Abstract
A Mixer-Ejector Prop System (MEPS) is presented as a new, unique and improved concept for injecting power and producing force in flowing fluids such as air or water. MEPS incorporates advanced flow mixing technology, single and multi-stage ejector technology, aircraft and propulsion aerodynamics and noise abatement technologies in a unique manner to fluid-dynamically improve the operational effectiveness and efficiency for subsonic flow velocities.
Claims25
A device for generating force at low speed using air, water or other fluids comprising a shrouded axial flow propeller with a single or multistage mixer-ejector pump that employs advanced fluid mixing devices, such as mixer lobes or slots, incorporated into the exhaust system of the propeller shroud.
A device for generating force at low speed using air, water or other fluids comprising:
- a. an aerodynamically contoured primary shroud with a circular or non-circular inlet and outlet, surrounding a propeller;
- b. an aerodynamically contoured center-body;
- c. a propeller rotor to generate thrust
- d. a single or multi-stage ejector pump with circular or non-circular inlets and outlets, incorporated into the exhaust system of the propeller shroud;
- e. ejector shrouds with circular or non-circular inlets and outlets
A device for generating force at low speed using air, water or other fluids comprising:
- a. an aerodynamically contoured primary shroud with a circular or non-circular inlet and outlet, surrounding a propeller;
- b. an aerodynamically contoured center-body;
- c. a propeller system made up of one or more stator rows, and one or more rotor blade rows that are mechanically linked at their inner rim to a power source;
- d. a single or multi-stage ejector pump incorporated into the exhaust system of the propeller shroud.
- e. ejector shrouds with circular or non-circular inlets and outlets that are aerodynamically cambered to increase flow through the propeller rotor.
