- For any given specific power, with a large which is desirable to save propellant mass, it turns out that the maximum acceleration is inversely proportional to .
- Bill Tee's propellant mass is pure, distilled water shipped up to orbit from Ganymede.
- In a dual-thrust solid fuel rocket motor, the propellant mass is composed of two different types or densities of fuel.
- According to the Tsiolkovsky rocket equation, a rocket with higher exhaust velocity needs less propellant mass to achieve a given change of speed.
- The theoretical exhaust velocity of a given propellant chemistry is a function of the energy released per unit of propellant mass (specific energy).
- In other words, the propellant mass fraction is the ratio between the propellant mass and the initial mass of the vehicle.
- However, for reaching orbital speed, hydrogen is a better fuel, since the high exhaust velocity and hence lower propellant mass reduces the take off weight.
- The hydrogen is heated by the fusion plasma debris to increase thrust, at a cost of reduced exhaust velocity (348-463 km/s) and hence increased propellant mass.
- This lack of a performance history in space meant that despite the potential savings in propellant mass, the technology was considered too experimental to be used for high-cost missions.
- A closely related (but different) concept to energy efficiency is the rate of consumption of propellant mass.
