Antitank rocket null for alert warning shooting

摘要

PURPOSE:To enable an alarm intention to be sufficiently transmitted to an aircraft of another nation showing invasion by a method wherein a rocket is provided with rocket propellant containing terminal hydroxyl group polybutadiene and ammonium perchlorate as its major constituent and having aluminum-magnecium powder. CONSTITUTION:An alarm firing rocket has as its major constituent terminal hydroxyl polybutadiene acting as binder and fuel and ammonium perchlorate acting as oxidant and further it has a rocket propellant containing aluminum-magnesium powder for metallic combustion. Discharging smoke discharged under combustion of the rocket propellant generates white smoke due to a contact with moisture in the air because ammonium perchlorate generates hydrochloric acid gas. In addition, solid materials such as black carbon and white aluminum oxide are contained in the discharged gas, so that a large amount of discharged smoke of dark grey is generated. It is reacted with oxygen in the air due to a mixing composition with rich fuel so as to generate a secondary firing, so that it has a superior visibility without being influenced by weather or daytime or nighttime. Thus, this device enables sufficiently a place alarming action to be given to an aircraft of another nation having invaded the teritorial space.
