Filed:

Aug 6, 1999

Appl. No.:

9/369899

Inventors:

Gary W. Hall - Fort Worth TX
Michael Homan - Roanoke TX
Ron Bell - Grapevine TX

Assignee:

Bell Helicopter Textron Inc. - Fort Worth TX

International Classification:

G08G 504

US Classification:

701 16

Abstract:

A method and system for creating a precision approach for an aircraft to a position on the ground from a location above the ground is disclosed. The system comprises a display unit onboard the aircraft that displays a digital moving map, a database onboard the aircraft that contains digital terrain elevation data and obstacle data, a global positioning receiver that identifies the in flight position of the aircraft and an input device use to select the position on the ground displayed on the digital moving map. A processor that is also onboard the aircraft is communicably linked to the display unit, the database and the global positioning receiver. The processor generates the digital moving map on the display unit from the digital terrain elevation data and obstacle data and creates an approach derived from global positioning system data for the aircraft to the position on the ground selected on the digital moving map based upon the in flight position of the aircraft.

International Classification:

F16D 1/10

Abstract:

A torque-transfer component has splines configured for engaging a corresponding feature of another component, at least a portion of each spline being hardened before a friction-reducing surface coating is applied to the splines. The splines are preferably hardened by nitriding, carburizing, induction hardening, or laser hardening, and the friction-reducing coating preferably comprises diamond-like carbon or tungsten carbide. The coating can be applied using, for example, physical vapor deposition, chemical vapor deposition, chemically assisted physical vapor deposition, autocatalytic electroless deposition, electroplating, or an oxygen fuel gun.

International Classification:

B64C 27/59

US Classification:

244 992, 29428

Abstract:

In accordance with one embodiment of the present disclosure, a trunnion includes a first portion and a second portion. The first portion is capable of coupling directly to a drive tube of an aircraft, wherein the drive tube is capable of rotating around a first axis. The second portion is capable of coupling to a swash plate of the aircraft, wherein the swash plate is capable of causing the pitch of at least one of a plurality of aircraft blades to change.
