An operational status of a gas turbine engine of the hybrid electric aircraft is monitored. The battery system is charged at a second charging current received from the generator driven by the gas turbine engine responsive to determining that the gas turbine engine is in a taxi state, where the second charging current is less than the first charging current. Charging of the battery system is halted based on detecting a transition of the gas turbine engine from the taxi state to an off-idle throttle state.

  • Patent number: 10767619
    Abstract: A closed system that captures energy derived from the head differential rather than open-water flows velocities while reducing potential environmental damages and costly maintenance due to bio-fouling. This energy density available in a tidal range is increased substantially via convergent “nozzles” to produce an optimal speed for power generations with the turbine sections, thereby significantly increasing the tidal energy captured by this system, even at sites where tidal energy is low (e.g., small to medium tide ranges, such as found along the East and Gulf Coasts of the United States).

  • Patent number: 10605225
    Abstract: System and method for controlling operation of a hydroelectric production system comprising electrical actuators operably connected at opposite positions of a gate operating ring for rotating the wicket gates to a desired position. The system receives a single control signal designed for a hydraulic system comprising hydraulic actuators operably connected to a single fluid reservoir and configured to work in tandem to produce simultaneous and opposite axial movements. The system comprises a control interface adapted to produce new control signals, each new signal being intended to a different electrical actuator to cause the electrical actuators to have axial movements which are identical in speed and in opposite directions to substantially imitate the exact movement of the hydraulic actuators onto the gate operating ring. The system is configured to introduce a dampening effect to reduce sudden acceleration and deceleration which is purposely used in hydraulic systems to overcome friction and static effects.
