Abstract: A ducted ram air turbine may be used to drive a generator to provide power to an aircraft. The ducted ram air turbine may be used in a pod attached to the aircraft, where the pod is fully powered, cooled and lubricated by devices attached to the ram air turbine. A gearbox may be deployed to control the speed of the turbine for driving various pumps and the like. The speed of the turbine may be controlled by inlet and exit actuators driving inlet and exit doors.

Abstract: An apparatus for determining the fluid level of a container, such as an accumulator, may include both a remote quantity indicator and a direct quantity indicator. The remote quantity indicator may include a remote dial at the end of a flexible cable or an electrical signal receiver receiving an electrical signal from a rotary variable differential transformer (RVDT), such as a potentiometer. The RVDT type of indicator may include an electrical connector on the accumulator to attach an electrical cable to carry the quantity level signal. The direct quantity indicator may include a dial directly mounted on the accumulator. The remote/direct quantity indicators may include, for example, one of the following three combinations: 1) a dial directly on the accumulator and a remote dial at the end of a flexible cable; 2) an RVDT output and a dial directly on the accumulator; and 3) an RVDT output on an accumulator, a remote dial at the end of a flexible cable and a dial directly on the accumulator.

Abstract: A fluid coupler for connecting two hydraulic appliances together without requiring flexible hoses is described. The fluid coupler enables fluid-tight connecting between fixed position components and allows for separating the hydraulic appliances without decoupling the coupler while maintaining fluid-tightness of both appliances after separation.

Abstract: A remote visual liquid quantity indicator comprises a flexible cable within a flexible outer sleeve and allows a user to remotely determine the level of a liquid in a container, such as an accumulator without the need for electrical power or a direct line of sight to the container. The flexible cable may be coupled between a reservoir sweeper of the accumulator and an indicator. Changes in the fluid level of the accumulator may provide a linear movement to the flexible cable, which in turn provides a change to the measurement reading of the indicator. The flexible cable/outer sleeve allows for the complex routing scenarios necessary in the congested spaces surrounding aircraft accumulators.

Abstract: A rotary remote visual liquid quantity indicator allows a user to remotely determine the amount of liquid in a container, such as an accumulator on an aircraft. A flexible rotary cable assembly may be coupled between a rotatable drum and a remote indicator having a rotatable cap, the rotatable drum responsive to axial motion of a sweeper within the accumulator. Changes in the fluid level of the accumulator may be translated into rotational motion of the rotatable drum, which, via the flexible rotary cable assembly, changes a reading on a remotely located indicator.
