Claim:
1. A convertiplane comprising: a fuselage having a longitudinal axis; a forward-swept fixed wing extending laterally outward from both sides of the fuselage to wing tips spaced from the fuselage and having a static shape with non-articulating leading edges and non-articulating trailing edges along the lengths thereof; an aft-swept fixed wing extending laterally outward from both sides of the fuselage to wing tips spaced from the fuselage and having a static shape with non-articulating leading edges and non-articulating trailing edges along the lengths thereof; and an engine group rotatably attached adjacent to each tip of the forward-swept wing and adjacent to each tip of the aft-swept wing for transitioning between vertical flight and forward level flight, each engine group including at least one engine configured to generate a variably controllable thrust along a thrust axis, wherein each engine group is configured for independent rotation and independent changes in thrust relative to every other engine group to provide pitch, yaw, and roll control around the longitudinal axis of the fuselage without wing articulation during forward level flight.
