Description

The invention relates to rocket and space technology, and in particular, to the design of rocket booster blocks that are part of space rockets intended for the removal from the reference orbit to the working energy orbits of various space objects-payloads.

Known rocket block according to the patent RU 2153447, B 64 G 1/40, 1/00, 1/16, containing a marching engine, an oxidizer tank with a frame and a fuel tank, an inter-tank farm, an oxidizer tank suspension truss, an upper adapter.

Known rocket block according to the patent RU 2165379, B 64 G 1/00, 1/16, 1/40, containing a marching engine, an oxidizer tank with a frame and a fuel tank, an inter-tank compartment, an interface farm with a launch vehicle, an oxidizer tank suspension truss, payload pairing farm.

For the prototype adopted rocket booster unit according to patent RU 2165379, 64 G 1/00, 1/16, 1/40.

The disadvantage of analogues and prototype is that the oxidizer tank is cantilevered in the block using the oxidizer tank suspension truss, as a result of which the structure of the oxidizer tank fastening is overweight.

The objective of the proposed missile block is to improve the mass characteristics of the block by improving the fastening of the oxidizer tank.

The problem is solved due to the fact that in the rocket booster block containing the marching engine, the oxidizer tank with the frame, the fuel tank, the inter-tank compartment, the interface farm with the payload, the interface farm with the booster rocket, the oxidizer tank is fixed in the block with its frame between the lower frame trusses with a payload and the upper frame of the inter-tank compartment, being thereby an integral part of the power range of structural elements of the block, which includes the truss of the interface with a launch vehicle, the frame of the fuel tank o, the inter-tank compartment, the oxidizer tank frame, the payload interface farm, as a result of which the mass of the block is reduced.

The drawing shows the proposed rocket upper stage, where:

1 - oxidizer tank;

2 - fuel tank;

3 - marching engine;

4 - inter-tank compartment;

5 - farm pairing with a payload;

6 - frame farm coupling with a payload;

7 - farm interface with a launch vehicle;

8 - frame of the inter-tank compartment;

9 - frame of the oxidizer tank;

10 - fuel tank frame.

A rocket booster block is proposed, comprising a cruising engine 3, an oxidizer tank 1, a fuel tank 2, an inter-tank compartment 4, a payload pairing farm 5, a booster pairing farm 7. An oxidizing tank 1 is mounted in the block with its frame 9 between the frame of the pairing farm with a payload of 6 and a frame of the inter-tank compartment 8, thereby being an integral part of the power series of structural elements of the unit, which includes the interface farm with the launch vehicle 7, the frame of the fuel tank 10, the inter-tank compartment 4, the frame of the oxide tank Ithel 9, conjugation farm payload 6.

For the case when the oxidizer 1 is used in the cryogenic tank unit 1, the payload interface farm 5 and the inter-tank compartment 4 can be made of materials of low thermal conductivity or between the frame of the oxidizer tank 9 and the frame of the interface farm with the payload 6, as well as between the frame of the oxidizer tank 9 and the frame inter-tank compartment 8 can be installed intermediate elements of thermally insulating material. This device operates as follows. External inertial loads arising both during operation of the unit and during its transportation are perceived by the power circuit, which includes the interface farm with the launch vehicle 7, the frame of the fuel tank 10, the inter-tank compartment 4, the frame of the oxidizer tank 9, the frame of the interface farm with the payload 6, while the forces from the oxidizer tank 1 are transferred directly to the joint of the inter-tank compartment 4 and the frame of the coupling farm with the payload 6.

This makes it possible, unlike the prototype, to exclude from the block design the power elements of the cantilever fixing of the oxidizer tank, which in turn allows to reduce the total mass of the rocket block by ~ 2%.
