| Rare Genius Work by
Historic Technical Giants, it took a 10 year World Class
Program to get all the brilliance in their 83 year program
really correctly understood, and simplified. We
discovered Classic, Perfect Betz prop logic, Goldstein - Theodorsen essentially exact math. But, with no
math, the book teaches it all in understandable,
incisive insight. We learn the exact logic; the bottom line
of 142 years' historic work. We see, through easily
understood physical logic, the horse sense of what
- BGT Radial Blade Loading is Perfect.
A rotating wing is a thrust loss,
tip vortex loss Disaster. It's the core
problem that was never really, correctly grasped for
138 years, 1865 to the Wright’s 100th anniversary.
It's the Central Problem in Propeller Design
that understanding the Historic Rare Genius Work
Pulling in and throwing back air - Newton's
laws , hugely more massive flow rates than
An airscrew , teaches why a high
pitch prop is most efficient, both less induced loss,
and profile drag loss.
The classic, precise, optimum, minimum induced loss
"BGT" prop’s radial blade loading.
- The ideal family of optimally
SHAPED, loaded, pitched, twisted, all 6 way optimized props, minimum Induced, minimum
area, precisely placed; thus minimum drag, minimum
torque demand, minimum H.P. demand; thus MAX
THRUST, MAX efficiency!
Flying the IAS, Indicated Airspeed
that Maximizes IAS vs. Drag
, gets you 31.6% more
15% more Drag
than the Absolute Minimum.
But then, Climbing to the Max Possible Altitude holding

Plane and Engine are Perfectly, Optimally Matched,
If your plane Tops
Out at 12,500 feet, TAS/IAS is 1.21. Now, 1.316 x 1.21
= 1.59. You’re flying 59% faster for only
15% more Drag than the Min. Drag Possible, The
Thinking Man’s Way to Fly, The Engine at Low

Flight, the Flight Book becomes the Simple,
Insightful Pilot’s Aero 101 Course that you could
normally never find ! Basic Aero, Engines, all the
insight you could never find, everything in One
Double Book! It’s the Pro’s Lifetime of Insight,
the logic, all purposely “easy enough”, the insightful, understandable, horse sense of what’s
happening physically, the kind
insight we can all see through, and understand! -----------------------------------------
Written by The Technical Director, Mission Control, on the
Voyager World Flight, it is
the insight, and the
level of Insight that you could never normally find.
Before this, we never were going to have an explanation
of Propellers, and this book nails it all, understandably!
