摘要： A fin-stabilised projectile (1) forming a weapon for attacking a tank (2) from above wherein at the final phase of the flight to the target a force acting on the tip of the projectile causes descent. Due to a rotation of a control unit (4) which carries a target-detecting sensor a gyroscopic precession causes the projectile to oscillate and to be deflected from the required path. To overcome the yawing angle and lateral deviation caused means are provided in the projectile between control unit (4) and warhead body (3) for imparting to the body (3) a rotary impulse equal to that of the control unit (4) but in the opposite direction. The means is so constructed to be suitable also as driving means for the rotation of the control unit (4). The opposite rotation of the two parts of the projectile may be effected by combined jet-nozzles (7) and turbine means (9) (Fig. 3) or, by oppositely directed nozzles (10) and (11), Figs 5 and 6, on the respective parts, or, by a spiral spring (12), Fig. 8, mounted between the oppositely rotating parts, or, by screw-threaded means 5.9 Fig. 9.

摘要： A fin stabilized projectile for combatting a tank from above of the type including a rotating control unit disposed at the front of the projectile and containing a sensor for scanning the area to detect a target, and wherein the final phase of flying into the target is initiated by a force which acts on the tip of the projectile, particularly on the control unit. Since the control unit rotates relative to the warhead of the projectile to enable its sensor to detect the target, the gyro effect of this rotary movement generates pendulum movements in the projectile and thus causes deviations from the target at different target distances. To avoid yaw angles and lateral displacements of the projectile during the rotating-descending phase, a drive arrangement is provided within the projectile between the control unit and the warhead to impart an angular momentum to the warhead corresponding to the angular momentum of the control unit but directed in the opposite direction. Preferably this drive arrangement simultaneously serves as the drive for producing the rotation of the control unit.

摘要： The invention relates to a caseless cartridge having a projectile which is in the form of a disc and has an eccentrically mounted centre of gravity. During loading, the centre of gravity is always directed upwards, as a result of a groove which is provided in the cartridge. During firing, this results in the projectile rotating from bottom to top, or in the anticlockwise direction, about its own axis. In this way, a straight flight path is achieved at short ranges, and a highly curved flight path (boomerang effect) in the event of a steep firing angle.

摘要： A projectile, includes a head having a forward tip and a rear end, a stem extending from the rear end of the head and formed integrally with the head, and a sleeve positioned adjacent to the head and being collinear with the head and coaxial with the stem. The sleeve is hollow and substantially cylindrical and has an inner diameter and an outer diameter. A base is formed integrally with the stem by pressing a rearward end of the stem and expanding a rear dimension of the stem to capture the sleeve between the base and the head. The head and the base are rotatably dependent upon each other by connection with the stem, and the head, stem, and base are rotationally independent of the sleeve.

摘要： Launching an aeronautical system can comprise applying force or energy to the system in connection with accelerating the system. Responsive to the force or energy, an element of the system can move along a defined path within the system. The system can comprise a drive that converts motion along the defined path into rotational motion. The drive can rotate a mass within the system, which can be supported by a gas bearing. The rotating mass can comprise the moving element, a different system element, or the entire system. The rotating mass can produce angular momentum and can support gyroscopic stabilization of the aeronautical system. Rotational energy can be selectively imparted to and transferred between system elements in connection with stabilization management. System elements can moderate the system's response to impulsive stimuli associated with rotation and acceleration. A gas bearing can support an external surface of the system during launch.

摘要： Apparatuses for a projectile are provided, the projectile configured for weapons band launching, examples of the apparatus comprising a body, an inflation system and external walls. The body is inflatable by the inflation system, from a deflated configuration having a first volume to an inflated configuration having a second volume, greater than the first volume. The external walls are deployable from an undeployed configuration to a deployed configuration responsive to the body being inflated. In the undeployed configuration and at an operating airspeed, the center of pressure is located at a first position with respect to the projectile. In the deployed configuration the external walls provide a deployed external surface geometry exposed to an airflow corresponding to the operating airspeed, such that the center of pressure is located at a second position with respect to the projectile, different from the first position.

摘要： The present disclosure provides a projectile with a self-contained internal chamber. Reaction of propellant inside the internal chamber can generate high pressure and the resultant exhaust gases can be used for projectile linear acceleration, rotational acceleration or other purposes. Torque can be produced by exhausting the pressure via radially placed, tangential nozzles or other outlets and can be configured to induce sufficient projectile spin to stabilize the projectile without the need for barrel rifling. The internal chamber may be separate or integral to the projectile itself. The projectile may include two or more chambers or compartments internal to the chambers. The disclosed projectile allows for higher pressures in the internal chamber than in the barrel and greater flexibility on pressure manipulation in the barrel and the projectile, allowing for a more efficient propellant combustion and manipulation of projectile characteristics such as muzzle and rotational speeds.

摘要： A method of making a projectile apparatus is provided that includes making one or components of the apparatus using an additive manufacture technique such as 3-D printing or laser-aided additive manufacture. The projectile apparatus can have a projectile, a propellant, and one or more optional components such as a wading, a sabot, and an intermediary device. The projectile can be fired through a barrel having a smooth bore. Additive manufacture methods can be used that involve forming components from superalloys having nanoparticles incorporated therein. The projectile apparatus can convert gas pressure or gas velocity into a high rate of projectile spin. The projectile has long-range accuracy due to a high or sustainable velocity and high rate of spin.

摘要： The Spin-stabilized Projectile for Smoothbore Barrels would provide for improved accuracy and a flatter trajectory in comparison tot current Foster design projectiles or statically stabilized finned projectiles. The method achieved for spin stabilization here can easily be up-scaled for larger caliber artillery projectiles for when a spin-stabilized projectile is desired from a smoothbore weapon.
