US Patent:

6651931, Nov 25, 2003

Filed:

Sep 4, 2002

Appl. No.:

10/236748

Inventors:

Stephen J. Fox - Everett WA
Mark N. Simpson - Seattle WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

B64C 2510

US Classification:

244104R

Abstract:

Aircraft landing gear assemblies having multiple deployed static positions. In one embodiment, a landing gear assembly usable with a wing includes a wheel truck and a strut having a first strut end and a second strut end. The first strut end is configured to be pivotally connected to the wing, and the second strut end is configured to be pivotally connected to the wheel truck. In one aspect of this embodiment, the strut is configured to be connected to a first brace extending between the strut and the wing for positioning the wheel truck in a first deployed static position. In another aspect of this embodiment, the strut is further configured to be connected to a second brace extending between the strut and the wing for positioning the wheel truck in a second deployed static position different than the first deployed static position.

International Classification:

B64C 2516

US Classification:

244103R, 244 53 B, 244121

Abstract:

Apparatuses and methods for preventing foreign object damage (FOD) to aircraft engines are disclosed. In one embodiment, a deployable blocker is coupled to a wing portion and/or a fuselage portion of the aircraft and is configured to prevent debris from travelling on a direct trajectory from a landing gear wheel to an engine air inlet. In other embodiments, the blocker can prevent debris from bouncing off the wing lower surface into the engine inlet, or sticking to the wing lower surface and falling into the engine inlet. The deployable blocker can cover at least a portion of the landing gear when the landing gear is retracted and the blocker assembly stowed. In another embodiment, the blocker can be mounted to the landing gear.

Appl. No.:

7/320314

Inventors:

Patrick L. Anderson - Bellevue WA
Dennis P. Sarr - Kent WA
Mark B. Simpson - Everett WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

G01R 2726

US Classification:

324687

Abstract:

A probe (20) that inspects a countersunk hole (21) in a conductive body, such as an aircraft part (22), is provided. A plurality of nested cylinders form an electrode cartridge (54) with a countersink portion (74) having a frustoconical shape and a hole portion (76) having a cylindrical shape. A plurality of lower hole electrode strips (72) are mounted on a lower hole cylinder (110) and a plurality of upper hole electrode strips (70) are mounted on an upper hole cylinder (116). A plurality of lower countersink electrode strips (68) are coupled to a lower countersink cylinder (124) and a plurality of upper countersink electrode strips (66) are coupled to an upper countersink cylinder (132). A dielectric layer (64) covers a plurality of measuring electrode tips (67, 69, 71 and 73) and an outer surface (150) of the hole and countersink portions (76 and 74). A grounding electrode (158) is mounted on the upper hole cylinder ( 116).

G01B 11/14
G06K 9/00
B64C 25/60

Abstract:

Methods and systems are provided that facilitate the maintenance of levered landing gears by monitoring the condition of the stop pads of such landing gears. One embodiment provides for calibrating a sensor for measuring a condition of a stop joint formed by a first stop pad and a second stop pad of a levered landing gear against a nominal condition of at least one of the first stop pad and the second stop pad; monitoring, by the sensor, a current condition of the at least one of the first stop pad and the second stop pad from the nominal condition; determining whether a non-conformance from the nominal condition of the at least one of the first stop pad and the second stop pad has been detected by the sensor for the current condition; and in response to determining that the non-conformance has been detected, generating an alert.
