The R-77 'ADDER' - History, Design, Performance & Discussion

Stuff happened…

Damn, did I miss something again? Was it the R-73E brochure or the Su-30 man.?

Idk

What and where did he post

It does not matter, let us focus on the R-77 so no one shares such a fate.

So will you share the bbcrf sims?

Also, as i said before, would be better if we have amrram simualtion as comparision

There already exists AMRAAM aerodynamic simulation from DCS, but BBCRF’s sims were already posted right above…?.. and I just said I would share what he sends us…? So what are you asking?

That wont work well, as different simulations could give different values, not to mention quality of 3d model may also differ. Doing it under same simulation gives us accurate conparisions, even the the face value might be wrong, this could be used to compare in game values between amraam and r77 in term of ratios.

Oh damn, it would be more helpfull if we get drag coefficient / drag VS mach number graph

something i’m noticing is it’s simply the lattice itself and not the whole missile, and again, different sime, different results, can’t hurt to have different sims

because it takes alot of time to calculate complex areodynamic shapes in a simulation

yeah

Hmm, less drag at grid fins at higher speed

yes,

the r77 only has really bad drag at transonic speeds

around 0.8 to 1.2 mach

we know they aint putting this in the game unfortunately

Keep in mind Mach 5 is a ridiculous number and the missile will rarely be above that, it will mostly be within Mach 1-3 in most situations

the r77 only has problems with drag at transonic speeds

around 0.8 to 1.2 mach

it is fine at any other speed

the mach 5 is just an overexaggeration

Both use ANSYS to run the simulation

The exact specifications of both missiles are modeled, the only thing that may differ is number of vertices in the models, regardless, both are done to the same standard with quite a lot of vertices.
