An improved personal propulsion device that generally imparts thrust directly to the user. The device allows hands free control of thrust magnitude and direction so both hands can grasp and control bicycle handlebars and brakes, watercraft paddles, ski poles, etc. The device is adjustable vertically
An improved personal propulsion device that generally imparts thrust directly to the user. The device allows hands free control of thrust magnitude and direction so both hands can grasp and control bicycle handlebars and brakes, watercraft paddles, ski poles, etc. The device is adjustable vertically, on the users' back, higher to allow sitting in a canoe or wheelchair and lower for standing on skates, skis, kick scooters etc. A user on a bicycle may prefer to lean forward for comfort and aerodynamics, a device adjustment compensates and delivers level thrust. A user on a snowboard or skateboard stands oblique to the direction of travel, a device adjustment allows in line thrust. Both users' hands and arms are free to balance, protect others by pushing off or break a fall.

I claim: 1. A backpack propulsion device with propulsion means imparting thrust directly to a user's back, the improvement in wherein said device has a throttle control means for hands free control of thrust magnitude and direction of thrust, said throttle control means comprising a glove configure
I claim: 1. A backpack propulsion device with propulsion means imparting thrust directly to a user's back, the improvement in wherein said device has a throttle control means for hands free control of thrust magnitude and direction of thrust, said throttle control means comprising a glove configured for one or more fingers, said glove operatively connected to the device throttle, start/stop and thrust direction by wireless remote control means. 2. The device of claim 1, wherein said glove is detachable from mechanical and or electrical connections to allow interchangeability of various sizes, colors or insulation features of said glove. 3. The device of claim 2 further comprising a propeller or turbine connection means to the propulsion means by a centrifugal clutch so motion stops when engine is at idle. 4. The device of claim 3 further comprising an energy absorbing bumper disposed around a propeller shroud for a propeller, said bumper configured to improve airflow into the propeller by rounding an air inlet end of the shroud. 5. The device of claim 4, wherein the bumper is made of a stretchable material and can be inflated to increase thrust at low speeds and increase buoyancy for water craft use and safety. 6. The device of claim 4, wherein one or more lightweight panels of semi rigid material are configured and disposed in locations to cooperate with air flow around the user and into the propeller to improve thrust efficiency. 7. The device of claim 6 further comprising one or more user support straps, said user support straps being adjustable to allow the user to raise the device high on the user's back, to the middle of the user's back, or lower on the user's back. 8. The device of claim 7 further comprising a means for securing the device rotatably about a vertical axis of the user for hands free oblique thrust relative to the user. 9. The device of claim 8 further comprising a recoil rope starter handle extension means operatively attached to the propulsion means, said handle extension means having a starter pull handle is disposed on a shoulder strap just above the breast position of the user for easy grasp and pull of said pull handle in all positions of said device adjustments, both ends of the starter handle extension means being flexible and unattached to a frame of said device except in the center of the handle extension means. 10. The device of claim 9, wherein the propulsion means is pivotably attached to the frame about a horizontal axis allowing level, upward, or downward thrust substantially inline with the user's direction of travel, and in cooperation with various user positions. 11. The device of claim 10, further comprising a pivot block attached to the frame, said pivot block configured to allow interchangeability of the propulsion means. 12. The device of claim 1, wherein said propulsion device comprises a propeller shroud disposed around a propeller, said propeller shroud having a plurality of support spokes connected thereto by a spoke nut configured to allow adjustment of said propeller shroud relative to said propeller to adjust clearance therebetween. 13. The device of claim 1, wherein said throttle control means further comprises a finger end cap operatively connected to the device throttle, said finger end cap configured to be disposed on an end of a finger of the user. 14. A backpack propulsion device with propulsion means imparting thrust directly to a user's back, the improvement wherein said device has a throttle control means for hands free control of thrust magnitude and direction of thrust, said throttle control means comprising a glove configured for one or more fingers, said glove operatively connected to the device throttle, said glove detachable from mechanical and or electrical connections, said device further comprising an energy absorbing bumper disposed around a propeller shroud for a propeller, said bumper configured to improve airflow into the propeller by rounding an air inlet end of the shroud, said bumper made of a stretchable material and configured to be inflated to increase thrust at low speeds and increase buoyancy for water craft use and safety. 15. The device of claim 14 wherein said glove is operationally connected to the device throttle, start/stop, and thrust direction by wireless remote control means. 16. The device of claim 14, wherein said propulsion device comprises a propeller shroud disposed around a propeller, said propeller shroud having a plurality of support spokes connected thereto by a spoke nut configured to allow adjustment of said propeller shroud relative to said propeller to adjust clearance therebetween. 17. A backpack propulsion device with propulsion means imparting thrust directly to a user's back, the improvement wherein said device has a throttle control means for hands free control of thrust magnitude and direction of thrust, said throttle control means comprising a glove configured for one or more fingers, said glove operatively connected to the device throttle, said glove detachable from mechanical and or electrical connections, said propulsion means pivotably attached to the frame about a horizontal axis to allow level, upward or downward thrust substantially inline with the user's direction of travel, and in cooperation with various user positions. 18. The device of claim 17, wherein said propulsion device comprises a propeller shroud disposed around a propeller, said propeller shroud having a plurality of support spokes connected thereto by a spoke nut configured to allow adjustment of said propeller shroud relative to said propeller to adjust clearance therebetween. 19. The device of claim 17, further comprising a pivot block attached to the frame, said pivot block configured to allow interchangeability of the propulsion means. 20. The device of claim 17, wherein said throttle control means further comprises a finger end cap operatively connected to the device throttle, said finger end cap configured to be disposed on an end of a finger of the user.
