It will be interesting to see how well Flugwerk's Dora-9 does when it gets up and flying soonI'd take that bird to every Mustang show in the world with full confidence !
Like I've indicated before, your confidence would sorely misplaced if a P-51H showed up.
Nope, it wouldn't, and esp. not if my Dora's got GM-1, a D-12 prop and wheel doors, cause then I'd smoke any P-51 in a heartbeat.
You nor anybody else has supported that statement with data concerning the P-51H vs. the Ta 154, much less the Fw-190D-9. I heard rumors but nobody anted up. In fact, I suspect that you cannot justify that statement with data about the D-9 in comparison to the P-51B using fuel available when the Dora was flying. Show me the stats relative to speed, climb rate, time to climb, power to weight, wing loading, or anything other measurment that would support your argument. Of course the planes would have to be equally matched in fuel and weapons load. I can be open minded and my opinion can be changed. As of what I have seen, the P-51H clearly superior to the P-51D and Ta 152H (below 30k ft), and would certainly be more than competitive with the best German, Italian, or Japanese had to offer (not including jets or rockets).
Adler and Erich,
davparlr,
Instead of looking at that calculated chart why don't you take a look at what the P-51H 'really' could;
453 mph at 21,000 ft and 4,700 ft/min at sea level, 30,000 ft reached in 9½ min:
This certainly has me puzzled. The charts have been recently updated and looks good but the previous charts showed the same values but the writeup stated that the water injection was not working. Also, this is quite a difference to the engineering data which was calculated but correlated to flight test data. This would indicate a large error somewhere. However, flight test data identifing an airframe is the best data.
Okay, lets go with what you have. The best data I could find on the Fw-190D-9 was airspeed of 440mph, ceiling 39K (?) initial climb rate of 3300 ft/min, and going to 6000 meters in 7.1 minutes. So, unless you have flight test data to counter this, it seems that the P-51H is still faster (453 mph), has a higher ceiling (41K), has a higher initial climb rate 4600 ft/min and better time to 18000 ft. (between 3 and 4.5 minutes). Also, power to weight and wingloading at equivalent fuel and ammo would benefit the P-51H. And, if you look at the flight test data for the P-51B climb below (also it is in the same speed range but wouldn't have the power to weight and wing loading advantage the P-51H has), it would even beat the rather lazy Dora. This flight test data, so you'll have to show me the same level of data that would indicate superior performance. If you can't, I don't know where you would get your confidence. You'd be facing faster, faster climbing, higher climbing, with better power and wing loading aircraft. You must be a heck of a flyer to be so confident. So, give me your data and convert me.
Also, if the P-51H data holds up (it looks good), I would reassess my comments in comparision to the Ta-152H.
davparlr,
The chart you posted is a calculated one made in September 1944, and as evident they were VERY over-positive about suspected performance !
The charts I posted are based on real test-flights with a clean aircraft conducted in october 1946.
And forget about wing-loading davparlr, cause the P-51 used a laminar flow wing design (Root = NACA 66-( 1.8 )15.5 Tip = NACA 66-( 1.8 )12 ) which in turn didn't produce nearly as much lift pr. area as a conventional wing design esp. in tight turns - A Laminar flow wing will stall earlier and more violently than a conventional wing.
Note: The effects a laminar flow wing has on turn performance in particular can be seen in the AFDU comparison between the Hawker Typhoon and Tempest.
Now about FW-190 Dora performance, I'm going to make this as clear as possible this time (For the millionth time !)
Based on test-flights;
