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.

    Syma

    Its super smooth, easy to control and looks cool

    The S111g flies perfectly. Its super smooth, easy to control and looks cool. I found this heli flies exactly the same as the Syma s107g, its well balanced and you get a solid 6-7mins out of the battery which is good enough for beginners. Im more of an intermediate, but still had a lot of fun with it.I recommend this heli highly. I also can‘t fault any of the other Syma helicopters that Ive flown, they truly are well built for such a cheap price.The only knock I have on this helicopter is the forward speed. Its built for beginners, so its stable. Id say almost too stable and doesnt go very fast in fwd direction. You can get around this by adding some weight to the nose of the helicopter. I used some sticky tape and a few ball bearings. This gives the helicopter much better forward. BUT DONT DO THIS UNTIL YOU ARE GOOD AT FLYING.I also bought an Eagle Pro Helipad, which is slightly bigger than the helicopter and makes for some fun landings... 5/5 Rebecca - See all my reviews Verified Purchase(What's this?)

    Easy to Fly- Great for Beginners

    Right out of the box this Syma S111G flies nice and smooth. This helicopter is perfect for a beginner. A few helicopters my husband has gotten lately have taken a bit getting used to but this one just had such easy handling. It is very easy to control and fly around the house. It's a very well balanced helicopter. With another Syma we have I had to shut off our A/C in the house because just a little gust of air would blow it out of control. On a full charge we get a good 10 minutes or so of fly time which isn't bad at all. This is a solid helicopter. It can run into walls, get slammed on the floor with some failed attempts at proper landings, and still be perfectly fine. Also, it can even take off on it's side which my husband and I thought was pretty cool. I went to go pick it up to put in the upright position and he ended up taking right off while it was down. With his helicopters he loves practicing his landing on his Eagle Pro Helipad:... 5/5 Melissa Anne (Nebraska) - See all my reviews Verified Purchase(What's this?)

    Syma S111G - Pilot a helicopter for the price of a DVD

    If you are looking for a remote controlled helicopter this one is worth considering. It is suitable for a 'first time pilot' and should keep more experienced ones happy as well. The helicopter performs very well and also looks great. You can charge it from the transmitter although, I have been using a USB cable charger that came with it, charging it from my laptop to conserve the transmitter batteies. Charging this way takes close to 1 hour and you can expect around 7-8 minutes flight per charge. This is normal for this type of model. The helicopter is controlled by an infrared transmitter which means it is only suitable for indoor use. Three channel proportional control means you can contol height, rotate left and right and move forwards and backwards, all at a variable rate. Controls are sensitive and respond very well and a single 'trimmer' allows you to make sure direction does not drift left or right. If you have not flown a helicopter before I would suggest first making sure you... 5/5 Bazz... - See all my reviews Verified Purchase(What's this?)
