Inflator having an enhanced cooling effect on a motor thereof


An inflator includes a box and a compressor unit installed in the box. The box is composed of a cover and a base, which are respectively provided with upper and lower airflow-guiding members, which can quickly guide the air current generated by a cooling fan of the compressor unit to enter the motor's housing via two openings of the housing and to flow out of the motor's housing via downstream through holes of the housing, thus dissipating the heat generated by a rotor assembly in the motor, so that heat is not easy to accumulate in the motor, so that maximum power output of the motor can be achieved, and the performance and service life of the motor can be increased..

Method for operating a gas turbine


A gas turbine having a compressor is controlled at least by controlling an opening of variable inlet guide vanes between a maximum opening and a minimum opening. A function indicative of the mechanical stress undergone by compressor blades downstream of the variable inlet guide vanes has an increasing line trend from the maximum opening to the minimum opening of the variable inlet guide vanes.

Supplemental electromagnetic turbocharger actuator


A turbocharger system for an engine includes a rotor, a primary bearing system arranged to axially and radially support the rotor to rotate on a central rotational axis, a compressor coupled to a rotor to rotate with the rotor, a turbine coupled to the rotor to rotate with the rotor, and an electromagnetic actuator adjacent to the rotor. The electromagnetic actuator selectively acts on the rotor and supplements the axial support of the primary bearing system by applying a magnetic force on the rotor in a direction parallel to the central rotational axis of the rotor..
