Hoyt A. Stearns Jr.: Some Historical photos I took.

Email me:  hoyt-stearns@cox.net

I befriended Dr. Bruno Nagler when he watched me learning to fly my single seat Scorpion helicopter without instruction.
He was a helicopter pioneer, and was actively promoting the concept of the torqueless helicopter, where the blades are powered
by compressed air blowing out the blade tips.  Those types of helicopters are very much simpler and safer than conventional helicopters.
(see the video linked below).   A while after he died in 1979, and seeing no further activities in the field, I worked to continue his dream,
resulting in two US  patents (4,702,437, 4,720.059 ).  The first was to improve the efficiency of the concept by putting electrically powered
cross flow fans inside the blades.  The second was a way, using an offset flapping hub to obtain much higher speeds by unloading the retreating blade,
using the moment on the hub to offset the lift differential between the advancing and retreating blades.

Historical photos I took of Bruno Nagler and prototypes etc. at Nagler Aircraft Co., at the end of this page,  B.J.Schramm, Phoenix, Arizona about 1974.
