Principles of Helicopter Aerodynamics

Creator: J. Gordon Leishman | Science - 2002-12-23

This book, written by an internationally recognized expert, provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft.

Publisher: Cambridge University Press

About this book
Helicopters are highly capable rotating-wing aircraft with the unique ability to take off and land vertically, to hover, and to fly forward, backward, or sideways. They also have high noise levels, significant vibrations, and relatively large power requirements. This book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft. It covers the basics of aerodynamic analysis, helicopter performance and design, and advanced topics, including airfoil flows and unsteady aerodynamics. Every chapter includes numerous illustrations, a bibliography, and homework problems. Advanced undergraduate and graduate students, practicing engineers, and researchers, will welcome this useful text.

Principles of Helicopter Aerodynamics with CD Extra

Creator: J. Gordon Leishman | Science - 2006-04-24

Written by an internationally recognized teacher and researcher, this book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft such as tilt rotors and autogiros.

Publisher: Cambridge University Press

About this book
Written by an internationally recognized teacher and researcher, this book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft such as tilt rotors and autogiros. The text begins with a unique technical history of helicopter flight, and then covers basic methods of rotor aerodynamic analysis, and related issues associated with the performance of the helicopter and its aerodynamic design. It goes on to cover more advanced topics in helicopter aerodynamics, including airfoil flows, unsteady aerodynamics, dynamic stall, and rotor wakes, and rotor-airframe aerodynamic interactions, with final chapters on autogiros and advanced methods of helicopter aerodynamic analysis. Extensively illustrated throughout, each chapter includes a set of homework problems. Advanced undergraduate and graduate students, practising engineers, and researchers will welcome this thoroughly revised and updated text on rotating-wing aerodynamics.

    Best mini helicopter at this price!

    I have a small squadron of mini helicopters and this one is by far the best so far. I read great reviews of the Syma S107. I was quite pleased with it compared to some of the older Syma models. Then I saw the positive reviews for this and thought I would give it a go. It flies incredibly well! Quiter than the other seven helicopters I have and so stable, smooth, and responsive. It is a little slow with forward and reverse momentum, but not bad. Slow is easier to control...maybe that was intentional. We fly these every day in the office and this hands down outperforms everthing else.For those comparing models, here you go:Syma S109 Apache- ExcellentSyma S105G (Sport Helicopter) Very Good -Fastest, stable, but somewhat loud, durable metal frameSyma S107G- (Sport Helicopter) Very good- nearly identical to S105 but a little slower, different scheme,older?Syma S026 Chinook- Looks cool, flies ok, but hard to control. Too much power for its weight;... 5/5 Anotherflyer (Alaska) - See all my reviews Verified Purchase(What's this?) I have a small squadron of mini helicopters and this one is by far the best so far.

    Syma Military Helicopters

    I own all the Syma Mini Military helicopters. Here is my review for all 5.1. S108G Cobra. By Far the fastest and the most aggressive of the helicopters. This one takes a little bit of time to get used to and is for the more experienced flyer. Its super fast and super durable.2. S109G Apache. Another good helicopter from Syma. Runs the same as the Cobra. Fast and swift.3. S026G Chinook. A good beginner helicopter. Very stable in flight. It can be fast if you want it to be or it can be slow. This is one of my favorites out of the series.4. S102G Black Hawk. My brother has the S107G and this flies just like it. This is probably the best helicopter that syma makes. Extremely stable and can take a serious beating. (But so can all the others.) It will fly at the speed you want it to from slow to fast and takeoffs and landings are extremely smooth.5. S111G Coast Guard Rescue. This too is a fine product from syma. Super smooth flyer... 5/5 APR - See all my reviews Verified Purchase(What's this?) I own all the Syma Mini Military helicopters.
