Re: Aircraft performance curves
No, Graham, these graphs shouldn't should be completely discarded. As I said, I don't say that aircraft performance curves is totally superfluous, but it requires technical knowledge to be able to use those curves properly, and I find it surprising that no one of those who have such high thoughts about their own technical knowledge have discussed the weaknesses of these ordinary performance curves.
Also, for what do we need to know a Hs 129 ground attack aircraft's different average level flight top speeds at clinic tests at 17,000 ft, 22,000 ft, 24,000 ft, and 28,000 ft respectively? I am always out looking for good WW II combat aircraft data, and would love to learn e.g. which is the source to the Bf 109 F-2 performance curves which Franek has access to. |

Re: Aircraft performance curves
Sorry for "bumping", but maybe Jukka and Franek missed my questions?

Re: Aircraft performance curves
Hello Christer
I'm not Jukka but where he demanded different average level flight top speeds at clinic tests at 17,000 ft, 22,000 ft, 24,000 ft, and 28,000 ft respectively for Hs 129? I even checked the locked book thread and Jukka never asked that. He missed performance graphs, so why to misrepresent his oppinion. IMO You are playing a cheap trick, in fact stupid old propaganda trick. Why???????????????? I cannot say that I'm surprised but Juha |

Re: Aircraft performance curves
Juha, maybe I misunderstood Jukka. Okay? I was curious just for what we need performance curves for a ground-attack plane like the Hs 129. If you can't explain that, then please allow Jukka to do that.
Gizmo, I'd be grateful if you could send me a scan of those Bf 109 F-1 & F-2 curves in an e-mail. Quote:
(BTW, it's "Flugzeugmuster") |

Re: Aircraft performance curves
I believe that Jukka is looking for more technical data in aircraft books: to restrict this wish to the simpler performance curves is to misrepresent his argument. There is much more to be said about an aircraft's technical side than just the performance terms.
However: given the level speed it would be possible to calculate the drag co-efficient. From this other performance data can be calculated. For example, payload-range, turn radii and accelerations that would be of interest to almost any combat type. It would be possible make much realistic comparisons than can be found in anecdotes, usually from the winners. |
