Trivial Pursuit
Please tell me so that i am not going mad a nice explanation of "P" factor and why it is called pee factor asymmetric blade effect one and the same...?????
And a definition of a critical engine ???. just done my painful grade II on the twin, passed but with a steaming disussion for my twin lecture on these two easy.... - well it didn't seem like it at the time, any offers would be greatly appreciated. finally anyone know the word "tristadecaphobia" I got it when we were playing trivial pursuits the other night- never heard of it in my life mate! thankyou :D :D :D :D :D :D :D :cool: |
P factor - Descending blade has a greater angle of attack and thus creates more thrust then the ascending blade - especially at high (wing) angles of attack. Thus with a standard clockwise (from cockpit) rotating (right-turning) prop you tend to get a left yawing tendency in the climb.
P maybe stands for Propellor, I'm not sure. Critical engine - That engine which if fails will cause the most adverse reduction in controllability. On a standard twin it will be the left engine, on counter-rotating twins (PA34/PA44 etc.) there is no critical engine. Tristadecaphobia - not a clue. Hope this helps a bit. |
triskaidekaphobia - fear of the number thirteen
pilot-lite |
dean,
Re. p-factor - see if you can borrow a copy of "The Compleat Taildragger Pilot" by the late Harvey S Plourde, ISBN 0-9639137-0-0, published privately by his family. There's an appendix which gives a very deatailed mathematical explaination of p-factor - far more detailed than you'd need as a pilot, but it'll answer any questions you've got as long as you can fight your way through the maths!

P - position of centre of thrust

What I can´t work out is how you can be excessively afraid of knees and roses..
Or even beeing afraid of beeing afraid, could work out quite nicely if you are very polite: I´m afraid that I´m afraid of beeing afraid.. :D :D |
Would that be a phobiomaniac or a maniophobic?

“P” Factor or Propeller factor: This is the way they taught it when I went through mechanics school way back in 49. The airflow from the propeller is in the form of a vortex, which can impart a sideward force on the vertical fin. To counter this force the vertical fin is offset somewhat generating an aerodynamic force that counters the sideward force generated by the vortex.

phobophobia :D |
You are describing slipstream effect there Lu, not P factor.
