BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile transport vehicle equipped with a shock absorbing device for shock absorption.

0002

[Prior Art] An underwater separation type transport vehicle (hereinafter referred to as a "flying object") is accelerated by a propulsion device, flies through the air at high speed, and separates the propulsion device in the air. After that, the capsule plunged into the water with the vehicle still inside,
It then attempts to separate the vehicle from the capsule.

[0003] When a capsule plunges into water, very large impact and water resistance forces are generated on the capsule. As shown in FIG. 5, a conventional flying object has a structure between the restraint mechanism 3 that fixes the moving object 1 and the capsule 2 so that the impact force and water resistance force are not directly applied to the moving object 1. A buffer device 4 is provided.

[0004] This shock absorber 4 is designed to protect the capsule 2 and the vehicle 1.
The buffering function is achieved by the relative movement of The vehicle 1 and the capsule 2 will interfere. Therefore, in the past, a space 7 as shown by hatching was provided in front between the flying vehicle 1 and the capsule 2, as shown in FIG. 6, even before the flying vehicle was launched.

As mentioned above, FIG. 5 is a schematic diagram of the state in which a conventional capsule flies through the air and plunges into the water surface 8, where (a) shows the state in flight and (b) shows the state in which it enters the water. FIG. When moving from state (a) to state (b), the capsule 2 is moved by impact force and water resistance force 9.
is suddenly decelerated, while the vehicle 1 moves forward (downward in the figure) due to the inertia force 10, the relative distance between the shock absorber 4 and the restraint mechanism 3 in the axis direction increases, and a shock absorbing effect is exerted. At this time, the space 7 in front in (a) disappears due to the movement of the vehicle 1.

FIG. 6 is a side sectional view of the projectile before launch.
6 is a propulsion device.

[0007]

[Problems to be Solved by the Invention] The above-mentioned conventional flying vehicle (vehicle transporting flying vehicle) had the following problems to be solved.

That is, in a conventional spacecraft, if there is a length restriction on the overall length of the spacecraft, the length of the propulsion device is shortened by the space in front between the spacecraft and the capsule. .

[0009] If the propulsion device becomes shorter, the total thrust will inevitably become smaller if the diameter remains the same, resulting in problems such as the distance the projectile flies will become shorter and the time it takes to reach the destination sea area will become longer. be.

[0010] Therefore, the space in front of the vehicle and the capsule needs to be made as small as possible.

[0011] The present invention solves the above-mentioned problems, and has a large total thrust that does not have the above-mentioned space while functioning as a flying object, but creates a space when the propulsion device is separated and becomes a capsule. The purpose is to provide a flying object.

0012

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention provides a method for attaching a propulsion device for flight in a detachable manner to a capsule containing a propelling object, and after flying in the air by the propulsion device, the propulsion device In a vehicle transporting vehicle that separates the vehicle from the capsule and plunges into the water to separate the vehicle from the capsule and travel, a vehicle is provided in front between the capsule and the vehicle so that the vehicle can be moved. Before the separation of the space and the propulsion device, the craft that had previously moved into the space is moved backwards after the separation of the propulsion device to free up the space, and upon landing on water, moves toward the space again by the impact force. It is an object of the present invention to provide a vehicle transporting vehicle characterized by being equipped with a shock absorbing device for cushioning the vehicle.

[0013]

[Operations] Since the present invention is constructed as described above, it has the following functions.

That is, before the propulsion device is separated, the main vehicle carrying vehicle transports the vehicle, which has moved in advance into the space provided in front between the capsule and the vehicle, from the propulsion device. After separation, the vehicle is moved backwards to free up the above space, and when it lands on water, it is equipped with a shock absorber that cushions the vehicle, which moves toward the space again due to the impact force. However, the space required for movement to be buffered by the shock absorber is provided in front between the capsule and the vehicle, and the vehicle is protected from the impact of landing on water.

On the other hand, before the propulsion device is separated, the vehicle is moving (advancing) in the space, and there is no restriction on the length of the propulsion device in the propulsion direction. Therefore, the propulsion device can be made longer by the length of the space, compared to the conventional example in which a space is maintained in front of the capsule and the vehicle even before the propulsion device is separated. That is, the total propulsive force can be increased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First and second embodiments of the present invention will be explained with reference to FIGS. 1 to 4. Note that the same reference numerals are given to the same constituent members as in the conventional example, and the explanation thereof will be omitted.

