UA28238U - Tactical missile warhead "kayak" - Google Patents

Abstract

The invention relates to weapon technique. A tactical missile warhead "kayak" comprises a body compartment and control compartment with fins. In order to increase the range capability the body compartment or body and nose compartments are sectional with movable sections, each of said sections is pivotable relative to the bottom of the body compartment.

Description

Description of the invention

The useful model belongs to weapons, in particular, but not exclusively, to projectiles and rockets, which are characterized by 2 main parts.

The modern level in this field of technology is characterized by a variety of main parts that ensure the best placement and delivery of the target payload of missiles and projectiles. For the most part, the main parts (GU) of existing rockets and projectiles have the form of a purely symmetrical and unchanged combination of cylindrical and conical shells, decorated with stabilizers or pylons (1.21. 70 In such conditions, increasing the efficiency of the main part follows the path of applying solutions to increase the density of the layout of the main part |C), use of systems for improving aerodynamic projectiles |4), creation of directional impression systems (5).

However, the proliferation of guided weapons has negated almost all the benefits of the unchanged symmetrical shape of the main parts, because modern flight control systems and methods allow you to control an object of any shape. In view of this, such aspects of ensuring efficiency as the furthest flight of the main part under the conditions of correct (controlled) orientation of the main part in flight come first.

The closest to the proposed technical solution is the composition of the projectile described in (b), which was chosen as a prototype.

The patent Ib) presents the main (front) part of the guided projectile, which includes the body and nose compartments and steering devices, which are connected while maintaining symmetry with respect to the longitudinal axis.

The basis of the useful model is the task of improving the design of the main part of the projectile in such a way as to increase its efficiency in general, first of all, the flight range, due to a different shape and mutual arrangement of elements, where the body and nose compartments with rudders can be made detachable on movable sections with the ability to rotate each movable section relative to the bottom diameter of the housing compartment.

The task is solved in such a way that in the proposed design of the main part of the "kayak" in the tactical projectile, the hull or hull and bow compartments with rudders are made removable on movable sections with the ability to rotate each movable section relative to the bottom diameter of the hull compartment.

To explain the proposed design, drawings and its description are attached.

The drawings show: so in Fig. 1 - General view of the "kayak" HG as part of the projectile; so on Fig. 2 - General view of the "kayak" HG in the variant with detachable hull and bow compartments in independent flight; c in Fig. 3 - General view of the "kayak" HG in the version with a detachable body compartment in independent flight. with

In the initial position (Fig. 1), the body 1 and nose 2 compartments of the main part are connected along the plane

From the section, forming a symmetrical geometric body of rotation, which contributes to the best overcoming of dense layers of the atmosphere in the composition of the projectile. Rudders 3 are located on the surface of the nose compartment.

In independent flight (Fig. 2), sections 11 and 12 of the body compartment are turned at a certain angle relative to the bottom diameter of the body compartment. The figure shows the rotation of the sections by 180 degrees. "

This configuration provides a double benefit for increasing the flight range: the minimum amount of frontal Z 70 resistance at the same time as the maximum amount of lift. c This is explained by the fact that

"Iz" - the ballistic coefficient of the "kayak" main part is improved by two times only due to a two-fold reduction in the cross-section of the main part, - the aerodynamic resistance drops significantly due to the improved body shape, which theoretically has no profile resistance. o Aerodynamic quality of such a body in comparison with a straight circular cone of the same height and diameter

Ge | increases several times and the flight range of the main part increases to the same extent.

Given the complexity of dividing the control compartment into parts, the shape of the main part "kayak" can be formed by cutting only the body compartment (Fig. 3). со 20 This design allows you to minimize aerodynamic resistance and other factors that lead to loss of flight range in the active part of the flight and provides a significant increase in the flight range of the main part. co Sources of information 1.
