Charles H. Kaman, pioneering designer of both helicopters and guitars, died at his home in Bloomfield, Connecticut 31 January. He was 91.
Kaman was a 26-year-old engineer when he founded Kaman Aircraft Company in 1945 with $2,000 from two friends. First based in the garage of his mother's West Hartford, Connecticut home, Kaman set out to demonstrate a new rotor concept he devised to make helicopters more stable and easier to fly. His idea was based on "servo-flaps" -- small ailerons added to the edges of the rotor blades to improve stability. He also proposed intermeshing rotors, which would increase lift while eliminating the tail rotor.
