A propulsion system and method are described configured to exert a force upon a vehicle. The system includes a concentrated mass which may be discharged from the vehicle by a propellant typically via an ejection tube. The system is optimized so that the discharged concentrated-mass imparts a large impulse upon the vehicle. The system and method may be used to alter the momentum of vehicles for propulsion, attitude correction, vehicle separation and the like.

1. A propulsion system configured to exert a force and impart an impulse upon at least one vehicle, said system comprising: at least a first vehicle comprising at least one chamber containing propellant;at least one exhaust ejection tube connected to said at least one chamber, wherein said at least one exhaust ejection tube is non-conical; andat least one concentrated mass, at least partially located within said at least one exhaust ejection tube and configured to be discharged from said first vehicle through said at least one exhaust ejection tube when said propellant is activated so as to impart an impulse and a force upon said first vehicle in a direction opposite to the motion direction of said concentrated mass while moving within said at least one exhaust ejection tube, and wherein said concentrated mass is configured to travel along said at least one exhaust ejection tube before it is expelled from said first vehicle. 2. The propulsion system of claim 1, wherein the chamber is the inner volume of the at least one exhaust ejection tube through which said concentrated mass is discharged. 3. The propulsion system of claim 1, wherein said propellant comprises a fuel configured to generate high pressure products upon combustion. 4. The propulsion system of claim 1, wherein said propellant is selected from the group consisting of solid propellant, liquid propellant, compressed gas, and a combination thereof. 5. The propulsion system of claim 1, wherein said concentrated mass is entirely contained within said at least one exhaust ejection tube before it is ejected. 6. The propulsion system of claim 1 further comprising a loading mechanism, said loading mechanism being capable of introducing a new concentrated mass into said at least one exhaust ejection tube and introducing new propellant into said chamber, after said concentrated mass was discharged from said first vehicle through the at least one exhaust ejection tube. 7. The propulsion system of claim 1, wherein said concentrated mass is selected from the group consisting of a dead-weight, a discarded section of said first vehicle, a discarded case of a propellant charge, a traveling charge, a second vehicle, and combinations thereof. 8. The propulsion system of claim 1, wherein said first vehicle is selected from the group consisting of rockets, missiles, spacecraft, space stations, satellites, rocket stages, and combinations thereof. 9. The propulsion system of claim 1, further comprising a second vehicle, wherein the propulsion system is configured to separate said first vehicle from said second vehicle, wherein: said first vehicle serves as a first concentrated mass for propelling said second vehicle, andsaid second vehicle serves as a second concentrated mass for propelling said first vehicle. 10. The propulsion system of claim 9, wherein said first and second vehicles are selected from the group consisting of satellites, spacecraft, space stations, rocket stages, and combinations thereof. 11. The propulsion system of claim 1, wherein concentrated mass comprises at least one of the group consisting of solid masses, liquids, gels, powdered materials, and combinations thereof. 12. A separation system comprising: a first vehicle comprising: at least one chamber containing propellant; andat least a first tube connected to said at least one chamber, wherein said first tube has an open end;a second vehicle; anda separation mechanism, said separation mechanism comprising: said first tube, connected to said first vehicle; anda second tube, connected to said second vehicle, wherein said second tube has an open end,wherein said first tube and said second tube are nested one inside the other such that said open end of said first tube is inserted inside said open end of said second tube, such that, when said propellant is activated within said chamber, opposing forces are exerted upon said first vehicle and upon said second vehicle thereby separating said first vehicle from said second vehicle. 13. The propulsion system of claim 1, wherein a series of pulse systems are installed where each system is applied as the concentrated mass of the next pulse round. 14. A method for imparting an impulse and a force upon a vehicle, said method comprising: providing a first vehicle having a propulsion system comprising: at least one chamber, capable of containing propellant;at least one exhaust ejection tube connected to said at least one chamber, wherein said at least one exhaust ejection tube is non-conical; andat least one concentrated mass, at least partially located within said at least one exhaust ejection tube, and configured to be discharged from said first vehicle through said at least one exhaust ejection tube when said propellant is activated so as to impart an impulse and a force upon said first vehicle in a direction opposite to the motion direction of said concentrated mass while moving within said at least one exhaust ejection tube, and wherein said concentrated mass is configured to travel along said at least one exhaust ejection tube before it is expelled from said first vehicle; andactivating said propellant within said chamber thereby causing the discharge of said at least one concentrated mass from said at least one exhaust ejection tube. 15. The method of claim 14, wherein activating said propellant comprises igniting said propellant. 16. The method of claim 14, wherein said propellant comprises a compressed gas, and activating said propellant comprises releasing said compressed gas. 17. The method of claim 14 wherein said concentrated mass is entirely contained within said at least one exhaust ejection tube and wherein said concentrated mass is discharged through the at least one exhaust ejection tube. 18. The method of claim 14, wherein said concentrated mass is selected from the group consisting of a dead-weight, a discarded section of said first vehicle, a discarded case of a propellant charge, a traveling charge, a second vehicle, and combinations thereof. 19. A propulsion system configured to exert a force and impart an impulse upon at least one vehicle, said system comprising: at least a first vehicle comprising: at least one chamber containing propellant;at least one exhaust ejection tube connected to said at least one chamber, wherein said at least one exhaust ejection tube has an open end; andat least one concentrated mass, at least partially located within said at least one exhaust ejection tube, and configured to be discharged from said first vehicle through said at least one exhaust ejection tube when said propellant is activated so as to generate compressed gas and impart an impulse and a force upon said first vehicle in a direction opposite to the motion direction of said concentrated mass while moving within said at least one exhaust ejection tube,wherein said at least one exhaust ejection tube has a section of a constant internal diameter, andwherein the length of said section of a constant internal diameter is at least three times said constant diameter. 20. The propulsion system of claim 19, wherein said concentrated mass is configured to travel along said at least one exhaust ejection tube for a distance of at least three times said constant diameter. 21. The propulsion system of claim 19, wherein said concentrated mass is a second vehicle. 22.
