Abstract
The invention comprises a rotary engine apparatus and method of use thereof. The rotary engine comprises a rotor configured to rotate in a housing and a set of vanes separating a volume between the rotor and housing into a set of chambers. Each of the vanes are dynamically controlled, such as through use of a stressed sheet and/or electromechanical means, to: (1) yield a greater radially outward and/or sealing force to the housing at start-up and/or at low engine speeds and (2) dynamically reduce radially outward and/or sealing forces at higher engine speeds.
Claims7
An apparatus, comprising:
- an engine, comprising:
- a housing;
- a rotor configured to rotate within said housing;
- a set of vanes configured to rotate with said rotor, said set of vanes configured to divide a volume between said rotor and said housing into a set of chambers, said set of vanes comprising a first vane, said first vane comprising:
- a stressed sheet, said stressed sheet configured to apply a radially outward force on a section of said first vane toward said housing;
- electromechanical means for controlling extension of said first vane toward said housing;
- at least three turning elements, said stressed sheet at least partially circumferentially wound about each of said at least three turning elements;
- and
- at least one wall configured to guide said stressed sheet.
