EVALUATION OF LENTICULAR SPIRAL ARRAY

Abstract

The purpose of the program was to support the launch of a pseudo passive satellite. Part of the requirements include the capability to add energy to the satellite orbit through absorbtion or reflection of solar energy (solar sail) and the temperature stabilization of tunnel diode amplifiers in a space environment. A lightweight packageable solar sail material possessing optical characteristics of low reflectivity and high emissivity on one side and high reflectivity and high emissivity on the opposite side was then tested under simulated space conditions. A flexible thermal coating containing zinc oxide was rotoflex tested for material reliability at various test temperatures and then tested under simulated space conditions. The goals of the procurement were then changed as the satellite requirements were negated. Scattering characteristics, load dependent and load independent, of spiral antennas in arrays and under isolated conditions were to be determined. A computer program (Fortran IV) was developed to determine the parameters of single antenna element.
