1-1 1-13 Helicopter took a long time to develop, giving me a chance to catch up with the competition. New ideas in radio would quickly show up in the magazines. Helicopter
Radio days
The question is why did I take up the helicoper rather than something else.
1-2 4-54 Using medium size models was an expensive and time consuming process but allowed the study of stresses. Meeting Sikorsky at Rotary Wing meeting. Sikorsky’s reasons for using the tail rotor. I always assumed that the models would fly. Small models allowed for flight testing. The teaching value of crack ups. Helicopter
Model building
Igor Sikorsky
Flight testing
The power of model building I did not fully appreciate until later.
1-3 4-23 Attempting to use a pendulum to regulate the rotor. The stabilizer bar can distinguish between acceleration and gravity – it uses an artificial horizon. It uses the absolute nature of rotation. In general, stabilization can only be achieved with reference to the universe. The local situation won’t suffice. Helicopter
Stabilization
Pendulum
Stabilizer Bar
Rotation
As the helicopter took off
1-4 1-00 Model building is like the scientific method of trial and error. Model building
Scientific method
The model building process is very sacred to me now.
1-5* 2-30 With a helicopter rotor, control is at right angles to the direction you want to go. This played a large role in developing the theory of meaning. The meaning of any opposition is at right angles to the opposition. Helicopter Rotor
Control
Right Angle
Meaning
Physical/Mental
The helicopter rotor -- looking down on it you can think of it as a circle.
1-6 2-22 Cybernetic control involves stability. Fugoid oscillation due to proper feedback. Positive feedback leads to catastrophic instability. Cybernetics
Stability
Feedback
As I said at that cybernetics conference…
1-7 2-30 Development of the helicopter as an example of a seven stage process. The Stages
Helicopter
My first thing was "the sky’s the limit" kind of thing
1-8 6-08 Story of the first demonstration of the helicopter model for Bell. Meeting Larry Bell. Bart Kelly and AY were installed in Bob Woods’ office. Other anecdotes from first days at Bell. Helicopter
Anecdotes
Arrival at Bell
I arrived at Bell on the morning of September 3…
1-9 2-52 Initial days at Bell. First plan was to make drawings. AY convinced them to shift budget to build a working model – provided the engineering dept. had nothing to do with it. Helicopter
Anecdotes
Bell
I thought that when I arrived at Bell the engineers and experts in various subjects would immediately start building this full scale helicopter.
1-10* 3-35 The problems with the production line. It took less time for a team to assemble a machine than for it to be done on an assembly line. Story of the attempt to modify the bearings has implications for evolutionary theory. Helicopter
Bell
Production
Evolution
We didn’t try to solve the production problems.
