Which is likely because you can't - the numbers are just wrong, and while you can usually argue lots of opinions in life, you can't argue with equations. You don't even try to discuss your numbers, you mystify, claim only you would understand them, claim it's somehow possible or doesn't matter. And calling everyone who points the numbers out names. So there's a number of problems that are spelled out to you.įunny stories, motivational bits, calendar lore. It knows little of the engine performance degradation at such high altitudes. It doesn't know that there's wavedrag at the supersonic transition and you need to do a dipsy to overcome it. The YaSim solver however doesn't provide for the fact that you might want a cruise solution with afterburners on (there's really no other plane that does that kind of thing).
FLIGHTGEAR SR 71 FULL
It also has a supersonic cruise solution at 85.000 ft, but with full afterburners lit. Manifestly that is not remotely what the SR-71 does - it has a subsonic cruise solution at around 25.000 ft (which is where it would refuel). The way the YaSim solver works, it will adjust the FDM thrust and drag values to meet these parameters. On that sheet it instructs the solver to find a solution for a cruise altitude of 35.000 ft with a speed of Mach 3.4 oder so at half throttle (0.5). You post a sheet with the numbers you feed to the YaSim solver. When I worked with engineers from Eurocopter and Airbus, in their office, on the door was written: "Don't tell them it's impossible and they will do it". So stop coming to pollute discussions that don't concern you. That the speed is 150 kt instead of 155 kt on the real thing, they don't care completely, completely and definitively.īut pleasure is a notion that does not seem to be part of your life. The important thing is the pleasure that many take in flying, flying over scenery, piloting planes. A way of thinking that some will never be able to understand as they are megalomaniac and full of themselves. When I worked with engineers from Eurocopter and Airbus, in their office, on the door was written: "Don't tell them it's impossible, and they will do it". Once again a great proof of his desire to be lathered without ever questioning himself. That being said he looked, he saw inconsistencies but instead of correcting or indicating what to do he prefers to denigrate and criticize as always.
And he continues to drool in a discussion that does not concern him.
