MIL DESIGN BUREAU HEAVY-LIFT HELICOPTERS

The history of design and development the heavy-lift V-12 and Mi-26 he licopters In the Mil Design Bureau is considered. The paper shows the sequence in which different versions were considered, the various conf igurations were investigated and the optimization of parameters was ma de. Approaches used to achieve different degrees of sophistication for separate components are discussed. The research methods of a separate units degree perfection are discussed. Great attention is paid to dis cussion of the innovations in the design of a transmission, rotor and other helicopter elements for a successful result in the creation of t he Mi-26.
