Abstract

Armament systems such as guns, launchers simulators are effective tools for training armed forces personnel. A firearm is a complex biomechanical system, so the best quality of training is achieved when training in a simulator, repeating the dynamic processes of the weapon by simulating the perception of real weapon use (feeling). The paper investigates the dynamic and stability properties of the short-range air defense system RBS-70. The RBS-70 short-range air defense system is designed to combat low-flying air targets. The purpose of this paper is to present the physical and mathematical models with com numerical dynamic simulation of the launcher in the first phase of missile flight. The theoretical model was formulated in the vertical plane and verified by the numerical modeling simulation.

Highlights

  • A short-range air defense system is an effective tool for the state defense against low flying air targets such as helicopters or air attack aircraft

  • Most of the short-range air defense systems consist of a stand, a launcher and a missile

  • The first stage missile launches from the short-range air defense system RBS-70 was modeled

Summary

Introduction

A short-range air defense system is an effective tool for the state defense against low flying air targets such as helicopters or air attack aircraft. Most of the short-range air defense systems consist of a stand, a launcher and a missile. In developing field training equipment for short-range air defense systems, it is very important to evaluate missile launch dynamic processes and to give the system operator the real shooting feelings. The first stage missile launches from the short-range air defense system RBS-70 was modeled. The system consists of a stand 3, a sight 2, and a container with a missile 1. The zoom unit, which is a part of the Optics Unit, has the function to find the missile upon launching and subsequently zoom onto the target This beam is reflected by a Stabilized Mirror Unit and transmitted through the front sight window. The stand is built on the ground using legs, which has two common deformable elements with stiffness k11, k12, and damping c11, c12 [8]
