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.

    Fun For All Ages Indoor Helicopter

    This is the perfect helicopter for indoor use. Great for all ages! I got this helicopter for my husband and he absolutely loves it. It's very durable which is perfect because so far he has flown it into numerous walls, the ceiling, and slammed it against the floor many times. It takes a while to get used to controlling perfectly but it is definitely fun to mess around with. This helicopter fits in the palm of your hand and is very light weight. The battery holds a pretty good charge. We are able to fly it around the house on a full charge for a good 20 minutes or so. Now, with this helicopter I also wanted something to practice landing.

    Good quality helicopter that provides hours of fun for kids and adults alike

    My 10 yr old loves remote controlled helicopters so when his birthday arrived a few weeks ago it was only natural for me to know what to get him....a new helicopter.

    SOLUTION for "toilet bowl" effect of a broken copter

    These copters are SO MUCH FUN. But the first two that I bought, after a few too many spectacular crashes, developed a crippling problem called the "toilet bowl effect." They lose their gyroscopic stability and start swirling around (as if they are in a flushing toilet bowl) in a way that makes them impossible to control.I googled this problem, and I tried a few things that DIDN'T work (it's not because lubrication is needed, or because the rotor shaft is loose, or because the balance bar is bent or needs to be replaced).The REAL reason for the problem is subtle breakage in a key part of the upper rotor assembly. It's not the balance bar that needs replacing, but a plastic molded part that is a point of common connection for the central rotor shaft, the upper pair of wings, and the balance bar. I've attached a photograph of the part and HOW IT BREAKS. That is, two tiny arms of the piece snap (the two broken parts are shown). It is very difficult to SEE... 4/5 I.

    Nice, light weight, very easy to fly!

    5/5 Maniac Reviews (Indiana) - See all my reviews This review is from: Syma S107/S107G R/C Helicopter *Colors Vary (Toy) The Syma Helicopter is very easy to fly! I was surprised at the fact I could keep it in the air without losing control or hitting a wall! I have mastered landing it on my Remote Control Helicopter Landing pad!Can be flown indoors or outdoors. When flying outdoors the wind may effect your flying as this helicopter is very light.Has red and blue lights that flash which allows you to fly at night, pair it with a remote control helicopter landing pad and you have the perfect set up for night flying.Flying time has ranged from 7 to 15 minutes for me, flying time is less outside depending on the breeze.Very easy to control, although I have yet to master what every button on the remote does! I just press the buttons, push the joys stick in every which direction and go! Flies like a dream for me!I received this item at a discounted price in exchange for my honest unbiased review., August 30, 2015

    Cool and Fun Helicopter Toy :)

    5/5 zhel21 (kansas,USA) - See all my reviews Verified Purchase(What's this?) This review is from: Syma S107/S107G R/C Helicopter *Colors Vary (Toy) The helicopter is one of the easier to fly, I've owned several and always enjoy flying them. The small size helps with indoor fun we try it outside but it didn't quite as good as indoor because of the wind and being open area. It has small blue and red LED lights in the nose which tells you if the power switch is on. The battery charges faster then most I've had before and lasts if not longer just as long. There's always an issue with any type of air flow that will make the helicopter react different. Just be aware of drafts and also flying next to things that create a draft from the thrust of the blades. The controller fits nice and has easy controls. Great gift for family and friends this coming Christmas. My son loves to watch it flying and trying to catch it. I am happy and satisfied with this helicopter! no complain so far.I received this Helicopter for free in sharing my honest and unbiased review! But it never affect my own opinion using this product!, October 5, 2015

    So much fun! My whole family loves to fly the helicopter!

    Customer Video Review Length:: 0:44 Mins My husband feels like a kid again with this helicopter. Opening the box brought him so much excitement. The helicopter looks so fancy and detailed. I was almost afraid to touch it. We quickly learned it is very durable and can take a crash landing or many crash landing really. We have two girls 3 and 1. They ask for daddy to take the helicopter out and fly it. They are memorized by how it moves. They do a great job getting it for daddy. The helicopter is very durable and they never even get close breaking it. I love bring it to the helicopter landing pad. It is a nice way of helping them know where it needs to go.To get started, we found the best thing to do is read the instructions. It may sound like a silly thing to say but super helpful. They give very easy to read instructions and it helps to get started. Especially since, my husband and I never owned something like this before.

