Quote History Originally Posted By agriebel: 2 min of fuel left? Yeah this was the part of the story that didn't ring true for me. No fighter pilot is intentionally going to get to such a low fuel state AND keep the aircraft in afterburner. That's total theatrical BS but if true the guy should have his wings ripped off. I got to Mach 2 in an RF-4C (slick configuration) over the Pacific in 1987. I actually did it several times. The first time we climbed the jet up to 53000 feet (max for the F-4 was supposed to be 55K and we were wallowing around and couldn't push the altitude any further) and we were in full afterburner for 15 minutes before we pushed the nose over. The jet was at around 1.6 Mach when we started the dive and we pushed over to 45º nose low. We went through Mach 2 at around 29000 feet but the aircraft was shuddering petty badly and we experienced a violent jolt at one point (turned out we had ripped a piece of the underbelly paneling off the jet - my Squadron CO was not pleased). We decided to rethink our strategy because pointing the aircraft at the ground didn't seem to be the best way to do things. We rememebered that in F-4 flight training that an aircraft will max accelerate under unloaded/Zero-G conditions. Our next attempt we got to 53K altitude and when we were at 1.6M and the aircraft would not accelerate any more we gently pushed the nose over until we were at Zero-G and we were light in the seat. This resulted in max acceleration in a gentle arc instead of a suicide run for the ground! The jet broke Mach 2 aound 40K feet (no shuddering this time) and top speed on that flight according to the Mach meter was 2.2M. After that just about all the guys in my squadron made their own successful attempts at breaking Mach 2. We even had special patches made up to commemorate the feat that we wore for a while until the commander told us to stop wearing them. Good times. The F-4 was a beast! |

The canopy sees this stagnation temperature only on a very limited region at the front of the canopy. The majority of the canopy, say 80%, sees roughly 7/10ths of this aerodynamic heating. And then, you have to factor in the thermal conduction and thermal capacitance of the polycarbonate canopy, the latter being rather significant. The most common issue with a high flying aircraft is that the canopy is cold soaked at altitude in subsonic flight, and when descending into air with higher moisture content at lower altitudes, the inside of the canopy can fog or ice up because of thermal lag and insufficient canopy heating on the inside, and outside for that matter. To overcome this thermal lag/capacitance, some aircraft will have heating elements embedded in the interior of the windscreen laminate. The 16 has no heating elements. It is all done via the ECS and there are vents on the glare shield along with the manually set defog lever on the side wall it directs airflow along the inside of the canopy. |

Skipper (Ernest Tissot, odd I remember that) cleared flight decks, cat walks, weather decks, sponsons and kicked that thing in the butt. It was fast. A friend I met later in life was on one of the escorts for that cruise. He told me when Big E went fast they had no hope of keeping up. It may of been BS but he said on radar he's seen Enterprise go almost as fast as it's hull number. |

And, from a descent starting at 50,000 feet, rather than a MAX acceleration starting at and holding 25,000 feet, and it looks like 2.0M was achieved at a more reasonable altitude of roughly 36,000 feet, which is where mission planning would take one for maximum TAS. |

I didn't realize this until today, but the canopy fog/defog is actually modeled in DCS. At least, I think they are talking about a PC sim. Unless this greg12 dude really is a fighter pilot. He's definitely wrong about Willie Nelson, though.

such drama.
I had the Eagle at 1.8 at 55,000 feet there was no drama, it just went fast like it is supposed to do, no shaking, no noises, just going fast. PSA. Bailing out at 600 knots or mach 2 isn't going to make much of a difference, your pretty much dead no matter what, same if you hit the ground, or the thing comes apart. It's a risky game, either enjoy it or get the fuck out. |
