Patent number: 10294965Abstract: A blisk fan is provided for a turbine engine propulsion system. The blisk fan includes a hub configured to rotate about a rotational axis at a maximum rotational speed, and a plurality of blades extending radially outward from the hub to define a fan leading edge tip diameter. Each of the blades has a first vibratory mode at a natural frequency, which is greater than a first fan order and less than a second fan order at the maximum rotational speed. The compression system preferably has a balance factor of the compression system between 1.9 and 3.2.Type: GrantFiled: May 25, 2016Date of Patent: May 21, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Nick Nolcheff, Michael LaMar Trego, John Repp, James Kroeger

Publication number: 20180030900Abstract: An air turbine starter (ATS) includes a support structure and a turbine. The ATS additionally includes a gear train that is configured for receiving torque input from the turbine. The gears include an integrated input gear. The ATS further includes an output member. The output member is operably coupled to the gear train and a main engine input member. The output member is configured to transfer torque from the gear train to the main engine input member. Additionally, the ATS includes a motor system that is supported by the support structure. The motor system includes a motor and a motor output gear. The motor output gear is configured to engage the integrated input gear for selectively delivering motor torque from the motor to the integrated input gear such that the motor torque transfers to the main engine input member to selectively dry motor the main engine at a predetermined speed.Type: ApplicationFiled: August 1, 2016Publication date: February 1, 2018Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Dave Mathis, Mike Bush, Jason G.

Patent number: 8702377Abstract: A gas turbine engine rotor tip clearance and shaft dynamics system and method are provided. The system includes a gas turbine engine that is disposed within an engine case and includes a rotor. A rotor bearing assembly disposed within the engine case rotationally mounts the gas turbine engine rotor. Vibration isolators mounted on the engine case are coupled to the rotor bearing assembly, and are configured to provide linear and independently tunable stiffness and damping. A method includes determining the location of a gas turbine engine rotor rotational axis, disposing the gas turbine engine rotor in an engine case at the rotational axis location, mounting a plurality of vibration isolators that include a plurality of adjustment devices on the engine case, coupling each vibration isolator to the gas turbine engine rotor, and locking the gas turbine engine rotor at the rotational axis location using the plurality of adjustment devices.Type: GrantFiled: June 23, 2010Date of Patent: April 22, 2014Assignee: Honeywell International Inc.Inventors: Brian Cottrell, George Jerzy Zalewski, James Kroeger

Publication number: 20120055039Abstract: An appliance for drying or warming associated laundry items includes a housing having a wall forming a stationary cavity dimensioned to receive the associated laundry items. At least one article support member is preferably contained within the cavity. A heater increases a temperature of associated air within the cavity and a fan circulates the heated air within the cavity. A vent is dimensioned to allow air to exit the housing cavity, and a controller regulates circulation of the associated heated air within the cavity.Type: ApplicationFiled: September 8, 2010Publication date: March 8, 2012Inventors: Eric K.

Patent number: 8070448Abstract: Spacers and turbines are provided. In an embodiment, and by way of example only, a spacer includes a strip, a first retention flange, and a second retention flange. The strip has a first edge, a second edge, and an impingement surface, and the impingement surface extends axially along the strip between the first edge and the second edge and is substantially flat. The first retention flange is recessed relative to the impingement surface and extends away from the first edge of the strip. The second retention flange is recessed relative to the impingement surface and extends away from the second edge of the strip.Type: GrantFiled: October 30, 2008Date of Patent: December 6, 2011Assignee: Honeywell International Inc.Inventors: Mark C. Morris, Milton Ortiz, David Waldman, James Kroeger

Patent number: 7750498Abstract: An adaptive power management system includes a number of load devices, including a burst load device operable with a time-varying load having a controllable duty cycle. A shared power source supplies power to the load devices. The system adaptively determines a power allocation for the burst load device based on operational requirements of the load devices, and the maximum power supplied to the burst load device is limited to a selected power level based on the determined power allocation. A power storage module stores power supplied by the shared power source and supplies sufficient power to permit the burst load device to operate during burst periods with a peak power that exceeds the average power supplied to the power storage module. The duty cycle of the burst periods of the burst load device is controlled to maintain the power stored by the power storage module above a desired level.Type: GrantFiled: September 20, 2007Date of Patent: July 6, 2010Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Bruce A. Wight, James Kroeger

Patent number: 4723613Abstract: An electronic balance having a stored setup routine for defining scale operating parameters. An indicating device, which may be interchangeably connected to a plurality of weighing platforms, is responsive to an identifying connector to select from a memory operating parameters related to an operational characteristic of the weighing platform during the setup routine. A plurality of multi-function manually actuated buttons permit user selection of operating parameters during the setup routine. A sealable switch is used to restrict access to the setup routine. The balance operates in weighing or parts counting modes and can display weight in the parts counting mode. The balance can also provide a user with an indication of whether a dead-load or span adjustment is necessary.Type: GrantFiled: May 21, 1986Date of Patent: February 9, 1988Assignee: Ohaus Scale CorporationInventors: Daniel R.
