The telescopic hydrokinetic turbine system is a device meant for lifting the burden of manufacturing, installing, and maintaining hydrokinetic systems in the water. The device attempts to overcome the issues faced by present day hydrokinetic systems. To accomplish this, the device includes a light weight and easy to carry and install design, a telescopic pillar to align itself with the tide direction or even to leave the body of water for maintenance. Electrical parts are not submerged but instead remain onshore in a small cabin or housing. Further, by adding the use of multiple diffusers, the water flowing into the turbine is made smoother and the overload of water is able to be evacuated and swiped by the fins. The diffusers increase the blades working capacity while homogenizing the water flow and avoiding the phenomena of vibrations and cavitation, thereby increasing efficiency.

A variable vane assembly for a gas turbine engine, the variable vane assembly including: a plurality of vanes arranged into a plurality of stages, each one of the plurality of vanes being configured for rotation about an axis through movement of a vane arm secured to each one of the plurality of vanes at one end and a sync ring of each one of the plurality of stages at another end; and a plurality of bell cranks operably coupling the sync ring of each one of the plurality of stages to a self-retained linkage via a stud of each one of the plurality of bell cranks, the stud of each one of the plurality of bell cranks being rotatably received in a corresponding opening of the self-retained linkage in an alternating fashion such that only a single shear interface is provided between each one of the plurality of bell cranks and the self-retained linkage.

An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a rigid linkage. The translating structure is configured to translate relative to the fixed structure. The blocker door extends between a blocker door first end and a blocker door second end. The translating structure is pivotally attached to the blocker door at the blocker door first end. The rigid linkage includes a first pivot attachment, a second pivot attachment and a third pivot attachment. The first pivot attachment is coupled to the fixed structure. The second pivot attachment is coupled to the translating structure. The third pivot attachment is coupled to the blocker door at the blocker door second end.

A cam isolation system for a gas turbine engine compressor actuator includes a torque tube. The system also includes a cam bracket operatively coupled to an engine case structure, the cam bracket defining a slot. The system further includes an actuator bracket operatively coupled to the torque tube at a first end of the actuator bracket, the actuator bracket having a pin disposed within the slot of the cam bracket.

A synchronizing assembly including: a synchronizing ring having a countersunk orifice; and a bumper assembly comprising: a bumper at least partially enclosing a cavity, the bumper comprising an outward side, an inward side opposite the outward side, a first side extending between the outward side and the inward side, a first opening on the outward side extending into the bumper to define a first portion of the cavity; and a second opening on the first side extending into the bumper to define a second portion of the cavity; and a bolt comprising a bolt head and a bolt shank, wherein the bolt shank extends through the first opening and the bolt head is secured within the second portion of the cavity, wherein the bumper further comprises a raised boss extending away from the outward surface, the raised boss configured to mate with the countersunk orifice of the synchronizing ring.

A gripper for holding a wind turbine blade when the wind turbine blade is being transported. The gripper comprises a lower blade holding structure configured to engage an underside of the wind turbine blade, an upper blade holding structure configured to engage an upper side of the wind turbine blade and a force transfer mechanism operatively coupled to at least one of the lower or upper blade holding structures. The force transfer mechanism is configured to increase the force applied between the lower blade holding structure and the underside of the wind turbine blade and/or between the upper blade holding structure and the upper side of the wind turbine blade when the wind turbine blade is accelerated during movement along a central longitudinal axis of the wind turbine blade.

An oscillation system suitable to convert a manual water monitor into an automated oscillating water monitor, without adversely changing the ergonomic orientations of the water monitor, comprising a flange configured to couple the water monitor to a standpipe and provide a source of motive water, and a conversion device to convert motive water to monitor oscillations.

A synchronizing assembly including: a synchronizing ring having a countersunk orifice; and a bumper assembly comprising: a bumper at least partially enclosing a cavity, the bumper comprising an outward side, an inward side opposite the outward side, a first side extending between the outward side and the inward side, a first opening on the outward side extending into the bumper to define a first portion of the cavity; and a second opening on the first side extending into the bumper to define a second portion of the cavity; and a bolt comprising a bolt head and a bolt shank, wherein the bolt shank extends through the first opening and the bolt head is secured within the second portion of the cavity, wherein the bumper further comprises a raised boss extending away from the outward surface, the raised boss configured to mate with the countersunk orifice of the synchronizing ring.

A tidal current generator relates to a tidal current generator that can efficiently generate power by separating an on-water power generation unit and an in-water power collection unit, that allows for easy management of facilities on the water because the facilities in the water can be easily pulled up on the water even if they break, that can maximally use the flow of tides using a connection rope and a groove formed on a rotary propeller, and that can maximize efficiency by controlling the number of power connections between a rotary unit and an on-water power generator in accordance with the states of the flow of tides to prevent waste or deficit of power transmission.
