  • Patent number: 9267384
    Abstract: 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.

  • Publication number: 20130076120
    Abstract: An emergency power system for use on an aircraft includes an emergency electrical generator coupled to a mechanical power source for generating emergency electrical power. An electrical power distribution network connects the emergency electrical generator to a plurality of electrical loads. A controller controls the electrical power distribution network to selectively couple and decouple the electrical loads to and from the emergency electrical generator based upon a priority rank assigned to each of the electrical loads.

  • Publication number: 20120221157
    Abstract: 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.

  • Publication number: 20120011839
    Abstract: An auxiliary hydraulic power generation system includes a first spool including a turbine. A fan is coupled to the first spool, the fan operable to drive the first spool in a windmill condition in which the turbine fails to provide rotational drive to the fan. An auxiliary variable displacement hydraulic pump is selectively driven by the first spool in the windmill condition to augment a hydraulic power source.
