摘要

#CMT# #/CMT# The device has a telescopic arm (56) connected to a nacelle (30) and a door (46) by pivoting axles (58, 60), respectively, where the pivoting axles are parallel. The arm has a bent shape so that the door is arranged parallel and proximal to a fairing of the nacelle in opening position. The arm has two parts (70, 72) articulated with respect to the nacelle and the door, respectively, where the movement of center of gravity of the door is situated in a horizontal plane. #CMT#USE : #/CMT# Used for articulating a door to a nacelle of an aircraft (claimed), where the nacelle is utilized for adjusting and controlling the movements of air around and in an engine of the aircraft to optimize aerodynamic flow, for protecting the engine from external elements, for attenuating sound, for ventilating inner zones, for repairing mechanical efforts of the engine and for supporting advanced inversion system, and is connected to a wing by a mast. #CMT#ADVANTAGE : #/CMT# The telescopic arm is connected to the nacelle and the door by the pivoting axles, respectively, where the pivoting axles are parallel, thus permitting to space the door from the nacelle in order to facilitate access to the opening of the door. The length of the arm and the location of connection of the arm with the door can be adjusted to the dimensions of the door so that the door is spaced with respect to an opening of the nacelle in open position and entirely disengaged from the opening, thus permitting better access to the opening and protecting an operator between the nacelle and the door, and hence increasing the safety of the operator. The door is proximal to the fairing of the nacelle such that the door is resistant to the wind, thus reducing risk of sudden closing of the door. The movement of center of gravity is situated in the horizontal plane, thus reducing the risk of accidents caused by auto-closing of the door. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional schematic view illustrating the starting of an opening of a door of a nacelle of an aircraft. 30 : Nacelle 46 : Door 56 : Telescopic arm 58, 60 : Pivoting axles 70, 72 : Arm`s parts.
