VULCAN. HIGH-TEMPERATURE ANTENNA INVESTIGATION AND DEVELOPMENT.
CORNELL AERONAUTICAL LAB INC BUFFALO N Y
Work was continued on the preliminary studies of the various types of antennas to determine which types would have the highest probability of op erating successfully in a 2000 F environment. An experimental study was started on the slot, annular slot, and scimitar annnnnas operated at room temperature. A proposed ground plane assem bly, consisting of a small heated central section and a large thermally isolated metal plane, was designed and tested successfully on the CAL an tenna range. Preliannary design of the central or thermal section of the ground plane was com pleted and construction was started. A materials investigation and fabrication techniques study has been initiated in order to determine which dielectric materials are suitable for high tem perature use, to determine suitable conducting coatings, and to develop coating and sealing techniques for high temperature operation.
