Variable Pitch Prop on T/o Roll
Hi,
I was going through propellers in Oxford Principles of Flight and it says on Take off roll:-
As the aircraft continues to accelerate the TAS will increase, which decreases the angle of attack of the blades. Less thrust will be generated and less
propeller torque. This gives less resistance for the engine to overcome and RPM would tend to increase.
I get it up till less thrust but why will the prop torque lessen??
And if the torque lessens then why does the RPM Increase? is it because of lesser torque opposing the engines torque?
Thanks for the Patience guys!!
