- Total Flight Time
- 2400+ in rotorcraft
I think you might have not read my original post or I may have not articulated it well.
Would you agree that the gyro flys through relative wind and as long as there is wind going through the rotor the gyro does not know the earth is below it or in front of it.
Would you agree the the rotor is tilted back about 9 degrees typically do that the relative wind can spin the rotors?
So if you were in a dive- not a glide- dive dive dive! Lol
And you are let’s say max power max speed a setting that would be fastest available speed in level flight-
Are you still going to climb out of that dive?
I am unable to understand what you are trying to articulate.
The answer to the first question is no; I would not agree that a gyroplane rotor disk is tilted back about nine degrees to the relative wind.
A rotor disk on a gyroplane at near VNE is tilted back just a few degrees to the relative wind.
At very low indicated air speeds the rotor disk may be tilted back as much as fifteen degrees to the relative wind.
Gyroplanes have a power required curve and above or below the minimum power required speed the power required to maintain level flight is increased.
If the power required exceeds the power available the gyroplane will descend even at wide open throttle.
There have been many gyroplane accidents because people did not understand this and imagined a gyroplane climbs with the cyclic.
The control of the cyclic is done with pressure rather than movement and the gyroplane I train in, The Predator will run along nicely level at ninety knots at full power with the cyclic against the forward stop.
The first picture is The Predator at eighty five knots indicated air speed, the second is rounding out with at around twenty five knots indicated air speed and the final picture is touching down at less than five knots of indicated air speed.
