摘要： The present invention relates to a ram air turbine which is preferably used in conjunction with a refueling pod on an aircraft for purposes of operating a fuel pump and/or reeling mechanism for paying in and paying out a fuel line. The turbine generally comprises a rotatable housing having a main turbine output shaft disposed therein and rigidly connect thereto. A plurality of variable pitch turbine blades extend outwardly from and are cooperatively engaged to the housing such that rotation of the turbine blades causes simultaneous rotation of the housing and output shaft. Means are provided within the housing for establishing a preset reference rotational speed for the output shaft. Additionally, a control means cooperatively engaged between the turbine blades and the reference means is provided for adjusting the pitch of the turbine blades in response to a difference in the rotational speed of the output shaft and the preset reference rotational speed. The ram air turbine further includes both electrical and mechanical braking devices for changing the pitch of the turbine blades when the rotational speed of the output shaft exceeds a pre-determined maximum.

摘要： A blade pitch control mechanism for a ram air driven turbine blade mounted for rotation on a hub assembly having a central axis. A governor control member, including a seat, is mounted on a portion of the hub assembly for reciprocation along the central axis. A first spring acts on the governor control member in a first axial direction. A governor slide member is mounted for reciprocation along the central axis. The blade is in mating engagement with the governor slide member. A second spring acts between the governor slide member and the seat of the governor control member for biasing the slide member opposite the first axial direction. This causes the blade to assume a course pitch when the blade and hub assembly are in storage and to allow the blade to move to fine pitch during start-up. A flyweight is mounted on the hub assembly and engages the governor control member for acting against the first spring to control blade pitch and govern turbine speed after start-up.

摘要： An aerogenerator is provided with a rotor attached to one end of a variably orientable axis. The axis is, in turn, attached to apparatus for either using the energy produced by the rotatable rotor or apparatus for transforming the energy produced by the rotor. The apparatus includes a system for regulating the velocity of rotation of the rotor as either a function of the force of incident wind on the rotor or as a function of the value of energy which is desired to be produced by the aerogenerator. The system includes a device for automatically controlling the angular movement of the axis as well as a device for measuring the velocity of the rotation of the rotor, whereby the axis can be inclined so that a substantially constant rotational velocity is achieved. A method of regulating the rotational velocity includes measuring the actual velocity, establishing a desired reference velocity, comparing the actual and reference velocities, and altering the orientation of the axis to which the rotor is attached in order to minimize the difference between the measured and reference velocity values.

摘要： The test rig can be used for testing a blade pitch measurement system of a variable pitch propeller system. The test rig can include a first mount rotatably mounted to the frame and configured to receive the feedback device, a rotation motor drivingly coupled to rotate the ring mount relative to the frame around a rotation axis, a second mount configured to receive the pitch sensor, a mechanism configured for moving the second mount along an orientation parallel to the rotation axis, and a controller configured to control the rotation of the rotation motor to a variable rotation speed, and for controlling the movement of the second mount to variable positions via the mechanism.

摘要： Aerial vehicles may be equipped with propellers having pivotable blades that are configured to rotate or fold when the propellers are not rotating under power. A pivotable blade may rotate about an axis of a propeller with respect to a hub in the presence of wind flow until the pivotable blade is coaligned with a fixed blade, in a direction opposite to the wind flow. A pivotable blade may also fold over a hub of a propeller in the presence of wind flow, with the pivotable blade and a fixed blade being oriented in directions opposite to the wind flow. A center of mass of the pivotable blade may be caused to be on the same side of an axis as a center of mass of a fixed blade, even where the axis is not normal to the wind flow, thereby reducing an amount of drag generated by the propeller.
