Patent number: 9303971Abstract: High aspect ratio positioning systems are disclosed herein. A high aspect ratio positioning system can be packaged in a thin package that can eliminate some bulky components typically associated with positioning systems such as pancake motors or other motors, geared resolvers, gear trains, and the like. Thus, the high aspect ratio positioning system can be used in applications where volume is limited, without sacrificing accuracy.Type: GrantFiled: December 15, 2010Date of Patent: April 5, 2016Assignee: The Boeing CompanyInventors: Stephen T. Butscher, Robert J. Atmur, Angelo Truncale, Joseph E. Justin, Thomas C. Williams

Patent number: 6250589Abstract: An apparatus for rigidly interlocking a control stick and the rudder pedals of an aircraft is provided for protecting the control surfaces of the aircraft operated by the control stick and the rudder pedals against wind loads. The apparatus comprises a control stick clamp assembly rigidly connected to one end of a first lever arm and a rudder pedal retaining assembly rigidly connected to another end of the first lever arm. A second lever arm has one end connected to the rudder pedal retaining assembly. The second lever arm is moveable between a collapsed position and an extended position wherein the distal end of the second lever arm is engageable with a support surface such that the second lever arm is able to support the rudder pedal retaining assembly in engagement with each of the rudder pedals and thereby cause, upon the control stick clamp assembly being secured to the control stick, the first lever arm to support the control stick in a selected position.Type: GrantFiled: February 10, 2000Date of Patent: June 26, 2001Inventors: Richard T. Russ, Thomas C. Williams

Patent number: 5911391Abstract: A locking apparatus in combination with a locking pin and method for rigidly interlocking a control wheel and the rudder pedals of an aircraft is provided for securing the control surfaces of the aircraft operated by the control wheel and the rudder pedals in a stable position. The locking pin is adapted to be disposed through aligned locking pin receiving holes of the control column and the control panel collar and has a recess formed therein for lockingly receiving a portion of the control column. The locking apparatus includes a pair of control wheel retaining members rigidly connected to one end of a rod member for retainingly engaging the control wheel and a rudder pedal engaging bar rigidly connected to one end of another rod member. The rudder pedal engaging bar is positionable in a V-shaped notch of each of the rudder pedals so as to engage each of the rudder pedals and so as to secure the rudder pedal engaging bar on the rudder pedals.Type: GrantFiled: June 18, 1997Date of Patent: June 15, 1999Inventors: Richard T. Russ, Thomas C. Williams
