A control system for a flying vehicle in an atmospheric environment, the vehicle having an aerodynamic shape including a front end and a rear end including a plurality of attitude control jet nozzles spaced outward from the vehicle near the rear end of the vehicle or a trailing edge of a vehicle par
A control system for a flying vehicle in an atmospheric environment, the vehicle having an aerodynamic shape including a front end and a rear end including a plurality of attitude control jet nozzles spaced outward from the vehicle near the rear end of the vehicle or a trailing edge of a vehicle part; and a generator for providing a low mass flow of a fluid through the attitude control jet nozzles to create an area of high pressure immediately forward of the nozzles and adjacent the flying vehicle, wherein the location of the attitude control jet nozzles is so close to the rear end of the vehicle that any area of low pressure created by the low mass flow of fluid through the attitude control jet nozzles does not contact the vehicle.

1. A control system for a flying vehicle in an atmospheric environment, the vehicle having an aerodynamic shape including a front end and a rear end, said control system allowing the overall weight and equipment to be reduced in the vehicle, comprising:(a) a plurality of attitude control jet nozzles
1. A control system for a flying vehicle in an atmospheric environment, the vehicle having an aerodynamic shape including a front end and a rear end, said control system allowing the overall weight and equipment to be reduced in the vehicle, comprising:(a) a plurality of attitude control jet nozzles directed outward from the vehicle, said nozzles being located at the extreme end of the vehicle or the trailing edge of a vehicle part, said nozzles arranged in groups in lines orthogonal to the main axis of the vehicle, wherein the shape of said nozzles is selected from the group of regular geometric shapes;(b) means for providing a fluid flow through said nozzles, said fluid flow creating an area of high pressure immediately forward of said nozzles and adjacent to said vehicle;(c) said nozzles located at the extreme end or the trailing edge of a vehicle part so that any area of low pressure created by said fluid flow through said nozzles does not contact said vehicle; and,(d) said nozzles being dimensioned and configured to provide a similar force as a single attitude jet nozzle while utilizing a fluid flow substantially less than that of said single attitude jet nozzle achieving a similar alternation of the flight path of the vehicle, allowing the overall weight and equipment to be reduced in the vehicle. 2. The control system of claim 1, wherein the number of said nozzles ranges from 2 to about 31 arranged in each group. 3. An aerodynamic, reaction jet-powered vehicle having a vehicle body including a front end and a spaced-apart rear end aligned along a main axis of the vehicle, said vehicle designed for controlled flight in an atmospheric environment, said vehicle having a jet control system for controllably altering the flight path of the vehicle, said control system allowing the overall weight and equipment of said vehicle to be reduced in the vehicle, comprising:(a) a plurality of attitude control jet nozzles directed outward from the vehicle, said nozzles being located at the extreme end of the vehicle or the trailing edge of a vehicle part, said nozzles arranged in groups in lines orthogonal to the main axis of the vehicle, said groups spaced equally in quadrants about the vehicle, wherein the shape of said nozzles is selected from a group of regular geometric shapes;(b) means for providing a fluid flow through said nozzles, said fluid flow creating an area of high pressure immediately forward of said nozzles and adjacent to said vehicle to augment the reactive force generated by said nozzles upon the vehicle;(c) means for controlling the onset, termination, and amount of said flow of fluid to each said nozzles or each of said groups separately to alter the flight path of the vehicle; and,(d) said nozzles being dimensioned and configured to provide a similar reactive force as a single attitude jet nozzle while utilizing a fluid flow substantially less than that of said single attitude jet nozzle achieving a similar alternation of the flight path of the vehicle, allowing the overall weight and equipment to be reduced in the vehicle. 4. The control system of claim 3, wherein the number of said nozzles ranges from 2 to 3 in each quadrant. 5. The control system of claim 4 wherein 21 of said nozzles are utilized in each quadrant, at a spacing of 2 nozzle diameters apart.
