Hey, Everyone
Is there any chance to get weight and Balance data for the Mustang? Thought of someting like an old Tech Order or similar.
I am trying to get a feel of where the CGactually might be at a given loading, especially with fuel in the FUS TANK.
Thanks in advance for any reply!
Cheers
Marco!

Hey, Tug!
Thanks for the hint. That site has the P-51D Training Manual, wich I already have. (And a neat blue print to hang on the wall...[FACE WITH STUCK-OUT TONGUE AND WINKING EYE])
TO No. 1F-51D-1 refers to TO 1-1B-40 for W&B data. I am sure the latter contains some figures of the stations arms and the CG envelope.
Could not find it anywhere! Even in on line aviation shops, or so.
Oh, another idea....does the developers crew maybe have any information they are allowed and willing to share?
Thank you all!
Grüße!

Re: Looking for P-51D Weigth and Balance Data
I think it may be hard to find. Mass properties for tactical aircraft is rarely done that way. You have set approved configurations, with our without limitations, and that's typically it. For those, other issues such as safe separation are also considered. You simply don't fly other configs than those ordered from and delivered by the OEM, hence no need to know the actual CoM or CoM limits.
Be warned: Aero engineer, real life pilot, sim programmer. Nothing good can come out of that.

Re: Looking for P-51D Weigth and Balance Data
I picked up a PDF copy of the 'North American P-51B,C,D & K 1944 Basic Weight Checklist & Loading Data' (T.O NO. 01-60J-5) from one of the online manual sites, but can't remember which one!
However, you'll find it as a download from esso Aircraft Manuals : -
https://www.esscoaircraft.com/p-9661-no ... -data.aspx
It should have all the info you need!
I think my copy had some pages missing (when I compare it to that of the W&B T.O for the P-40N that is), but it was still very useful.
(CoG limits for the P-51D/K were 21% to 31.5% MAC btw)

Ft,
I agree with you, partially, knowing that it might be next to impossible to load a Mustang completely wrong...with all these hardpoints to hang your stuff on.
But it is still interesting for me, where the CG might be, with fuel burn and various load outs, etc.
The Position of the CG does have an impact on flight characteristics in every phase of a flight, especially in aerobatics or when you are trying to come back to terra firma.
And as an engineer I really need some figures to chew on.
@Bradburger,
I suppose the Manual with that cute red li´l aircraft is the one you are talking about. Noes not look like military handbook to me. Kidding! Tanks a lot! I´ll see if it holds the needed info.
Ah...and..what does that %WAC exactly mean? As a german PPL I have never heard of this value.
Grüße!

MAC = Mean Aerodynamic Chord (a term which you are might be familiar with).Anawake wrote:

See http://en.wikipedia.org/wiki/Chord_%28aeronautics%29 & http://en.wikipedia.org/wiki/Center_of_ ... n_aircraft
So if we take the P-51D/K, the forward and aft CoG limits are 135.8 inches, and 144.2 inches of the datum point respectively (the datum point being 119.1 inches fwd of the Mean Aerodynamic Chord (which on the P-51D/K is 79.6 inches) so that's 21% to 31.5% MAC.
I think when you get the weight and loading T.O. and see the CoG diagram, things will be clearer!
Hope this helps
Cheers
Paul

Well, despite thinking this, this exact problem occurred with the Spitfire, around the time that the MKV was in operational use.Anawake wrote:Ft,

There had been a number of structural failures with loss of both pilot and aircraft (especially when pulling out of dives), whilst some squadrons were reporting problems with aft stability, whilst others weren't (also the structural failures).
Basically, the upshot was that as more equipment was being introduced to the aircraft and the CoG went further aft, it would seem that on some squadrons, the ground crews were not adhering to the weight and loading data chart in the Air Publication (maintenance & service manual), and were exceeding the aft CoG limits!
Hence the introduction of bob weights to the elevator circuit as a temporary measure (something also done on the P-51 as the CoG went aft, and stick force reversal occurred), and later on, the extended horn balanced elevator as permanent solution of extending the aft CoG limits of the Spitfire.
