Description

[Detailed description of the invention] Technical field This invention relates to an ejection seat simulator.

BACKGROUND OF THE INVENTION Various ejection seat simulators are used for training pilots of jet aircraft. Generally, these simulators are configured for training flight crews, and training for ejection procedures from an aircraft and training for the large gravitational force that is applied during ejection. For example, there are simulators, such as those disclosed in US Pat. No. 2,467,764, in which a seat is mounted to move along a test rig guide. Additionally, the Naval Training Equipment Center (Naval Training Equipment Center)
ipmentcenter) is the Universal Ejection Seat φ Trainer (llniversal
Ejection 5eat rainer), 9E
6, and Burchik Incorporated (Bu
There is a simulator sold by rtck, Inc.), but this simulator is for cockpit use.
Seats are attached to upright towers. A track member is attached to the upright tower, and the seat is ejected from the cockpit along this track member.

Since a large inertial force is applied to the body of a passenger undergoing training while sitting in a seat, various precautions are taken to prevent the seated position of a passenger undergoing cockpit ejection training from shifting. However, even with precautionary measures, accidents still occur. For example, if the seating position of the passenger is not appropriate, there is a risk that the passenger may be injured when the seat is ejected from the cockpit. In such cases, passengers must be removed from the cockpit after the ejection seat has been returned to its original position within the cockpit. However, since the conventional cockpit is of a fixed position type, it is not possible to easily approach the seated passenger. This is particularly problematic when passengers require careful handling for medical reasons. Additionally, the cockpit may be located higher than the ground. In such a case, it is more difficult to approach the passenger, and in particular it is not easy to bring a rescue device such as a gurney (a bed with wheels) or a motorized emergency vehicle alongside the passenger. Furthermore, if it is necessary to change the seat to suit the aircraft in question, a cumbersome operation is required to remove the seat from the cockpit and replace it with another seat.

OBJECT It is an object of the present invention to provide an ejection seat simulator that allows easy access to passengers in the event of an accident.

Another object of the invention is to provide an ejection seat simulator that allows the seat to be easily replaced, modified or repaired.

Another object of the invention is to provide an ejection seat simulator that allows access to the passenger on the ground.

Another object of the present invention is to provide an ejection seat simulator that is relatively simple in structure and allows for easy ejection training on aircraft boarding pages.

Another object of the invention is to provide an ejection seat simulator that is easily interchangeable to suit the type of aircraft being simulated.

SUMMARY OF THE INVENTION The ejection seat simulator of the present invention includes a tower having a support base and a track member extending upwardly from the support base, a seat attached to the track member for movement along the track member, and a seat mounted on the track member for movement along the track member; and a first device for propelling the track member along the track member. moreover,
The cockpit is removably attached to the support stand. The cockpit is movable between a first position adjacent the support and surrounding the seat and a second position away from the support and the seat to open the seat.

A device for simulating a series of injection operations is installed in the cockpit, and a device for activating the propulsion device upon completion of the series of injection operations is installed in the seat. An electric control panel is connected to both devices installed in the cockpit and seats, and signals from both devices are sent to this control panel.

Additionally, the control panel is connected to the propulsion system and operates the propulsion system in response to signals from both the cockpit and seat-mounted systems.

The devices installed in the cockpit include a dummy throttle for deceleration simulation and a tension ring for canopy breakaway simulation. Additionally, a signal device is installed in the cockpit to indicate when the injection operation has started.

In order to removably connect the cockpit to the support base, a pair of alignment pins are attached to the support base, and holes are formed in the cockpit into which the alignment pins can be inserted. The cockpit is mounted via rollers on rails laid on a concrete floor adjacent to the support base. Therefore, the cockpit can be moved toward and away from the support base as needed. Furthermore, a clamping member is used to releasably lock the cockpit to the support. This tightening member consists of a vertical hook attached to the support base and attached to the rear of the cockpit.
and a latch that can be engaged and detached from the hook.

The seat propulsion system includes a heel pad switch.

This switch is actuated by the occupant's foot and therefore indicates whether the foot is in a predetermined position. A switch is also installed near the passenger's head to indicate whether the passenger's head is in a predetermined position. Additionally, a tension ring or D-ring is attached to the seat.
When the passenger pulls on it, the ejector is activated and the seat is ejected. In addition, the face curtain (
raca curtain) can also be used.

