Jet-Propelled Rotor-Blade Construction
The Journal of the Helicopter Association of Great Britain, 1951In presenting this paper an attempt has been made to outline some of the additional problems which are connected with the design and construction of rotor blades driven by jets at the tipsThe complications which arise when ram or pulse jets are fitted are not discussed in detail as it is considered that these problems are also included among those ...

Jet Propulsion of Rotor Blades
The Journal of the Helicopter Association of Great Britain, 1950From the very beginning of helicopter development the designer has had two major problems, one associated with the balancing of the torque reaction on a mechanically driven rotating system, and the other one that of mechanical difficulties associated with the transmissions ISACCO for instance realized right at the beginning that what he wanted was some

Rotor Blade Flapping Criteria Investigation.
1976Abstract : The objective of this study was to identify helicopter characteristics critical to main rotor flapping and to attempt to establish flapping design criteria. Three helicopter types and three rotor systems were simulated in steady flight an maneuvers using the hybrid version of C81, Rotor craft flight Simulation Program.

Analysis of composite rotor blades
1996The purpose of this chapter is to provide an insight into the behavior of composite rotor blades, their modeling and the associated analysis methodologies. From a structural point of view, blades are usually treated as slender structures. This category includes all structures where one of their dimensions is much larger than the others.
