Description
Basic Helicopter Aerodynamics is widely appreciated as aneasily accessible, rounded introduction to the first principles ofthe aerodynamics of helicopter flight. Simon Newman has broughtthis third edition completely up to date with a full new set ofillustrations and imagery. An accompanying website www.wiley.com/go/seddoncontains all the calculation files used in the book, problems,solutions, PPT slides and supporting MATLAB® code.
Simon Newman addresses the unique considerations applicable torotor UAVs and MAVs, and coverage of blade dynamics is expanded toinclude both flapping, lagging and ground resonance. New materialis included on blade tip design, flow characteristics surroundingthe rotor in forward flight, tail rotors, brown-out, blade sailingand shipborne operations.
Concentrating on the well-known Sikorsky configuration of singlemain rotor with tail rotor, early chapters deal with theaerodynamics of the rotor in hover, vertical flight, forward flightand climb. Analysis of these motions is developed to the stage ofobtaining the principal results for thrust, power and associatedquantities. Later chapters turn to the characteristics of theoverall helicopter, its performance, stability and control, and theimportant field of aerodynamic research is discussed, with somereference also to aerodynamic design practice.
This introductory level treatment to the aerodynamics ofhelicopter flight will appeal to aircraft design engineers andundergraduate and graduate students in aircraft design, as well aspractising engineers looking for an introduction to or refreshercourse on the subject.
Reviews / Votes
"In summary, this greatly improved edition is going to beof interest to all those young people wishing to embark on theunderstanding of the helicopter, without the fuss of too muchdetail and too much theory." (Aeronautical Journal, 1 August2013)More details
