Patent number: 9612412Abstract: A beam combining device comprising at least one beam splitter and phase adjustment circuitry. The at least one beam splitter comprises a semi-reflective surface, first and second inputs, and first and second outputs operatively connected to receive first and second light beams. The semi-reflective surface has first and second sides positioned such that light entering from one input is partially reflected through one output and partially transmitted through another output. The phase adjustment circuitry adjusts the relative phases of the first and second light beams so that light transmitted through the semi reflective surface from one input may be adjusted to have a phase which can cancels or constructively adds to light reflected from another input. Light having a combined power of the light beams, or a fraction thereof, may be selectively emitted through a selective output depending upon the adjustment of phases. Also, a method of operation is claimed.Type: GrantFiled: October 31, 2013Date of Patent: April 4, 2017Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Jeffrey Owen White

Patent number: 9499253Abstract: Apparatus and methods are disclosed for designing and manufacturing a composite structure, such as a composite rotor blade spar or composite rotor blade. A first mold may define a first mold surface and a second mold may include a rigid layer and a heated layer secured to the rigid layer and defining a second mold surface. A plurality of heating elements embedded in the second mold may be activated according to different temperature progressions to cure portions of the uncured composite rotor blade positioned coextensive therewith. In some embodiments, the second mold defines a root portion and first and second branch portions. A shear web may be placed between the branch portions during curing. The blade spar may define a complete airfoil contour or have fairings secured thereto having lines extending therethrough to a tip jet. A tip jet mounting structure and blade root attachment apparatus are also disclosed.Type: GrantFiled: November 14, 2011Date of Patent: November 22, 2016Inventor: Robert Owen White

Patent number: 9079659Abstract: A fairing system may be assembled about a rotor of a rotorcraft to present an aerodynamically quasi-static region that rotates in an airstream, as well as certain extensions that sweep through the airstream as the rotor hub passes through the air. A spherical interface between the extensions on the rotor hub fairing and the base or root portion of each blade fairing provides three degrees of freedom permitting lead-lag, flapping, and blade pitch pivoting in the blade, while still maintaining an aerodynamic profile that will minimize drag.Type: GrantFiled: March 22, 2012Date of Patent: July 14, 2015Assignee: General Aeronautics Corporation, Inc.Inventors: Jacob J. van der Westhuizen, Robert Owen White
