The
helicopters to advance towards ahead need to incline the plan of the
main rotor under the horizontal, to create one quite that
promotes towards ahead taking the air
of above to down
with the help of an engine to the main rotor. It would not be possible
to make a helicopter for flight free. However the autogiros fly
normally with the plan of the rotor with an angle above the horizontal
so that the one that sustains the movement of the blades is the air
that hits under the rotor. It is necessary to say that the helicopters
have a security system that in the event of stop of engine disconnects
the main transmission,
it invests
the angle of incidence of the blades (without investing the sense of the rotation) and it makes
enter in autorotation allowing a safety landing.
Autogiros
for free flight
Is the observation of the functioning of the light
aircraft autogiros at the beginning of the 90, in particular of the
model
Mach-10 of Sallén
Aviación the one that led me to be thought that...
because not to eliminate the engine and frame and replace it
for a triangle and a keel of delta wing?. Its known that the advantage
of the light aircraft autogiro it is that in the event of stop of
engine they continue in selfrotation, as a matter of fact, with the
engine at minimum power
him almost as if they did not have propulsion. So the idea about a
autogiro of free flight appears with relative naturalness.
