1. A propulsion device comprising:
a) a frame having a pair of support arms secured thereto which are aligned parallel to one another; b) a first mechanism secured to said frame which can provide linear motion to a device interacting therewith; c) a drive mechanism capable of rotating said first mechanism; d) a pair of wing assemblies aligned parallel to one another while in an initial orientation, each wing assembly having a pair of end members and a pair of side members, each of said pair of side members being secured to said pair of end members to form a structure enclosing a surface area, and a wing extending over at least a portion of said surface area; e) a counterweight assembly secured to each of said pair of wing assemblies, each of said counterweight assemblies having a pair of arms each with a first end and a second end, each of said first ends having a weight secured thereto and each of said second ends being rotatably secured to one of said pair of side members, and each of said arms having a point located between said first and second ends which is rotatably attached to one of said pair of support arms; and f) a pair of locking devices secured to each end of said pair of end members on each of said pair of wing assemblies, each pair of said locking devices being positioned outboard of said pair of side members of each of said pair of wing assemblies, said locking devices temporarily engaging said first mechanism and capable of being moved linearly such that as two pairs of said locking devices disengage from said first mechanism each of said pair of wing assemblies will be free to rotate relative to its counterweight assembly, and after each of said pair of wing assemblies rotates through a set number of degrees, said two pairs of said locking devices will again engage with said first mechanism, and a continuation of such action by said pair of wing assemblies will generate lift. |
