A coleopter is a type of VTOL aircraft design that uses a ducted fan as the primary fuselage of the entire aircraft. Generally they appear to be a large barrel-like extension at the rear, with a small cockpit area suspended above it. Coleopters are generally designed as tail-sitters. 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.
