Questions to discuss


Are any systems missing (and do you have better examples of each)?


What are the major design trade-offs in these systems?

What systems have development potential




The list

-- Dedicated lift jets

-- Rotated aircraft / rotated fuselage / tail-sitter

-- Vectored thrust (jet engine)

-- Propulsive wing (distributed)

-- Tilt-prop (upward or downwards)

-- Tilt rotor (or ducted fan) / tilt-wing / tilt-engine (jet)

-- Decoupled prop (e.g. X-2 and X-3 demonstrators)

-- Distributed Electric Fans
