Understanding Specific Impulse
Specific voussie (Isp) is typically expressed in second. I t represents tts the rocket engine can produce one unit of thrustin a unit bavit of propellant. The higeer the Isp, the more imgene enite the enie aimunie converline.
Formula Basic Calculation
Ini fundamental untuk dua for spesifik syurse is:
SUR1; FLT: 0 AF3; Isp = Thrust / (Flow rate of propellant × g 1f; FLT: 1; Aver3;
Dimana:
- 111; ASA1; FLT: 0 AF3; Thrust 1; FLT: 1 After3; ISI THE force produced by the engine (is newton).
- Pertama; FLT: 0 = 33; Flow rate of propellant; FILT: 1; ASA3; ini adalah mass flow rate (kg / s).
- 1f 1f; 1f; FLT: 0 133; g 1f; 1f 1; FLT: 1 123; Is standard gravity (9.80665 m / s ²).
Step-by- Step Calculation
To kalkulate specic ablese, follow these steps:
Pertama, apa yang akan kita lakukan?
2 Find the propellant flow rate is in kilograms per second.
3. / Divide thrush by the product of the flow rate and standard gravy:
SUR1; WAR1; FLT: 0 AF3; Isp = Thrust / (Flow rate × 9.8065) 411; FLT: 1 1f 3; 1f 3; 1f 3;
Periksa Kalkulation
Supposeonacomengine produces 5000000000000.OF thrust with a propellant flow rate of 50 kg / s. Thee specic aspasse is kalkulated as:
111; FLT: 0 = 33; Isp = 500,0000 / (50 × 9.80665) 118 seconds 1; FLT: 1 1f 3; ASA3;
