Flown for the first time on June
29, 1962, the Do 32 E is an extremely simple folding helicopter which
can be transported in a small container: l=12ft 6in; w=2ft 9in;
h=3ft 3in. It can be assembled within five minutes and uses the
unfolded container as a take-off and landing platform. Compressed air
is supplied to rotor blade tip nozzles by a 90 ehp BMW 6012L
turbine-driven compressor. The jet stream from the turbine is
directed on to the vertical control surface, and all gears, clutches,
free wheeling units, shafts, and tail rotors are eliminated. Proposed
roles included observation and reconnaissance, and crop spraying and
dusting. A source states that a second prototype was seen at the
Paris Air Show 1963.
