yes with RAM and ferrumpaint, so what???

again sferin,

but in general terms isnt about if the chined nose increase directional stability, is about if conical nose increase directional unstability

and again

man i explain you with chined nose you avoid lateral component of the sw, is the same problem with the 2 seat BB, you create other lateral forces, you must understand that a side force in the nose has big momentum, because the nose in looooong

also we arent talking about the speed problems, only the directional problems, now these last also induce more drag bu that is other topic

yes but again is the “we waste tons of dollars in a good proyect”, it was good, but is also overhipped, again that also depends of the contratists behind an the money involved, yes it was a mistake from me to put the sr71 in the discussion, i didnt read all the document ,for me is irrelevant, now that i read it say nothing abot the sr71, but who cares????

about the designers, i just explained that there are tooo much contradictions

public or not are from politic nature, not technic, you know, “hey mr. president or congress please bring me more money to my proyect”, im not an intelligenge expert , but the CIA is also a politic institution, i think that you have seen too much james bond movies

So because it was an internal CIA document, it is automatically 100% false. Care to share the logic behind that?

a public document about that topic , is obvious that isnt 100% false, but these documents falls in the congress, so they are somewhat biased, and not reliable, and just not technical, you must understand what is the difference between a tech doc and a politic doc, this last are just the same as the fans-books

those arent technical documents are politic documents

Why you don’t believe the guys who built the damn thing is still beyond me…

because there are things that dont match, you are saying that they were worried by the chined nose, but actually they were much more worried by the conical nose, because they are saying that the plane with cilindrical shape and cones are bad for stealth, but then what is the sr71???, because they are saying one reduction of 90% rcs only by the nose, thats incredible, because you see only details in the plane , but not the whole design , etc……, and because i have at least some mother nature laws knowledge, the things just dont match

I wonder why the TA-12 two-seater didn’t use ventral fins? It had the same stepped-cockpit arrangement.

well, we just dont know, but also we dont know the true performance and behavior of such configuration

I’m sure some people would ( at least I do, in part).

Now I’m familiar with Reynolds number, but what do you mean by “entropic relation on fluid dynamics” ??? Entropy is not to be used lightly…

entropy concepts are widely used in aerodynamics, determining the energy relation in the gases, the gas behavior, etc.. under expansion or compression, look im not here to be the “wised” and “smarter” guy, only to try to start a more scientific debate, nothing more

i know that again im discussing with guys with 20 sr71 pop-books, or 40 posters or 200 pics of the blackbird, so what can i do???

again you guys can believe whatever, but the facts are there

my best regards, goodbye
