AERODYNAMIC NOISE REDUCING THIN-SKIN LANDING GEAR STRUCTURES AND MANUFACTURING TECHNIQUES

A thin-skin support member is provided. The thin-skin support member may include a semi-circular edge and a flat edge that define a hollow cavity. A cylindrical cavity may be adjacent the hollow cavity and at least partially defined by the semi-circular edge. The cylindrical cavity may be configured to retain a strut assembly. A mounting interface may be coupled to the semi-circular edge and the flat edge. A torsion interface may be disposed adjacent the cylindrical cavity and configured to receive a torsion link. The thin-skin support member may be made using additive manufacturing and thus may have a grain structure grown in the direction of material being added.

SYSTEMS AND METHODS FOR DETECTION OF DRAGGING BRAKE
20170355473 · 2017-12-14 · ·

A landing gear assembly may include a first wheel and a second wheel, a first wheel sensor coupled to the first wheel and a second wheel sensor coupled to the second wheel, and a controller coupled to the first wheel sensor and the second wheel sensor. A tangible, non-transitory memory may have instructions for detecting a dragging brake. The controller may perform operations including receiving data from the first wheel sensor and the second wheel sensor, calculating a wheel speed characteristic for each of the first wheel and the second wheel based on the data, identifying a lowest value for the wheel speed characteristic, determining a moving average for the wheel speed characteristic, comparing the lowest value to the moving average, and whether the lowest value for the wheel speed characteristic indicates a dragging brake.

Active semi-levered landing gear
09840322 · 2017-12-12 · ·

An active oleo system for an aircraft semi-levered landing gear system disclosed herein includes a main strut, an auxiliary strut, bogie beam, and a pressure boost mechanism. During a takeoff roll phase, the pressure boost mechanism may increase the pressure in the main strut, forcing the main strut piston to the fully extended length. Thru the action of main strut, auxiliary strut, and bogie beam this may increase the height of the aircraft above ground, providing for a larger achievable rotation angle of the aircraft.
