Pyro-activation Reliability Enhanced Coolant Gas Supply System (DUALPI-GSS) for Missile Seeker Heads

Abstract

The product that is the subject of the Utility Model (FM) application relates to the gas cooling of seeker head detectors in guided missiles, which are cooled using thermodynamic cycling. The aim of this invention is to develop and introduce a new type of Pyro-GSS designed with pyrotechnic pin pushers / pullers for cooling missile seeker heads, according to the current state of the art, that will increase the probability (reliability) of opening the gas line to initiate the cooling process of the seeker head to activate the guidance system. This product offers an advantage over existing counterparts by using two (double) pin pushers / pullers instead of one, and it also meets the requirements in terms of the limited volumetric envelope criteria of the application area. The product (DUALPI-GSS) that is the subject of the Utility Model (FM) application will significantly reduce the probability of a missile flying blindly (guidance system failure) after being launched at the target, and will support the reduction of foreign dependence and the achievement of economic gains by enabling the use of domestically developed pin pusher / pull types in domestic missile systems.

Description

1 TARIFF PYRO-ACTIVATION RELIABILITY FOR MISSILE SEEKING HEADS HAS BEEN IMPROVED. REFRIGERANT GAS SUPPLY SYSTEM (DUALPI-GSS) 1. Technical Area 5 The product that is the subject of the Utility Model (FM) application (see Figure-1) is the thermodynamic cycle of guided missiles. It relates to the gas cooling of seeker head detectors that are cooled using gas cooling. 2. State of the Art In the known state of the art, there are 10 pyrotechnically activated Gas Supply Systems (Pyro-GSS). Cooling process; opening the refrigerant gas line using pyrotechnic devices (such as pin pushers / pullers). (blockage in the flow line due to the pressure effect created by an explosive activated by electric current) (breaking) initiates the process, and the possibility of opening (or not opening) the gas line is pinned. It is directly related to the reliability level of the propellant / attractor. That is to say, to the pyrotechnic device used. Even when an electric current is applied, the pin is unable to perform its push / pull movement and / or does not have sufficient 15 The gas flow line is not opened due to the absence of a pushing / pulling force. It is possible to experience this. In existing Pyro-GSS systems manufactured according to the known state of the art, the pin pusher / pull mechanism itself... minimizing the possibility of "the gas pipeline not being opened" which is limited by its own reliability to (or maximize the probability of opening) a pin pusher / pull with higher reliability 20 There is no other option besides using it. 3. Purpose of the Invention The purpose of the invention is to cool missile seeker heads, according to the current state of the art. Pyro-GSS systems, designed with pyrotechnic pin pushers / pullers, require 25 pins to engage the guidance system. the possibility of opening the gas line to initiate the cooling process of the seeker head (Pyro-GSS) The goal is to develop and introduce a new type of Pyro-GSS that will increase its reliability. The product that is the subject of the Utility Model (FM) application is (DUALPI-GSS); - Pyrotechnic devices such as existing pin pushers / pullers with a specified reliability level by the manufacturer. By enabling the multiple (dual) use of devices, it reduces the possibility of the gas line not being turned on, 30 2 The possibility of a missile flying blind (guidance system malfunctioning) after being launched at the target is serious. will reduce it to a certain extent, - The pin, which is undergoing domestic / national development studies to increase its reliability level. By enabling the use of pusher / puller types in domestic missile systems, it prevents exports abroad. This will help reduce dependence and generate economic benefits. 5 4.
