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.

Inventors:

- Chicago IL, US
Michael John McNulty - Scottsdale AZ, US
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.
