Project Description

Speed Sensor for Planetary EDL: "SPRY", Phase I
The goal of this Phase I and Phase II efforts is to develop a micro atmospheric data sensor suitable for planetary entry, descent, and landing (EDL) maneuvers, in response to NASA�s S4.01 Planetary Entry Descent and Landing. Michigan Aerospace Corporation (MAC) is proposing to develop a compact, rugged optical atmospheric data sensor capable of measuring free stream velocity during EDL; this sensor will use a novel microresonator approach as part of its light processing path, allowing unprecedented compactness and ruggedness. Phase I will entail the design and preliminary demonstration of the concept. A prototype atmospheric data sensor will be fabricated in Phase II and tested using a calibrated flow field. More »
