Movable parabolic aerial engaging device for maritime patrol aircraft, has arm with end articulated to aerial that is movable in rotation around elevational axis and is originated around axis, where axes are remote from one another

摘要

#CMT# #/CMT# The device has an arm with an end connected to exterior of a fuselage (2) of a maritime patrol aircraft. The arm has another end on which a movable parabolic aerial (1) is articulated, where the aerial is movable in rotation around an elevational axis (10) by a motorization device (12), and is originated around an axis (7) passing by focal point of the parabola. The axes are remote from one another. The aerial is installed under the fuselage and protected at the interior of a radome. Another motorization device (13) allows the movement of the aerial around a circular rotational axis (11). #CMT#USE : #/CMT# Device for engaging a movable parabolic aerial under a fuselage of a maritime patrol aircraft. #CMT#ADVANTAGE : #/CMT# The device installs the aerial under the fuselage of the aircraft when a landing gear is small, and increases the dimensions of the aerial installed under the fuselage of the aircraft. The device reduces the envelope volume of movements of the aerial, thus reducing the dimension of the radome protecting the antenna and its overflow with respect to the skin of the aircraft. The radome has less aerodynamic drag during the flight of the aircraft. The device allows the movements of the aerial at the interior of the radome. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a movable parabolic aerial engaged using a movable parabolic aerial engaging device. 1 : Movable parabolic aerial 2 : Fuselage 6 : Parabolic shaped reflector 7 : Axis 10 : Elevational axis 11 : Circular rotational axis 12, 13 : Motorization devices.
