Mach limits for fuel tank, and ground weapons.

[CrazyGman]

So based on the manual, when flying the mig-29 with a fuel tank your speed is supposed to remain under 0.9 mach, and 0.8 mach for external rocket pods and bombs.

However just because these limits were set in the manuals doesn't mean that they weren't exceeded in the field. For example the Mi-8's weren't suppose to bank more then 30 degrees, but pilots often did in actually combat. Also the Mi-24s were only supposed to run their engines at higher rpm settings for only limited times, but im reality they ran them as needed, and what you got was engines that just wore out faster and produced less power over time, but didn't catastrophic fail.

Does anyone know how hard the mach limit for the fuel tank and stores had to be followed? Was it there just to preserve the overall life of the fittings? Or was there significant risk of something failing when going a bit over?

Again you have instances where planes like the F-14 had g limits of 7.5 but pilots would go above that limit not infrequently, and there wouldn't be catastrophic failures.

I have also seen Mach 1.5 limits for the centerline tank. Which is about where you jettison it in my profile/recommended manual profile as well. 
 

I have never seen g limits for ground weapons, only speed limits. For example it seems no faster then Mach 0.8-0.9, I’m a bit too lazy to look up exact limits right now.  
 

One issue with S-8 is detonation of the rocket motors from aerodynamic heating.

True that

[AeriaGloria]

Okay have a list of limits here 

Bombs - Mach 0.8 

KMGU - 900 kmh, 30-500m level release altitude

Rockets - Mach 0.8, flight time above 900 kmh is limited by wether pod has heat protection or not

 interestingly, it also says that KMGU does not require the brake/retarded switch forward.

In one of my docs I can see:

1. for bombs -100 and -250 or -500 (up to 4pcs) - G limits +5/-1.5

2. for 2 KMGUs - G limits +5/-1

3. for 6 -500 bombs - G limits +4/-1.5

Makes sense!
