Patent number: 10648428Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, an actuator, and a hydraulic assist mechanism. The actuator is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The hydraulic assist mechanism is coupled to the transcowl and is configured to react reverse thrust loads on the transcowl at least when the transcowl is translating between the stowed position and the deployed position.Type: GrantFiled: October 11, 2016Date of Patent: May 12, 2020Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Steve Abel, James Wawrzynek, Patrick Hinke, Ron Vaughan

Patent number: 10443541Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, and an actuator. The transcowl is mounted on the support structure and is axially translatable between a stowed position and a deployed position. The actuator is coupled to the transcowl and the support structure, and is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The actuator includes an actuator housing, a screw, a nut, a rod end, and a tension rod. The tension rod is engaged by the nut when the transcowl is in the deployed position and is engaged by the rod end when the transcowl is in the stowed position, whereby actuator loads, in both the deployed and stowed positions, are transmitted through the tension rod to the support structure.Type: GrantFiled: December 20, 2016Date of Patent: October 15, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Kevin K Chakkera, Daniel C Birchak, Donald Jeffrey Christensen, James Wawrzynek

Patent number: 10393066Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, a door, a main actuator, and an assist actuator. The transcowl is mounted on the support structure and is axially translatable between a stowed position and a deployed position. The door is pivotally coupled to the support structure and is rotatable between at least a first position and a second position when the transcowl translates between the stowed position and the deployed position, respectively. The main actuator is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The assist actuator is coupled to the door, and is configured to supply an actuation assist force to the door and, upon rotation of the door to an intermediate position between the first position and the second position, to commence load sharing with the main actuator.Type: GrantFiled: February 3, 2017Date of Patent: August 27, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: James Wawrzynek, Steve Abel, Kevin K Chakkera

Patent number: 10371091Abstract: A thrust reverser control system includes a plurality of actuators, an electric motor, an electric brake, and a control. Each actuator is responsive to an actuator input torque to move between a stowed position and a deployed position. The electric motor is coupled to each of the actuators and is configured, upon being energized from a voltage source having a supply voltage magnitude, to supply the actuator input torque to the actuators and further configured to selectively generate regenerative current. The electric brake is coupled to be selectively supplied with the regenerative current and is configured, upon being supplied with the regenerative current, to supply a braking torque that slows movement of the actuators. The control is coupled to the electric brake and is configured, upon the supply voltage magnitude exceeding a predetermined value, to cause the regenerative current to be supplied to the electric brake.Type: GrantFiled: January 9, 2017Date of Patent: August 6, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Steve Abel, James Wawrzynek, Patrick Hinke

Publication number: 20180058372Abstract: A thrust reverser system for a gas turbine engine includes a support structure, a transcowl, an actuator, and a retractable cable. The support structure is configured to be mounted to the turbine engine. The transcowl is mounted on the support structure and is axially translatable, relative to the support structure, between a stowed position and a deployed position. The actuator is configured to supply an actuation force to the transcowl to thereby move the transcowl between the stowed and deployed positions. The retractable cable is coupled to the transcowl and the support structure, and is configured to react reverse thrust loads on the transcowl at least when the transcowl is in the deployed position, to thereby at least reduce thrust loading on the actuator.Type: ApplicationFiled: November 22, 2016Publication date: March 1, 2018Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Donald Jeffrey Christensen, Kevin K. Chakkera, Daniel C. Birchak, James Wawrzynek
