Abstract:
1. A vertical take-off and landing aircraft, comprising: an airframe body; said airframe body including a first frame positioned on a first side of said aircraft, said first frame being longitudinally disposed and vertically-oriented; said airframe body including a second frame positioned on a second side of said aircraft, said second frame being longitudinally disposed and vertically-oriented; said first and second frames being parallel to one another and being transversely spaced apart from one another; said first frame including a top horizontal part having a leading end and a trailing end, a bottom horizontal part having a leading end and a trailing end, a forward, leading arcuate part that interconnects respective leading ends of said top and bottom parts, a forward, trailing arcuate part that interconnects respective leading ends of said top and bottom parts, a rearward, leading arcuate part that interconnects respective trailing ends of said top and bottom parts, and a rearward, trailing arcuate part that interconnects respective trailing ends of said top and bottom parts; said second frame including a top horizontal part having a leading end and a trailing end, a bottom horizontal part having a leading end and a trailing end, a forward, leading arcuate part that interconnects respective leading ends of said top and bottom parts, a forward, trailing arcuate part that interconnects respective leading ends of said top and bottom parts, a rearward, leading arcuate part that interconnects respective trailing ends of said top and bottom parts, and a rearward, trailing arcuate part that interconnects respective trailing ends of said top and bottom parts; a plurality of wings disposed in interconnecting relation to said first and second frames, each wing being transversely disposed relative to a longitudinal axis of said aircraft and each wing having a first end movably connected to said first frame and a second, transversely opposed second end movably connected to said second frame; each wing having a leading end movably connected at its opposite ends to said first and second frames; each wing having a trailing end movably connected at its opposite ends to said first and second frames; said leading end of each wing following a loop-shaped path of travel that includes traversing said respective top horizontal parts of said first and second frames from a trailing end to a leading end, traversing said respective forward, leading arcuate parts of said first and second frames from said respective leading ends of said respective horizontal top parts to said respective leading ends of said respective horizontal bottom parts, traversing said respective horizontal bottom parts from said respective leading ends to said respective trailing ends, and traversing said respective, rearward leading arcuate parts from said respective trailing ends of said respective bottom horizontal parts to said respective trailing ends of said respective top horizontal parts to complete one rotation; and said trailing end of each wing following a loop-shaped path of travel that includes traversing said respective top horizontal parts from their respective trailing ends to respective leading ends thereof, traversing said respective forward, trailing arcuate parts from said respective leading ends of said respective horizontal top parts to said respective leading ends of said respective bottom horizontal parts, traversing said respective bottom horizontal parts from their respective leading ends to their respective trailing ends, and traversing said respective rearward, leading arcuate parts from the respective trailing ends of said bottom horizontal parts to respective trailing ends of said top horizontal parts to complete one rotation.
