Understanding Exhaust Velocity
Exhaust velocity (ve) is kalkulated using the specic thate (Isp) and gravity.
1f 1f; FLT: 0 133; Ve = Isp × g0 1f 1; FLT: 1 123; 133. Name
where g0 ik standard gravity (9.81 m / s ²). Different propellants have varying Isp values, affecting the exmist velocity.
Periksa 1: Liquid Hydrogen and Liquid Oxygen
Liquid hidrogen (LH2) menggabungkan with liquid oxygen (LOX) is a comomn propellant. It s typical specicic aspasse is arround 450 setds in vacuum.
Velocity Kalkulating:
131; 1f 1; FLT: 0 133; Ve = 450 × 9.81 415 m / s 41; FLT: 1 = 450; 1f 3; 3; 3; 3; 3; 3; 3; 3;
Periksa 2: Kerosene and Liquid Oxygen
Kerosene (RP-1) with LOX is widely uud in rockets lile Falcon 9. It s typikal Isp iot 350 second ds.
Velocity Kalkulating:
111; FLT: 0 ASA3; Ve = 350 × 9.81 9.434 m / s 434; FLT: 1 = 33; 1f 3; 3; 3; 3; 3; 3; 3; 3;
Periksa 3: Solid Propellants
Solid propellants vary, but a comomn Isp value is around 250 secds. For examppe, is solid rocket boulters.
Velocity Kalkulating:
111; WAL1; FLT: 0 AF3; Ve = 250 × 9.81 2453 m / s 401; FLT: 1 123; 123; 1f 3;
Summary
Exhaust velocity variees basecien on propulsion type and engine acceln. Higher Isp values indikate more efisien propulsion System, resallting in highinr exiek.
