MATERIALS AND STRUCTURES PROGRAM, HIGH MACH PHASE II. ARC PLASMA INVESTIGATIONS AND ARC TUNNEL MATERIALS STUDIES
Abstract
Progress in the Materials and Structures Program, High Mach Phase II: Arc Plasma Investigations and Arc Tunnel Materials Studies, for the period 1 July through 31 December 1961, is described. During this period, buildup of the 2-Mw arc tunnel facility was continued. Attachment of the large vacuum pumping system, cooling system, and power supply to the 200-kw tunnels was completed. This allows expansion to larger diameters ( 2 in.) in the test section and longer duration test runs ( 10 min). Fabrication of a Gerdien arc, intended to serve as the future plasma sin materials tests, was initiated. Arc calibration and diagnostic techniques to be employed are discussed. The 200-kw arc tunnel facility has been utilized during this reporting period in a continuing materials testing program. Re-entry materials tested included: Graphite cloth- phenolics, and MMM Scotchply No. 202.
