Bristol Model 171 Sycamore
- In 1944 the Bristol Aeroplane Co formed
a helicopter division
under well-known helicopter engineer Raoul Hafner.
The first product
from this division was the Model 171 Sycamore which
first flew in 1947.
178 examples had been built when production ended
in 1959, mostly
for military operators, seeing service in Germany,
Belgium and Australia
as well as the British Army and RAF.
Bristol Model 192 Belvedere
- The first British tandem-rotor helicopter,
the initial Bristol
Model 173 basically combined two sets of Sycamore
rotors and controls
interconnected by a shaft to protect against engine
failure. The prototype
first flew in 1952 but encountered considerable
development problems.
A production model using Gazelle turbo-shaft
engines was designated
Type 192 and the prototype for this version
first flew in 1958.
The first of 26 examples for the RAF entered service
in 1961 and the
RAF remained the sole operator of the type.
