摘要:
Control link (600) for an aircraft (101, 201) comprising an impact-resistant structure with a redundant load path. The control link (600) has an inner structure (602) that is sized to carry the anticipated load of the flight control system and to meet all safety factors. The control link (600) also has an outer structure (601) that is sacrificial and configured to absorb impact damage during operation, thereby protecting the inner structure (602). The outer structure (601) is also designed to carry the anticipated load of the flight control system on its own, independent of the inner structure (602), and to meet all safety factors. If the outer structure (601) fails, the inner structure (602) allows for continued safe operation of the flight control system. The space or cavity (604) between the inner and outer structures (601,602) may be filled with a material, such as a closed-cell foam, to improve the impact resistance of the outer structure (601).

A ganged servo flight control system for an unmanned aerial vehicle is provided. The flight control system may include a swashplate having first, second, and third connection portions; a first control assembly connected to the first connection portion of the swashplate; a second control assembly connected to the second connection portion of the swashplate; and a third control assembly connected to the third connection portion of the swashplate. The first control assembly may include two or more servo-actuators connected to operate in cooperation with each other.
摘要:
La présente invention concerne un combinateur (1) de commandes de vol pour aéronef hybride, ledit combinateur (1) comportant un support (2) mobile en rotation autour d'un premier axe (A1), un plateau (5) lié audit support (2) par une première bielle de renvoi (3) et une seconde bielle (4). Lesdites bielles (3,4) sont liées audit support (2) et audit plateau (5) par des liaisons pivots d'axes parallèles formant ainsi un parallélogramme. Un premier levier (6) transmettant un premier ordre entraîne un déplacement de ladite première bielle de renvoi (3) et, par suite, dudit plateau (5). Un deuxième levier (7) transmettant un deuxième ordre est lié audit plateau (5). La rotation dudit support (2) et le déplacement dudit plateau (5) permet par l'intermédiaire dudit premier ordre de faire varier le gain appliqué audit deuxième ordre afin de commander de manière adaptative le pas des pales d'hélices propulsives dudit aéronef par l'intermédiaire d'un troisième levier (8) lié audit plateau (5).
摘要:
Rotor assembly (200) comprising a twist actuator (216) to drive a first rotation of a first shaft about a first axis, the twist actuator positioned at a center of rotation of the rotor assembly; and a first gear assembly to convert the first rotation into a plurality of second rotations of a plurality of second shafts, each of the second shafts to provide torque to a respective blade coupled to the rotor assembly (200).
