When a conventional rocket launching support apparatus is used, a pad drift in a behavioral form accompanied with the lateral movement as described above occurs at the time of launching the rocket. The part interferes with the rocket launching support device, and the nozzle of the rocket is damaged. In order to avoid the occurrence of such a state, it is conventionally unreasonable, but it is necessary to secure a distance (called pad clearance) that can avoid interference between the rocket body and the rocket launching support device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the conventional rocket launching and supporting apparatus, and raises the required distance vertically without laterally moving the rocket at the time of launching the rocket, thereby reducing interference with equipment. It is an object of the present invention to provide a rocket launch support device that is eliminated.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the invention according to claim 1 comprises a locking portion which engages with the rocket body bottom surface to prevent mutual horizontal displacement, and a method for preventing the horizontal displacement. A rocket pushing-up cylinder having a ram that pushes up the rocket via the locking portion, and a vertical guide holding portion that regulates the driving of the pushing-up ram of the cylinder vertically so that the rocket is forcibly applied even after the rocket launches and floats. The rocket is configured to be pushed up vertically.

[0007] By configuring the rocket launching support apparatus in this manner, not only the self-weight support function before launching, but also
It has a function to push the rocket vertically immediately after launch, and it is possible to reliably avoid interference between the launch vehicle and the launch equipment due to pad drift accompanying lateral movement immediately after launch.

[0008]

Next, an embodiment will be described. FIG. 1 shows a first embodiment of a rocket launch support device according to the present invention.
It is a figure showing the whole composition of an embodiment. In FIG. 1, reference numeral 1 denotes a rocket launching support portion, which is fixedly arranged on a ground fixing portion 5 so as to correspond to a plurality of (3 to 4) rocket-side seats 3 provided on the periphery of the bottom surface of the rocket 2. And constitute a rocket launch support device. In FIG. 1, reference numeral 4 denotes a rocket engine nozzle.

Support-side seat 11 having a convex portion 11a formed on its surface.
The receiving seat 11 is connected to the tip of a cylindrical push-up ram 12. Push-up ram 12 is cylindrical support body
It is inserted inside 13 and pushes up the rocket vertically when launching the rocket. For this reason, a pneumatic or hydraulic cylinder portion 14 is formed at the lower portion of the support portion main body 13, and a piston portion 15 provided at the lower end of the push-up ram 12 is provided on the inner wall surface of the cylinder portion 14 via a piston ring 16. The support section main body 13 has an introduction passage for introducing compressed air or oil into the cylinder section 14 at the bottom thereof.
17 is formed, and a compressed air source or a hydraulic pressure source 19 is connected to the introduction path 17 via a valve 18.

On the other hand, the upper portion of the supporting portion main body is partitioned by a partition 21 provided with a packing 20, and a vertical guide portion 22 is provided. When the ram 12 is pushed up when a rocket is fired, the ram 12 is pushed up vertically. It is designed to guide you to 12. Therefore, the vertical guide 22
Has a considerable strength against a lateral load on the rocket such as a wind load, and does not give resistance to the pushing-up operation of the pushing-up ram 12, for example, via a linear ball bearing 23, an outer peripheral surface of the pushing-up ram 12. Is guided vertically.

[0011] Then, the pressure receiving area A = πD ^2/4 of the piston portion 15 of the push-up ram 12 to be fitted in the cylinder portion 14

Mount on top.

At the time of launching the rocket, the injection of the combustion gas from the rocket nozzle 4 is started, and at the same time as the launch timing, the start control valve 18 of the air (oil) pressure cylinder section 14 is opened to release the air (oil) into the cylinder. After the rocket lifts up due to the injection of combustion gas,
The piston section 15 is moved by the amount of the rising stroke of the push-up ram 12.
And pushes up the ram 12 to forcibly push the rocket 2 up.

At this time, the lifting ram 12 is connected to the vertical guide portion 22.
Accordingly, the guide is guided in the vertical direction via the linear ball bearing 23 while being firmly held so as not to move in the horizontal direction. In the rocket 2, the concave seat 3 provided on the bottom face is fitted with the convex seat 11 disposed above the push-up ram 12, so that the rocket 2 does not relatively shift in the horizontal direction. The rocket 2 is pushed up in the vertical direction and rises. Therefore, unlike the related art, the pad drift accompanying the lateral movement immediately after the launch due to the wind or the misalignment of the rocket does not occur, and the interference between the rocket and the launch equipment at the time of launch can be reliably avoided.

As described above, according to the rocket launching support apparatus according to the present embodiment, not only the rocket self-weight supporting function before launching the rocket in the conventional rocket launching support apparatus, but also the rocket just after launching is pushed up in the vertical direction. It has a function, therefore, avoids interference between the rocket and the launch equipment due to pad drift immediately after launch, and furthermore, the pushing force on the rocket due to the pushing operation of the pushing ram increases the acceleration force when launching the rocket It can also contribute to.
