Calculate the vehicle velocity increase under gravitational/Chemical Engineering
An arcjet delivers 0.26 N of thrust. Calculate the vehicle velocity increase under gravitationless, dragless flight for a 28-day thrust duration with a payload mass of 100 kg. Take thruster efficiency as 50%, specific impulse as 2600 sec, and specific power as 200 W/kg. This is not an optimum payload fraction; estimate an Is which would maximize the payload fraction with all other factors remaining the same.
