JPH04108199U - Protective cover device for infrared dome of flying body - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a protective cover device that is easy to handle and does not damage the dome when removed from the infrared dome. [Structure] A protective cover 2 formed into a bag shape from an elastic sheet material is disposed on the outside of the infrared dome 1, and when the projectile flies, gas is supplied from a gas supply device between the sheet materials. By inflating the protective cover 2 and making it removable from the infrared dome 1 by wind pressure, it is possible to prevent the infrared dome 1 from being damaged by raindrops at all times.
To realize a device capable of quickly removing a protective cover 2 without damaging an infrared dome 1 when a flying object flies.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention protects the infrared dome for a flying object from raindrops, and also protects it during flight. This invention relates to a protective cover device for an infrared dome on a flying object that is easy to remove.

0002

[Conventional technology]

The conventional protective cover is a protective cover 10 made of tempered glass as shown in FIG. , usually covers the front of the infrared dome 1, and activates the gunpowder when the projectile is launched. The protective cover 10 was destroyed and scattered by the evaluator 11.

0003

[Problem that the idea aims to solve]

Conventional equipment has a protective cover made of tempered glass, so care must be taken when handling it. In addition, there is a risk of damaging the infrared dome when detaching, making it even more expensive. Met.

0004 The present invention attempts to solve the above problems.

[0005]

[Means to solve the problem]

The protective cover device for an infrared dome of a spacecraft according to the present invention is a protective cover device for an infrared dome of a spacecraft. A resilient sheet material is placed on the outside of the dome and fixed to the fuselage using a mounting bracket. A protective cover formed into a bag shape, and two protective covers connected to the same protective cover. It is characterized by being equipped with a gas supply device that supplies gas between the sheet materials.

[0006]

[Effect]

In the above, a protective cover usually covers the infrared dome and protects it from raindrops. When the projectile flies, the gas supply device supplies gas between the two sheets of material. to inflate the protective cover, and the expanded protective cover will fall off from the mounting bracket due to wind pressure. , removed from the infrared dome.

[0007] As a result of the above, the protective cover is always attached to protect the infrared dome from damage caused by raindrops. It can prevent damage to the infrared dome when a projectile flies off. To realize a device capable of quickly removing a protective cover without any trouble.

[0008]

【Example】

A first embodiment of the present invention will be described with reference to FIGS. 1(a), 1(b) and 2. Figure 1 (a ), (b) and the present embodiment shown in FIG. It is arranged on the side, and one end is connected to the fuselage by a fitting 4, and two pieces of soft rubber are put together to form a bag shape. The protective cover 2, the gas generator 3 installed in the center of the protective cover 2, and and an ignition signal cable 5 connected to the gas generator 3 and routed from inside the aircraft. It is growing.

[0009] In the above, the protective cover 2 has a bag-like airtight structure, and the central part is For example, a gas generator 3 that generates a gas such as sodium azide is provided. The gas generator 3 is activated by the signal transmitted from inside the aircraft via the fire signal cable 5. When the protective cover 2 is moved, the protective cover 2 instantly inflates as shown in Figure 1(b), and the fixture 4 is released. It shifts, separates from infrared dome 1, becomes a balloon, and is blown away by wind pressure. .

0010 As a result of the above, the protective cover is always attached to protect the infrared dome from damage caused by raindrops. It can prevent damage to the infrared dome when a projectile flies off. To realize a protective cover device in which the protective cover can be quickly removed without any problems.

[0011] A second embodiment of the present invention will be described with reference to FIGS. 3(a) and 3(b). Figure 3(a),(b) ) In this example, two sheets of soft rubber are put together to form a bag, similar to the first example above. Protective cover 2 is used, but when the aircraft takes off, gas is instantly supplied from inside the aircraft. Gas is supplied between the two soft rubber sheets of the protective cover 2 through the supply pipe 6 to close the protective cover. This is to inflate the bar 2, and the action and effect are the same as in the first embodiment.

0012

[Effect of the idea]

The protective cover device for an infrared dome of a flying object of the present invention is a resilient seal. A protective cover formed into a bag shape from wood is placed outside the infrared dome to protect the When flying, gas is supplied from the gas supply device between the sheet materials to cover the protective cover. By inflating it and making it possible to remove it from the infrared dome by wind pressure, it is always red. It can prevent damage to the outside line dome from raindrops, and when a projectile is flying, Protective cover that can be quickly removed without damaging the infrared dome Realize the device.
