A mechanism (100) for transitioning a tiltrotor aircraft (10) between rotary and non rotary flight modes. The mechanism (100) includes a gimbal lock (130) positioned about a mast (104) that is operable to selectively enable and disable a gimballing degree of freedom of a rotor assembly (102) relative to the mast (104). A blade stop assembly (140), positioned about the mast (104), includes a plurality of arms (142) having a radially contracted orientation and a radially extended orientation. A blade lock assembly (150) is operably associated with each rotor blade assembly (112). Each blade lock assembly (150) is operable to selectively enable and disable a folding degree of freedom and a pitching degree of freedom of the respective rotor blade assembly (112). A swash plate (120) is operable to change the pitch of the rotor blade assemblies (112) in the rotary flight mode and fold the rotor blade assemblies (112) in the non rotary flight mode.
