Problem Of Selection Of Parameters Of A Helicopter, Which Carries Out A Two-Stage Transportation Mission (p. 29 – 43)
B.L. Artamonov, V.N. Zhuravlev, V.I. Shaidakov
The described research investigates the features of design of a single-rotor transport helicopter, which carries out a two-stage transportation mission. The paper gives an outline of mathematical models, which are proposed by the authors for analysis of helicopter weight and aerodynamics. The application of the proposed models is illustrated on the example of analysis of the ability of Mil-38 helicopter to complete an offshore transportation mission. This example is also used to investigate and show the influence of the main rotor diameter on technical effectiveness criteria of a helicopter, which is designed for a specified mission.
Keywords: single-rotor helicopter; two-stage transportation mission; mathematical model; weight analysis; aerodynamic analysis.
