Disclosed is a linkage mechanism (100) for driving an aircraft landing gear bay door, comprising: a primary torsion tube (10) comprising a first portion located inside a landing gear bay and a second portion outside the landing gear bay; a first drive apparatus connected between the first portion and a strut (201) of a landing gear (200) so as to transfer the driving force of the strut to the primary torsion tube (10); a secondary torsion tube (20) comprising an inner end portion located inside the bay and an outer end portion located outside the bay; a secondary drive apparatus connecting the primary torsion tube (10) and the secondary torsion tube (20) outside the bay; and two third drive apparatuses respectively connected between the inner end portion of the secondary torsion tube (20) and one of the bay doors. The secondary drive apparatus is located outside the landing gear bay, saving on space inside the bay, and reducing interference between motion mechanisms. A single side of the secondary torsion tube (20) transfers torque so that synchronism of the bay door is high. The number of components is reduced and power drive performance is high.

An icing detector probe includes three sections arranged sequentially along the direction of air flow, namely, a first section (I), a second section (II) and a third section (III). Wherein, the shape of the outer surface of the first section (I) is suitable for collecting droplets in the air flow; the shape of the outer surface of the second section (II) is suitable for full decelerating and releasing latent heat of large droplets during their movements; the outer surface of the third section (III) is suitable for icing of large droplets. The probe could distinguish and identify large droplets icing, thus effectively detecting it. Furthermore, it could effectively detect types of traditional icing, thus being helpful for exact detection of icing thickness. An icing detector including said icing detector probe is also provided.

An aircraft cockpit view enhancing system and method. The aircraft cockpit view enhancing system comprises: a central camera device (CC), a left camera device (LC), and a right camera device (RC), the central camera device (CC) being arranged between a driver eye site (E) and an aircraft windshield force column and having the shooting angle directly facing the aircraft windshield force column, and the left camera device (LC) and the right camera device (RC) being respectively arranged at the left side and the right side of the aircraft windshield force column and having the shooting angles respectively pointed and deflected to the right side and the left side of the aircraft windshield force column; an image processing device, used for performing image synthesis and image matching on a correct image, a left image and a right image shot by the central camera device (CC), the left camera device (LC) and the right camera device (RC), and acquiring an image of a shielding zone of the aircraft windshield force column; and a display device, used for displaying the image of the shielding zone of the aircraft windshield force column. The aircraft cockpit view enhancing system and method are able to accurately display an image of a shielding zone of a windshield force column and eliminate the defect of shielding the view of a cockpit by the windshield force column.

Disclosed is an integrated pylon structure for a propulsion system, wherein it is suitable for one end to be connected to an aircraft wing and the other end to be connected to an aircraft engine. The pylon structure comprises a pylon box section (110) formed from an upper and a lower beam, a frame (100) and a side wall panel (102). The pylon structure further comprises a thrust reverser hood connection structure, provided on the side wall and connected with a nacelle thrust reverser hood comprising a front fixed hood (301) and a rear movable hood (302). The thrust reverser hood connection structure comprises at least one guide rail used for guiding the rear movable hood to make the rear movable hood slide and open relative to the pylon box section. The engine thrust reverser hood is directly connected to the side wall of the pylon box section and the opening of the thrust reverser hood is guided by means of the guide rail on the side wall, thus a guide rail beam is eliminated, which saves on space while meeting the installation requirements of an engine and reduces the weight of the entire propulsion system.
