The XRG-65 Glaticopter, developed by
Edward W. Glatifelter of Galaxie
Engineering Company, Newton Square,
PA is a one-man research helicopter
intended to evaluate new ideas in
rotor control and drive systems.
The main rotor is a two-bladed,
teetering type using a large
universal joint as center.
Cyclic pitch is effected indirectly
by use of a servo-rotor consisting
of two servo blades arranged at 90
degrees to the main blades.
Both main and tail rotors are driven
by multiple V-belt drives. The
fuselage is of welded steel tube
construction, and the main rotor
blades are Fiberdyne tapered,
non-linearly twisted featuring the
fail-safe root end
"wrap-around-a-fitting" principle.
Powered by a 65 HP Continental A-65
engine, the XRG-65 employs a number
of specialized components from
unique sources and was first flown
in 1959. Flight testing
continued through 1963, Only
one aircraft was ever built and
flown.
