RU217019U1 - Top cover for transport and launch container - Google Patents

Abstract

The utility model relates to rocket technology. It is designed to protect the product located in the TPC from the adverse effects of weather and climatic factors, as well as to ensure the shock-free exit of the product from the TPC.

The device consists of a round foam plate of variable thickness, installed along the outer contour between the metal ring and the flange using a screw connection.

The destructible cover ensures the tightness of the TPK during its ground operation in the entire temperature range at altitudes, and also allows air transportation in an unpressurized cabin without additional steps for preparing the TPK. When using the product for its main purpose, the cover is organized by the toe into 12-15 separate parts in the form of sectors of a round foam plate, without preventing the free passage of the product from TPK. The dimensions and weight of the fragments of the cover are such that in their subsequent fall they do not cause any damage to the external elements of the BM structure.

Description

The utility model relates to rocket technology. Designed to protect the product located in the transport and launch container from the adverse effects of weather and climatic factors during its ground operation, incorrect calculation actions, as well as to ensure the shock-free exit of the product from the TPK when it is used for its main purpose.

The closest analogue in design, technical essence and result to the utility model is a destructible cover (patent No. 175301). The utility model relates to the field of defense technology and can be used to create samples of missile and torpedo weapons of surface ships of the Navy, for example, transport and launch containers (TLC) of missile and torpedo launchers.

The disadvantages of a similar destructible cover are:

- accumulation on the lid of precipitation (water, snow, ice, etc.);

- a high risk of mechanical impacts at the time of launch of the product, in the event that sectors of the destructible cover get into the structural elements of the superstructures of the launcher and the carrier.

The technical problem solved by the proposed utility model is to eliminate these problems.

The problem solved by the present utility model is to create a fairly easy-to-use, durable hermetic destructible cover of the transport-launch container, collapsing into sectors from the impact of the bow at the start of the product with minimizing the consequences of mechanical impact and impact-free exit of the product from the TPC.

The problem is solved, firstly, due to the fact that the outer side of the foam cover is flat, does not protrude beyond the dimensions of the metal ring, and ensures that precipitation (snow, water, ice, etc.) does not accumulate during ground operation on the BM.

Secondly, the shape of the inner surface of the newly developed foam cover is made in the form of a spherical recess in the central part, twelve radial grooves and an annular groove on the passage diameter of the cover are concentrators for separating the detachable cover disk into sectors from the impact of the bow at the start of the product. The small parts of the sectors of the destroyed new cover, in comparison with the cover according to patent 175301, minimizes the consequences of mechanical impacts, if they enter the structural elements of the superstructures of the PU and the carrier.

The device consists of a round foam plate of variable thickness, installed along the outer contour between the metal ring and the flange using a screw connection.

In FIG. 1 shows a drawing of the top cover, which consists of a non-metallic destructible cover 1 of a flat shape of variable thickness, installed between the metal ring 2 and the flange 3 using screws 4. The sealing of the joint of the cover 1 with the ring 2 and the flange 3 is carried out using a sealant 5. Due to different coefficients thermal expansion of metals and non-metals, between cover 1 and ring 2 with flange 3 there is a gap filled with sealant 5 to compensate for the difference in temperature deformations of the foam and metal and to eliminate internal stresses in the foam cover during operation of the TPK in the entire temperature range.

The device works as follows:

In the process of direct launch of the SAM, when the rocket exits the TPK, the cover 1 is destroyed under the influence of force from the forward part of the SAM. In this case, the control of the nature and zone of destruction of the cover 1 is carried out due to the geometric parameters of the annular groove, radial weakening (slots) and the central spherical recess.

Thus, the proposed top cover for the transport and launch container provides the ability to create a fairly easy-to-use, durable sealed destructible cover of the transport and launch container over the entire temperature range, which collapses by 12-15 sectors from the impact of the bow during the launch of the product while minimizing damage to external elements the design of superstructures of the PU and the carrier and the impactless exit of the product from the TPK.

Claims (1)

Destructible top cover of the transport and launch container, consisting of a foam plate of variable thickness, fixed in a cage, including a metal ring and a flange, characterized in that in the central part of the foam plate on the inner surface there is a weakening in thickness in the form of a spherical recess for placement in it the nose of the product with a minimum gap, from which weakening radial slots diverge, smoothly turning into an annular groove located concentrically to the diameter of the cover and corresponding to the diameter of the flow section of the launching rocket.
