- Abstract
The problem of launch complexes (LC) fire safety fills a special place among the other tasks of ensuring launch vehicles (LV) launches due to the following: - concentration of considerable amounts of fire hazardous and explosive, corrosive, and toxic propellant components (PC) on limited areas; - application of the technological processes with high levels of energy concentration in local space; - high concentration of costly (often unique) equipment. An occurrence of fire at LC accompanied by PC spillage may lead to considerable economic, ecological, and social damage connected with emission of hundreds of tons of combustion products into atmosphere, their transfer to considerable distances, penetration into soil, subsoil waters, rivers, lakes, etc. The existing LC fire safety systems (FSS) based on the use of fire-hose barrel systems of fire-extinguishing liquid (FEL) supply with compact jets are obsolescent and require improvement, and the principles laid as a foundation of their functioning do not ensure the required effectiveness of fire extinguishing. The above factors and the increase in LV launches quantity as a whole cause an extremely high potential fire danger at LV LC which occurrence is fraught with the possibility of its quick growth till catastrophic extent accompanied by not only considerable material losses but also by extremely negative consequences for environment and personnel. The above mentioned causes the necessity of radical increase in LV LC FSS effectiveness, both from the viewpoint of fire extinguishing at fire initial phase and in the context of reliable heat protection of payload, LV and LC structures from the action of fire and ascending flows of PC combustion products. The paper presents the results of theoretical and experimental investigations, the data on the developments protected by the patents of Ukraine and Russian Federation, which created real prerequisites for updating of standard FSS allowing with minimal technological modifications to realize the hydroimpulsive method of FEL transformation into a volumetric-surface fire-extinguishing agent, which ensures: - generation of long flows of dispersed FEL with increased coverage areas; - reduction (5-7 times) of FEL consumption for fire extinguishing;
