    • A supercavitating underwater projectile (10) adapted to be fired from a gun or the like, comprising a front end or nose portion (12) and a rear end portion (18). An auxilary rocket motor is disposed within the rear end portion (18) of the projectile (10) for providing additional thrust after the projectile (10) has been fired. Vents (28) are disposed within the projectile (10) and are in communication with the rocket motor and the exterior of the projectile (10) for venting some of the combustion gases from the rocket motor to the exterior of the projectile (10) near the nose portion (12) thereof to increase the size of the cavitation bubble formed as the projectile (10) travels through the water and thereby reduce hydrodynamic drag on the projectile.

    • A neural network controller (50) for a pulsed rocket motor tactical missile (10). The missile includes a fuselage or body (12), with a pulsed propulsion system (20). The pulsed propulsion system has a need for a logical control of the application of propulsion energy throughout the missle's flight. The controller (50) is trained to provide optimal initiation of individual rocket motor thrust pulses based on tactical information available at various points/times in the missle's flight. The controller training is through use of training cases, in which the network learns to output a specific target value(s) when specific values are input. When trained with a large sample of training cases selected from the multidimensional population of interest, the neural network effectively learns the correlations between inputs and outputs and can predict input/output relationships not previously seen in any traning case.

    • A projectile traversing the lower atmosphere at hypersonic speed suffers high aerodynamic drag. This may be reduced by preheating the air ahead of it to create a "plasma tunnel", within which the temperature is raised to several times the ambient with a corresponding reduction in density, reducing the drag force. Typically, overall drag may be reduced by a factor of 10-100 in this way. The heating may be accomplished in several ways. For example the projectile may be equipped with a prove attached to the nose through which liquid is sprayed. The liquid is brought to rest by the surrounding air, converting its kinetic energy to heat. A particular application is to electromagnetic space launch systems. A projectile accelerated to orbital or escape velocity at ground level by linear accelerator can traverse the atmosphere with acceptable speed loss.
    • 超音速穿越低层大气的射弹遇到高气动阻力。 这可以通过预热其前面的空气来产生“等离子体隧道”来减少,其中温度升高到环境温度的几倍,同时具有相应的密度降低,减小了阻力。 通常,通过这种方式,整体阻力可以降低10-100倍。 加热可以以几种方式实现。 例如,抛射体可以配备有附着在喷嘴上的鼻子的证明。 液体被周围的空气静止,将其动能转化为热量。 一个特别的应用是电磁空间发射系统。 通过线性加速器加速到轨道或地面的逃逸速度的弹丸可以以可接受的速度损失穿过大气。

    • A projectile (14) for an ammunition round (10) for use with a small arms or light firearm comprises an elongated projectile body (16). The projectile body (16) has first and second axially opposed ends (18, 20) respectively and a cavity (20) extending there between. The cavity is able to hold a quantity of propellant (24). A plurality of seals (26) extend about an outer surface of the body (16). The seals (26) protrude radially from the body (16) and operate to form a substantial seal against an inner circumferential surface of a barrel (12) of the firearm. Two of the seals (26b and 26c) are mutually adjacent and spaced apart in a direction of a longitudinal axis of the body to form a seal bound outer surface portion (36) of the body (16). One or more holes (38) are formed in the body (16) enabling fluid communication between the cavity (22) and the seal bound outer surface portion (36) of the body (16). This enables pressure equalisation inside and outside of the cavity (22) about the seal bound outer surface portion (36) when the projectile (14) is travelling through the barrel (12).
