What is the maximum thrust an Ion Engine can achieve?

F=m*a, what is the force in pounds of thrust?

  • An aircraft with a mach # of 1, mass=2000 lbs, runway length of 2000ft, In theory or fact how much thrust does it need to achieve 800mph with in a couple minutes give or take. Engine wght and fuel is included in the 2000lbs. Use an average density.

  • Answer:

    It's physically not possible. If "An aircraft with a mach # of 1" means the max velocity is mach 1, it will never reach 800mph no matter how much thrust it has unless you could fly 15,000 ft BELOW sea level. http://www.aerospaceweb.org/question/atmosphere/q0112.shtml

If there is no friction, then you can use f = m x a where mass = 2000lb and acceleration is based on the time it takes to get to 800mph. From there you can solve for force (thrust). If you start to get technical, it's really a calculation of drag so it depends on the shape of the airplane and it's drag coefficient. It gets even trickier the faster you go because the air starts compressing and behaving differently (Mach No > 0.3). Then if that's not enough, as you approach mach, you start to generate shock waves which would require it's own amount of thrust. At the end of the day, it's a function of more variables than weight and speed.

it will require at least 2000 pounds of thrust to move.
