The first significant improvement - if one excepts the advent of the turbine - was probably achieved by France's SNIAS company (now Aerospatiale) who exploited to the full the properties of elastomers to reduce the number of parts of the rotor head. The resulting Starflex rotor was actually killing several birds with one stone: not only were the number of parts and hence the manufacturing and maintenance costs as well as weights cut down, but most important for military applications, the high reliability thus achieved permitted a virtual all-time readiness of the rotor thanks to the "on-condition" maintenance concept.
