Spit/109 sea level speed comparisons in 1.08 beta patch

The prob with the wider LE was IMOHO with the prop wash that in certain situation (yaw) prevented one slat to fully open. Having yaw angle is fairly comune during a DF unless you stay focused on your slip angle.

~S!

This is not correct, when the aircraft is pulling tight turns the g load on the slats makes them snap open, they are designed only to open gently at slow speeds for landing and take off.

The leading edge slats of the 109 work through air pressure distribution and this is depending on the angle of attack. The slats deploy gradually over a small range of the angle of attack, making it possible for them to snap open in abrupt manoeuvres, but they can also be made deploy gradually when increasing angle of attack gently.

The leading edge slats were reworked with the F series in that their span was reduced and the mechanism simplified. I don't think the deployment was changed a lot.

In my mind Kurfurst is the person for this, but what isn't in question is that they were redesigned for the 109F

Given what Rall said below, would you not say that the "embarassed" remark was fair comment?

No.

Here is handley page automatic slats in operation on my old airplane:

Unless they are new to you, the slats are nothing of note as far as piloting goes.

What do for the airplane is outstanding. You can pull some insane body angles with them.

Here is another video I made on the way to work. It was beautiful day to fly.

Pilot notes to a whole new level

Since you asked, yes intro flights are probably much more expensive in the UK than in the US, if you want to fly with me in a Stearman it will cost about £360 per hour, I don't remember what we charge for the 152's or warriors but it's around £150 per hour.

Heres the vid of me and fruitbat in a Stearman taken from that GoPro camera on my head in my avatar pic, check 14:30 for the 'hello Crumpp' and 17:30 for some basic aero's.

Heres a vid of me flying the Learjet, 2008 fresh back from Dallas and doing my 6 cirquits to finish the type rating.

Very cool. Here's me and Riley squished in a Spit cockpit.....

Sigh........sayin' nuffin.

Crumpp, you need to take some drawings lessons

There is a reason why I am not a commercial artist, LOL.

Here is picture of my hanger, these are my planes....sole ownership....

Means you are alone on the bills too!



Both are fully aerobatic but the Thorp is not a good platform for it. It is too slick and you really have to pay attention to your speeds when you point the nose down.

The Thorp is a good cheap, fast, and fun to fly cross country machine. It has a Lycoming O-360 with a Hartzell CSP. It is IFR, four place, and a traveling machine.

The Extra 300 is my sky cutter. It has a Lycoming IO-540 with an MT propeller.

Back to the thread....

Looking at all the data and trying to pick averages staying away from either extreme using both Supermarines and Mtt data......

This is the relative turn performance of these two aircraft taking as much data from the Operating Notes and Flugzeug Handbuch.



Here is a Rate of Turn comparison. Rate of turn is the most important aspect of turn performance as it represents how fast the aircraft can swing its guns thru the compass to bear on a target.



Hope it helps!

Crumpp..Nice barn! but too small
