s4655d8946f	Thomas Bradley Apker	Experimental Investigation and Modeling of Time Resolved Thrust of a Flapping Wing Aircraft	2010		.txt	text/plain	205	9	52	This motion was used to develop phenomenological linear models of flapping wing thrust generation. This study showed that the spectral content of the flapping wings extended to 15 times the flapping frequency, well above the resonant frequency of the mass-spring-damper system formed by a load cell and flapping mechanism.	cache/s4655d8946f.txt	txt/s4655d8946f.txt
