Tips causes no torque, eliminating the need for an anti-torque rotor. Rocket drive is expensive to operate but no transmission is needed, so the system possibly could be built quite a bit cheaper. Planned flight experiments never came off. The autogiro was donated to Princeton University's For re stall Research Center. Princeton University never flew it. About 1959, it was sold to one of their mechanics who assembled it and John Miller, one of Kellett's former test pilots, flew it. Later it was...

On one side of the rotating circle and decreased on the other. Juan de la Cierva was a structural engineer and had in the past designed trusses for bridges that were pinned at the ends to permit motion at the ends to relieve bending, Cierva never said that he invented something or that he discovered something. He said, God permitted (him) to know something. He applied the bridge design principle to the autogiro rotor blade attachment at the hub. The pin at the hub permitted the blade to flap or...

The change in the rotor pylon from four legs to three legs, elimination of the outboard flying and landing brace wires on the wings, and a slightly shorter landing gear. The fuselage construction was welded steel tubes of varying diameters and wall thicknesses. The aluminum tubing fuselage on the PCA-1 was abandoned because of the difficulty of repair. The longerons on the PCA-2 were the familiar square shape that Pitcairn had used on all the Mailwing airplanes. The forward part of the fuselage...

He says that on his first loop he thought he pulled the stick back too sharply, causing it to fall out of the last part of the maneuver, while the second one was a clean, normal loop. He said that the Autogiro felt no different from an airplane, while he was going through these loops. Some observers from the ground apparently disagree, saying that they could observe very little difference in...
