16 нояб. 2022 г. · Honestly, I'd ignore the total impulse and start with the thrust instead. Take the rocket thrust equation. Thrust=˙mVe+(pe−p0)Ae. |
6 янв. 2015 г. · You take the effective exhaust velocity and multiply it by the mass flow. That gives you the thrust. Multiply that by the operating time and you ... |
15 февр. 2018 г. · You add the two thrust numbers together. |
28 янв. 2020 г. · "specific impulse" is the total impulse you can get from a unit mass of propellants. Total impulse is just force times the duration of the force (time). |
7 окт. 2020 г. · It is the amount of change in velocity (momentum) you can impart to the vehicle. The total fuel capacity is, ultimately measured in Delta-V. |
30 дек. 2019 г. · Thrust in newtons is equal to the propellant mass exhaust flow rate in kg/s times the specific impulse in N·s/kg (which is dimensionally equivalent to m/s). |
6 сент. 2018 г. · By definition, it is the total impulse (or change in momentum) delivered per unit of propellant consumed [1] and is dimensionally equivalent ... |
29 окт. 2019 г. · Specific impulse is a measure of the fuel efficiency of a rocket engine. It's established by the design of the engine, not by the size of the rocket. |
