Reggiane RE-2007 - What if?

[DAVIDICUS]

A drawing from the design boards of the Re-2007

oh god if CC reads this he's gonna claim that the designers of the F-86 copied the italains an he'll try and use the fact that the F-86 was so goo dto claim the RE-2007 would have been amazing and i'll get really annoyed.........

thans for pointing that out guys........

Aircraft designers often arrive at similar solutions to the same problems, so their aircraft look decidedly similar. It doesn't look much like a F86 apart from the general configuration. Its an artist's impression anyway, not the real thing. The tail definitely looks Italian though.

[delcyros]

It is going to be even more suspect with this drawing. The canopy don´t fit to the artists picture (who actually took a F-86/F-84 canopy and not the italian one). This underlines that he was very much influenced by the F-86. I see more problems in this design: With the jet engine moved into the center of the fuselage there is no space for the fuel tanks left. Calculate the average fuel consumtion of a Jumo 004 B (around 1,44 Kg/(100 %thrust)sec.) and the given range you would need between 1000 kg and 1350 kg fuel (depends on altitude and drag). Where should it been placed in this design? In the wings? Impossible, such a small wing cannot bear the complete fuel, even if it bears only one third of that fuel the wing would become very thick (increasing drag and reducing critical Mach speed).

and incresing drag further, that's a very good point del...........

[delcyros]

That´s it, Lanc. With increasing drag you loose speed (and range). I believe that the Re-2007 would need a new fuselage design (since the Jumo-004 doesn´t fit) or beeing replaced by BMW-003 A2 (with less weight and less sustainable thrust) powerplants. Both would need considerable time (and thus also delaying the development of the Re-2007, so a timeframe between mid 45/late 45 and early 46 for ti´s deployment would be possible).
The given range is overrated a lot, the Re-2007 would more probably have a comparable range with the He-162 than anything else (at best).
The speed is also overrated. The drag produced by the canopy and (thick?) wings would be quite large, even with slightly swept back wings. I really don´t see why it should have a comparable speed to the soviet MiG-15 / La-150 (which also are small and light weighted planes) while it lacks so much thrust?! A speed between 520 and 570 mp/h is more probable than a speed between 600 and 650 mp/h.

yeah i mean that's a huge speed for a plane like that........

You read me like a book

[the lancaster kicks ass]

i know you too well.........

[red admiral]

The Speed figure might not be as far off as you think. If you look at the other Italian fighters, G.55 et al, they were doing 400+mph on only 1500hp. There were other designs, e.g. the SAI 207/403 that could do 400mph on only 750hp. This would leave me to believe that the Italians have very clean airframes.

[the lancaster kicks ass]

yes but think how much heavier this jet would be...........

[cheddar cheese]

Weight shouldnt really have much to do with top speed. Just look at the P-47, for example.

[the lancaster kicks ass]

yes but the P-47 also had a hugely powerfull engine...........

and as a car man you should know that weight has allot to do with speed...........

[cheddar cheese]

No, as a car man I know that weight kills acceleration and handling. Top Speed is largely unaffected.

[the lancaster kicks ass]

ok well take into account pewer to weight ratios..........
