Trying to hit that Mach 2.5!

[mytai01]

The actual aircraft was at 40k for it's max mach speed run. But, you must understand that the maximum capabilities of the aircraft are not the practical capabilities of the aircraft. These capabilities were demonstrated more for show (to the Soviets) and experimentation than anything else.

After 800kts indicated you should be at risk of losing control surfaces... Not yet implemented :-)

 

The real Eagle exceeded 900kts at sea level.

[mytai01]

I also have a book that states that the Eagle's speed is only limited by its wind screen. They said it would melt before the Eagle got to maximum speed.

Mach 1 at high altitude is around 540ktas. That makes Mach 2.5 something around 1350ktas, and at that point your CAS will be between 500 and 600 knots.

 

Well interesting then... how did NASA or even just the airforce get the plane up to 2.5+ Mach? I'm pretty sure that at those speeds even at really high altitudes, IAS is much above 800 knots...

Real eagle pilot advised to model the damage.

Like doctors opinions...get a second opinion...In fact, as many as you can find!!! I'm in the Air Guard, if he's an officer then definitely get more opinions on this!

Which control surfaces will detach from the jet in level flight? Has this ever happened in operation? I think the canopy would unlatch before the ailerons detatched.

 

NASA hit 2.7 with F100's. We should be able to hit Mach 2.2 at 37kft, pitch up and Mach should keep increasing while climbing to 50kft. I can't get that to happen in DCS which is why I had to dive to 34kft

canopy should not unlatch, aerodynamic forces would keep it pressed down.

most likely you would loose the horizontal stabilizers also called elevators first due to them having the least amount of connecting material and the most amount of movement.

[SinusoidDelta]

Just a wild guess about the canopy, probably unlikely.

 

It seems like the 800 knot limit was in response to a fatal compatibility flight profile test [ame=http://usaf.aib.law.af.mil/ExecSum2002/F-15C_GulfofMexico_30Apr02.pdf]Accident Investgation Report here[/ame]

 

The left vertical stabilizer delaminated and a large section of the front leading edge broke off at 780kts@ 24,000 ft. The pilot initiated ejection but had no chance of surviving...

 

Some more applicable information I've found:

Very interesting read and some good information!

[ShuRugal]

The right boom, right tail, and right horizontal stabilizer departed the MA, followed by the right (#2) engine. The forward fuselage and cockpit area separated from the remainder of the MA, which liberated fuel from the #1 fuel cell and caused a fire.

 

I think the words to describe this are "holy ****ing shit."

yeah must have been pretty devastating for all of that to happen to your aircraft within seconds, also knowing ejecting would probably be very futile since you are at very high speeds. RIP MP.
