Abstract: To improve the steering of autonomous missiles with respect to great thrusts and a large number of guide pulses, preferably in a caliber range of less than 100 mm, fluidic wall jet elements are provided in branching conduits which are connected to radially directed steering nozzles and which are disposed in a plurality, for example, four, of control discs arranged one behind the other within the missile. The respective fluidic wall jet elements permit a sudden change in direction in a respective branching conduit of a hot gas stream generated by a gas generator. This makes it possible to generate, for example, a change in the direction of the gas stream from one steering nozzle to an oppositely disposed steering nozzle. A plurality of miniature flame capsules or compressed gas cartridges are arranged in a space saving manner in at least one disc-shaped recess as the actuators for the fluidic wall jet elements. The actuators ensure individual or joint actuation of steering nozzles arranged, for example, at 90.

Abstract: A device for the limitation of gas pressure in a projectile having an outer shell by the production of a control stream comprises a combustion chamber disposed inside the projectile; the combustion chamber having a combustion chamber lid; control lines connected to be changed by gas from the combustion chamber for transferring the gas pressure from the combustion chamber; monostable fluidic elements being arranged in the control lines in a region of the combustion chamber lid for assisting in confining the control stream; branching lines disposed in the lid and connected with the monostable fluidic elements, the branching lines including vent openings in the outer shell for releasing gas to the atmosphere and an overpressure element for permitting gas to be expelled from the combustion chamber when an overpressure exists therein, whereby gas expelled via the overpressure element assists in the production of the control stream.

Abstract: A pressure relief valve arrangement forming a combination with a pyrotechnic gas generator having a housing; a combustion chamber enclosed by the housing; a pyrotechnic propellant charge disposed within the combustion chamber; control nozzles disposed in the housing and communicating with the exterior of the housing; gas channels connecting the combustion chamber with the nozzles; valve devices for opening and closing the gas channels; and a control member for actuating the valve devices.

Abstract: A pressure relief valve for a hot gas generator is constructed as a valve arrangement which can be subjected to high temperature shocks and abrasion causing gaseous streams. The valve arrangement is constructed so as to have a prolonged operative life despite such operative demands, whereby simultaneously the predetermined pressure resistance for this valve arrangement is precisely maintained. For this purpose the valve arrangement includes a piston of substantially longitudinal cylindrical shape which has hemispherically shaped ends. A coil spring is operatively maintained behind the piston between a pair of end pieces which bias the piston towards a combustion chamber. The valve arrangement includes a valve body in which the piston is slidably moved. The valve body is made of a high temperature molybdenum alloy, whereas the piston, the seat and the end pieces for the coil spring 16 are made of a material having poor heat conduction characteristics, preferably silicon nitride.
