Abstract
Heavier-than-air, aircraft having flapping wings, e.g., ornithopters, where angular orientation control is effected by variable differential sweep angles of deflection of the flappable wings in the course of sweep angles of travel and/or the control of variable wing membrane tension.
Claims5
An air vehicle, comprising:
- a processor;
- at least one drive motor in communication with the processor;
- a first flapping wing in communication with one of the at least one drive motor;
- and
- a second flapping wing in communication with one of the at least one drive motors;
- wherein the processor and the at least one drive motor are configured to drive the first and second flapping wings to provide lift and control moments without the benefit of either horizontal or vertical stabilizers;
- wherein the processor is configured to provide commands resulting in first and second wing movement selected from the group consisting of:
- variable differential sweep angles of deflection of the first and second flappable wings in the course of respective sweep angles of travel, variable differential luffing of the respective first and second flapping wings, and variable and differential angular velocity of the respective first and second flapping wings.
