Annular ring wing Vario Copter
BG and EN .pdf presentation download here
The asymmetric reduction in the area of the oval wing maintains zero wingtip induced drag (37% of total drag), but reduces its lift. It is over-compensated by the wing's lower self-mass and lower skin friction drag, due to its reduced wing surface area and dimples (similar to the dimples on golf balls) on its underside. We obtained such definitive results from laboratory measurements on wind and hydrokinetic turbines with similar elliptical blades

Drones have gained popularity because of the suitability for a
broad range of applications. Drones are Unmanned Aerial Vehicles
(UAV) and may be used for aerial photography, product deliveries,
military operations, agriculture, policing and surveillance,
infrastructure inspections, and science. The design variation
among drones is vast and may be categorized according to
configuration, engine type and operational role. For example,
the configuration of drones may be fixed winged, blended
wing-body designs or flapping-wing ornithopters. The engine
design may be internal combustion, jet engine, rotary engines,
piston engines or electric engines. Small drones mostly use
lithium-polymer batteries while some larger drones use hydrogen
fuel cells. The design of the drone may enable it to be used as
a base station for providing wireless communication to
subscribers or user equipment.
Annular winged DRONE
is
a world patent novelty,
according to the official patent
statement, which you can download from HERE
The
patented VarioCopter™ takes-off and lands vertically. With the
same propeller motors, flies horizontally as a winged aircraft,
This is the most economical aerodynamic scheme that provides the
most energy-efficient flying in all flight modes. Because the
wing has no periphery - there is no any peripheral vortex air
drag and therefore it has zero energy losses. At the same time,
it has all the advantages of conventional drones
