In a preliminary design study of a rotor system for a Hot Cycle heavy-lift helicopter, the following items were accomplished. 1 An analytical procedure was developed that permitted calculation of fully coupled blade response and dynamic stability characteristics 2 parametric and configuration studies involving basic characteristics of the rotor system were conducted 3 design layouts, structural design studies, and detailed weight analyses were made design and analysis were limited to the integrated lift- propulsion system with emphasis on the rotor system 4 preliminary design was completed, and performance of the optimum rotor for the heavy-lift mission requirements was determined 5 a fully coupled blade loads analysis of the optimum rotor was made and 6 a full-scale mockup of the rotor hub area was constructed.
