Hidden door thrust reverser system for an aircraft propulsion system

A thrust reverser system for an aircraft propulsion system, comprising:

• a sleeve configured to translate in an aft direction along a centerline from a sleeve stowed position to a sleeve deployed position;
• a fixed cascade structure disposed within an interior cavity of the sleeve when the sleeve is in the sleeve stowed position;
• a blocker door configured to move between a blocker door stowed position and a blocker door deployed position, the blocker door disposed within the interior cavity of the sleeve when the sleeve is in the sleeve stowed position and the blocker door is in the blocker door stowed position, and the blocker door projecting in a radial inward direction away from the sleeve towards the centerline when the sleeve is in the sleeve deployed position and the blocker door is in the blocker door deployed position;
• and
• a blocker door actuation assembly configured to initiate movement of the blocker door from the blocker door stowed position to the blocker door deployed position while the sleeve is translating in the aft direction and the sleeve is at a sleeve intermediate position between the sleeve stowed position and the sleeve deployed position, wherein the blocker door actuation assembly comprises a scissor-type linkage.

A thrust reverser system for an aircraft propulsion system, comprising:

• a translating component configured to translate in a first direction along a centerline from a component first position to a component second position, wherein a component intermediate position is between the component first position and the component second position;
• a blocker door configured to move between a blocker door stowed position and a blocker door deployed position, the blocker door comprising a pivot attachment fixed at an end of the blocker door;
• a fixed guide comprising a first lateral track, a second lateral track and an axial track;
• a first lateral track slider configured to laterally translate along the first lateral track;
• a second lateral track slider configured to laterally translate along the second lateral track;
• an axial track slider configured to axially translate along the axial track, the axial track slider configured to move the pivot attachment;
• a latch laterally between the first lateral track slider and the second lateral track slider, the latch configured to temporarily engage the translating component as the translating component translates from the component intermediate position towards the component deployed position;
• a first slider-to-slider link extending between and pivotally connected to the first lateral track slider and the axial track slider;
• a first slider-to-latch link extending between and pivotally connected to the first lateral track slider and the latch;
• a second slider-to-slider link extending between and pivotally connected to the second lateral track slider and the axial track slider;
• and
• a second slider-to-latch link extending between and pivotally connected to the second lateral track slider and the latch.
