Abstract:It is a well known fact that the forward speed of a single main rotor helicopter is limited because of the compressibility effects on the advancing side and reverse flow and dynamic stall on the retreating side. Compound helicopters are a viable option which could increase the forward speed while minimizing hover penalty. Much analysis has been carried out on compound helicopters but the test data are lacking. The present research aims to systematically bridge this gap, the first step of which was to study lif… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
