Patent number: 7665694Abstract: An inlet door assembly and method for reducing noise from an auxiliary power unit (APU) contained within an aircraft housing is provided. The inlet assembly includes an inlet duct, an actuator, and a door. The inlet duct is configured to extend from the auxiliary power unit to the aircraft housing and has a sidewall that defines a flow passage through which APU noise propagates. The actuator is disposed at least partially within the inlet duct. The door coupled to the actuator. The actuator is also configured to selectively rotate the door between at least a first position, in which at least a portion of the door deflects APU noise in a first direction, and a second position, in which at least a portion of the door deflects the APU noise in a second direction.Type: GrantFiled: March 27, 2007Date of Patent: February 23, 2010Assignee: Honeywell International Inc.Inventors: Jeffrey M. Hein, Nicholas A. Williams, Yogendra Y. Sheoran, Cecilia S. Lam, Ora Morency Cowans, Benjamen Kurt Higuera, Andrew Stephen Peduchi, Ravisha Pramod Sellahewa, Daniel Brown

Patent number: 7600713Abstract: A pre-hung air inlet door assembly comprises an inlet door, a door box frame, and an actuation system. The door box frame is fastened to the support structure of an aircraft. The inlet door is operationally connected to the actuation system. The entire pre-hung air inlet door assembly can be pre-assembled for quick installation into an aircraft. Pre-assembly eliminates trimming operations and rigging and misalignment issues. The pivot shafts and bearing housings of the pre-hung air inlet door assembly can be accessed from outside the aircraft when repairs and/or replacement components are needed.Type: GrantFiled: March 4, 2005Date of Patent: October 13, 2009Assignee: Honeywell International Inc.Inventors: Jeffrey M. Hein, Nicholas A. Williams

Patent number: 7448656Abstract: A dual action structural latch (10) is provided for securing hinged access doors to a frame. The latch (10) comprises a latching member (58) secured to the frame and defining a first aperture (60). A hook member (24) engages the latching member (58) to resist a tensile force when the latch (10) is in a closed position, and disengages the latching member (58) when the latch (10) is in the open position. A shear pin (36) extends so as to engage within the first aperture (60) to resist a shear force when the latch (10) is in the closed position and to disengage the first aperture (60) when the latch (10) is in the open position.Type: GrantFiled: April 30, 2007Date of Patent: November 11, 2008Assignee: Honeywell International Inc.Inventors: Jeffrey M. Hein, Nicholas A. Williams

Patent number: 5431015Abstract: A closed loop fully self-contained actuation system for converting a mechanical input motion into a mechanical output motion, which actuates a device such as a flight control surface on an aircraft, comprises an input actuator including a first fluid pressurizing means responsive to the mechanical input motion, and an output actuator including a second fluid pressurizing means, as well as a flexible fluid line extending between the first and second fluid pressurizing means to provide fluid communication therebetween. The second fluid pressurizing means is responsive to fluid flow through the fluid line, thereby initialing the output motion. The system is advantageous because it requires no hydraulic pumps, no accumulators, no reservoirs, and no dynamic seals or mechanical joints, permitting great reliability. The actuation system may be easily folded in conjunction with the apparatus on which it is employed, for compact storage.Type: GrantFiled: September 2, 1993Date of Patent: July 11, 1995Assignee: McDonnell Douglas HelicopterInventors: Jeffrey M.
