-axis, eight-axis, or nine-axis drive driver 120 may be applied.

Alternatively, a motor (not shown) may be applied to the driving unit 120 so that the support unit 130 may vibrate or impact the support unit 130 according to the operation of the motor (not shown). Since the driving unit 120 is a known technique, detailed description of the configuration will be omitted.

The support 130 is installed in the horizontal frame 114 to be parallel to the installation surface in the initial state. In addition, the support 130 may adjust the inclination and height by the driving unit 120 to transmit the human body response similar to the operation of the actual parachute by the operation of the driving unit 120 to the trainer 10. The shape of the support 130 may be variously formed, such as a triangle or a circle, such as triangular, square, hexagonal.

The string unit 140 may include a first string 142 and a second string 144. The first string 142 is originally connected to the parachute and the harness 20 constituting the actual parachute. In one embodiment, one end of the first string 142 is connected to the bottom of the support 130 and the other end is connected to the harness 20 worn by the trainer 10. In general, the first string 142 may be connected to the shoulder portion of the trainer 10. In this case, the first string 142 may be a parachute riser.

In this embodiment, the second string 144 has one end connected to the bottom surface of the support 130 and the other end connected to other body parts except for the shoulder of the trainer 10. Although the second string 144 is illustrated as an example in which the second string 144 is connected to the leg of the trainer 10, the second string 144 may be connected to another part such as the waist of the trainer 10.

In general, four first strings 142 are provided, and the second string 144 may be connected to each of the legs of the trainer 10. However, the number of the first string 142 and the second string 144 is not limited to those described above, and the number of the first string 142 and the second string 144 may be as long as it can stably support the trainer 10 and smoothly adjust the body of the trainer 10. It can be provided without regard.

Accordingly, the operation of the driving unit 120 is transmitted to the trainer 10 through the string unit 140 including the first string 142 and the second string 144 via the support 130, so that the trainer 10 may be transferred to the trainer 10. From the actual aircraft or helicopter jumps, the descent of the jump, the descent of the descent, the deployment of the parachute, and the landing can be carried out on the ground as if it were real.

In the present embodiment, a control line (not shown) for adjusting the parachute may be further included. In this case, the control line (not shown) is connected to a wired / wireless sensor (not shown), and thus, when the control line (not shown) is pulled, a wired or wireless sensor (not shown) is used. ) Detects this and sends a signal to the controller C which controls the driver 120. The controller C receiving the signal is programmed to move the parachute, such as when pulling the actual parachute control line (not shown), so that the actual parachute movement corresponding to the signal of the wired / wireless sensor (not shown) is performed by the driving unit 120. The operation of the driving unit 120 is controlled.

For example, since the human body response similar to the shaking, rolling, pitching, impact, and rotation of the actual parachute is transmitted to the trainer 10 through the operation of the driving unit 120 under the control of the controller C, the trainer 10 trains the actual drop. You can experience like this.

Meanwhile, the pulley 150 may include a first pulley 152 that adjusts the length of the first string 142 according to rotation and a second pulley 154 that adjusts the length of the second string 144 according to rotation. Include. here. The first pulley 152 is installed on the support 130. In addition, although the second pulley 154 is installed in the support part 130 as an example in the drawings of the present embodiment, the second pulley may be installed on one side of the support frame 110 in addition to the support part 130.

The first pulley 152 and the second pulley 154 are separately controlled by the control unit (C) to adjust the inclination or height of the body of the trainer 10, or to apply an impact to the body of the trainer 10. I can regulate it. As a result, the trainer 10 may reproduce various situations that may occur when the actual fall.

For example, when the trainer 10 jumps and falls, the first pulley 152 and the second pulley 154 operate to lift the trainer 10 into the air, and then support the trainer 10 with the support portion ( 130).

To this end, the harness 20 is provided with a box-shaped insertion box 30 that is in close contact with the back of the trainer 10, the support 130 is coupled to the receiving groove 134 is formed to accommodate the insertion box 30 The member 132 may be provided.

