* Specific impulse, represented by I < sub > sp </ sub >, a term used to describe rocket and jet engine thrust

* Specific impulse: 1, 100 – 1, 600 s

Specific impulse ( usually abbreviated I < sub > sp </ sub >) is a way to describe the efficiency of rocket and jet engines.

Specific impulse and effective exhaust velocity are proportional.

Specific impulse is a useful value to compare engines, much like miles per gallon or litres per 100 kilometres is used for cars.

Specific fuel consumption is inversely proportional to specific impulse and effective exhaust velocity.

* Specific impulse

This increased fuel consumption offsets somewhat the savings in oxidizer mass ; these losses are in turn offset by the higher Isp ( Specific impulse ) of the air-breathing engine.

As noted the specific impulse of monopropellants is lower than bipropellants and can be found with the Air Force Chemical Equilibrium Specific Impulse Code tool.

* Specific impulse

* Specific impulse

Specific impulse ( Isp ) measures how much thrust can be derived from a given mass of fuel, and is a standard figure of merit for rocketry.

Specific impulse values from 200 seconds to several thousand seconds are possible by choosing the propellant and laser pulse characteristics.

* Specific impulse: 305 s.

* Specific impulse

* Specific impulse, the change in momentum per unit mass of propellant of a propulsion system

Specific facial and nasal evaluations record the patient ’ s skin-type, existing surgical scars, and the symmetry and asymmetry of the aesthetic nasal subunits.

Specific ethical behaviors originate in the Old Testament ’ s Ten Commandments, and are enriched by teachings in the Psalms and morals contained in historical accounts, see also Biblical law in Christianity.

Specific storage ( S < sub > s </ sub >) and its depth-integrated equivalent, storativity ( S = S < sub > s </ sub > b ), are indirect aquifer properties ( they cannot be measured directly ); they indicate the amount of groundwater released from storage due to a unit depressurization of a confined aquifer.

The ELA can be used, along with the Specific Infiltration Rate ( s ) derived using the LBNL infiltration model, to determine airflow rate through the building envelope throughout the year.

Specific health outcomes may also be difficult to quantify, thus making it difficult to compare all factors that may influence an individual ’ s QALY.

Specific activities involve securing " last-mile connections " and upgrading existing connections to the telescopes, updating the correlator to process up to 16 data streams at 1 Gbit / s each in real time and research possibilities for distributed computing to replace the centralized data processor.

Specific storage ( S < sub > s </ sub >), storativity ( S ), specific yield ( S < sub > y </ sub >) and specific capacity are physical properties that characterize the capacity of an aquifer to release groundwater.

Adorno ’ s 1949 dictum —" To write poetry after Auschwitz is barbaric "— posed the question of what German culture could mean after Auschwitz ; his own continual revision of this dictum — in Negative Dialectics, for example, he wrote that " Perennial suffering has as much right to expression as a tortured man has to scream "; while in “ Commitment ,” he wrote in 1962 that the dictum " expresses in negative form the impulse which inspires committed literature "— was part of post-war Germany ’ s struggle with history and culture.

He argues that it is possible to distinguish the moral impulse of utilitarianism, which is “ to define the right as good consequences and to motivate people to achieve these ” from our ability to correctly apply rational principles which will among other things “ depend on the perceived facts of the case and on the particular moral actor ’ s mental equipment .” The fact that the latter is limited and can change doesn ’ t mean that the former has to be rejected.

Hall thrusters are often regarded as a moderate specific impulse ( 1, 600 s ) space propulsion technology.

Hall thrusters are able to accelerate their exhaust to speeds between 10 – 80 km / s ( 1, 000 – 8, 000 s specific impulse ), with most models operating between 15 – 30 km / s ( 1, 500 – 3, 000 s specific impulse ).

For discharge voltages of 300 V, the ions reach speeds of around 15 km / s for a specific impulse of 1, 500 seconds ( 15 kN · s / kg ).

This design increases the specific impulse to about 1000 seconds ( 9. 8 kN · s / kg ), allowing for thrust-to-weight ratios greater than 1: 1, although at the cost of increased complexity.

Although less efficient than the open-cycle design, the closed-cycle design is expected to deliver a rather respectable specific impulse of about 1500 – 2000 seconds ( 15 – 20 kN · s / kg ).

The design provided 73 kN of thrust and operated at a specific impulse of 875 seconds ( 8. 58 kN · s / kg ), and it was planned to increase this to 975 with fairly basic upgrades.

can be calculated from the specific impulse, I < sub > sp </ sub >, where ( when I < sub > sp </ sub > is in seconds and g < sub > n </ sub > is the standard, not local, acceleration of gravity ), Using the J-2 on the S-IVB as a baseline design, we have P = ( 1014 kN )( 414 s )( 9. 81 m / s < sup > 2 </ sup >)/ 2

Robert Winglee, who originally proposed the M2P2 technique, calculates a specific impulse of 200 kN · s / kg ( roughly 50 times better than the space shuttle main engine ).

However, considering the mass of the source of the photons, e. g., atoms undergoing nuclear fission, brings the specific impulse down to 300 km / s ( c / 1000 ) or less ; considering the infrastructure for a reactor ( some of which also scales with the amount of fuel ) reduces the value further.
