The only comprehensive illustrated history of Frank N. Piasecki and
his H-21 advanced technology helicopter. The Piasecki H-21 became
the first successful tandem-rotor cargo helicopter to enter mass
production. Its innovative and unique design became the basis for
the development of both the CH-46 and CH-47 helicopters, which
remain in service to this day. The book covers the early life of
Frank N. Piasecki and the development of his first helicopter, the
single-rotor PV-2. Soon the XHRP-1 (Experimental, Helicopter,
Transport, Piasecki, Model One) would appear and it was this
helicopter which successfully demonstrated the feasibility of the
tandem-rotor helicopter design. Successive improvements soon led to
the HRP-1 and the more advanced HRP-2 which were flown by the US
Marine Corps and US Coast Guard. The US Air Force expressed a need
for a rescue helicopter that could operate in the extreme cold
environment of the Arctic and issued a request for proposal. Frank
Piasecki responded to this request with his H-21 tandem-rotor
helicopter design. The Air Force liked what it saw and soon the
H-21A "Workhorse" was in production for the US Air Force and the
Royal Canadian Air Force. The rapidly expanding US Army Aviation
Program saw the H-21 as a solution to meet its requirement for a
helicopter capable of carrying an infantry squad. Soon the H-21C,
now named "Shawnee" following the Army tradition of naming its
helicopters after American Indian Tribes. The H-21 was soon in
service with France, Germany, Sweden, Japan, and Burma. The H-21,
now know as the Vertol 44, entered civil airline service with New
York Airways. Five US Army helicopter companies, flying H-21
helicopters were deployed toVietnam during 1961-62. These
pioneering US Army helicopter companies proved that helicopters
were capable of operating successfully combat. This success soon
led to the rapid expansion and use of helicopters in Vietnam. The
Frank N. Piasecki and his H-21, both long overlooked, are
nevertheless true pioneers in the history of rotary-wing flight.
