Abstract
A flapping wing flying device comprises wings that pivot about a pivot axis extending generally perpendicularly to an elongate body of the flying device, and wings that move relative to said elongate body of the flying device, so that the entire leading edge of each of the wings is moved away from and toward to the body of the flying device during flight.
Claims21
A flying device comprising:
- a frame adapted for supporting a pilot thereon;
- an airfoil including a leading edge and a trailing edge, said airfoil adapted for pivotal movement about a pivot axis extending through said leading edge and said airfoil adapted for movement of the leading edge of the airfoil away from said frame;
- means for pivoting said airfoil about said pivot axis;
- and
- means for moving said leading edge of said airfoil away from said frame.

A flying device comprising:
- a frame adapted for supporting a pilot thereon;
- an airfoil including a leading edge and a trailing edge, said airfoil adapted for pivotal movement about a pivot axis extending through said leading edge and said airfoil adapted for movement of the leading edge of the airfoil away from said frame;

- and
- wherein said dampening means is chosen from the group consisting of a spring, an elastic rope, and a stretchable airfoil.

A flapping wing aircraft comprising:
- a frame;
- an airfoil operatively connected to said frame;
- and
- means for moving said airfoil sequentially away from and toward said frame during flight;

2 more elements
A flapping wing aircraft comprising:
- an aircraft frame including a base movable toward and away from a remainder of said frame;
- a wing secured to said base, said wing being moved toward and away from said frame as said base is moved toward and away from said remainder of said frame, wherein movement of said wing toward and away from said remainder of said frame provides flapping wing movement of said wing so as to provide lift and propulsion for said aircraft;
- and
- a pulley system connected to a movable foot pedal of said frame for moving said wing away from and toward said frame.
