Personal propulsion device
DCFirst Claim
1. A personal propulsion device, comprising:
- a body unit having a center of gravity, wherein the body unit includes a thrust assembly having at least two thrust nozzles located above the center of gravity;
a delivery conduit in fluid communication with the thrust assembly; and
a base unit in fluid communication with the delivery conduit, the base unit capable of delivering pressurized fluid to the delivery conduit;
wherein the base unit includes a pump, the pump being in fluid communication with the delivery conduit;
wherein the pump can provide a mass flow rate of water to the thrust assembly sufficient to lift 200 pounds a height of 30 feet for a sustained period of time.

Abstract
The present invention provides a personal propulsion device including a body unit having a center of gravity, where the body unit includes a thrust assembly providing a main conduit in fluid communication with at least two thrust nozzles, with the thrust nozzles being located above the center of gravity of the body unit. The thrust nozzles are independently pivotable about a transverse axis located above the center of gravity, and may be independently controlled by a single common linkage. The present invention may further include a base unit having an engine and a pump, which provides pressurized fluid to the body unit through a delivery conduit in fluid communication with both the base unit and the thrust assembly.
