Pitcairn-Cierva PCA-2

pitc-pca2


1928 found Cierva giving demonstrations of the O-19 and selling the manufacturing rights to representatives from around the world. The American rights were purchased by Harold Pitcairn who made a few design changes but retained the basic design principles and features found on Cierva's machine.

Pitcairn used a more modern fuselage with better aerodynamic qualities for his PCA-2 gyroplane, and offered two engines for use in the aircraft. Both were radial aircraft engines mounted in the usual tractor configuration: the first produced 300 horsepower, the second, 420hp. Pitcarin also utilized a four-bladed rotor system with Civerva's flapping hinge. It innovated with a clutched gearbox that briefly transmitted power to prerotate the rotor to greatly shorten the takeoff run.

Pitcairn produced and sold 24 of his PCA-2 gyroplanes over the next few years. They showed the versatility and practicality they had been designed for by carrying the mail over a federally contracted route, being used to reach the scene of the news and for aerial photography by the "Detroit News" daily newspaper, and by setting new world records. Amelia Earhart flew a PCA-2 to the record altitude of 18,415 feet over Willow Grove, Pennsylvania on April 8, 1931.
