Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying object applied as aerospace equipment.

[0002]

2. Description of the Related Art FIG. 5 is an explanatory view of a conventional flying body used as an aerospace device. In the figure, this flying object is launched from an aircraft or the ground and flies in the air at a supersonic speed by a rocket motor, and when it approaches a target point to a certain extent, a balloon (valuto) 1 is opened and softly watered, The underwater vehicle accommodated in the capsule 3 is driven toward a target. When the balloon 1 is discharged in the air, the airflow naturally flows into the folded balloon 1 from the air intake 1a. It is designed to open aerodynamically.

[0003]

In the conventional flying body as described above, when the balloon 1 is released in the air, the shape of the balloon 1 is freely changed by the air flow, so that the air flow is not sufficiently sucked and is not absorbed. May open umbrella.

[0004]

The flying object according to the present invention is intended to solve the above-mentioned problems, and after being launched and flying by a rocket motor, the balloon is opened to softly land and hold the water. A flying object for propelling a body toward a target is characterized by a configuration including means for supplying gas into the balloon to forcibly open the umbrella.

[0005]

That is, in the flying object according to the present invention, after the flying object is launched by the rocket motor, the balloon is opened and the underwater vehicle holding the soft water is held toward the target. The gas is supplied into the balloon to force the umbrella to open, and the irregularity of the balloon is suppressed by the pressure of the gas supplied to the balloon in any airflow, and the balloon is reliably opened. To do.

1 and 2 are explanatory views of a flying body according to an embodiment of the present invention. In the figure, the flying body according to the present embodiment is used as an aerospace device, and when launching the flying body, the underwater vehicle 4 is housed in a capsule 3 of the flying body and folded into the capsule 3. Equipped with a balloon (Varuto) 1 and a rocket motor 5 at the rear of the capsule 3.
It is provided so that it can be removed. The underwater vehicle 4 is provided with a homing device, an underwater propulsion device, and the like, which are not shown. In this flying body, in order to prevent the balloon 1 from being opened, a gas generator 2 such as a gas cylinder or a gas generating agent is attached in the balloon 1 as shown in the figure, and the balloon 1 is discharged into the air flow. And gas is supplied into the balloon 1 to forcibly open the balloon 1.
The gas generating device 2 may be, for example, a device that ignites solid fuel, such as used when inflating an airbag of a car, by an ignition trigger to generate gas. There is no problem even with the gas generators used conventionally.

The flying object is launched from an aircraft or the ground and flies in the air at supersonic speed, and the rocket motor 5 is separated when the flying object approaches the target point to some extent. Immediately after this separation, the balloon 1 is released from the capsule 3, and gas is supplied into the balloon 1 by the gas generator 2 in the balloon 1 to expand the balloon 1. After the balloon 1 is expanded, the pressure of the gas is further increased to bring the balloon 1 into a stable open umbrella state, sufficiently decelerating to the subsonic state, and then softly immersing the capsule 3 in water. When the capsule 3 reaches the water, the underwater vehicle 4 separates from the capsule 1 and travels while being guided toward the target by the homing device.

In this way, the gas generator 2 is attached to the balloon 1.
The gas generator 2 supplies gas into the balloon 1 regardless of what kind of air flow the balloon 1 has when it is attached.
The rigidity of the balloon increases, and the balloon 1 deflates or swells when the umbrella is opened.
It is possible to prevent the deceleration force from being lost due to an irregular phenomenon such as). In addition, the balloon 1 can be surely opened to decelerate regardless of the airflow. Since the impact of the flying body upon landing is mitigated in this way, the structure and functions of the underwater vehicle 4 are not impaired, and the flying body is launched to a certain extent after flying over a long distance. It is possible to land near the target and run the underwater vehicle 4 from underwater toward the target.

3 and 4 are explanatory views of a flying body according to another embodiment of the present invention. In the figure, the structure of the flying body according to the present embodiment is almost the same as that of the flying body according to the above embodiment, but the gas generator 2 is provided not on the inside of the balloon 1 but on the capsule 3 side, The gas generated in the device 2 is sent into the balloon 1 through the gas inlet pipe 7. Further, this flying body is also operated in the same manner as the flying body according to the above-mentioned embodiment, but when the balloon 1 is opened to a predetermined elongation, the gas inlet pipe 7 is automatically detached, and the balloon 1 is At the time of stable opening, the gas generator 2 is also separated and comes off. Even in this flying body, the rigidity of the balloon 1 is increased by the pressure of the gas, irregular phenomena such as breathing of the balloon 1 can be suppressed, and even the capsule 3 having a supersonic speed can be easily decelerated. The same action and effect as those of the flying object can be obtained. When the underwater vehicle 4 is not stored in the capsule 3 in the flying objects according to the above two embodiments, the balloon 1, the rocket motor 5 are directly attached to the underwater vehicle 4.
The gas generator 2 can be used by substituting the underwater vehicle 4 with the capsule 3 as it is, for example, by mounting.

[0010]

The flying body according to the present invention is constructed as described above, and since the balloon can be surely opened in any air flow, the impact of the underwater vehicle during landing is mitigated. The structure and functions of the underwater vehicle will not be impaired, and it will be possible to sail safely toward the target.