This simulator is configured so that the cockpit is flush with the floor, so passengers can climb over the side walls of the cockpit to reach their seats, or they can move the cockpit out of their seats before reaching their seats. You can also do that. In either case, passengers take their seats, secure the cockpit to the tower, and then begin a series of ejection maneuvers. For example, when a signal device in the cockpit indicates that an ejection operation has begun, the passenger holds a dummy throttle to simulate deceleration, and then operates a tension ring to simulate canopy departure.

Immediately after the invasion, he pulls his foot closer, activating the heel pad switch to indicate that his foot is in position, and then activates the head switch with his head, indicating that his head is in the correct position. Finally, pull the tension ring attached to the seat to activate the propulsion system.

By performing the above sequence of operations, the seat is normally ejected along the track.

In the event of an accident during ejection, the seat can be returned along the track into the cockpit, and then the cockpit can be moved away from the support platform, allowing easy access to the passengers. Therefore, when it is necessary to remove the passenger using a gurney or the like, it is not necessary to lift the passenger and carry him out of the cockpit, making the rescue work easy.

Even if it is necessary to replace the seat, the replacement work can be easily performed by separating the cockpit from the support base.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an ejection seat simulator 10 (hereinafter simply referred to as a simulator) comprises a well-known tower 11. The tower consists of a fixed support 12 and a track 13 extending upwardly from the support 12 at an angle. Note that this ten rack 13 has a well-known structure, so a description thereof will be omitted.

The track 13 of the simulator 10 has a seat 14 mounted for movement along the track 13 in a conventional manner. This seat 14 is a drop WA for the cable device 15 etc.
It is connected to the riB device. The seat 14 is moved by this cable device 15 between a raised position shown by a broken line in FIG. 1 and a lowered position shown by a solid line. This cable device 15 also has a well-known structure, so its explanation will be omitted.

The simulator 10 is equipped with an injection machine 17 (see FIG. 4) for propelling the seat 14 along the track 13. A propulsion device, such as a pneumatic ejection device, is used to eject the seat 14, which ejects the seat 14 along the track 13 from the lowered position to the raised position shown in FIG.

As shown in FIG. 1.3.4, the simulator 10 has cockpits 1 to 18 detachably fixed to a support base 12. This cockpit 18 has a shell-shaped housing 19 installed on a pair of rails 21 via rollers 20. Since the rail 21 is attached to a concrete floor, the cockpit 18 is placed in a first position adjacent to the support base 12 and surrounding the seat 14 (see FIG. 3) and separated from the support base 12 to expose the seat 14. It is possible to operate between the second position (see FIG. 4). In addition, the housing 19
A box 22 is attached to the rear end of the box 22 extending from both sides thereof.

The housing 19 is made of aluminum or the like and weighs approximately 160 bonds (approximately 72 kg).
It can be freely moved along the rail 21. In addition, as a means for moving this housing 19, a handle 23 is attached to a predetermined position of a box 22 attached to the housing 19 and to the front part of the housing 19.

As shown in FIG. 4, a pair of releasable fastening members 24 are used to secure the cockpit 18 to the support base 12. For example, each tightening member 24 is an over-center quick 11iPA latch, which
It consists of a hook 25 fixed to and a latch 26 that can be engaged with the hook 25.

Each latch 26 consists of a pair of arms 27, 28 that pivot and articulate with each other. One arm 27 is rotatably attached to the floor of the cockpit 18 via a bracket 29, and the other arm 28 is freely engaged with the hook 25. As shown, the latch 26 and the hook 25 are set to be locked in the horizontal position of the arms 27,28. If it becomes necessary to quickly move the cockpit 18 from the support base 12 to get closer to the passenger T in the seat 14, the tightening member 24 can be quickly released manually.

A pair of alignment pins 30 are attached to the support base 12. This alignment pin 30 is attached to the side of the housing 19 facing the box 22 and is attached to the side of the housing 19 facing the box 22.
It is inserted into the hole formed in the hole.

As shown in FIG. 2, a device for simulating an injection operation is arranged in the cockpit 18.

These devices are installed inside the side wall of the housing 19 (e.g.
A dummy throttle 31 disposed on the left side of the seat 14 is included. By pulling out the throttle 31, a quick simulation can be performed using the display. Furthermore, a tension ring 32 for simulating canopy detachment is attached to the front panel 33 in the cockpit 18.

By pulling this ring 32, a canopy (not shown) detachment simulation can be performed using the display.

A device is attached to the seat 14 for operating the injection machine 17 by performing a series of injection operations. These devices include a pair of heel pad switches 371.
(see FIG. 4) and a head switch 35. The heel pad switch 34 is attached to the floor surface of the cockpit, and is set to be activated when the passenger T draws his or her feet against the heel pad switch 34. Further, the head switch 35 is attached to the upper end of the seat 14, and is set so that when the passenger T presses his/her head against the head switch 35, it is indicated that the passenger T himself/herself is in the ejection position.

