Description

a miniature rocket

technical field

The utility model relates to the technical field of rockets, in particular to a miniature rocket.

Background technique

In recent years, micro-rotor UAVs are being received by the military, armed police and public security special operations due to their small size, low cost, low requirements for take-off and landing sites, easy to carry and use, and the ability to take off and land vertically and hover. More and more attention is paid to the troops, and it has been widely used to perform lightweight tasks such as aerial reconnaissance and on-site surveillance. Among them, micro-rotor drones are equipped with integrated weapon stations to use micro-rotor drones in low-altitude complex environments. Carrying out air-to-ground reconnaissance and strike missions is one of the key directions of development.

Due to the weak impact resistance of micro-rotor UAVs, the load capacity is very limited (usually not more than 5kg). However, traditional lethal and non-lethal munitions have large launch overload, short range, high quality, large volume, single damage mode, high cost of precision-guided munitions, and difficulty in miniaturization, so they are not suitable for micro-UAV-borne platform weapon stations. Design a small size, light weight, small micro-munitions that impact the platform when fired to meet the needs.

Utility model content

The purpose of the utility model is to solve the disadvantages of large size, large weight and large impact on the platform when launching in the prior art, and proposes a miniature rocket.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A miniature rocket is designed, including tail cover, tail, rocket engine, warhead, and fuze cabin. It is fixedly installed at the bottom end of the warhead along the axial direction of the projectile body, and the tail is fixedly installed on the rear casing of the rocket engine. set up.

Preferably, the empennage includes a connecting shaft, a curved wing, and a torsion spring, and the four sections of the curved wings are evenly arranged on the rocket engine casing in an X-shape, and each of the curved wings is provided with a connecting shaft at the root of the blade, The curling wings can be rotatably mounted on the connecting shaft, and each segment of the curling wings is fixedly mounted on the fixing ring of the rocket motor casing by means of a hole-shaft connection, and each connecting shaft is provided with a Torsion spring in compression.

Preferably, the warhead may be a warhead of various types, such as armor-piercing, blast-killing, detonation, tear gas, and smoke.

The miniature rocket proposed by the utility model has the beneficial effects that the whole bomb adopts a modular design and can be quickly installed without tools. The rocket is small in size, light in weight, and has a small impact on the platform when it is launched.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-3, a miniature rocket includes a tail cover 81, a tail fin 82, a rocket engine 83, a warhead 84, and a fuze chamber 85, and adopts modular design of each component, so that the utility model can replace each component according to the needs of use components to achieve different strike effects; when a component fails, components of other rockets can be used for direct replacement, and in the subsequent improvement and upgrade process, individual components can be upgraded, which is more flexible and can be improved. A variety of models are derived to meet different combat needs. The warhead 84 can be various types of warheads, such as armor-piercing, blast-killing, detonation, tear-gassing, and smoking, so as to adapt to different combat needs.

The fuze compartment 85 is fixedly installed on the top of the warhead 84 by screws along the projectile axis, the rocket motor 83 is fixedly installed on the bottom end of the warhead 84 by screws along the projectile axis, and the tail fin 82 is fixedly installed on the rear casing of the rocket engine 83. The screw fixation makes the disassembly and installation of the entire rocket more convenient and fast. In the face of different combat needs, different types of warheads can be replaced more quickly, thus greatly improving the combat efficiency. The tail fin 82 includes a connecting shaft 86, a curling wing 87, and a torsion spring 88. The four-section curling wing 87 is evenly arranged on the rocket engine 83 casing in an X-shape, and each curling wing 87 is provided with a connecting shaft 86 at the root of the blade. The curling wings 87 can be rotatably mounted on the connecting shaft 86, and each segment of the curling wings 87 is fixedly mounted on the fixing ring of the rocket motor 83 casing by means of a hole-shaft connection, and each connecting shaft 86 is provided with a compressed The state of the torsion spring 88, the torsion spring 88 is a special torsion spring, which can provide the torque of rotation and movement along the axis. A tail cover 81 is fixedly installed at the tail of the rocket engine 83 , and the tail fin 82 is received by the tail cover 81 and is arranged in close contact with the casing of the rocket engine 83 .

Before the rocket is launched, all the curved wings 87 are close to the casing of the rocket engine 83, the torsion spring 88 is compressed, and the outer cover 81 is used to accommodate the curved wings 87 to prevent it from unfolding. After the rocket is launched, the jet of the rocket engine 83 pushes open the tail cover 81 and releases the curling wing 87. The curling wing 87 is unfolded under the action of the torsion spring 88 to reach the maximum wingspan position. At this time, the torsion spring 88 pushes it away. into the card slot.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
