ASSEMBLY AND METHOD OF MANIPULATION OF AIRCRAFT POWER UNIT Russian patent published in 2023 - IPC B64F5/50 

FIELD: maintenance of aircraft power unit.

SUBSTANCE: power unit manipulation assembly contains a frame (35), three branches (63a, 63c) for manipulating the nacelle. The frame (35) has three levers spaced from each other in the radial direction. The frame (35) is rotatable around an axis perpendicular to the longitudinal axis (41) of the manipulation unit. Manipulation branches (63a, 63c) are installed perpendicular to the levers (37a, 37c) of the frame (35), passing along the longitudinal axis, and include a movable working branch (65) configured to move between the initial position, providing a gap with the inner wall nacelle air intake, and an operating position in which said working branch comes into contact with said inner wall so as to apply a pressing force of said manipulation branches to the inner wall of the air intake.

EFFECT: possibility of using the manipulation unit on nacelles having a laminar-type air intake is achieved.
