Publication number: 20110305554Abstract: A vaneless compressor containment design has an inner bolt circle with more than three fasteners situated in the vaneless space to cut up tri-hub pieces to smaller pieces prior to reaching an outer bolt circle and its associated flange. This containment design may allow a thinner radial wall thickness for the outermost flange as compared to the conventional design. The thinner radial wall thickness may reduce the weight of the compressor. This weight reduction may be achieved with little or no increase in the compressor space envelope.Type: ApplicationFiled: June 14, 2010Publication date: December 15, 2011Applicant: HONEYWELL INTERNATIONAL INC.Inventors: ROBERT P. CHEN, FRANK LIN, DAVID G. ELPERN

Patent number: 7871243Abstract: A containment system comprises at least one passage obstructer extending from a housing inlet cover through a diffuser passage and into a housing back cover. The passage obstructer includes a fastener portion, such as a bolt, and an obstructing portion extending from and integral to a shaft of the fastener portion. The diameter of the obstructing portion is less than the diameter of the shaft, allowing the obstructing portion to bend upon impact with a burst impeller fragment.Type: GrantFiled: June 5, 2007Date of Patent: January 18, 2011Assignee: Honeywell International Inc.Inventors: Robert P. Chen, Terry Morris, Deborah A. Osborne

Patent number: 7488111Abstract: A composite resilient mount for rolling element bearings, comprising a composite hoop portion, and including a plurality of circumferentially dispersed inner pads and outer pads defining a plurality of arcuate beam portions disposed circumferentially between adjacent pads. The hoop portion and the inner and outer pads, may comprise a circumferentially wound fiber, such as a carbon fiber, and a resin. The inner and outer pads may be rounded, feathered or otherwise configured to eliminate edges from the inner and outer pads, thereby preventing damage to adjacent components. A method for providing damping to a rolling element bearing is also disclosed.Type: GrantFiled: April 4, 2006Date of Patent: February 10, 2009Assignee: Honeywell International Inc.Inventors: Robert P.

Patent number: 7461443Abstract: An inner sleeve, having threads on each end, is formed on a motor or generator rotor. A pair of stub shafts are threadably attached to the inner sleeve at each end and a magnet is placed in between. The stub shafts are turned on the inner sleeve to bring them together, thereby creating an axial compressive force on the magnet. By keeping the magnet in a compressive state at all times, cracking of the magnet is prevented, thus keeping the rotor stable during use of the motor or generator. An outer sleeve is shrunk-fit around the magnet and stub shafts to provide a further radial force on the rotor. The magnet assembly of the present invention also enlarges the required radial shrink-fit tolerance of the outer sleeve on the magnet, thereby reducing costs conventionally required to match the outer sleeve to the magnet within close tolerances.Type: GrantFiled: April 27, 2006Date of Patent: December 9, 2008Assignee: Honeywell International, Inc.Inventors: Sam Shiao, Robert P. Chen

Patent number: 7432702Abstract: A circuit board damping assembly provides a damping node for a circuit board coupled in spaced relationship to another circuit board or chassis. The circuit board damping assembly includes a chassis or circuit board forming a base member; a circuit board coupled in spaced relationship to the base member; a first attachment member coupled to the base member; a second attachment member coupled to the circuit board; and a connector coupled between the first and second attachment members. The connector may be a wire coupled to the first and second attachment members.Type: GrantFiled: December 22, 2005Date of Patent: October 7, 2008Assignee: Honeywell International Inc.Inventors: Sam Shiao, Robert P. Chen

Patent number: 6789998Abstract: A system and method for reducing blade strain on the fan blades of an air cycle machine is proposed. The method involves a strut arrangement that is positioned in a cylindrical air passage upstream from the fan assembly. The strut arrangement includes at least three struts, wherein the at least three struts are separated by unequal degrees of separation along the circumference of the air passage. The strut arrangement effectively reduces the strain on the blades of the fan assembly.Type: GrantFiled: September 6, 2002Date of Patent: September 14, 2004Assignee: Honeywell International Inc.Inventors: Robert P. Chen, Sasha M. Ablitt, Ramesh C. Doshi

Patent number: 6481917Abstract: An apparatus for preventing movement of a wheel on a shaft comprises a nut concentrically disposed on the shaft. A spring is disposed on the shaft and is operatively adjacent to the nut such that the spring can be biased towards the wheel. A first clamping ring is concentrically disposed on the wheel, with the first clamping ring being operatively adjacent the spring. A second clamping ring is operatively adjacent to the side of the wheel that is opposite to the first clamping ring, and a raceway is disposed between the shaft and wheel.Type: GrantFiled: May 2, 2000Date of Patent: November 19, 2002Assignee: Honeywell International Inc.Inventors: Robert P.

Patent number: 6059532Abstract: A high aspect ratio, low solidity fan blade of an axial flow air cycle machine has a local tip center of gravity axis that has been shifted ahead of an elastic axis. The center of gravity axis can be shifted by clipping the tip of the blade at the trailing edge, by undercutting a rear portion of the pressure surface, or by sweeping forward leading and trailing edges of the blade by about five degrees (without clipping or undercutting the blade).Type: GrantFiled: May 20, 1998Date of Patent: May 9, 2000Assignee: AlliedSignal Inc.Inventors: Robert P.
