Helicopter TheoryThe history of the helicopter may be traced back to the Chinese flying top (c. 400 B. C.) and to the work of Leonardo da Vinci, who sketched designs for a vertical flight machine utilizing a screw type propeller.

The history of the helicopter may be traced back to the Chinese flying top (c. 400 B.C.) and to the work of Leonardo da Vinci, who sketched designs for a vertical flight machine utilizing a screw-type propeller. In the late nineteenth century, Thomas Edison experimented with helicopter models, realizing that no such machine would be able to fly until the development of a sufficiently lightweight engine. When the internal combustion gasoline engine came on the scene around 1900, the stage was set for the real development of helicopter technology.
While this text provides a concise history of helicopter development, its true purpose is to provide the engineering analysis required to design a highly successful rotorcraft. Toward that end the book offers thorough, comprehensive coverage of the theory of helicopter flight: the elements of vertical flight, forward flight, performance, design, mathematics of rotating systems, rotary wing dynamics and aerodynamics, aeroelasticity, stability and control, stall, noise and more.
Wayne Johnson has worked for the U.S. Army and NASA at the Ames Research Center in California. Through his company Johnson Aeronautics, he is engaged in the development of software that is used throughout the world for the analysis of rotorcraft. In this book, Dr. Johnson has compiled a monumental resource that is essential reading for any student or aeronautical engineer interested in the design and development of vertical-flight aircraft.

Great product.

This worked perfectly in my vehicle making hands free driving easy. Installation was very simple, easy to charge my phone in this mount. Very stable, my phone never fell out or off.

Almost perfect
Style: Screen+Charger
Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Super easy to set up
Style: Screen+Charger, Style: Screen+Charger
I couldn’t be happier with this car phone mount—it’s easily one of the best accessories I’ve added to my vehicle. The build quality feels solid and durable, with a strong grip that keeps my phone securely in place even on bumpy roads. Installation was quick and hassle-free, and it holds firmly without slipping or needing constant readjustment. What really stands out is how easy it is to use one-handed. I can mount or remove my phone in seconds, which makes a big difference while driving. The adjustable viewing angles are perfect for navigation, and it doesn’t block my view of the road at all.

Poor socket design.
Style: Holder+Dash+Vent+Windshield
Overall this is a pretty decent phone mount. I have used it with both the windshield and vent mounts. The only problem I have is the design of the ball swivel. The socket contains a rubber piece to help increase the grip, but over time heat from the sun or the air vent makes the ball glue itself to this rubber piece. When you try to make an adjustment, the ball will not move in the socket and ends up breaking the socket. This is happened to me twice.

Great Phone Holder
Style: Holder+Dash+Vent+Windshield
I bought the version with the suction cup mount and I’m very happy with it. It holds my phone securely in place and doesn’t move around while driving. It’s also very easy to place the phone in the holder and remove it when needed. The suction cup sticks well to the dashboard, and you can position it so the phone stays in a safe, easy-to-see spot while driving. Overall, a great and reliable phone mount. Highly recommend!
