Patent number: 9225220Abstract: An permanent magnet alternator stator assembly for an integrated air turbine starter and permanent magnet alternator assembly has a permanent magnet alternator stator winding assembly attached to a mounting structure. A quick electrical connector electrically connects to the stator winding assembly and is attached to the mounting structure. The mounting structure includes an alignment aperture for removably attaching the permanent magnet alternator winding assembly to an air turbine starter. An integrated air turbine starter and permanent magnet alternator assembly and accessory gearbox assembly are also described.Type: GrantFiled: July 2, 2013Date of Patent: December 29, 2015Assignee: Hamilton Sundstrand CorporationInventors: Michael R. Blewett, Jeff A. Brown, Jeffrey A. Stadler

Patent number: 9194295Abstract: A mechanical system has a component to be lubricated that requires greater lubrication at lower speed conditions than would be required at higher speed conditions. A lubricant tower is biased to a position allowing a greater flow of lubrication to the component at lower speed conditions, then moved to a position at higher speed conditions where there is a lesser flow of lubrication.Type: GrantFiled: November 26, 2012Date of Patent: November 24, 2015Assignee: Hamilton Sundstrand CorporationInventors: Matthew Slayter, James Vandung Nguyen, Jeffrey A. Stadler, Timothy A. Johnson

Publication number: 20140250914Abstract: A starter motor has a housing. The housing receives the starter motor and a plurality of locations to receive lubricant. The lubricant supply system shares a lubricant source with a main gas turbine engine to be started by the starter motor. The lubricant supply system has a shutoff valve. The shutoff valve is opened when starter motor is being driven to start a main gas turbine engine. The shutoff valve is generally closed once the main gas turbine engine is started.Type: ApplicationFiled: March 11, 2013Publication date: September 11, 2014Applicant: Hamilton Sundstrand CorporationInventors: Matthew Slayter, Jeffrey M.

Patent number: 8678747Abstract: A brake assembly (44) for an air turbine starter (10) includes a brake cylinder (46) located in the air turbine starter (10). A brake piston (48) is located at least partially within the brake cylinder (46) and slidable therein. A biasing member (50) biases the brake piston (48) toward a turbine wheel (12) of the air turbine starter (10) applying a braking force to the turbine wheel (12) and defining a piston chamber (58) between the turbine wheel (12) and the brake piston (48). A through opening (56) in the brake piston (48) into the piston chamber (58) is configured such that a flow of fluid through the through opening (56) into the piston chamber (58) applies a force to the brake piston (48) sufficient to overcome the bias thereby allowing rotation of the turbine wheel (12).Type: GrantFiled: February 4, 2010Date of Patent: March 25, 2014Assignee: Hamilton Sundstrand CorporationInventors: Weishun Ni, Jeffrey A. Stadler, Jody A. Peterson

Patent number: 4965477Abstract: An integrated drive generator (40) for generating constant frequency alternating current which is driven by a drive shaft (12) at variable rotational speeds includes an alternating current generator (23) having a rotor (37) mounted on a first shaft (42), which is driven by an output of a constant speed drive (14) at a fixed rotational velocity, the constant speed drive also driving a second shaft (44) at a fixed rotational velocity; an exciter (20) having a rotor (32) mounted on the first shaft, electrically coupled to a field winding of the generator, for supplying electrical power to the field winding of hte alternating current generator; and a permanent magnet generator (18) having a rotor (24) mounted on the second shaft, electrically coupled to the exciter, for supplying electrical power to a field winding of the exciter. Using the second shaft reduces weight, as well as length.Type: GrantFiled: March 17, 1989Date of Patent: October 23, 1990Assignee: Sundstrand CorporationInventors: Jeffrey A. Stadler, Wayne A. Flygare