As a result, the trainer 10 is lifted into the air so that the insertion box 30 is accommodated in the receiving groove 134 so that the trainer 10 is fixed to the support 130, and the trainer 10 attaches the body to the coupling member 132. As close as possible to the movement of the above-described support 130 may be transmitted to the trainer 10.

At this time, a blower (not shown) for generating wind to the trainer 10 side from the lower and side of the trainer 10 so that the trainer 10 can experience the actual falling situation more realistically. As such, when the trainer 10 descends, the upward wind is generated from the lower portion of the trainer 10 to give the trainer 10 a feeling of gliding in high altitude.

Alternatively, the length of the first string 142 may be longer than the length of the second string 144 to practice the strong posture that the upper body of the trainer 10 is lower than the lower body.

The harness 20 may be connected to a switch string (not shown) that expands the parachute, and may be exposed to the outside. When the trainer 10 pulls the switch string (not shown) during the strong practice, the first pulley 152 may be wound. At the same time, the second pulley 154 can be released rapidly.

That is, as the length of the first string 142 is slightly shortened and the length of the second string 144 connected to the legs of the trainer 10 is rapidly lengthened, the lower body of the trainer 10 may drop rapidly. In this case, an impact may be applied to the upper body of the trainer 10.

In this way, by controlling the first pulley 152 and the second pulley 154, the trainee by the impact applied to the body of the trainer 10 when the parachute is deployed during the actual fall, the gusts or collision during the actual fall It is possible to reproduce various shock situations that may occur during the actual fall, such as the impact on the body of (10).

In addition, during the parachute deployment training by using a blower (not shown) to generate the upwind and transverse wind at the bottom and side of the trainer 10 can enable the trainer 10 to experience the feeling of parachute deployment vividly.

The controller C is programmed with a suitable motion when a signal other than the above-described operation is input. Accordingly, the trainer 10 operates the first pulley 152, the second pulley 154, and the driver 120. There are a variety of falling experiences.

On the other hand, the emergency escape training apparatus of the present embodiment may be further provided with a simulation image playback unit 160 to increase the realism. Here, the simulation image reproducing unit 160 may include a virtual reality (VR), a goggle with a built-in monitor, a large screen provided on the front of the trainer 10, or a plurality of monitors surrounding the trainer 10. In this way, the trainer 10 can be given a sense of realism such as training in a high altitude.

The simulation image reproducing unit 160 may be electrically connected to the control unit C to reproduce an image according to a training situation. When a signal suitable for an image being reproduced is input from an external input device, an image corresponding to the input signal may be reproduced.

For example, during the drop training using the drop training simulation apparatus 100 of the present embodiment, the simulation image reproducing unit 160 may reproduce the aircraft image before the drop.

When the trainer 10 jumps and the trainer takes a strong position at a certain point in time, the simulation image reproducing unit 160 may play a sliding image. When the trainer 10 performs the operation of deploying the parachute, the lower body of the trainer 10 drops sharply, and the simulation image reproducing unit 160 may reproduce the image of the parachute deployed.

Here, the simulation image reproducing unit 160 may be linked with the driving unit 120 by the controller C so that the driving unit 120 may transmit vibrations, shocks, tilts, etc. corresponding to the simulation image to the trainer 10.

In the above, the drop training simulation apparatus 100 according to an embodiment of the present invention has been described.

Hereinafter, a drop training simulation method according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6.

Drop training simulation method according to an embodiment of the present invention as a method of drop training using the drop training simulation apparatus 100 according to an embodiment of the present invention, comprising a preparation step, a support step and an experience step.

As shown in FIG. 1, in the preparation step, the trainer 10 wears the harness 20 connected to the support 130 by the first string 142, and connects the second string 144 to the leg.

As shown in FIG. 2, when the trainer 10 jumps in the flotation stage, the first pulley 152 and the second pulley 154 are rotated to wind the first string 142 and the second string 144. Lift the trainer 10 into the air.

