Title: climb rate and angle of bank
Post by: lulu on January 15, 2011, 08:33:36 PM
Situation:

P51 level flight and choose an angle of bank.

At which angle of bank your p51 climb rate starts to decrease?


And f4ux? And your spit?

Trick question.... if you're in level flight, you're not climbing. If you bank to a certain degree, you will start to lose altitude unless you counter with other control inputs.    :bolt:

a good overall way to keep energy up is keep in under 2K feet a min, works for all fighters.

At 0.000000000000001°. When you bank some of the lift provided by your wing starts being used to turn you, not lift you. If you want the best climb rate keep the wings level.



Did I understand your question correctly?

I found different behavior between spit, pony and f4u for the same angles of bank A.

For example :

Angle of banks                       airplane                         Climb

   10                                     spit                              Fixed

   10                                     p51                        decreasing very fast

   10                                    f4u(A or D)               decreasing gently

   >10                                   spit                         decrasing

    .
    .
    .


Is this a problem as I suspect?

Neg,

I don't looking for a best climb rate.

I want not to compensate my wing if their angle of banks is not the PROPER ONE - If it exits.

A plane's lift is designed to go straight up. If you're in trimmed level flight at a constant speed and you roll the plane any number of degrees, the lift is no longer taking you straight up. Keeping the trim the same and leaving the stick centered, your nose is going to go down because your lift is not being used to directly counteract gravity anymore.


Hope that helps.

Simple: You get maximum angle of bank (Always less than 90degrees) for maximum angle of attack (thus maximum G loading). To get such G load, you need the speed at which you airplane gets the maximum turn rate or critical wing loading/pilot blackout is a limiting factor.

Basically climb rate will be negative in a level turn when the vertical component of the plane's lift vector is less than that of its weight at any bank angle.

Assuming you meant wing's level instead of level flight, ANY angle of bank other then 0 will cause a decrease in climb rate.
