Question 1
Get spacecraft into space.
Move them around after they get there.
Change their attitude (Sellers et al., 2015, p. 17).
Question 2
Rocket thrust is the force produced by a rocket, propellant mass flow rate is the energy expended by a rocket to eject mass out one end at high velocity, pushing it in the opposite direction, while exhaust velocity refers to the speed through which gases leave a rocket’s nozzle.
Question 3
The ideal rocket equation is how much change in velocity that is got as a function of the amount of propellant used.
О”V = C ln (Minitial/Mfinal)
О”V = has units of m/sec
C = effective exhaust velocity
Minitial = vehicle’s initial mass
Mfinal = vehicle’s initial mass
Question 4
О”V = C ln (Minitial/Mfinal)
= 1950 ln (10000/500)
= 151.1
Question 5
The combustion chamber transfers energy to the propellant to create high-enthalpy combustion products.
A nozzle converts low-velocity and high-enthalpy combustion products into the high-velocity exhaust.
Question 6
A nozzle in a thermodynamic rocket converts the thermal energy produced by electrical, nuclear, and chemical sources into kinetic energy.
Question 7
Over-expanded nozzle occurs when flow exits the nozzle at supersonic speed and at a pressure that is less than that of the e...
