Abstract: A ram air turbine control valve includes a sleeve, a spool, and a return housing. The sleeve defines a first exit port disposed proximate a first end of the sleeve and defines a second exit port disposed between the first exit port and the first end. The spool is radially contained within the sleeve and is movable between a first position and a second position. The return housing is coupled to the first end of the sleeve and defines a cavity that receives a biasing member that engages the spool.

Abstract: A toggle assembly includes a first joint member having a first lug and a second lug, a second joint member, and a third joint member. The second joint member has a first arm that receives a first rolling element, a second arm that receives a second rolling element, a third arm, and a fourth arm. The second joint member is pivotally connected to the first joint member via a first pin that extends through the first lug, the first rolling element, the second rolling element, and the second lug. The third joint member has a third lug and a fourth lug disposed opposite the third lug. The third joint member is pivotally connected to the second joint member via a cross rod pin that extends through the third lug, the third arm and the fourth arm.

Abstract: A system for axially retaining two coaxial components includes an inner component having an annular compression groove formed in a radially outer surface thereof, an outer component having an annular engagement groove formed in a radially inner surface thereof, and a split retaining ring installed in the annular compression groove of the inner component, wherein the split retaining ring is adapted for movement between a radially compressed condition to facilitate axial engagement of the inner component within the outer component and a radially expanded condition to facilitate radial engagement of the split retaining ring in the annular engagement groove of the outer component, so that the inner and outer components are axially locked together.

Abstract: A retaining ring configured to retain a shaft to a sleeve to fix the shaft rotationally and axially to the sleeve can include a first portion configured to install around the shaft and within the sleeve. The first portion can include one or more first curved sections and at least one first portion flat. The retaining ring can include a second portion configured to install around the shaft and moveable relative to the first portion, the second portion comprising one or more second curved sections and at least one second portion flat. The first portion flat can be defined between a plurality of the first curved sections, and wherein the second portion flat can be defined between a plurality of the second curved sections, for example.

Abstract: A power extraction system is provided and includes a low-pressure spool of a gas turbine engine, the low-pressure spool being rotatable at an input rotational speed between a first minimum speed and a first maximum speed, downstream components rotatable at an output rotational speed between a second minimum speed and a second maximum speed and a transmission assembly by which rotations of the low-pressure spool at the input rotational speed are transmittable at the output rotational speed to the downstream components. The transmission assembly includes clutches and a controller configured to control openings and closings of the clutches according to an upshifting algorithm whereby a torque applied by the downstream components is used to reduce the output rotational speed to an output speed of a gear into which the transmission assembly is shifting.

Abstract: A system can include a first generator configured to operate in a first speed range to produce a predetermined output characteristic, a second generator configured to operate at a second speed range different from the first speed range to produce the predetermined output characteristic, and a controller configured to activate the first generator at and/or above a first low activation speed and at and/or below a first high activation speed within the first speed range. The controller can be configured to activate the second generator at and/or above a second low activation speed within the second speed range. The controller can be configured to deactivate the first generator at and/or above a first high deactivation speed. The controller can be configured to deactivate the second generator at and/or below a second low deactivation speed.

Abstract: A ram air turbine movable between a stowed position and a deployed position is provided including a rotatable hub assembly. A hub face is arranged at a first end of the rotatable hub assembly. The hub face has a non-planar configuration such that a limited portion of a surface area of the hub face is arranged within a plane oriented perpendicular to a direction of travel of an airflow upstream from the hub face when the ram air turbine is in a deployed position.