Further devices are attached to the seat 14. This device is, for example, a tension ring 36 placed between the legs of the passenger T in the center of the seat 14 (see FIG. 2). When this tension ring 36 is pulled, the injection machine 17 is actuated and the seat 14 is ejected upward along the track 13.

As shown in FIG.
is installed. This control panel 37 is for the instructor to operate, and is installed apart from the tower 11 and cockpit 18. As shown in FIG. 6, this control panel 37 is connected via conductive wires 38, 39 to the throttle 31, tension ring 32 and heel pad switch 34 in the cockpit, and to the seat head switch 35 and tension ring 36. , receive signals emitted from these.

Further, since the control panel 37 is connected to the injection machine 17, this injection machine 17 is operated in response to signals from the cockpit 18 and the seat 14.

For example, since the control panel 37 is provided with a start switch 40, the instructor can
0 activates a signal device such as a starting lamp 41 attached to the front panel 33 of the cockpit 18,
It is possible to notify the passenger of the start of the injection operation with a signal. Since the throttle 31 in the cockpit 18 and the circuit in the control panel 37 are connected by a suitable circuit device, a signal is sent to the throttle 31. When the throttle 31 is pulled back, the pilot lamp 31a lights up. The tension ring 32 in the cockpit is also connected to a similar circuit, and when the tension ring 32 is fully pulled out and the canopy is removed, the pilot lamp 32 of the control panel 37
2a is lit. Similarly, each heel pad switch 3
4 and the head switch 35 are connected by a suitable circuit device, a signal is transmitted to the panel 37, and the pilot lamp 34a of the panel 37 is activated accordingly.

35a is lit. Note that if it is desired to set the position of the passenger's head more accurately, a pair of head switches (not shown) may be used. In that case, one pair of circuits is used for each switch. A pilot light is also used to indicate when the switch is closed.

The control panel 37 has a circuit connected to the circuit leading to the tension ring 36, and receives a signal from the tension ring 36 to turn on the lamp 36a of the panel 37.

When all circuits and their corresponding lamps are activated and proper operation is in progress, the injection machine 17 is operated by a tension ring 36 supplied via a control panel 37.
activated by a signal from

An override safety switch 42 that is operated by an instructor is attached to the control panel 37. If the switch circuits are not activated in the proper order, the safety switch 42 can be operated to stop injection.

Next, the operation of this device will be explained. A passenger T undergoing training sits on a seat 14 and fixes a cockpit 18 to a support base 12 of a tower 11. When the starting lamp 41 attached to the control panel 33 of the cockpit 18 lights up, the passenger T performs a series of injection operations. first,
Pull the dummy throttle 31 and control panel 33
Pull the tension ring 32. Next, the passenger T pulls his/her feet closer to actuate the heel pad switch 34, and uses his/her head to actuate the head switch 35 at the rear. In addition,
As shown in FIG. 1, since the passenger T is wearing a helmet 43, the head switch 35 is connected to the helmet 43.
3.

After completing the above four operations, the passenger T pulls the tension ring 36 disposed in the center of the seat 14.

At this time, the injection machine 17 operates upon receiving a signal from the control panel 37. Then, the seat 14 carrying the passenger is ejected upward (indicated by diagonal lines in FIG. 1). Thereafter, the seat 14 is returned to its original position (indicated by solid lines in FIG. 1) by means of the cable attachment a15.

If the passenger T has to be lowered due to an accident or the like, the two tightening members 24 can be quickly removed and the cockpit 18 can be moved forward along the track 21.
It can be taken down easily.

Note that the conductor 11A 39 connecting the control panel 37 and the cockpit 18 needs to be sufficiently long so that the cockpit 18 can be moved sufficiently.

As described above, the present invention provides an ejection seat simulator that allows pilots to easily perform ejection training. Furthermore, the present invention provides an ejection seat simulator that allows the cockpit to be quickly moved from the seat area to easily approach passengers in the event of an accident.

Note that by making the cockpit 18 rotatable around a horizontal pivot shaft provided at the lower part of its front end, or a vertical pivot shaft provided at its rear, tower 11, or an adjacent corner, this cockpit can be rotated. 18 may be separated from the seat section. The cockpit 18 can also be mounted on the support base 12 if the seat 14 needs to be repaired or replaced.
If they are spaced apart, there will be enough space for this purpose. Similarly, if a different type of cockpit is required, it can be easily replaced.
