International Classification:

G06F 11/30

US Classification:

702183, 244213

Abstract:

A method for detecting freewheeling skew failures in the wing flaps of an aircraft includes measuring the outputs of flap skew sensors when the aircraft is in flight (IF) and the flaps are extended to a selected position, and when the aircraft is next on the ground (OG) and the flaps are extended to the selected position. The respective differences between the IF and OG outputs of symmetrical pairs of the flap skew sensors are computed, and then the respective difference between the computed IF output difference and the computed OG output difference of each symmetrical pair of the sensors is computed. The computed IF and OG difference of each symmetrical pair of the sensors is then compared with each of predetermined maximum and minimum threshold value to determine whether a freewheeling skew failure exists in any of the flaps of the aircraft.

US Classification:

3406861, 340945, 3406862, 244194, 244203, 244213

Abstract:

An apparatus comprises a sensor system, a flexible line, and a sensor. The sensor system is capable of detecting skew in at least some of a plurality of control surfaces for a vehicle. The flexible line extends across a number of interfaces for a portion of the plurality of control surfaces. The sensor is connected to the flexible line and is capable of detecting the skew in the portion of the plurality of control surfaces in response to a selected amount of movement of the flexible line.

International Classification:

B64C 358
B64C 900
B64C 350
B64C 1334
B64C 1300

US Classification:

244213

Abstract:

Referring to FIG. 2, disclosed is an aircraft compound no-back/offset gearbox (2) with an integral load proportional safety (no-back) brake (50). The four gears are all 16 diametral pitch, involute external spur gears with 20 degree standard pressure angles. The two gear stages are interconnected with a mechanical fuse or shearout (40) designed to fail under excess shear loads and protect components downstream of the input shaft (10) from excess torque in the event of a system jam. The shearout (40) is essentially a quill shaft with external splines at both ends and an hourglass-shaped shear neckdown in the middle. The purpose of the no-back brake (50) is to prevent air loads from causing slat movement in the event of a torque tube disconnect. Referring to Figure, the no-back consists of a set of ball ramp (22) and brake plate components connected to the gearbox's output shaft. The ball ramp device converts part of the back driving torque into the axial force required to clamp the brake stack components (30) and restrain the output shaft.

International Classification:

B64C 3/56

Abstract:

An apparatus and method of a wing fold system may include a latch assembly rotating an unfixed portion of a wing, with respect to a fixed portion of the wing, between a flight position of the wing and a folded position of the wing. A first portion of the wing may hold a rotating portion of the latch assembly. A second portion of the wing may hold a secured portion of the latch assembly. The rotating portion of the latch assembly may rotate between an open position and a closed position. A slot in the rotating portion may receive the secured portion of the latch assembly. A securing portion of the rotating portion may secure a secured portion of the latch assembly. The latch assembly may prevent rotation of the second portion when the wing may be in the flight position.
