Patent number: 9267384Abstract: A flyweight for use in a ram air turbine has a body with a circumferentially enlarged portion extending between flat sides spaced by an angle of between 45 degrees and 150 degrees. A pivot point is defined by a bore at a circumferentially intermediate point in the body, and in a relatively thin inner portion. The relatively thin inner portion extends beyond the pivot point to an end that will be radially inward when the flyweight is mounted in a ram air turbine. A governor, a ram air turbine and a method are also described.Type: GrantFiled: March 2, 2012Date of Patent: February 23, 2016Assignee: Hamilton Sundstrand CorporationInventors: David G. Bannon, David L. Jacques

Publication number: 20120221157Abstract: An emergency power system is useable on an aircraft having a gas turbine engine with a low pressure spool and a high pressure spool. The emergency power system includes an emergency electrical generator coupled to the low pressure spool during an emergency for generating emergency electrical power and one or more additional electrical power sources. A plurality of electrical loads are electrically connected to the emergency electrical generator and the one or more additional electrical power sources. Aircraft sensors provide data regarding emergency electrical power availability and emergency electrical power demand. A controller for controlling the emergency electrical generator determines emergency electrical power demand and emergency electrical power availability based upon data from the aircraft sensors. The controller controls the emergency electrical generator based upon the emergency electrical power demand and the emergency electrical power availability.Type: ApplicationFiled: February 28, 2011Publication date: August 30, 2012Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Adam M. Finney, Michael Krenz, Carl A. Wagner, David L. Jacques
