Performance of ducted fans, suitable for lifting and propelling VTOL/S TOL aircraft is investigated; variations of duct angle, power required, and pitching moment obtained for force balanced conditions simulating level, unaccelerated, transition flight from 0 to 140 knots; tests made to determine effectiveness of movable vanes in duct.
