摘要： A high voltage direct current (DC) tether for an airborne wind turbine has a reduced weight compared to conventional tethers. The weight reduction is achieved by using one conductor in the center of the feeder and the shielding of the feeder as a second conductor. A mechanical strength element is disposed in between the center conductor and the shielding. In this configuration, the mechanical strength element acts also as an insulator. The center conductor and the shielding can be made of aluminum or copper. The strength element can be a high strength fiber composite, woven such as VECTRAN® or SPECTRA®. The main weight savings are due to using the shielding for multiple purposes—as a conductor, as lightning protection and as an electromagnetic interference (EMI) effects barrier, while providing strength to the tether, and from using the mechanical strength element (VECTRAN® or SPECTRA®) as an insulator. The shielding is typically used as the return conductor.
摘要翻译：与常规系绳相比，用于机载风力涡轮机的高压直流（DC）系绳具有减小的重量。减轻重量是通过在供料器的中心使用一个导体和将供料器的屏蔽作为第二导体来实现的。机械强度元件设置在中心导体和屏蔽之间。在这种结构中，机械强度元件也用作绝缘体。中心导体和屏蔽层可以由铝或铜制成。强度元素可以是高强度纤维复合材料，如VECTRAN®或SPECTRA®等编织物。主要的重量节省是由于使用屏蔽作为导体，作为导体，作为防雷和电磁干扰（EMI）效应屏障，同时为系绳提供强度，并使用机械强度元件（VECTRAN®或 SPECTRA®）作为绝缘体。屏蔽通常用作返回导体。

摘要： A rotor resistor and switch combination may cause a starter/generator device to function as an asynchronous device when in a start mode. Thus, starting torque may result. A starter/generator device may include an exciter rotor winding, a main rotor winding, and a resistor and switch combination positioned between the exciter rotor winding and the main rotor winding to control a flow of current in the main rotor winding during a start mode of the starter/generator device. A method of optimizing starting torque of a starter/generator device without a start controller unit during a start mode may include providing a main rotor winding of the starter/generator device, and providing a control to control a flow of current in the main rotor winding during the start mode.

摘要： A starter-generator system is configured to supply power to an aircraft electrical bus having a rated AC voltage magnitude, or receive power from a start converter, and includes a rotor and a stator. The stator is disposed at least partially around at least a portion of the rotor and has at least one multi-phase stator winding set wound thereon that has an increased number of turns per phase that is greater than a least number of turns per phase needed to supply power to an aircraft electrical bus at the rated AC voltage magnitude. The increased number of stator turns results in reduced current drawn by the starter-generator during the motor mode, which improves the efficiency and introduces other benefits to the overall starting system.

摘要： A starter-generator system is configured to be operable at multiple variable frequencies. The starter-generator includes a rotor and a stator. The rotor is configured to rotate and has a single main field winding wound thereon. The stator has at least a first stator winding set and second stator winding set independently wound thereon. Upon electrical excitation and rotation of the rotor the starter-generator supplies electrical power from each of the stator winding sets at different frequencies. Also, upon electrically exciting one or both of the stator winding sets with appropriate AC power, the rotor will rotate and generate a starting torque.

摘要： A generator system is configured to supply two phase excitation current from an exciter rotor to a main generator rotor. When driven by a variable speed prime mover, the generator system provides relatively constant frequency AC power by independently controlling the main rotor flux rotational speed. The generator system includes an exciter stator that induces current in the exciter rotor windings at a desired frequency and phasing. The exciter rotor windings are electrically connected to the main rotor windings to provide two-phase excitation current to the main rotor windings. Excitation is supplied to the exciter stator from an exciter controller, which controls the frequency and phasing of the exciter excitation, based on the rotational speed of the generator, to maintain a constant output frequency. The exciter frequency control function of the exciter controller may be eliminated when the generator system is driven by a constant speed prime mover or when a narrow band variable frequency output is required.

摘要： A starter-generator system may be used to supply sufficient starting torque to start an aircraft main engine. The main starter-generator stator winding may be connected to a constant frequency (CF) power source to create a rotating field in the main starter-generator air gap. This rotating field, in turn, may induce current on the main rotor winding, which may be a closed circuit formed by main rotor field winding and exciter armature winding. The interaction between the main rotor current and the air gap flux may give rise to the starting torque to start the main engine. Adjusting the voltage supplied to the exciter stator field winding can modify the induced voltage and current on the rotor circuit to control the rotor current and starting torque. The starter-generator system may also be used to start an aircraft main engine by directly connecting the main stator winding to a power source without powering the exciter stator.
