DCS: P-47D-30 Discussion

[NineLine]

No worries, any help is appreciated.

[Sporg]

We have enough schemes. We need tunnel and flight tests data both.

If you have anything I'll be happy to hear that.

I found some stuff of different kinds:

 

P-47D-30 lateral and directional stability and control characteristics analysis, with some flight versus wind tunnel data comparisons:

August 1943 vibration and flutter studies on P-47 tail:

3 different YP-47M four-blade propeller performance analysis:

http://digital.library.unt.edu/ark:/67531/metadc63780/m2/1/high_res_d/20030063262.pdf

 

A page describing the P-47 airfoil:

And finally a general NACA 868 report on lateral control.

This one has helix angles and roll rates for different fighters, including P-47, with 50 pounds stick force @10000 feet altitude, on pages 165 (fig 46) and 166 (fig 47):

Could any of this be useful?

[NineLine]

Yup, we have all those as well :)

 

They are looking for full reports on wind tunnel tests, these are more studies on certain aspects, although in many cases can be helpful.

Yo-Yo is very familiar with this resource.

I supposed....

 

Will there be anyone more than he has done wind tunnel tests in addition to the NACA?

 

Another option is to ask NASA to make a more complete simulation model fluid ... though it might cost too much money (it's a joke) :megalol::megalol::megalol:

[Barrett_g]

The inability to find important documentation on key contributors of such a historical event is EXACTLY why this DCS project is so important.

 

This stuff needs to be recorded.... for historical reasons.

 

It won't be long before accidents happen, just like Jackie's Revenge encountered this passed summer, and there won't be any flying examples left.

 

More importantly than the aircraft, are the last of the WWII

Veterans that we lose each day.

[Andy1966]

I agree 100%.

[SlipBall]

It is a common business practice and sometimes government requirement to make copies of such important test results to forward along to those who would consider procurement of these government war aircraft....that's why I think it possible to find in some storage or library these very interesting documents. There are people who do this as a living, and search for you, for a fee of course :P

[Barrett_g]

Wasn't Brazil the last to use P-47's? Maybe they have some copies as suggested above?

I'm not sure, Brazil had the P-47D till like 1954.

 

I have some friends who may can provide me some info/data about the P-47D, if I get anything, I'll post it here.:)

[Andy1966]

found this hope it helps, but they most likely have it already

[Andy1966]

very interesting

[probad]

it's fairly safe to assume any info you can find while sitting in your chair has already been found by ed. we hardly have a monopoly on using google.

This.

 

Unless people are prepared to do what renhanxue has been doing for the Viggen by contacting museums and archives along with firing off FoI requests to various government departments, then you're not going to get far.

[RAZBAM_ELMO]

Have ED not contacted planes of fame for flight yest data from their p47. How many are actually flying?

Yugoslavia received 133 P-47D-40RA which were used from 1952 until 1961.

 

Peru used P-47s until 1963.

Quick update:

 

A friend of mine is going to a museum to see if he can get some data about the P-47, if he gets anything, I'll post it here.

 

Also, there's a book called "Senta Pua"(which was made by former P-47 pilots), and there you can find several reports about the P-47 flight model, but the problem is, the book is all in portuguese, I would have to translate it.

 

"Senta Pua" is about the Brazilians P-47D fighting over Italy in the WWII.

The Fighter Collection has the razorback version.

So then for the most part if they offer fuel for a day there's 95% of the flight test data done right?

That might actually be a solid solution.

[RAZBAM_ELMO]

I mean granted you won't have the same data over the canopy and behind the canopy on the top of the fuselage between a bubble and a razorback.....but everything else is exactly the same.

They had, I saw her flying at Duxford 2012(?) I think, but she was sold to a USA customer afterwards. Anyhow, provided TFC had the required information for a DCS module, and bearing in mind they are DCS partners, wouldn't they already gave that information to ED? So I guess they don't have such information.

You don't gather wind tunnel data from a flight. Devs life would be much easier that way.

 

 

S!

True but a lot of info was gained from flight data recordings from the mig21 from LNS. Data can also be gained from pilots certified in the bolt similarly to how they accomplished the fm for l39 and f15.
