Sentence examples for specific impulse from inspiring English sources
noun
The ratio of the thrust produced by a rocket or other jet engine to the rate of use of propellant.
Four performance parameters are defined to evaluate overall performance of the two-phase underwater ramjet systems: transmission efficiency, propulsive efficiency, overall efficiency and specific impulse.
Thermochemistry, prediction of specific impulse.
The highest specific impulse reached 1640 N s/kg.
An average specific impulse of 3.4 6.9 s is measured.
Several mitigation methods have been compared by their specific impulse.
The fuel-based specific impulse can reach around 7000 s.
While it doesn't generate enough thrust to get a rocket ship off the ground, once you're in space, those high-specific impulse numbers mean the Neumann Drive can move a vessel very efficiently.
With a high specific impulse, the Neumann Drive can push through space using less fuel, allowing rocket ships to be lighter, and hold more room for cargo.
In addition, these metalized propellants offer increases in the overall energy density of the fuel and increase specific impulse, and they effectively reduce the tank storage volume.
Instead of relying on chemical reactions like conventional rockets, Dr. Chang-Diaz's creation, the Variable Specific Impulse Magnetoplasma Rocket, or Vasimr, uses radio waves to heat the fuel and magnetic fields to direct a stream of ultrahot ionized gases.
Argon is being used as a propellant in the development of the Variable Specific Impulse Magnetoplasma Rocket (VASIMR).
