SNECMA C.450 Coléoptère Annular-Wing Tail-Sitter VTOL Prototype Family

The SNECMA C.450 Coléoptère was an experimental French annular-wing tail-sitter VTOL aircraft developed from SNECMA's C.400 P-2 Atar Volant. Its circular wing and vertically mounted jet concept were intended to combine vertical takeoff and landing with a transition to conventional forward flight, making it a distinct research family rather than a conventional production aircraft.
