Engineers
The rotor problems were worked out by people who drew them, machined them and then flew them. Juan de la Cierva published as he went; the drawing offices and the test fields around him are where the arguments were settled.
Juan de la Cierva
The engineer whose successive machines worked through the rotor problems one at a time, and who published as he went.
The drawing office
Rotor work is geometry before it is anything else, and the drawings are where the argument was conducted.
Test flying
Each change had to be flown, usually by the people who designed it.
