Performance of a steel spar wind turbine blade on the Mod-0 100 kW experimental wind turbine [PDF]
The performance and loading of a large wind rotor, 38.4 m in diameter and composed of two low-cost steel spar blades were examined. Two blades were fabricated at Lewis Research Center and successfully operated on the Mod-0 wind turbine at Plum Brook. The

How wing compliance drives the efficiency of self-propelled flapping flyers
, 2010 Wing flexibility governs the flying performance of flapping wing flyers. Here, we use a self-propelled flapping-wing model mounted on a ``merry go round'' to investigate the effect of wing compliance on the propulsive efficiency of the system.

Suns-V$_\textrm{OC}$ characteristics of high performance kesterite solar cells
, 2014 Low open circuit voltage ($V_{OC}$) has been recognized as the number one problem in the current generation of Cu$_{2}$ZnSn(Se,S)$_{4}$ (CZTSSe) solar cells. We report high light intensity and low temperature Suns-$V_{OC}$ measurement in high performance

PERFORMANCE OF THE CAPSTONE C30 MICROTURBINE ON BIODIESEL BENDS. [PDF]
, 2007 This report will describe the tests of biodiesel blends as a fuel in a Capstone oil fired microturbine (C30) with a nominal rating of 30 kW. The blends, in ASTM No. 2 heating oil, ranged from 0% to 100% biodiesel. No changes were made to the microturbine system for operation on the blends.
