    Abstract: The invention deals with a method of eliminating the base resistance of a flying object. Included in the invention is a device specially adapted to the method. According to the invention base resistance is eliminated by means of the combustion gases from a combustion chamber (2) built into the object being released from the said chamber and led towards the base surface of the object via devices (9-16, 20, 24 and 30) which eliminate the greater part of the gases' motive energy before or simultaneously with their reaching an outlet located on the base surface of the object through which they are allowed to flow out under such conditions that the base resistance of the object (1, 26) is at least partly eliminated.

    Abstract: The invention relates to means for reducing the spread of shots in a weapon system in which the shots are fired from the weapon in a ballistic trajectory from a launching device towards a target. It comprises means for measuring the position of the target, means for measuring the muzzle velocity of the ammunition unit, and, in one embodiment, also means for measuring the actual trajectory parameters of the ammunition unit (shell, projectile or the like), for instance the reduction of velocity in a specific trajectory distance. In response to these values the impact point is predicted. A braking command is transmitted to the ammunition unit via a radio line in response to the difference between the actual position of the target and the predicted impact point for braking the velocity of the ammunition unit in order to improve the hit probability. The braking means preferably comprises a plurality of braking flaps distributed about the periphery of the ammunition unit. Normally the braking flaps are retracted but they can be activated into a protruding position by an actuating device. Alternatively the desired braking effect can be obtained by separating different parts of the nose section from the body of the ammunition unit in order to increase its air-resistance.

    Abstract: A supporting cupola is provided for the propellant of a base-bleed gas generator for a projectile, shell or the like. The supporting cupola is arranged in the discharge aperture of the gas generator and provides a reduced gas outlet area from the base-bleed combustion chamber during launch of the projectile. The supporting cupola is made of a material which is easily eroded by the hot combustion gases, such as magnesium. The reduced outlet area increases the pressure in the combustion chamber during the acceleration stage of the projectile so that an improved ignition of the propellant and reduced risk of extinguishment is obtained. Due to erosion of the cupola material the outlet opening area increases with time providing a regressive burning rate of the propellant which means an increased base-bleed effect with respect to the firing range of the projectiles.

    Abstract: The invention relates to a training weapon system for a portable recoilless anti-armor weapon of the type which comprises a sub-caliber insert barrel (1) arranged in the bore of the launching barrel of the full-caliber weapon. In order to improve the accuracy of the system and make it more safe as well as less expensive when compared to previous systems of this type, the sub-caliber insert barrel (1) has a rifled bore to make the training projectile spin stabilized. The forward aligning member (5) for centering the insert barrel (1) is engaging the ridges of the rifles in the rifled portion of the barrel in the recoilless full caliber weapon. By such an arrangement it can be avoided that length tolerances give rise to undesired radical deviations which might result in a mis-alignment of the insert barrel (1) within the gun bore. This could happen with the forward aligning member engaging the conical, smooth-bored firing chamber in the barrel.

    Abstract: The subject invention concerns a general method of producing countermass weaponry and is based on the use of a high-pressure system and a low-pressure system with a countermass (12, 26, 26′, 38) acting against the low-pressure system. The high-pressure system (7, 23, 23′, 36) shall, in practice, be formed by the combustion chamber for the weapon propellant charges (8, 22, 22′, 35) while the main part of the low-pressure system (25, 25′) shall, in initial stages, be formed by the storage and acceleration chamber for the countermass. The advantage of the subject invention is that said invention offers a possibility of achieving lower pressure levels around the grunner without, for such an end, diminishing the range of the weapon (1, 13).
