Quote:
A coleopter is a type of Vertical Take-Off and Landing aircraft design where the fuselage is surrounded by an annular wing. The aircraft is intended to take off and land on its tail. The term is an anglicisation of the French coléoptère (beetle) after the first actual implementation of this design, the SNECMA Coléoptère of the mid 1950s.

Abstract:
For an aircraft (1) having a balancing torque and including a motor-driven propeller (5) arranged on a central axis (3), and a useful load container (6), a solution should be provided which would insure that the aircraft is capable of carrying useful loads in a stable flying attitude and with simple control means.

This is achieved by that the central propeller (5) driven by the drive motor (4), on one hand, and relative thereto, the motor (4) and/or torque-balancing means arranged thereon, on the other hand, are rotatable in opposite directions and together are supported for rotation relative to the useful load container.

Not a coleopter, but a snazzy Flying Platform!

Hope this helps.
