A rocket is launched on a constant thrust mission in a vertical trajectory; g = 9.8 m/s 2 and dragis small compared to gravitational forces. The takeoff weight is 350 kN, the specific impulseis 300 sec. The maximum acceleration that the payload can experience is 7 g’s.Calculate the maximum velocity increment (Du) in m/s that this rocket can provide to thepayload, and if it gives this velocity to the payload, determine the mass of the payload and themass of the propellant. (Neglect the weight of the rocket casing, structure, engines, etc., sototal mass = mass of payload + mass of propellant)

Question
A rocket is launched on a constant thrust mission in a vertical trajectory; g = 9.8 m/s 2 and drag
is small compared to gravitational forces. The takeoff weight is 350 kN, the specific impulse
is 300 sec. The maximum acceleration that the payload can experience is 7 g’s.
Calculate the maximum velocity increment (Du) in m/s that this rocket can provide to the
payload, and if it gives this velocity to the payload, determine the mass of the payload and the
mass of the propellant. (Neglect the weight of the rocket casing, structure, engines, etc., so
total mass = mass of payload + mass of propellant)
