A missile is provided with a motor section that is separated from a guidance and control section by a roller bearing section. A shaft connected to the motor section extends through the roller bearing section and connects to a gear unit that drives a shaft connected to an electrical generator. As the missile moves in flight, vanes on the motor section catch air flow which causes the motor section to rotate. The kinetic energy of the motor section is then converted into electrical energy by the gear unit and electrical generator. A flight computer, a sensor and electro-mechanical actuators are supplied electrical energy from a voltage regulator connected to the electrical generator. The electro-mechanical actuators are connected to corresponding control fins which control the flight path of the missile.

A projectile package loaded in a firearm includes a projectile having a rod attached to its rear region. The rod is attached to a drag member or vanes having elastic properties. When fired, the projectile is expelled from the barrel of the firearm. Upon exiting the barrel and until the projectile reaches its effective range, reactionary air forces caused by the projectile traveling through the air result in the elastic vanes orienting themselves in a tight formation behind the rear region of the projectile. As a result, the vanes do not detrimentally affect the aerodynamics of the projectile's flight within the effective range of the projectile. However, once the effective range of the projectile has been exceeded, the slower velocity of the projectile causes the elastic vanes to laterally fan or spread out so as to impede the forward progress of the projectile.

A noise generator system is provided with each noise generator being pivotally mounted to a mounting surface associated with the air intake of a turbineless jet engine. Each noise generator is positioned so as to convert a laminar or transitional air stream into a turbulent air stream such that a turbulent air-fuel mixture is realized in the combustion section of the engine to achieve more efficient operation.

On-Board Power Generation System for a Guided Projectile eliminates the need for batteries as a power source to power the guiding mechanism residing inside the projectile. Instead, an electrical generator and a wind-driven turbine to drive the generator are utilized to produce power. In this way, a small portion of the projectile's kinetic energy is converted into electrical energy. The power thusly produced is, then, coupled to the guiding means. The projectile is appropriately configured to accommodate therein the power generaion system and air inlets and exhaust ports that are necessary to enable the system to operate.

A steel projectile assuming the general shape of a teardrop compensates for the lower density of the material as compared to lead and still achieves penetration into the target that is comparable to spherical lead pellets. Additional benefit of the elongated exterior geometry of the projectile is less scatter and less aerodynamic drag during flight.
