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.
