The project would entail the creation of EXACT exterior reproductions of famous WWII fighter aircraft for airshow, static display and TV/film production. Said aircraft are required to be aerobatic capable. Provisionally: all originally water cooled engine aircraft will incorporate the Allison...
Berkshire raises an important point: the exterior dimensions, curves, outline, and shape of the aircraft is set and predetermined, (with the limited possible exception of the airfoil selection.) There can be no compromise on the exterior exactness of the reproduction, a "close, but not exact...
I forgot to mention that the tooling (entire construction process) would (hopefully) be subject to continued production beyond the first five. The idea would be to sell follow up examples in kit form.
I posted the following question on the Aerodynamic forum:
"Would it be possible to construct exact reproduction WWII aircraft out of composite materials? The structural weights would be much less, and the weight distribution would be dramatically different, and that would impact CG and wing...
Yep. Thunder Mustang is .75 scale (with the exception of the wing span which is .65). It's an amazing example of what can be done with carbon fiber and epoxy.

Thank you KENAT and berkshire for your responses. Mustangs and Spitfires are still fairly numerous, though the lack of Merlin engine parts is becoming a serious problem. Thunderbolts and Lightnings, and Wildcats, Hellcats and Corsairs are fairly scarce. Fying examples of German and Japanese...
Would it be possible to construct exact reproduction WWII aircraft out of composite materials? The structural weights would be much less, and the weight distribution would be dramatically different, and that would impact CG and wing placement, but could all that be worked out?

What is the 90° orientation actually doing in a wing? Not for tension or compression in span wise bending loads. Not for torsion. The other orientations seem pretty straight forward, but I can't visualize the purpose of the 90°.
Thank you!

Compositepro: How could you read that post as a diss? I merely pointed out that everyone knows what "integral" means, and I asked two pertinent questions.
Oh, I get it. You meant that SWComposites was patronizing me--and I pointed that out, and I wasn't supposed to do that? Is that what you...
SWComposites wrote, "Integral means the stringers are cured/bonded with the skin. They are multidirectional lay ups as are the skin laminates."
Yeah. I think we all know what the word, "integral" means. You have direct knowledge that the stingers are laid up multidirectionally? Because a...
Aviation Week had an interesting article a couple months back about the cancellation of the mostly composite Bombardier Learjet 85: http://aviationweek.com/business-aviation/bombardier-learjet-85
From the article:
“For the Learjet program, Belfast fabricated the upper and lower wing panels...
A hypothetical wing has a -/+ 5-degree trapezoidal hi-aspect cord and the main spar has a similar 5-degree taper past the landing gear attachment point. The rear spar is full length and tapered forward 5-degrees. Unidirectional carbon fiber is selected, as is a +45/-45/+45/-45 orientation. But...
Or maybe it does, it's a nozzle isn't it? A well defined airflow goes through it directly into the cute. So, so beautiful--simple, yet wonderfully intricate and complex at the same time.

No, I don't think so. It's responding to the tension in the lines. What happens when the velocity (relative in this case) of a fluid declines?? It's a VERY elegant design isn't it?

Notice the function of the ring and how it functions in the lines of the parachute. When the aircraft is at high velocity, the ring closes the parachute to prevent structural (fabric) failure. As the aircraft slows down the ring...
KENAT wrote, "Flaps deployed for take off but not during maneuvers where stall occurred?" Almost has to be, and that brings me back around to the split flap question. If take-off with a fully deployed flap is 130mph, and a stall with a clean wing is 155 mph, that paltry 25 mph difference is a...
My apologies. It just dawned on me the engineers on the list probably do not have access to the flight characteristics of the Ta-152H.
According to Willi Reschke who flew the Ta-152H-0 in combat beginning in February of 1945: "The aircraft (fully armed, fully fueled, at all up weight) lifted...
I am under the impression that split flaps provide very limited amounts of lift, and aerodynamically, they act as spoilers and air brakes more than flaps. Also, historically, split flaps were a very short-lived fad among late 1930's aircraft designers, and they quickly faded out of use. So back...
The wingspan of the Ta-152H was 14.44 m (47' 4.5") and split flaps were 8.4 m of that: 4.2 m (13' 9.5") per side. Focke Wulf utilized split flaps on the Fw-190A-G and split flaps were utilized on the Supermarine Spitfire. What were the design/engineering consideration(s)/imperative(s) of...
FastMouse wrote, "Recommend keeping the concept of AoA and angle of incidence separate." Roger. I see the importance of that.
I have a question pertaining to the split-flaps on the Ta-152H. On most forums, a change of topic would mandate a new thread. Is that the protocol here?
Thank you...
