In 1947, Hiller Aircraft developed the prototype Model 360X helicopter. A year later, on 14 October 1948 the Civil Aeronautics Authority (CAA) issued a production certificate for the Model 360. Hiller Aircraft began producing the Model 360 as the UH-12. In 1949, the UH-12 became the first helicopter to make a transcontinental flight from California to New York. When Hiller upgraded the engine and the rotor blades, the company designated the new model as the UH-12A. It was the UH-12A that would be adopted by both the French and United States militaries, as well as being used by civil commercial operators in several countries. The main rotor blades (produced by the Parsons Industries Inc.) are of solid wood laminations. The body of the blade is in fact essentially made up of numerous strip and block wooden laminations designed to provide a strong but highly flexible blade. The entire blade surface is covered with fiberglas cloth with the leading edge covered with an additional stainless steel sheet. The tail rotor is of all metal construction. |

Hubschrauber transkontinental von Kalifornien nach New York. Als Hiller den
Motor und die Rotorblätter aufrüstete, bezeichnete das Unternehmen das neue
Modell als UH-12A. Es war die UH-12A,
die sowohl von den französischen als auch von den US-amerikanischen
Streitkräften übernommen und von zivilen kommerziellen Betreibern in
mehreren Ländern eingesetzt werden sollte. |
