摘要： A process is provided for forming a metallic edge having a three dimensional internal configuration by preparing a metallic edge blank having a two dimensional internal configuration; attaching a flange to the sides of the blank; preheating the blank, forming mandrel and receiver dies to a temperature at which the metal is in a malleable state, with the forming mandrel having an external surface which corresponds to the three dimensional internal configuration of the formed metallic edge; and hot forming the metallic edge by securing the blank within the receiver dies and advancing the mandrel into the inner cavity of the blank through use of a drive means which rotates the mandrel as it advances into the blank while maintaining the blank, mandrel and receiver dies at the malleable temperature.

摘要： An electrical system for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an output circuit or the stator winding of the alternator. A control circuit during a start-up mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the output circuit. During start-up the frequency and voltage of the electrical power to the inverter is controlled as a function of the time and/or rotation speed.

摘要： An electrical system and method for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an output circuit or the stator winding of the alternator. A control circuit during a start-up mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the output circuit and power line. During the power output mode the power line is monitored and the output voltage, frequency and/or phase is matched or synchronized to the power line.

摘要： An electrical system for a turbine/alternator comprising a gas driven turbine and permanent magnet alternator rotating on a common shaft comprises an inverter circuit connectable either to an AC output circuit or the stator winding of the alternator. A control circuit during a startup mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the AC output circuit. Thus, during the startup mode, the alternator functions as a motor to raise the speed of the turbine to a safe ignition speed and in the power out mode the electrical system outputs to the AC output circuit, electrical power having a frequency unrelated to the rotational speed of the alternator.
