Pussy.
I did 102 in a Prius. Also did 94mph in an ambulance with 400k on it. Legit though, I’d probably shit my pants at Mach 2 |

Quoted: https://www.19fortyfive.com/2022/05/what-it-felt-like-i-took-the-f-16-fighter-to-nearly-mach-2-0/ I was at 25,000 feet when I pushed the throttle forward, rotated it past the detent, and engaged full afterburner— As I maintained my altitude, the jet started to accelerate. At 1.4 Mach, with only about 2 minutes of fuel left, I bunted over and started a dive to help with the acceleration. In my heads-up-display, 1.5 Mach ticked by, backed up by an old Mach indicator slowly spinning in my instrument console. At 1.6 Mach, the jet started to shake. I was expecting it—the F-16 has a flight region around that airspeed that causes the wings to flutter. Still, this jet had a lot of hours on the airframe, and if anything were to fail, the breakup would be catastrophic. Similarly, ejecting at that speed would be well outside the design envelop—the air resistance at Mach 1.6 is about 300 times what a car experiences at highway speeds. A few pilots have tried, only to break nearly every bone in their body. So now, the option was to slow down until the vibration stopped, or push through until it smoothed out on the other side. I was running low on fuel, so I elected to increase my dive so I could accelerate faster. Slowly 1.7 Mach ticked by, next 1.8, and then at 1.9, everything smoothed out. I was now traveling 1,500 mph over the Yellow Sea. The cockpit started feeling warm so I took my hand off the throttle and put it about a foot away from the canopy and could feel the heat radiating through my glove, similar to sticking your hand in an oven. |

F'in commies have been building jet engines for 75 g-d years and can't figure out how to use stolen tech well enough to make an engine that doesn't need rebuilding 3-4x sooner than a similar Western engine. I doubt they're 3-4x cheaper to build, too. |

Quote HistoryQuoted: And you were comfortable because Concorde uses a fuel-cooled intercooler between the compressor and turbine of the air cycle machine. I don't think any model of F-16 has an ECS configured like that, and that's most likely why this pilot was feeling what he was feeling.

My brother is retired from the Navy and last year when we were out on his sail boat, he said pretty much every performance number on a ship or aircraft is complete BS. Still wouldn't tell me the goods on a few ships and jets I asked about. Did tell me that if he told me what a carrier could do in calm seas vs what is reported, I wouldn't believe him. |

No idea if it's actually true, but wouldn't surprise me too much As far as I know it is decently over 40. IIRC they are publicly known to run 36 knts or so. I said 40 in conversation and he smiled and said no. Which I assume meant faster. Still insanely impressive for the draft, drag, sheer size and weight, prop thrust, ect. |

It’s a well-known concept and I’ve read about other planes having windows heat up too hot to touch at speed. What would anything happen to do with an engine cause the canopy to heat up? The principal cause of heating on a fast-moving body through atmosphere is not friction (drag) but compression of the air. Bolus of compressed, superheated air is radiating onto the aircraft much more strongly than slipstream cooling from the boundary layer can carry heat away. |

Quote HistoryQuoted: Quoted: Quoted: Quoted: Quoted: 2.04 in Concorde Umm no dude, thats called friction at that speed heating up canopy Dude I have no idea what you’re talking about but it’s airframe heating and friction on canopy that limits some aircraft. It’s a well-known concept and I’ve read about other planes having windows heat up too hot to touch at speed. What would anything happen to do with an engine cause the canopy to heat up? 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. |

I've heard that some models of Mig-23 have very stringent speed limits set because of the risk of a canopy failure.
If an F-16 canopy failed under pressure would it shatter? Or would it crumple in? Has such a thing ever happened? |

IIRC in the old days of the cold war, I got the feeling that we were pretty honest about our capability, with that whole defense spending dick measuring competition we were held bent on winning by a country mile The ruskies would then come out with their newest thingamajig and juust maybe they would exaggerate or embellish a wee tad little bit. It looks like our style later became, understated AF. "Oh man guys we are retiring the Phoenix missile but we toooooootally don't have a 1:1 replacement, oh we promise, tee hee  "
