ChoSeungWan Posted November 30, 2014 Posted November 30, 2014 Do they rent/buy the actual aircraft and put it through a wind tunnel? What is the process of getting permission to model systems from governments? For example, how did ED go about acquiring information on the A10C? Has ED or any third parties had their requests for aircraft information rejected by governments under operations security?
WildBillKelsoe Posted November 30, 2014 Posted November 30, 2014 I think wind tunnel tests but on scaled models with actuators and control surfaces, data derived and then real pilots (if available) are consulted to fine tune the models. This is from the back of my head so dont take my word for it, except if they own the aircrafts (eagle dynamics and fighter collection) like what happened with the P-51D. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.
Art-J Posted November 30, 2014 Posted November 30, 2014 I don't think folks who really know about acquiring permissions will answer these questions, because: a) they might be tied by NDA; b) they might not be interested in revealing their detailed business practices to customers, who by default don't need to know these. In case of A-10C the job was "simple", because our sim is a side-effect of a professional sim ED guys were asked to make for Air National Guard. Therefore, they didn't have to hunt for data, because they got it from their client in the first place. Would they be able to make such a detailed sim if they were just some obscure programming company without government contract? I doubt that! As far as third parties are concerned, You might search for posts of Pman in VEAO section of the forum, because it seems they indeed "had their requests for aircraft information rejected by governments under operations security" or had other licensing/financial obstacles from aircraft producers getting in their way. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.
aaron886 Posted November 30, 2014 Posted November 30, 2014 It's nothing secret. Go look at the flight model standards first, but I think you've already done that. The actual creation of the flight model does not follow any specific method, but to reach PFM standards the author is going to need highly accurate data and performance figures to verify it. It can be done a few different ways, but the measure of performance/handling quality is the results rather than the method.
