US Patent:

7104143, Sep 12, 2006

Filed:

Aug 11, 2005

Appl. No.:

11/201387

Inventors:

Arthur Gregory Powell - Westminster CA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

G01F 1/28

US Classification:

7386174

Abstract:

An oscillating vane actuator for active control of fluid flow over a surface includes a pivoted vane surrounded by a wedge-shaped chamber, and first and second conduits with openings adjacent the surface. The actuator also includes a rotating shaft with a connecting rod to actuate the vane in a oscillatory manner. As the vane travels in one direction, fluid is forced out from the chamber through the first conduit and opening into the fluid stream adjacent the surface, while fluid is simultaneously drawn in through the second opening and conduit into the opposite side of the chamber. Similarly, when the vane travels in the opposite direction, fluid is forced out through the second conduit and opening into the fluid stream adjacent the surface, while fluid is simultaneously drawn in through the first opening and conduit.

Appl. No.:

11/871939

Inventors:

Arthur G. Powell - Huntington Beach CA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B64D 39/00

US Classification:

244135A

Abstract:

In-flight fuel transfer from one aircraft to another aircraft or aerial refueling can extend the flight duration of a receiver aircraft and thereby increase its operational range and/or effectiveness by enabling it to fly farther or for longer duration without returning to the ground. Improved aerial fuel transfer is disclosed in connection with a method and system for in flight transfers of fuel from one aircraft to another. Enhanced fuel transfer operations including boom control are disclosed.

Appl. No.:

12/356018

Inventors:

Arthur G. Powell - Huntington Beach CA, US
Paul M. Vijgen - Everett WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B64C 21/06

US Classification:

244208, 244204, 244130, 244207

Abstract:

A purging system for a laminar flow control system comprises an air scoop and a diffuser fluidly connected thereto. The air scoop is disposable into an external flow of an external atmosphere. The diffuser is configured to fluidly connect the air scoop to a suction cavity of the laminar flow control system wherein the suction cavity may be disposed adjacent a porous skin of an airfoil such as adjacent a leading edge of the airfoil. The laminar flow control system may be configured to suction boundary layer flow passing over the porous skin by drawing a portion of the boundary layer flow through a plurality of pores formed in the porous skin. The diffuser ducts high pressure flow captured by the air scoop to the suction cavity for discharge through the pores to reduce the potential of blockage thereof.

Abstract:

A rotor blade including a root attachable to a rotor hub. The blade includes a tip and one or more channels aligned within the blade generally between the root and the tip. Each channel has a sealed first end and a second end vented to outside the blade. The channel(s) are vented to one or more exterior surfaces of the blade through one or more apertures in the exterior surface(s).
