The presently disclosed subject matter includes a system and a method for launching a projectile towards a target, wherein the system comprises a control circuitry, a booster engine, and one or more thrusters adapted to be connected to the projectile and capable of being spun during launch around a longitudinal axis of the projectile, the control circuitry being operatively connected to the one or more thrusters; wherein responsive to ignition of propellant stowed in a combustion chamber of the booster engine, the booster engine causes the projectile to launch from its cell; following launch of the projectile, the control circuitry is configured to activate one or more thrusters that cause the projectile to turn at a certain rate and a certain azimuth.

A method of increasing the performance of an aircraft, missile, munition or ground vehicle with plasma actuators, and more particularly of controlling fluid flow across their surfaces or other surfaces which would benefit from such a method, includes the design of an aerodynamic plasma actuator for the purpose of controlling airflow separation over a control surface of a aircraft, missile, or a ground vehicle, and a method of determining a modulation frequency for the plasma actuator for the purpose of fluid flow control over these vehicles. Various embodiments provide steps to increase the efficiency of aircraft, missiles, munitions and ground vehicles. The method of flow control reduces the power requirements of the aircraft, missile, munition or ground vehicle. These methods also provide alternative aerodynamic control using low-power hingeless plasma actuator devices.

The embodiments disclosed include a system comprising a missile segment having a hollow body with an external surface conforming to an external surface of a portion of a missile body. The missile segment comprises a plurality of slot thrust motor (STM) cavities arranged in the hollow body. Each STM cavity being elongated in a first direction relative to a longitudinal axis of the missile body. Each STM cavity includes a chamfered opening at one end of the STM cavity coincident with the external surface of the hollow body. The chamfered opening configured to expel a stream of a gas in a gas-flow direction which is at least one of perpendicular to and offset from the longitudinal axis. The embodiments also include a missile and method for producing a steering force.

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.

Embodiments disclosed include a system comprising a missile segment having an external surface conforming to a portion of an external surface of a missile body. The missile segment comprising a plurality of chemical plasma dispensing units (CPDUs) having a chemical plasma reactant (CPR). Each CPDU is addressable so that a group of selected CPDUs in an area is ignited simultaneously to cause a first reaction to push CPR particles into a flow stream surrounding the missile body. The CPR particles to complete a second reaction in the flow stream over a reaction time period to effectuate production of expanding hot gas energy caused by heating air in the flow stream and gaseous reaction products over the missile body to provide an amount of a steering force to change one or more of six degrees of freedom at a location on the body. A missile and method are also provided.

A drag reduction system, more specifically a forward mounted drag reduction system for use on an extended range artillery shell, includes a forward end comprising a fuse, an aft located base unit and located therebetween a shell body defining a cavity which comprises a payload, a forwardly located gas generator capable of generating a gas flow, and an ignition device to ignite the gas generator after the shell is launched.

A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. A particulate burner system can be used to combust fuel emission byproducts by injecting fuel and air into a housing having a bottom plate with a round bottom opening for burners to inject fuel into a combustion chamber and a top plate with a round top opening for exhausting fuel emissions. A thruster system can be used to propel munition for deep earth penetration by using a thruster system having a transfer cone connected to a munition body.
