MRLS ROCKET PROJECTILES STABILIZING METHODS (RETROSPECTIVE; OBJECTIVE AND SUBJECTIVE FACTORS THAT INFLUENCED THE METHOD OF MRLS ROCKET PROJECTILES STABILIZING). PART 2 (To the 60th anniversary of the adoption of the Grad MRLS)

Abstract: The article is devoted to three periods of development of indigenous multiple rocket launcher systems (MRLS), in which aerodynamic (M-13 projectiles), turbojet (M-14-OF projectiles) and again aerodynamic (9M22 projectiles) MRLS rocket projectiles (RPs) stabilizing methods were successively used on the trajectory. An important subsystem of the MRLS is the RPs launch subsystem — launch vehicle (LV), the requirements for which (in the history of the creation of the MRLS «Grad») directly affect the design of the stabilization units of the MRLS destruction subsystem — RPs. The stabilizing method is also determined by the required firing range and measures of dispersion. Sometimes it can be prescriptively specified for the use of already proven design schemes. And, of course, the competence of the parent company-developer leaves an imprint on the design of the projectile, the change of which can radically change the appearance of the sample.