In the experience stage, the first pulley 152, the second pulley 154, and the driving unit 120 are operated to change the body tilt or height of the trainer 10, or the impact applied to the body of the trainer 10. By adjusting the controller 10 reproduces various situations that may occur when the actual fall.

More specifically, the experience step may include at least one of a downhill process, a parachute deployment process, and a landing process.

The sliding process is a process of experiencing a feeling of sliding in the high air, and as shown in FIG. 3, the first pulley 152 and the second pulley 154 in a state in which the trainer 10 is lifted up in the air during the support phase. In operation, the first string 142 and the second string 144 may be adjusted to be shorter to bring the trainer 10 into close contact with the support 130.

At this time, the insertion box 30 connected to the harness 20 of the trainer 10 is inserted into the receiving groove 134 to fix the body of the trainer 10 to the support 130, and then embedded in the controller C. When the running program is performed, the controller C may operate the driving unit 120 to reproduce the actual movement during the downhill run. As a result, the trainer 10 may receive the movement of the support 130. At the same time, the simulation image reproducing unit 160 may reproduce an image in which the trainer actually falls. In addition, the driving unit 120 may reproduce the shock and vibration corresponding to the image.

In addition, by generating an upward wind in the lower portion of the trainer 10 with a blower (not shown), the trainer 10 may feel a sense of buoyancy, and thus may feel a glide in high air. The parachute deployment process is a process of expanding the parachute by pulling a switch string (not shown) when it reaches a certain altitude during descent and experiencing a shock applied to the body when the parachute is unfolded, as shown in FIG. ) Can first take a strong position. At this time, the length of the first string 142 is adjusted to be longer than the length of the second string 144 by releasing the first pulley 152 so that the upper body of the trainer 10 lifted into the air is positioned lower than the lower body.

And, as shown in FIG. 5, when the trainer 10 pulls a switch string (not shown) exposed to the outside, the first pulley 152 winds up the first string 142 to slightly lift the upper body of the trainer 10. At the same time, the second pulley 154 is suddenly loosened and the length of the second string 144 is increased, so that the lower body of the trainer 10 may drop rapidly.

At the same time, the simulation image reproducing unit 160 may reproduce an image in which the parachute is deployed. In addition, the driving unit 120 may reproduce the shock and vibration corresponding to the image.

In this way, an impact similar to when an actual parachute is deployed to the body of the trainer 10 may be applied. In the parachute deployment process, a blower (not shown) may generate an upward wind mill cross wind to the trainer 10 to vividly experience the feeling of the actual parachute deployment.

Landing process is a process of experiencing the operation and feeling, such as adjusting the parachute from the parachute deployment to landing, as shown in Figure 6, during the landing process, the trainee 10 is standing up and floating in the air control line (not shown) When the control unit (not shown) connected to a control line (not shown) is sent to the control unit (C) for controlling the driving unit 120, a parachute may be controlled.

The control unit C is programmed with the movement of the parachute, such as when pulling the actual parachute control line (not shown), so that the driving unit 120 performs the movement of the actual parachute corresponding to the signal of the wired / wireless sensor (not shown). ) Can be controlled. For example, since the human body response similar to the shaking, rolling, pitching, impact, and rotation of the actual parachute is transmitted to the trainer 10 through the operation of the driving unit 120 under the control of the controller C, the trainer 10 trains the actual drop. You can experience like this. At the same time, the simulation image reproducing unit 160 may reproduce an image coming down from the air on a parachute, so that the image of the trainer 10 may be controlled by controlling the control line.

After a certain time, when the simulation image playback unit 160 reproduces the landing image and the parachute movement experience is completed, the controller C releases the first pulley 152 and the second pulley 154 to release the first string 142. ) And the length of the second string 144 may be increased to allow the trainer to land on the installation surface.

In the above, the drop training simulation process according to an embodiment of the present invention has been described.

As described above, the preferred embodiments of the present invention have been described, and the fact that the present invention can be embodied in other specific forms in addition to the above-described embodiments without departing from the spirit or scope thereof has ordinary skill in the art. It is obvious to them. Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above description and may be modified within the scope of the appended claims and their equivalents.
