Thanks now I understand why Dash 8 propellers (twin engine) are always feathered at rest. I thought it would be easier to start up if they were 90°
@firstlt2 4 жыл бұрын
For Turboprops it gets even more complicated. The Dash 8 uses a free turbine to drive the propeller, apparently this is why the blades are flat when the engine is shut down. On the other hand, geared Turboprops use a gearbox to transmit the power, Garrett engines like on a Jetstream 32. These blades have locks which keep the blades at fine pitch for engine starting.

Would be interesting to know about the relationship between manifold pressure and prop rpm. When I decrease the rpm, the propeller is harder to turn so the load on the engine goes up and so does manifold pressure? Or am I missing something here? :)
@OldCarsAreFun 4 жыл бұрын
Manifold pressure is the vacuum between throttle and the cyclinders. Closed throttle is more vacuum. Increased throttle, the pressure returns more to atmospheric pressure. With more load, pressure will increase because you need more air/fuel

Can someone explain the propeller vs. engine torque and its relation? I dont get how an increase in propellers pitch (and with that a decrease of the props RPM) increases the propellers torque...
@keksimusultimus4257 3 жыл бұрын
torque is basically the "drag" you create by generating Lift with the propeller. that's the simpliest form you can get as an explanation.
@dennisrkb 5 жыл бұрын
so do you fly at full throttle with such a prop?
@threestrikes1448 5 жыл бұрын
I wonder if jet engine will change the pitch too...
@mindeloman 5 жыл бұрын
Probably a better analogy is not a conventional automotive automatic transmission, but a CVT transmission or constant velocity. The engine RPMs stay constant while the hydraulically controlled transmission pulleys adjust to the load and speed demands. This is why you feel no shift shock on a CVT.
@Keyboard_Flight_Academy 5 жыл бұрын
No, the purpose of an analogy is to compare a foreign concept to something everyone already knows. Whatever you're talking about is comparing a foreign concept to another foreign concept. Your explanation means nothing to a beginner. However, the basics of a car transmission makes sense to someone who has never even been in the cockpit.

Great explaination! I have a hard time figuring out how this "modern" propeller-technology works, but i got a better understanding of the mechanics... Why cant we all just use regular jet engines instead of turboprop and piston engines?

simple: economy and efficiency. Props are very efficient at low speeds, below 300kts. Above that, jet engines shine, especially when the ram-effect at the intake takes place.
@airistoneo 7 жыл бұрын
So, when taking off the prop angle is closer to 90 degrees to the ground and once altitude is reached the prop angle is changed towards 45 degrees to take a bigger bite out of thinner air. This keeps the aircraft in the power envelope more optimally. Is that right?

mr. idoit as an airline pilot you don’t need to know this information anymore. It’s good information yes, but not necessary to be flying airliners. Also, remember this was 65 years ago and I don’t think constant speed props were a thing yet.
