Publication number: 20090072082Abstract: A propulsion system for an airship or hybrid aircraft includes a propeller and a pivot mechanism connected to the propeller. The pivot mechanism enables the propeller to pivot around a first pivot axis between a maneuver thruster position and an emergency ballonet fill position. Under normal conditions, when the propulsion system is disposed in the maneuver thruster position, the pivot mechanism also enables the propeller to pivot around a second pivot axis to control the attitude and thrust of the vehicle. However, in an emergency descent situation, the propeller may be rotated to the emergency ballonet fill position.Type: ApplicationFiled: April 11, 2007Publication date: March 19, 2009Applicant: Hamilton Sundstrand CorporationInventor: David V.

Publication number: 20090068012Abstract: A wind turbine system includes a shaft, a rotor for driving the shaft, and a first fluidic teeter control assembly. The rotor includes a first blade engaged to the shaft by a hub, and has a degree of freedom to pivot relative to the shaft. A first teeter angle is defined between an instantaneous position of the first blade and a time-averaged plane of rotation of the first blade. The first fluidic teeter control assembly is engaged between the rotor and the shaft for providing a first dynamic teeter restraining force as a function of the first teeter angle and a fluidic resistance. The first dynamic restraining force is relatively low when the first teeter angle is within a first teeter operation range, and the first dynamic restraining force is higher when the first teeter angle is outside that range.Type: ApplicationFiled: September 6, 2007Publication date: March 12, 2009Applicant: Hamilton Sundstrand CorporationInventor: Fabio P. Bertolotti

Publication number: 20090069998Abstract: An event-driven starter controller regulates the speed of a gas turbine engine based on detected events. The event-driven starter controller is used to supply motive force to the gas turbine engine, prior such that the gas turbine engine is able to ignite (i.e., achieve light-off). In particular, in response to engine speed reaching a defined threshold, the event-driven starter controller causes the speed of the starter motor to ramp or increase through a defined range of speeds suitable for engine light-off (i.e, light-off window). Upon reaching an upper threshold of the light-off window, the event-driven starter controller causes the speed of the starter motor to decrease through the range of speeds suitable for engine light-off. If at any time during the light-off window the event-driven starter controller detects a successful light-off condition, the event-driven starter controller causes the speed of the gas turbine engine to increase toward a second threshold.Type: ApplicationFiled: March 30, 2007Publication date: March 12, 2009Applicant: Hamilton Sundstrand CorporationInventors: Michael E. Mehrer, Peter J. Suttie, Alex Seguritan, Gilles E. Marion

Patent number: 7495353Abstract: The power system for an aircraft includes a gear box. Multiple generators are driven by the gear box and are arranged in a circumferentially spaced manner, in one example. Each generator includes a power interconnect block providing a receptacle that receives an electrical lead. The receptacle provides a metallic insert having a hole that receives a connector arranged at an end of the electrical lead. The connectors are inserted into the hole in a direction that is generally parallel with an axis of rotation of a shaft of the generator. An axial retainer is secured between the electrical connector and the power interconnect block to axially locate the connector within the power interconnect block. A spring washer is arranged at a base of the hole to exert an axial force on the connector biasing it against the axial retainer.Type: GrantFiled: August 1, 2006Date of Patent: February 24, 2009Assignee: Hamilton Sundstrand CorporationInventors: Scott Alan Christensen, Darin R.
