Embodiment 1

[0044] Embodiment one, combining Figure 1-Figure 5 Describe this embodiment mode, the ship passive jamming rocket fixed launching deflector of the present invention is a kind of safety design designed to solve the destructive influence of the gas flow discharged by the engine on the ship itself and nearby equipment when the rocket is launched. The protective device is especially suitable for small and medium-sized ships with compact deck layout and light ships with aluminum alloy hull structure. The deflector of the present application can not only guide the jet stream of the jet tube of the launching device smoothly into the atmospheric environment, but also control the influence range of the lateral diffusion of the jet stream, and at the same time, it will not affect the launching device and surrounding ship equipment during application In normal use, its shape and size are also integrated into the overall design of the ship.

[0045] Specifically, the ship's passive jamm...

Embodiment 2

[0063] Embodiment 2. The difference between this embodiment and Embodiment 1 is that a plurality of evenly distributed lightening holes 6 are opened on the support plate 2, and the lightening holes 6 opened will not affect the structural bearing capacity of the deflector. , and can reduce its weight, so that its shape, weight, and size can be integrated into the overall design of the ship, so as to meet the design requirements of the overall weight and carrying capacity of the ship. .

Embodiment 3

[0064] Embodiment 3. The difference between this embodiment and Embodiment 1 or 2 is that the deflector needs to be fixed on the deck of the ship during use. Since the deflector is made of steel, the hull structure is Aluminum material, therefore, in the process of using the deflector, the transition connection between the steel deflector and the aluminum hull structure should be considered, therefore, a transition joint is set between the deflector and the ship deck 1 . The transition joint 1 is composed of an aluminum plate and a steel plate, and the aluminum plate and the steel plate are fixed by gluing. The aluminum panel of the transition joint 1 is fixed to the hull structure, and the steel panel is fixed to the bottom plate of the deflector. In order not to affect the normal use of the launching device, and at the same time not affect the normal work of loading and unloading rockets, preparations for weapon firing, equipment inspection and maintenance, etc., during use...

Abstract

The invention discloses a naval ship passive jamming rocket projectile fixed launch flow guide device and a design method of the naval ship passive jamming rocket projectile fixed launch flow guide device. The design method of the flow guide device specifically includes the following steps that launch parameters of a launcher are obtained; according to the launch parameters of the launcher, the tail flame jetting range of the launcher is obtained in a simulation mode; according to the tail flame jetting range of the launcher, the size of a flow guide face of the flow guide device is determined; the flow guide angle of the flow guide face of the flow guide device is determined; and side flow faces are set, a flow guide device model is established according to the size of the flow guide face, the flow guide angle of the flow guide face and the inclination angle of each side flow face, and the structure of the flow guide device is optimized and adjusted. The flow guide device can smoothlyguide jet flows of jetting pipes of the launcher to the atmosphere environment, the lateral diffusion influence range of the jet flows can be controlled, and the problem that a hull structure and ship face equipment around the hull structure are damaged due to repeated scouring of the jet flows is effectively solved.

Description

technical field [0001] The invention relates to the technical field of missile launch, in particular to a fixed launch deflector for ship passive jamming rockets and a design method thereof. Background technique [0002] Missiles, rockets and other weapon launching devices are usually installed on the deck of a ship. Due to the limitations of ship surface materials and space, the high-temperature and high-speed gas jets generated by the thermal launch tail engines of missiles and rockets will directly affect the hull structure and its surroundings. The installation and equipment of the ship will have serious impact and thermal ablation on the hull structure and the surrounding installation and equipment. [0003] In the design of small and medium-sized ships, due to the constraints of the ship's environmental conditions, passive jamming devices are usually arranged in the ship's surface area with a more complex environment, and the nearby hull structures are all made of alum...
