Abstract:
A wing flap control system on a wing comprising at least two control plates having an opening sized to accommodate a drive shaft, a drive shaft that engages each of the openings in each of the plurality of plates, a sprocket rotatively affixed the drive shaft with the drive shaft penetrating the other control plate, at least two idler sprockets between the control plates, a chain wrapped around the sprocket and idler sprockets, a support arm rotatively coupled to the chain by a chain shoe and to a foreflap, a link arm rotatively coupled to the support arm and to a flap, where movement of the drive shaft causes the foreflap and flap to extend and retract to increase or decrease the surface area of the wing.
Abstract:
An aircraft landing gear arrangement comprises a nose landing gear assembly (18) and at least one main landing gear assembly (20). The nose landing gear assembly (18) has a nose landing gear wheel (26) with a high energy brake apparatus therein. The main landing gear assembly has a main landing gear wheel (32b) with a high energy brake apparatus therein and a main landing gear wheel (32a) with a motor (44) therein. The motor is used for driving the main landing wheel during taxiing of the aircraft.
Abstract:
A method of retrofitting retractable floats to an aircraft such as a floatplane. The aircraft considered have existing landing gear such as wheeled landing gear to equip said aircraft to optionally takeoff or land on a solid surface such as a beach or landing strip, the method including the steps of: a) mounting at least one float retraction arm to the aircraft; and b) attaching the floats to the float retraction arm. Each float includes an air travel position in which it is secured close to the float retraction arm mounting location and/or the fuselage, and a deployed position in which the float is lower than the existing landing gear. Tn following the float retraction paths of travel of the float retraction arm and the floats between the air travel and deployed positions, the floats do not interfere with the existing landing gear or its operation.
Abstract:
Il s'agit d'un dispositif de mesure comportant au moins un capteur (20) destiné à être monté sur un élément mobile (8) par rapport à une base (14), l'élément mobile (8) étant apte à prendre plusieurs positions par rapport à la base (14) dont une dite de proximité dans laquelle il est proche de la base (14). Le capteur (20) coopère avec un dispositif d'alimentation en énergie comprenant, situées sur l'élément mobile (8), une source d'énergie rechargeable (22) équipée d'au moins une première antenne de charge (23-1), et située sur la base (14), au moins une seconde antenne de charge (23-2) devant être couplée à la première antenne de charge (23-1) pour recharger la source d'énergie rechargeable (22). Le couplage entre des deux antennes de charge (23-1, 23-2) se fait uniquement lorsque l'élément mobile (8) est dans la position de proximité.
Abstract:
The invention concerns an aircraft landing gear, comprising a strut (11) consisting of a strut assembly (12) wherein slides a telescopic rod (13) with axis (Z), said strut assembly being articulated on an aircraft structure capable of pivoting about an axis (X) highly offset relative to the sliding axis (Z). The invention is characterised in that the landing gear (10) comprises a linking structure (100) essentially consisting of two panels (101, 102) connecting two axially offset points of the strut assembly (12) to a common axle structure (103) extending along the strut assembly pivot axis (X). When the landing gear is in down position, the panels (101, 102) are perpendicular to each other, the upper panel (101) being linked to the strut assembly (12) by a high tie bar (105) which is torsionally rigid, while the lower panel (102) is linked to the strut assembly (12) by a low tie bar (106) which torsionally flexible, so as to allow skewness of the strut assembly (12) for turning manoeuvres of the aircraft on the ground.
Abstract:
Die Erfindung betrifft eine Strebe für das Fahrwerk und vorzugsweise das Bugfahrwerk eines Flugzeugs, die ein Y-förmig verzweigtes Gerüst (1) umfasst, wobei das Y-förmige Gerüst mehrteilig gefertigt ist und wenigstens zwei Balken (5a, 5b) umfasst, wobei ein erster Balken (5a) den ersten Ast des Gerüsts und ein zweiter Balken (5b) den zweiten Ast des Gerüsts (1) bildet und wobei beide Balken (5a, 5b) teilweise oder vollständig aus einem Faserverbundwerkstoff bestehen.
Abstract:
A fuselage for an airplane including a frame comprising an upper truss and a lower truss extending from a front end of the fuselage towards the rear end of the fuselage, wherein the lower truss comprises one or more forward box beams, a plurality of support rings attached to the upper truss and lower truss, a front bulkhead connected to a first end of the upper truss and lower truss, a main bulkhead connected to the upper truss and lower truss, a pressure vessel adapted to fit within the frame between the front bulkhead and main bulkhead, and a skin adapted to fit over the frame.
