So, where would they get the real-life aerodynamic data from?

 

They would probably make it up like pretty much every Developer out there.

The smoothness of animation, that add to real-world flight viability..is DEADLY!

 

That alone, in my opinion, would be enough to purchase the sim at the Student license level.

 

There is much more...believe me, that eclipses FSX (even at DX10), but you truly have to 'drop the dime' and see what is...and how the 'what is', is running on your own system, to be the judge. I would dare say from my most meager usage to date...that there are going to be not too many user-requests,  for a refund.  I for one will not be...(large smile).

Didn't you write in another thread that you intended to wait until P3D become a 64 bit application before buying it? At any rate I did dropped the dime yesterday and bought P3D. I have just installed it and started it once. Now I have a lot of work in learning it and installing all add on products that I can

use with P3D.

Then what's the point?

That's exactly what my wife asks when she watches me flying around in a pretend aircraft on my PC

Then what's the point in developing better flight dynamics if developers simply make it up = GIGO?

Gerry, there are plethora published reports on specific aircraft's performance envelope during all phases of flight. One does have to invest both the time for research, and sometimes dollars to obtain them though.

Does that data provide for example realistic aerodynamic coefficients etc needed by Prepar3D ?

So, where would they get the real-life aerodynamic data from?

 

All kinds of ways to obtain data and they will vary based on aircraft and cost.  Strain gauges to measuring forces on a wing/surface, rows and rows of pitot tubes, wind tunnels, anemometers.

 

Some aircraft are designed on a computer using high end (read $20,000+ per license) flow modules that are add-in's for solid modeling software (i.e. Solidworks) ... they can simulate flow (rendered, not in real time) to get one pretty close to actual measured results.

 

But like Bill suggests, no point in spending millions of dollars on this type of data if the aircraft being designed is being sold for $90K and flies well enough with or without computer aided design.  As with all things mechanical, the more accurate the more it costs.  For example ring gap tolerances in a piston engine ... typical street car maybe 0.0027-0.0056 of an inch ... in a formula one race car it would be 0.0002 - 0.0009 ... doesn't seem like much of a difference, but cost wise to produce that level of accuracy is exponentially higher.

 

My data acquisition system on my race car operates at 100 Hz (so 100 samples per second) ... for most of what I need that is enough.  But when I want to log data of shock motion (single sensors that attach to top/bottom of a shock), 100 Hz doesn't cut it, I need 1000 Hz sample rate to understand what my shock is doing and where it's not working well and then come up with correct valving.  And of course, logging data at 1000Hz is much more accurate and of course more expensive (equipment wise).

 

I don't know if that answers your question.  But when I see one product claim more advanced "flight dynamics" than another it does make me chuckle a little ... especially when an end user that has never flown that specific aircraft makes the comments.  A flight simulator can only go so far, and that's fine, still a great learning tool in many ways even if it's not 100% accurate and never will be ... and that's ok, it doesn't need to be.  Next stop is feeling it real world ... and it's definitely different but by no means invalidates any part of the simulated process or using it as a tool.

 

Cheers, Rob.

I think you both have missed the point. I responded to this post
 

Flight dynamics can be changed by third party as kind of a plugin with P3D2.  I think its only a matter of time before someone digs into that toybox.  Isn't that why/how Laminar Research got started?  Maybe they can make a plugin.

Obviously aircraft manufacturers will have this available but  3PD flight simulator developers are not going to have access to this data if only because the manufacturers will not provide it generally.

I would guess that the Lockheed Martin Devs just might be able to find some aerodynamic data from somewhere Gerry.

It's not as if they don't actually build the things from time to time.

You think Lockheed Martin will give the F35  aerodynamic data to any anyone who asks for it?

Probably not, but that's just one aircraft of a highly sensitive nature.  But honestly, even if they gave that data to someone ... are you suggesting that "someone" could build an F35 from that data alone or somehow influence that "someones" military direction?  But seriously, you could probably hand over F35 blueprints of every system to North Korea and 60-70 years later you might see a similar aircraft that is 100X less reliable ... the manufacturing process and materials is more the key than the actual aircraft design/specification.

 

 

 

The F-35 took its first flight on 15 December 2006. The United States plans to buy 2,443 aircraft. The F-35 variants are intended to provide the bulk of its manned tactical airpower for the U.S. Air Force, Marine Corpsand Navy over the coming decades. Deliveries of the F-35 for the U.S. military are to be completed in 2037.

 

Now think about that.

 

The good news from this (and you know I like to have a positive spin as much as possible) ... 2037 ... that should keep Prepar3D development going for some time  B)   So for those doomsday folk suggesting P3D could disappear tomorrow ... that seems unlikely.

 

Cheers, Rob.

 

 

Probably not, but that's just one aircraft of a highly sensitive nature.

 

Has Airbus released the aerodynamic coefficients for the A380 to anyone who asks for it?

FAA or NTSB might require the data for commercial ... Possibly for any certified motion simulator. But I honestly don't know.

 

i would think any motion simulator would have it in their lookup tables. And since P3D is the professional sector also

I don't think FAA or NTSB or a certified motion simulator are "anyone who asks for it" especially  a retail 3rd party developer.
