Slats - We need 'em!

[funkedup]

AH has no leading edge slats on the planes that had them (Me 109, La-5FN, La-7).  And the Me 262 (rumoured for AH 1.08) had slats too.  Wouldn't 1.08 be a perfect time to add the slats to the graphic and physical models?

Also there are some flap issues.  The inboard portion of the Me 109 flaps should have radiator exhaust through seperate upper and lower surfaces.  N1K2-J should have fowler flaps, and they should be automatically deployed.  There are probably other flap details I don't know about too.

After that they can work on the minutia.
Trim tabs, balance tabs (e.g. F4U), cowl flaps (e.g. P-47), radiator exit doors (e.g. P-51).

You may not see the slats on the 109 but HiTech or Pyro said a loOong time ago the effect of them is. No idea about the others.
 I'd love to see them visually and hear audibly however on the 109.

Me too oops...!

Westy I think you are correct.  I think I remember an HTC statement that the slats were included in the lift and drag curves for the airfoils.  I'd still like to see them in the 3d models, and also see a physical model of the actuation dynamics.  That would change the handling of the planes a little bit.

yes yes funky preach on preach on

[Zigrat]

if they are modeled i certainly dont feel them

i have never felt any snatching in slow turn in a 109 under sideslip, as would be the case if slats were modeled

Then I remember post in which they algien said that the Slat's was not in the 109 by the difficulty that is to make the physical calculations of behavior, I do not believe that the 109 of AH take Slat's. I want that HT or Pyro confirm or deny these points and we leave ourselves of polemicas. he is but the facil thing, that us says they to it.

I suspect they are not modelled on the Lavochkins in terms of their delay of stall onset.

The pilots guide advises a landing speed on the la7 & la5 equivilent to about 85 miles per hour.

This is near impossible in AH.

Some test notes I have indicate that the slats should deploy fully at about 200/220 km/hour IAS. (Presumably level flight)

Thus opening at 125mph IAS one might expect an element of stability down to 100 (at least) without flaps and certainly down to 80 (if not 70) with varying degrees of flap. Unfortunately this is only an opinion.

The La had an infamous reputation for rapid departure from the flight envelope. (although fairly simple /easy spin recovery given sufficient altitude)This is almost certainly atributable to the effect the slats have on the envelope and the fact that they were not along the full length of the wing (outer half/third). Hence we may expect a "snatching" high speed stall (when ruddering around a dipped wing) in comparison to the more mushy departure characturistic of the 109.

AH does model this some what but IMHO could make it even more violent but at a lower airspeed.

I have "fondled" the La7 slats on White 77 at Kebly Prague.

 

 

They are quite friction less. The vacuum pot is counter balanced to provide a smooth transition from closed to open with very little force required. I would be surprised if they were to open quickly with a thud (as if pushed past some threshold)or any sound that the pilot would be aware of. I would expect then to respond directly in proportion to the air pressure at the leading edge of the wing.
