Specific alpersé is a key paragorr is rocket propulsion thatt of efolciency of a rocket engmin. Ini mengindikasikan bahwa semua itu adalah propulterius pec unit of propullant consullend over enme. Understanding and trairing specicicidec e oxiscumfice.

Apa itu Specific Impulse?

Specific alpersé, of ten denoted as is expressed in second. Ini mewakili orang yang mengalami rematik rocket engine can produce one one of thrust froulum given otres.

Calculating Specific Impulse

The basic formula for specics syurse is:

SUR1; FLT: 0 = Ll3; Isp = Thrust / (Flow rate of propellant × g0) Syon1; FLT: 1; Aver3;

Dimana:

  • 111; ASA1; FLT: 0 AF3; Thrust 1; WHI1; FLT: 1 After3; ISI THE force produced by the engine.
  • Pertama; FLT: 0 = 33; Flow rate of propellant; FILT: 1: 1 After3; ini adalah mass of propellant excelled per second.
  • 1f 1f; 1f; FLT: 0 133; 133 = 33.5m / s ² FLT: 1: 33.3; ini standard grasy (9.80665m).

Alternatively, Isp Car Be derived Fromm Expansst velocity:

111; WAL1; FLT: 0 AF3; Isp = Exhaust velocity / g0 1; FLT: 1: 13; Aver3;

Importance in n Mistroon Planning

Knowing specidec the vocesser estimates the postimates of propellant needed for a mivanon. Ini influences ther of the rocket, including size, bobot, and fuel rementations. Higher Isp metries enecer longer misionals or resurset hadit.
