What aerodynamic data (drag/lift curves) exists for the A-10? This is one of 3 question in "series" - one question split up in 3 to better reward those responding about each aircraft. Other questions: Yak-131, L-159

A-10 is one 3 planes that are used in the ArmA 3 combat simulator, but its aerodynamics modelling currently lacks significantly. I'm planning on writing a short "essay" to developers regarding what and how can be specifically fixed in the flight model, but I'd like to back my research with some hard data. Specifically, I'm interested in any of the following:


L/AoA
D/AoA
Side lift/SA (Slide angle)
Max G/velocity
Flight envelopes (like one below for F-15):




Torques can well be left out - it's not a full fledged simulator, but the above data can give quite a good estimation of high level characteristics already.

Are there any good sources on any of the above data? I've found some (see below), but the quality leaves a lot to desire. Low-mach data is good enough for me.

I understand this is a tall order, but, well, SE is for expert answers - maybe a wonder happens and someone here has it? :)

What I've found so far:


Some superficial modelling of A-10
A-10 airfoil: NACA 6716 root, NACA 6713 tip
Set of A-10 documentation
Good luck finding number 1-3 on your list.  As far as I know these are proprietary data the you would have to get from Fairchild Republic.  After a career of flying fighters I never saw this data or really care about it.

In my opinions numbers 4 and 5 on your list are much more relevant.  What you are looking for are called EM diagrams.  EM stands for energy maneuverability and these diagrams show a scale of turn rate, turn radius, airspeed and altitude to display meanueverability at a given energy state.

Using these diagrams you can find some key performance factors:

Min maneuvering airspeed - where the rate and radius slope drops off on the left of the chard showing min flying airspeed at given altitudes and wing loading

Max instantaneous rate of turn - max possible turn rate given a certain energy state - top of the rate curve then drops off

Max sustained rate of turn - maximum rate that can be achieved while maintaining your energy state (Ps = 0)

Corner velocity - velocity to achieve max rate at a given energy state

Min radius - smallest radius of turn acheveable given a certain energy state

Radius for given conditions - important to determine this when planning something like a targeting attack

I've found an A-10 EM diagram and a good Mig-21 diagram that annotates the factors I have defined above.

Note:  I have to giggle at your "Low-Mach data is good enough for me" statement.  There is no high-Mach data in an A-10.  It will top out around .6 Mach (max speed around .7)
