Tu160 takeoff on one engine? maybe, with a looong runway, cold day,
and minimum fuel. 275000 kg gross, subtract 75000 for payload and
extra fuel, leaves 200000 kg to be pushed by 25000 kg. 8 to 1 thrust
to weight. I remember making mil power takeoffs in the F86D at 4:1 and
about a 5400 foot ground roll. looking at the math we have 200000/9.8
= 20408; 25000/20408 = 1.23 m/sec acceleration on takeoff. The rest is
left to the student as a drill.
