Studying the Dynamic Properties of an Amplifier Board Execution Block in Terms of False Tripping of an Aircraft Fire Suppression System

Abstract

The paper presents selected results of studies at the Polish Air Force Institute of Technology in the field of false activation of execution blocks used in SSP-FK aircraft fire suppression systems. An SSP-FK fire suppression system (as one of the main onboard protection systems) used on many types of military aircraft operated in the Polish Armed Forces. The results of statistical analyzes regarding the type of disability, their symptoms and causes determined by the engineering-air staff operate aircrafts with SSP-FK fire suppression systems. There are presented research hypotheses describing possible causes of false activation of execution blocks (Not causing permanent damage in SSP-FK fire suppression systems). With the purpose of determining the conditions of false fire alarm, simulation models of SSP-FK fire suppression system execution blocks were developed. The simulation model study was conducted in Circuit-Maker computing packages. The results of these works were used to diagnose selected modules and blocks of the SSP-FK system during the study of actual cases of their false tripping.
