Feasibility of simulation of Martian atmospheric processes - atmospheric transportation and deposition of dust and sand, absorption properties, and thermodynamic properties
Thirty watt per pound roll-up solar array feasibility
Principal efforts in this reporting period were applied to preparation of the detail design of the array structure and mechanisms and to manufacturing drawings for a demonstration model of the selected design concept. Analytical support focused on substantiation of the detail design. Additional studies were performed of dynamic criteron effects on components of the wrap drum. Thermal studies were extended to evaluate another thin film (preferred) material for the substrate and its influence on solar cell temperatures. Electrical design considerations included feasibility studies and ramifications of using a new, larger size, solar cell and a new coverglass application concept. Preliminary evaluations suggest improvement in the array power to weight characteristic and net savings in the estimated cost of cell installation. Weight estimates have been up-dated in keeping with refinements in detail design. Performance of this contractor's rollout solar array design is now projected as capable of producing 31.6 watts per pound of weight; excludes estimated improvements from use of new solar cell design.
