Corsair vs. BF 109G,K or FW 190's

Aerodynamically, gliders and the Ta-152 do both have high aspect ratio wings and beside other things follow the same principles. I second Gliders experiences.

[Crumpp]

Just because you're at altitude at 700 km/h doesn't mean you're pulling 3 or 4 Gs.

To give the readers an idea of the effects on the Ta-152, critical mach for the NACA 23015.3 is ~ mach .655 in level flight.

Changing this to CLmax drops our critical mach to ~mach .5.

So at a velocity of 700kph at 33,000 feet we are just a fraction below the critical mach but our maneuvering is limited.

Of course everyone understands that all aircraft are effected by this not just the Ta-152. Airfoil choice will determine the critical Mach number.

Our High Aspect Ratio wings on the Ta-152 will do much better when the equivalent airspeed drops to the low velocity realm than a Lower Aspect ratio wing on the same design.

A short Aspect ratio wing is optimized for high velocity equivalent airspeeds and will not do well at all at high altitude because of mach limits in comparison.

All the best,

Crumpp

Crumpp,

We agree completely.

And no worries, you didn't come across as a know it all or as trying to talk down to me in any way, so no need for any apologies.

Glider,

Many apologies, I didn't know you went up there all by yourself, kudos to that!

Hope that eased the bruising

The wife has told me to quit sulking. No worries.

[Soren]

Wives can be so strict!

Crumpp,

How much into jet-propulsion are you ? Would you be able to produce a similar chart for the Me-262 sometime in the future ?

Thrust producer theory is a standard part of the curriculum for the degree Soren.

I would have to modify or create a new spreadsheet but it can be done.

I really haven't had anytime to even look at combining the charts or use Henning's program.

It's Christmas time, annual time, and airplane insurance time at my house.

All the best,

Roger that Crumpp, I understand completely, a very busy time for me too.

Merry Christmas !
