Abstract: A control system for an ammunition having a longitudinal axis and adapted to move in a flight direction, particularly a wingless ammunition falling in ballistic flight, comprises a body having a rear curved surface with a gas generator in the body for producing gas under pressure. A nozzle is mounted to the body and oriented to direct a gas jet produced from the pressurized gas rearwardly and tangentially over the curved surface with respect to the flight direction of the ammunition. The gas jet produces reduced pressure on its side of the ammunition to alter the flight thereof.

Abstract: A fastening device for externally coupling suspended loads on an aircraft ving a pair of support arms pivotally mounted to a lifting device arranged therebetween for moving the support arms relative to a housing having abutments engaging the support arms so that by actuation of the lifting device the support arms are brought against the abutments and thereby urged into engagement with a load.
