Abstract: A rocket glider stabilization system wherein a releasable, granular, counterweight, or ballast material is provided in the forward end of a model rocket aircraft to offset the weight of a tail mounted rocket motor assembly. The counterweight ballast material is releasably maintained in a counterweight bay formed at the opposite end of the model glider fuselage from the rocket motor. A rocket body tube connects the rocket motor with the counterweight bay and, when the ejection charge of the rocket motor is ignited, the ejection charge pressure ruptures or opens a retaining structure to release the ballast and maintain the desired center of gravity for glide flight of the rocket back to the ground. At least one adjustable or fixed trim tab is employed on at least one of the flight surfaces to induce the desired glide path return for the model aircraft.

Abstract: A practice rocket for antitank weapons comprising a head and a support rod fastened to the head, the support rod carrying a tracer charge at its rearward end, and a propulsive charge in the form of gunpowder rods distributed around the support rod. The gunpowder rods are fastened to the head or to a disc attached to the head, and the support rod and the gunpowder rods are surrounded by a sleeve having a cylindrical portion and a narrow portion constituting a nozzle. The tracer charge is situated in front of the nozzle, and is ignited simultaneously with the firing of the rocket.

Abstract: An inflatable dummy target comprising a chassis of inflatable ducts wrapped with a sheet. The chassis of inflatable ducts can include one or more ring shaped ducts and one or more elongate ducts. The chassis can include at least two ring shaped ducts interconnected by one or more elongate ducts. The dummy target can include several attached axi-symmetrical sections, each section have a chassis of inflatable ducts. Each section can be conical, frustoconical or cylindrical, thereby achieving a concave or convex dummy target geometry.
