Weta43 Posted February 4, 2006 Posted February 4, 2006 The Su 25 doesn't get the "sound Barrier" effect (Quiet cockpit, silence then boom as it passes) no matter how fast you go - which is a shame 'cause clean you can just squeek over Mach 1 in level flight & it's fairly easy in a shallow dive (appart from the changes to handling). Cheers.

Maybe its part of the AFM...since that doesn't actually happen in the cockpit IRL. ;)
Weta43 Posted February 4, 2006 Author Posted February 4, 2006 I thought I'd read that there is a quietening of the cockpit once you pass Mach 1? It would make sense - engine sound from outside doesn't catch you, only that transmitted through the plane, & there should defianately be the effect outside, if your faster than the sound you're making, you'll be quiet from the front till you go past (with an overpressure wave & then the sound of your engines) I think it's probably just not there for the same reason there's no heat blur for it or the A10, Dev's just thought it didn't need it ,BUT IT DOES! Cheers.
Guest IguanaKing Posted February 4, 2006 Posted February 4, 2006 Ahhh...OK, there were two parts to your observation, I guess I missed that. :D According to the Viper and Eagle drivers I have talked to face-to-face, there is not much change, if any, in the in-cockpit sound when passing Mach. Wind noise is always going to be there and actually gets louder. But...they DID say that small changes in sound levels would go mostly unnoticed since they always wear ear plugs in their ears and turn the audio up in the helmet to compensate for the ear plugs. ;) Outside...well...there should be an instantaneous arrival of sound, but there is still nothing in the game, on any aircraft, that sounds anything like a sonic boom. :D When you fly the T past Mach...is pitch still controllable? If it is, I believe you have exposed a flaw in the flight model. Heat blur on the A-10, I think would depend on OAT. Only about 30% of the TF34s thrust comes from the turbine, the rest is from the fan. There probably should still be a small one at the turbine's exhaust though.
Weta43 Posted February 4, 2006 Author Posted February 4, 2006 Don't remember, like I said in another post it's realy the vanilla I've been playing with lately. In that then barely at just over & progressively worse. As you approach Mach 1 the plane starts to shudder then wants to slowly dive, & at M0.9 - M1.0 you'll be flying along with the stick hard back to stay level but you don't realy have a lot of control in that if if you center the stick you won't suddenly snaap into a dive. The plane just wants to turn down & with full stick you can just about overcome it. If you dive from high & get up a good speed you'll have the stick back & no chance of pulling out of the dive, you have to put on the brakes to get the speed down to regain control. Try it & see. Cheers.
Guest IguanaKing Posted February 4, 2006 Posted February 4, 2006 Wow!!! That actually sounds fairly realistic. :icon_supe Usually, the area surrounding the elevators becomes a low pressure area, and the elevator authority is severely diminished...if not completely negated. The behavior you describe sounds accurate. Releasing the stick won't snap you into a dive because your elevator is essentially, helplessly flailing around in a near-vacuum. ;)
