US Patent:

6889965, May 10, 2005

Filed:

Oct 10, 2001

Appl. No.:

09/974991

Inventors:

Robert T. Loftus - Gilbert AZ, US
Neal M. Muylaert - Apache Junction AZ, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

F16M001/00

US Classification:

267136, 416134 A

Abstract:

The invention provides a weight-reducing bearing assembly for rotary aircraft. An opposed tapered conical elastomeric flap bearing assembly for rotary aircraft includes an outer housing having an outer surface and an inner surface. The outer surface is configured to mechanically connect the bearing assembly to the attachment sections of the hub center body. The inner surface is configured to receive a pair of opposed taper conical bearing elements. An inboard bearing element and an outboard bearing element are located within the outer housing. The bearing elements are arranged in an opposed manner. An axial pre-load can be applied to the opposed bearing assembly wherein the resulting force couple bearing pre-load path is maintained entirely within the bearing assembly. Consequently, the weight of the main rotor hub is reduced increasing the efficiency of rotary flight.

Appl. No.:

10/847006

Inventors:

Robert T. Loftus - Gilbert AZ, US
Michael J. McNulty - Scottsdale AZ, US
Kevin D. Henthorn - Mesa AZ, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

F01D 5/00

US Classification:

416145, 416500

Abstract:

A system of adjustable balancing weights is provided for a helicopter main rotor blade. The trailing edge of the rotor blade is formed with a plurality of recesses that each receive an aerodynamically shaped weight to adjust and balance the weight of the rotor blade. A forward weight recess and a forward weight are also provided on the rotor blade adjacent the rotor blade leading edge. The lateral spacing between the weight adjacent the rotor blade leading edge and the weights adjacent the rotor blade trailing edge provides greater flexibility in balancing the mass of the rotor blade.

Robert Loftus - Gilbert AZ, US

International Classification:

B21D 22/16
B29C 70/32

Abstract:

A system to manufacture an object includes a headstock, a tailstock, and a mandrel having a first end coupled to the headstock and a second end coupled to the tailstock. The system also includes an actuator coupled to one or more of the headstock, the tailstock, or the mandrel, the actuator operable to apply a force to the one or more of the headstock, the tailstock, or the mandrel, to oppose deformation of the mandrel.
