Abstract: A thrust reverser system for a turbine engine includes a support structure, a transcowl, a door, a lock, and a first elastic element. The transcowl is mounted on the support structure and is translatable between a stowed position, a deployed position, and an over-stow position. The door is pivotally coupled to the support structure and is rotatable between at least a first position, a second position, and a third position. The lock is movable between a locked position, to prevent transcowl translation toward the deployed position, and an unlocked position, to allow transcowl translation toward the deployed position. The lock is only able to move to the unlocked position when the transcowl is in the over-stow position. The first elastic element is disposed within the stowed position aperture and, when engaging both the support structure and the transcowl, supplies a force to the transcowl.

Abstract: A thrust reverser system for a turbine engine includes a support structure, a transcowl, a door, and an anti-rotation structure. The transcowl is mounted on the support structure and has an inner surface. The transcowl is axially translatable, relative to the support structure, between first and second positions. The door is pivotally coupled to the turbine engine, and has a forward edge and an aft edge. The door is rotatable between stowed and deployed positions when the transcowl translates between the first and second positions, respectively. The anti-rotation structure extends from the transcowl and is disposed adjacent to the aft edge of the door when the transcowl is in the first position and the door is in the stowed position. The anti-rotation structure is configured such that door rotation out of the stowed position only occurs subsequent to or concurrently with translation of the transcowl out of the first position.

Abstract: A thrust reverser system for a turbine engine includes a support structure, a transcowl, and a door. The transcowl is mounted on the support structure and is axially translatable, relative to the support structure, between first and second positions. The door is pivotally coupled to the support structure and is rotatable, about a pivot axis, between stowed and deployed positions when the transcowl translates between the first and second positions, respectively. The door has an internal surface and a balance plane, and pressure forces acting along the balance plane effectively creates no moment about the pivot axis. The internal surface of the door has a first surface area forward of the balance plane and a second surface area aft of the balance plane, and the second surface area substantially exceeds the first surface area.
