International Classification:

G08B 23/00

US Classification:

340960, 340945

Abstract:

A tip alarm system for an aircraft having a nose landing gear (NLG) includes a sensor having first and second parts respectively disposed on first and second portions of the NLG that are respectively fixed to the aircraft and moveable relative to the fixed portion and operable to detect the position of the first and second portions relative to each other and to produce a tip alarm signal when the first and second NLG portions are disposed at a selected position relative to each other corresponding to an imminent aircraft tipping condition and thereby prevent the aircraft from tipping back onto the ground due to improper loading of the aircraft.

International Classification:

G01G 314
G01L 122

US Classification:

177211

Abstract:

A load cell adapted to be positioned between a foundation and each of several support members for a storage vessel. The load cell includes a circular flex plate having a pair of concentric cylindrical members of different diameters secured to opposite surfaces. A mounting pad adapted to be fastened to the foundation is secured to one of the cylindrical members. A mounting plate is secured to the other cylindrical member. The mounting plate has either a single threaded bore or a threaded stud positioned at the common axis of the cylindrical members for securing the mounting plate to a vessel support member. A strain sensor mounted on the flex plate measures the load-induced deflection of the flex plate.

Inventors:

Farid Piroozmandi - Bothell WA

Assignee:

Kistler-Morse Corporation - Bothell WA

International Classification:

G01G 900
G01G 1952
G01G 1902

US Classification:

177 1

Abstract:

A load measuring system specially adapted for installation on the support legs of existing storage vessels. The load measuring system includes an attachment plate that is fastened to each support leg of the vessel, a support plate that is mounted on anchor bolts projecting upwardly from the supporting surface, and a load cell positioned between the attachment plate and the support plate. The support plate is supported by nuts threaded on respective anchor bolts. The nuts are rotated to raise the lower ends of the support legs above the supporting surface, thereby transferring the portion of the vessel's weight carried by the support leg to the load measuring system. The space between the support plate and the supporting surface is then filled with a supporting material such as concrete.

International Classification:

B64C 25/30
B64C 25/14
B64D 29/06
B64D 27/18

Abstract:

Described are systems and methods for a nacelle auxiliary landing gear to be utilized as an alternative landing gear in the event of main landing gear non-deployment. The systems described herein include a nacelle auxiliary landing gear that includes a nacelle auxiliary landing gear strut and a nacelle auxiliary landing gear wheel, coupled to the nacelle auxiliary landing gear strut, wherein at least a first portion of the nacelle auxiliary landing gear wheel is configured to be disposed outside of a nacelle of an aircraft propulsor. The nacelle auxiliary landing gear strut is coupled to a core engine. Techniques for use of the nacelle auxiliary landing gear are also described herein.

Inventors:

- Chicago IL, US
Farid Piroozmandi - Kirkland WA, US

International Classification:

B64D 45/00
B64C 25/34
B64C 25/60

Abstract:

There is provided an aircraft tipping alarm system having a nose landing gear (NLG) shock strut containing hydraulic fluid and having an aperture. The system further has an elongated pressure chamber assembly configured to engage to the aperture. The elongated pressure chamber assembly has an elongated pressure chamber containing hydraulic fluid and having a pressure sensor device, a first check valve configured to restrict hydraulic fluid flow only into the NLG shock strut, a second check valve configured to restrict hydraulic fluid flow only into the elongated pressure chamber, and a reduced diameter breakable neck section. A potential aircraft tipping back position is indicated when a reduction of pressure of the hydraulic fluid in the NLG shock strut, sensed via the pressure sensor device, is greater than or equal to a pressure reduction threshold.
