Rocket projectile with pivoted extending guide fins - has gas pressure actuated guide fins extended after launching

摘要

The projectile, esp. a rocket, has pivoted guide fins in the combustion chamber region. These fins are extended about the axis at right angles to the projectile longitudinal axis and held on the projectile casing. Each fin has axial actuator operated by the propellant gas pressure. This rocket is relatively simple to make and the overall rocket length is based on economy of materials used. The combustion chamber closing cover is ejected by pressure after launching of the rocket. The cover is connected with the actuator and the cover has extensions brought into contact with the projections on each fin. The fins are thus extended after launching.
