The Arnold Engineering Development Center (ALDC) has been under contract since December 1973 to modify existing equipment and to design, fabricate, and install new hardware to perform an MHD Performance Demonstration Experiment. The objective of the experiment is to demonstrate that a generator simulating a commercial-sized device can convert 16 to 18 percent of the available thermal energy into electrical power. This report described fabrication, installation, and testing of hardware for this experiment during the period from October 1, 1977, to September 30, 1978. In the past year, fabrication of the high performance generator channel was completed, and satisfactorily pressure and electrically checked. The coils and approximately 95 percent of the coil force containment structure were installed on the 6 Tesla magnet. Fabrication of the outer insulation panels for the magnet was completed. The magnet is to be cryogenically cooled with liquid nitrogen. During the past year, analytical studies to provide guidance in performing the cooldown were completed and are presented. The preliminary design of the cooling manifold system to provide the required control in accordance with the results of the analytical studies was also completed and is reported. Additional testing of the burner system with the diagnostic section installedmore » was conducted and the results for seeded and unseeded operation are included.« less |
