Affordable, Precision Reflector Mold Technology (PDRT08-029-1), Phase II

Completed Technology Project

Project Introduction

Affordable, Precision Reflector Mold Technology (PDRT08-029-1), Phase II
Future NASA missions including the Cornell Caltech Atacama Telescope (CCAT) and Global Atmospheric Composition Mission (GACM), require 1 to 4 meter aperture, submillimeter-wavelength, primary reflector (mirror) segments. Astigmatic surface errors in a composite primary reflector and inconsistent radius of curvature in composite reflector segments limit application of composites to instruments. This project proposes to improve upon state-of-the-art passive reflector surface accuracy by characterizing the behavior and properties of actuated, graphite composite reflector laminates and panels that are suitable for space and earth science instruments. Surface error in composite primary reflectors and inconsistent radius of curvature in composite reflector segments currently limit application of composites to submillimeter wavelength primary mirrors. The goal is to minimize surface error including ROC error. More »
