A Screening Method to Evaluate the Performance of Decoy Flares

摘要

The MTV-flares are produced for use in aircraft countermeasures system to combat heat seeking missiles. The aim of this work was to develop a testing system that could be used to evaluate the performance of various flares. Therefore such testing methods were selected which will give information on both the functioning and the IR-response of flares. The study was carried out at Defence Forces Technical Research Centre (PVTT) with different MTV flares. The measurements which were used to evaluate the functioning were the burning time, the ejection speed and the burning temperature. The measurements were done with a thermal camera and video recording. Radiometric measurements were conducted on MTV flares to determine the IR-response of flares. All measurements were done as static and dynamic testing. In the static testing the flares were burned on a specially built steel holder 1.7 meter above the ground. In the static testing the flares were ignited by electric igniters. In the dynamic testing the flares are loaded in a magazine and installed into a dispenser mounted on a specially built support. The flares were fired from the dispenser by ignition the impulse cartridge.
