; Disclosed on pages 177 to 178, published by the Institute of Space and Astronautical Science, SES Data Center, dated August 15, 1981.

〔problem〕

However, the conventional means described above has a problem in that a sufficient field of view cannot be provided to the observation equipment such as the lens 7.

This is because when a rocket launches, a large amount of smoke generated from the main booster 2 and sub-booster 5 is blown back from around the launcher, and in order to protect the observation equipment from contamination or emitted heat from this smoke, This is because the observation window must be made as small as possible, or the observation equipment must be retracted into the nose 4 as much as possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sufficient field of view to observation equipment while protecting it from blowback fire and smoke.

[Means of the present invention]

The means of the present invention that solves the above problems includes a cover body that protrudes outward from the rocket body and has an observation window, a cover plate that is removably attached to the cover body and covers the observation window, and that responds to an activation signal. and a signal transmitting means that transmits the activation signal after a predetermined time has elapsed from the time of firing.

[Effect]

According to the above means, when a predetermined time has elapsed from the time of launch, the cover plate is released by the actuation signal from the signal transmitting means, and the observation window is opened for the first time. By doing so, the inside of the cover body can be isolated from the fire and smoke. Therefore, the observation equipment can be placed inside this protruding cover body facing outside the rocket body, and it can also be placed close to the observation window, allowing the field of view of the observation equipment to be expanded.

2, an outer cover 24 in which a transparent window 23 with a larger diameter than the transparent window 21 is formed, and a filter 25 formed in a disk shape using glass or transparent resin, and backings 28, 27 on both sides of the filter 25. Apply the inch cover 22
and the outer cover 24, and are integrated by tightening the inch and outer cover 22.24 together using a plurality of bolt donuts 28 arranged around the filter. Also, when this cover plate 20 is viewed from the front as shown in Fig. 1, the lower edge ff of the inch cover 22 is
&22a and both side edges 22b, 22b are made to protrude beyond the lower edge and both side edges of the outer cover 24. Also using FIG. 3, 29.29 is the main booster 2.
A cover holder fixed to the inner cover is provided at a position corresponding to the front side edges 22b, 22b of the inner cover, and at a position where the front end of the holder contacts the end wall 15 of the cover body.

30 is a stepped portion formed by cutting out the front end of this cover holder. Then, both sides of the lower edge 22a of the inner cover are inserted into the stepped portions 30° 30, and one side edge 22b is fastened to the end wall 15 of the cover body using screws 31 made of aluminum or the like. It is.

Reference numeral 40 denotes a button which together with a kick spring 49, which will be described later, constitutes a release means for the cover plate 20. In this button, 41 is an adapter, which is located behind the one side edge 22b of the inner cover 22 and is screwed onto the end wall 15 of the cover body. 42 is a cylinder formed in the inner part of the adapter 41, 43 is a piston fitted into this cylinder, 44 is a bushing bin integrated with this piston, this bushing bin penetrates through the deep part of cylinder 42, and its tip is covered with an inch cover. 22 or close to it. A gunpowder cartridge 45 is located behind the piston 43 and is screwed onto the adapter 41, and contains gunpowder as a rapid gas generating agent and a detonator such as an impact sensing type.

46. 46 is the side edge 22b on both sides of the inch cover 22,
The spring holders 22b are fastened using screws 47, and each spring holder is provided with a spring housing 48 opening opposite to the cover holder 29, and the kick spring 49 is elastically loaded in this spring housing.

Reference numeral 50 denotes an activation signal transmitting means, which is constituted by, for example, a known time delay means constructed using a time delay tube filled with a time delay charge and a point explosive. 51 is a connector for signal branching (rocket)
When a firing signal, for example, a detonation wave signal, is emitted, this signal is sent to the igniter of the rocket via a connector 51 and a detonating wire 52, and at the same time is sent to the time delay means 50 via a detonating wire 53. The above-mentioned delay medicine is ignited. When a predetermined time set in the time delay tube has elapsed, an activation signal (detonation wave signal) S is emitted from the time delay means 50, and this signal S is transmitted to the detonator of the gunpowder cartridge 45 by the detonating wire 54. .

The configuration of the embodiment is as described above, and when the rocket leaves the fire and smoke blowback area after a predetermined delay time has elapsed after launch, the activation signal S is emitted from the delay means 5o, and this signal S The detonator of the gunpowder cartridge 45 is fired to detonate the gunpowder, and the high pressure of the combustion gas acts behind the piston 43. Therefore, as a result of this piston and the bushing pin 44 strongly pressing the inch cover 22, the screw 3 made of aluminum etc.
