Book Description
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 installed was conducted and the results for seeded and unseeded operation are included.

Book Description
The objective of this experimental research, started late in 1973, is to demonstrate the attainment of MHD performance ona sufficiently large scale to verify that the projected efficiency of the commercial MHD concept is attainable. To perform the experiment, an existing facility at the Arnold Engineering Development Center (USAF) was refurbished and the new systems required for performing the experiment have been designed and built. In particular, the largest systems which have required the greatest expenditure of resources are the generator channel and the 6 Tesla (T) cryogenically cooled magnet. Both of these systems are now complete and the magnet has been tested at low field strengths. During the period between April 1, 1979, and June 30, 1979, the assembly operations on the magnet and its cryogenic cooling system were completed. The pressure testing of the generator channel was completed and the channel was installed in the magnet to facilitate final alignment of the burner. The diffuser assembly operations were completed. The magnet was retested in the warm mode, repeating the tests performed in December 1978 during wich an arc-over occurred. No problems were encountered in the latest tests and the magnet was subsequently cooled to 165°K and pulsed to a peak field strength of 2.9 T. Analytic studies of the operation of the generator with supersonic flow at low magnetic fields were started and are continuing.
