The objective is to support highly focused, innovative, fundamental/applied research approaches that will complement the Feasibility Assessment program for Space Based, Multimegawatt, MHD Power Systems. The program consists of a series of related tasks described as follows: (1) Analysis and optimization of the proposed cryogenically cooled air core transformer. The nominal input power into the transformer shall be 400 kW switched at 1 kHz. Following optimization of the proposed conceptual design, the contractor shall perform an engineering design of the transformers in sufficient detail to permit outside vendor fabrication. The design will be suitable for subsequent scale up to multimegawatt power level for space based applications; (2) Transformer procurement and assembly; (3) Performance of low power (up to hundreds of volt-amperes), room temperature and cryogenic testing. The measurements shall include the impedance, self inductance, parasitic inductance and capacitance of each coil and their mutual inductance. These measurements shall be performed at room, liquid nitrogen, and liquid hydrogen temperature; and (4) Performance of full power transformer testing under cryogenic (liquid hydrogen) conditions utilizing the existing Avco Mk VI MHD facility equipment which includes the Mk VI current control circuits, magnet power supply and channel load. The nominal input power level shall be 400 kW, 1 kHz square wave. The electrical measurements performed in Task 3 shall be repeated in this task.