    The difference between the S107 and the S107G

    5/5 B. Isbell (Chicago, IL, USA) - See all my reviews, May 29, 2012

    This is a really good helicopter

    I have been flying these minis off and on for over five years now. I have flown ones that cost $20 and ones that cost $200 and this is the best flying by far. The gyroscope is so precise that it feels like you are flying a computer simulation. There is almost no uncontrolled input like many of the cheap helis. The controls are basic with no roll but that's OK the pitch and yaw works just perfect. I also like the fact that the throttle/ up and down control is not spring loaded, it really helps when hovering. In all someone spent a lot of time flying and testing this helicopter before they marketed it. My only complaints with this thing is how difficult the battery is to replace. However for under $30 this thing is a dream, good job Syma. UPDATE: I have been flying this one helicopter for exactly one year now with no problems. The secret to long battery life is to keep it fully charged and fly the helicopter at least once per week, I have yet to replace the battery.

    It hangs a hard right every time while holding the joy stick steady

    1/5 Neily H. - See all my reviews Verified Purchase(What's this?) This review is from: Syma S107 3 Channel RC Helicopter with Gyro, Green (Toy) Unfortunately, this item was bought for my son's birthday present. I purchased it and once it was opened and used it was beyond the 'warranty' period per the seller. While I understand that it is beyond the 30 day return period, this item does not work. It hangs a hard right every time while holding the joy stick steady. My son is 11 years old and cried! I am surprised that this was so upsetting to him- but, it was his birthday. Regardless, please do NOT purchase this product. Our second helicopter purchased from another seller works well. (I purchased one for each of my son's and had to order from different sellers to get the colors I wanted). Perhaps if you feel that a 50/50 chance of working for the price and shipping is worth it to you, then go for it! But, I don't recommend this for a gift nor do I recommend this seller.

As soon as you get through the strangely complex packaging you get to find a screwdriver, OK, then you can open the battery door and put 6 batteries in! The action doesn't stop there though, after the batteries are in you get to watch your new flyer...charge for 30 minutes. But then...oh boy...time for the REAL FUN to begin. The copter goes up, careens into everything you own and crashes to the ground! Each time it does this you get to go pick it up and...reset it. AWESOME. After 3 or 4 crashes the fun begins again as the batteries die and the excitement of charging begins again.

    High Quality Syma Chinook Helicopter

    My husband has been trying out many different Syma helicopters lately. This is the first Chinook style he's flown. This one seemed to take a bit more getting used to. As soon as you would get it off the ground it would want to go forward instead of just up even when not using the forward or back controls. Takes a bit of getting used to but it definitely helps with hand/eye coordination. This Syma S026G definitely can take a beating though. It ran into walls, smashed into the corner of the television, and crashed to the floor multiple times and still got right back up to fly. That's what makes these totally worth it. It's great for a beginner or advanced flyer alike. My husband really enjoys the time he spends flying this around the living room and dining room and practicing his landing skills on his Eagle Pro Helipad which is available here:... 5/5 Melissa Anne (Nebraska) - See all my reviews Verified Purchase(What's this?)

    Great Little Quad Rotor Helicopter

    I own a Syma s107 and just had to try the Chinook for myself.What a great little machine! The trim is a little more complex than the 107 because of the front/rear drive concept but Syma have done a great job of making a potentially complex business very simple. A technological triumph.Trimming for spin is done as on the S107, with a knob set between the sticks. Trimming front/rear drift is done by clicking on the labelled buttons on the top of the transmitter. Couldn't be easier.Flight-wise the helicopter is very responsive and stable once trimmed. It has the typical gyro-stabilized contra-rotating design issue of the helicopter fighting its own forward/backward motion, resulting in this instance in a visible - but small - tendency to see-saw. As with the S107 the trick to fast forward flight with this design is to fly a serpentine path - by the time the gyro has "figured out" what the helicopter is doing and started to fight it, it isn't doing the... 5/5 Stephen Mann (NY, USA) - See all my reviews, February 24, 2012

    Flies great, but not for long...

    After reading the many positive reviews on this and other copters like it, I took the plunge and ordered some for my adult children as "stocking stuffers" this year. To maintain my alpha-male position, I ordered this one just so I could play too, and get a jump on them for expertise in flying. The good: 1) Very easy to fly and trim 2) Outstanding graphics and detail - comparable to HO trains. 3) Durability - has survived numerous crashes that always would have trashed the battery RC planes we have purchased. The plastic rotors seem impervious to hitting walls, coffee table etc. which is really a pleasant surprise. The bad: Flight time. Whether it is from having 2 rotors or just "the way it is", I get only ~2 minutes of real practice. After that, a few more flights are available with copter going up 5 or 6 feet, then settling down. Allows for "hopping" between places you want to practice landing, but then you have 30-60 minute wait until you can play again.
