Performance headers work to increase the exhaustvelocity as much as possible. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For low exhaustvelocity with respect to the mission delta-v, enormous amounts of reaction mass is needed. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These values are used in equations similar to the rocket equation and are analogous to specific impulse or exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The efficiency comes from the high exhaustvelocity, which in turn demands high energy, and the performance is ultimately limited by the available spacecraft power. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For air-breathing jet engines, particularly turbofans, the actual exhaustvelocity and the effective exhaust velocity are different by orders of magnitude. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, for reaching orbital speed, hydrogen is a better fuel, since the high exhaustvelocity and hence lower propellant mass reduces the take off weight. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The first is the effective exhaustvelocity: the equivalent speed that the propellant leaves the vehicle. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, the effective exhaustvelocity allows for various losses, and notably, is reduced when operated within an atmosphere. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The combination of high particle energy/exhaustvelocity and relatively high thrust in this form is a novel proposal. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, the effective exhaustvelocity for the entire reaction drops to just 0.58c. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. While the actual exhaustvelocity is lower for air-breathing engines, the effective exhaustvelocity is very high for jet engines. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The actual exhaustvelocity is the average speed of the exhaust jet as it leaves the vehicle. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For rocket-like propulsion systems this is a function of mass fraction and exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This reheating of the turbine exhaust gas raises the propelling nozzle entry temperature and exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There is a mission-dependent limited optimal exhaustvelocity and specific impulse for any thruster constrained by a limited amount of onboard spacecraft power. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Larger ratio nozzles are more massive but are able to extract more heat from the combustion gases, increasing the exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This also means that rockets are able to exceed their exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Exhaustvelocity is best neither too low nor too high. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Note that different symbols are sometimes used; for example, "c" is also sometimes seen for exhaustvelocity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The exhaustvelocity of the ions when expelled by the ramjet was assumed not to exceed 100,000 m/s.
