Looping Of Pca Autogiro

On October I3, 1931, at approximately S P.M

Mr. D. W. Dean looped the PCA-2 Autogiro No. B-15 ttri.ee. 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 the two loops, as at the completion of each there seemed to be a tendency to fall out to the right; while others agree that the second loop was the best.

Mr. Dean's speed as he went into each loop was 120 M.P.H. Ke did not obtain his rotor R.P.M. during the loop, but in a tight turn he accelerated the rotor to l8o R.P.M.

The looping of an Autogiro, which has been considered as theoretically possible as long as the loop -was clean, has now been practically demonstrated.

Several pilots looped the autogiro. John Miller performed bopsevery day with the American Ajr AcesShaiw in the mid thirties. Charlie Otto who fleu' advertising fanners for Lee Tire and Rubber Company looped his PCA-2 in the thirties.

A report was found in the Pitcairn archives and says a pilot, D. IV, Dean, looped a PCA-2 at thePitcairn factory on

October 13, 1931.
