20140061388 | HELICOPTER CONTROL STICK SUPPORT ASSEMBLY - A support assembly for a helicopter control stick is provided. The support assembly includes a supporting structure and an instrument panel fixed to each other; and a connecting assembly for connecting the stick to the supporting structure. The connecting assembly includes an arm elongated in a longitudinal direction and having one end supporting the stick; a guide for connecting the arm in longitudinally sliding manner to the supporting structure, to move the end to and from the supporting structure; and a rotary assembly for connecting the arm to the supporting structure in rotary manner about a horizontal axis, to adjust the height of the end. The rotary assembly has a first releasable retainer, wherein the first releasable retainer operates to lock rotation of the arm with respect to the supporting structure in a desired angular position. | 03-06-2014 |
20110186691 | AIRCRAFT - An aircraft having at least one in-flight attitude control system, in turn having at least one actuator; and a hydraulic circuit connected to the actuator and having at least one pump designed to deliver a first flow when the pressure of the hydraulic circuit is above a presettable threshold value. The pump is designed to deliver a second flow greater than the first flow, and the aircraft has a sensor for detecting a quantity associated with the pressure of the hydraulic circuit; and a programmable central control unit, which controls the pump to deliver the second flow when the quantity detected by the sensor corresponds to a pressure of the hydraulic circuit below the threshold value. | 08-04-2011 |
20110163206 | HELICOPTER CONTROL STICK SUPPORT ASSEMBLY - A support assembly for helicopter control sticks has a supporting structure; an instrument panel fixed to the supporting structure; and a connecting device for connecting the sticks to the supporting structure. The connecting device has a longitudinally elongated arm fitted on one end with the sticks; and the arm slides to move the sticks to/from the supporting structure, and rotates about a horizontal axis to adjust the height of the sticks. | 07-07-2011 |
20110155845 | RETRACTABLE HELICOPTER LANDING GEAR - A retractable helicopter landing gear has a suspension structure supporting one wheel, and is movable between a withdrawn position, to reduce drag on the helicopter, and a lowered position for landing and takeoff of the helicopter. The landing gear also has a skid, which is located between the axis of rotation of the wheel and the periphery of the wheel, is diametrically opposite the suspension structure, and is connected to the suspension structure by a connecting device having a torsion bar. | 06-30-2011 |
20100096508 | Aircraft and method of retrieving a rescue cradle into the aircraft fuselage - An aircraft capable of hovering, and having a fuselage defining an access opening; driving means for operating a rescue cradle; and a first wall movable between a closed position engaging a first portion of the opening, and a first open position allowing access to the first portion of the opening. The aircraft has a member connected functionally to the first wall and in turn having at least one flat surface; and the member is movable with respect to the wall into a first position, in which the flat surface defines a supporting surface for the cradle when the first wall is in the first open position. | 04-22-2010 |
20100092299 | HELICOPTER ANTITORQUE TAIL ROTOR BLADE - A blade for an antitorque tail rotor of a helicopter, having a leading edge and a trailing edge opposite each other and elongated along a longitudinal axis of the blade; the trailing edge, in use, interacts with the air current after the leading edge; the blade also has an end portion extending between a reference section and a radially outer end of the blade with respect to a rotation axis of the blade; the rotation axis is outside the blade and crosswise with respect to the longitudinal axis; the length of the chord at the end portion decreases from the reference section to the radially outer end; and the leading and trailing edges are joined at the radially outer end. | 04-15-2010 |
20100092294 | HELICOPTER ANTITORQUE TAIL ROTOR - A blade for an antitorque tail rotor of a helicopter, having a leading edge and a trailing edge opposite each other and elongated along a longitudinal axis of the blade; the trailing edge, in use, interacts with the air current after the leading edge; the blade also has two opposite surfaces extending between the leading edge and the trailing edge, and a root portion extending from a radially inner first end, with respect to a rotation axis of the blade, towards a second end opposite the first end; and the root portion, when sectioned in a plane perpendicular to the leading edge and trailing edge, has a profile asymmetrical with respect to a chord joining the leading edge and trailing edge. | 04-15-2010 |
20100044508 | AIRCRAFT WING - A wing for an aircraft having at least one weapon, and a feed duct for feeding the weapon with ammunition supplied in the form of a belt; the wing has a compartment for housing a portion of the belt and connectable to a loading opening of the feed duct. | 02-25-2010 |
20100038469 | Helicopter rotor - A rotor for a helicopter, the rotor having a drive shaft rotating about a first axis; a hub connected functionally to the drive shaft in angularly fixed manner with respect to the first axis and in rotary manner with respect to a second axis crosswise to the first axis; and two blades connected to the hub in angularly fixed manner with respect to the first and second axis and in rotary manner with respect to respective third axes; the rotor also having supporting means for supporting the blades with respect to the hub in rotary manner about the respective third axes; the supporting means having at least one supporting member made at least partly of elastomeric material and interposed between a first surface and a second surface integral with a respective blade and the hub respectively; and the supporting member deforming, in use, to permit rotation of the blade, with respect to the hub, about the respective third axis.
