The end of the 1950s was the start of a rich period for
the helicopter. Numerous technological breakthroughs
allowed this type of aircraft to set many records, some
of which still stand today.
1957
Sud Aviation bought the S-58 manufacturing license from Sikorsky. Between 1957 and 1962, 185 aircraft were built and improved upon, resulting in the H34 (used by the Army and Air Force) and the HSS1 (operated by the Navy).
28 February 1959
Maiden flight of the Alouette III. Specifically designed for flying at altitude, the Alouette III quickly acquired a reputation as a rescue
helicopter. Almost 2,000 aircraft were built – approximately 500 under
license.
14 September 1961
The BO103 performed
its maiden flight. This single-seater never
entered production because it had no
market outlet but the aircraft was used
to develop future Bölkow aircraft.
7 December 1962
The Super Frelon performed its maiden
flight. A few months later, this 13-metric ton aircraft, with
a rotor system based on American technology, broke three
speed records (all categories combined).
The BO46
performed its maiden flight.
Equipped with a hingeless
main rotor with composite
blades, and powered by
a French engine, this helicopter
was designed to reach speeds
of almost 400 km/h. Only two
prototypes have been produced.
Nevertheless the experience was very useful for
future helicopter technology developments.
15 April 1965
Maiden flight of the Puma. Designed
to meet the requirements of the French and British
armies, this helicopter had a new suspension system
for the rotor/gear box assembly, which would later
be used on all the helicopters of the range.