First, a first embodiment will be explained with reference to FIGS. 1 and 2. FIG. 1 is a side cross-sectional view of a flying vehicle (vehicle carrying vehicle) according to this embodiment, and FIG. 2 shows the state in which the propulsion device 6 is separated from the state shown in FIG. It is a diagram showing a state in which a space 7 is created by moving relatively backward.

In both figures, the restraint mechanism 3 and the shock absorber 4a
A spring 5a is inserted as a member of a shock absorber 4a as a driving means for moving the flying object 1, and as shown in FIG. 1, the spring 5a is compressed when the flying object is assembled. The propulsion device 6 is attached to the capsule 2 in such a state that the vehicle 1 is pushed forward and the space 7 in front between the vehicle 1 and the capsule 2 is eliminated.

When the propulsion device 6 separates after launching the projectile, the rear end of the capsule 2 is released and the rear end of the vehicle 1 is no longer restrained, so the force of the spring 5a causes the vehicle 1 to slides rearward with respect to the capsule 2, and a space 7 is created in front between the vehicle 1 and the capsule 2, as shown in FIG. As a result, the impact when entering the water causes the vehicle 1 to move between the spaces 7, and the shock absorber 4a is activated.
That is, the spring 5a and the like are compressed, and the mobile vehicle 1 is buffered.

Next, a second embodiment of the present invention will be explained with reference to FIGS. 3 and 4. The second embodiment is similar to the first embodiment except that a gas generator is used as a driving means for the shock absorber 4b. FIG. 3 is a side sectional view of the flying object according to this embodiment, and FIG. 4 shows the propulsion device 6 separated from the state shown in FIG. It is a diagram of a state in which a space 7 is created by moving backward.

In both figures, a gas generator 5b capable of supplying gas pressure to the airtight expansion/contraction means between the restraint mechanism 3 and the shock absorber 4b is provided in (the front of) the shock absorber 4b. It is configured to operate when the propulsion device 6 is separated. Therefore, the assembled state, ie, Fig. 3
In the state shown in FIG.
When the propulsion device 6 is separated as shown in FIG.
is activated, the restraint mechanism 3 retreats relative to the shock absorber 4b, that is, the vehicle 1 retreats relative to the capsule 2,
A space 7 is created.

When landing on water, the shock absorber 4b operates against the relative forward movement of the vehicle 1, and the gas pressure generated from the gas generator 5b resists the movement of the restraint mechanism 3 with the required force to provide a shock absorbing effect. Fulfill.

As described above, according to the first and second embodiments,
While the projectile is flying by the propulsion device 6, the capsule 2
On the other hand, the vehicle 1 is pushed forward and occupies the space 7, and when the propulsion device 6 separates from the capsule 2, the vehicle 1 moves relatively backward and occupies the space 7. cause
Since it creates a buffer movement allowance when landing on water, the length of the propulsion device 6 can be increased by the length of the space 7 in the axial direction, compared to the conventional example. Since the thrust is increased, there is an advantage that the flying distance of the projectile can be increased or the time required to reach the target sea area can be shortened.

Note that in the first and second embodiments, the shock absorber 4
Although the spring 5a and the gas generator 5b are used as the means for moving the vehicle 1 by means of a and 4b and the buffer means, the present invention is not limited to these two means, and any other suitable means may be used. Good too.

[0025]

Effects of the Invention Since the present invention is constructed as described above, it has the following effects.

That is, the front part between the capsule and the vehicle,
The vehicle is moved (forward) in the space provided for the movement of the vehicle before the propulsion device is separated, that is, during flight, and the vehicle is moved forward after the propulsion device has finished flying and the propulsion device has been disconnected. Since the body is moved backward to create a space and prepare for buffering when landing on water, the present invention does not require an extra space length compared to the total length of the vehicle transport vehicle in the past.
Therefore, the length of the propulsion device can be increased by that much. As a result, the propulsion force increases, making it possible to extend the flight distance or shorten the time it takes to reach the destination sea area.
