| 11. | It is important that thrust and specific impulse not be confused.
|
| 12. | In this regard a propellant is more efficient the greater its specific impulse.
|
| 13. | Specific heat, specific modulus, specific volume, specific activity, specific impulse, specific fuel consumption
|
| 14. | The vacuum optimized version produces and has a specific impulse of.
|
| 15. | The YZ-1 has a thrust of with a specific impulse of 315.5 seconds.
|
| 16. | The benefit of this setup is increased specific impulse over that of a rocket.
|
| 17. | This arrangement would minimize the stage length, while keeping the engines excellent specific impulse.
|
| 18. | For instance, during lift-off thrust is a premium while specific impulse is less so.
|
| 19. | This gives it a higher thrust and specific impulse, but makes it longer and heavier.
|
| 20. | Black powder had a very low specific impulse, however.
