helicopter silly questions
hello folks
here i am again with a couple of not so clever questions, even though there is not such a thing as a stupid question in the aviation world!
just bear in mind that even though i have experience on fixed wing airplanes, i do not have any experience on helicopters, just a fascination with them.
Why is the downwash produced considering that the high pressure is on the lower side of the rotor disk and the lower pressure on the upper portion?
In a counterclockwise main rotor system, the sideway thrust generated by the tail rotor is oriented to the right swinging the helicopter to the left about its pivoting point to counteract the torque effect that makes the fuselage to spin clockwise?
Why do you have a yellow arc and a red line on the MAP gauge? is that due to prevent overboosting or does it have any aerodynamic implication?
what is the difference between the freewheel unit and the sprang clutch and is there a sprang clutch in the r22?
are the blades on the r22 and 44 symmetrycal or asymmetrycal?
Many thanks and more silly questions to come!!
