24 авг. 2021 г. · Delta-V tells you "how far" your rocket can go, measured typically in meters per second (m/s, velocity), but it can be measured in hm/h or in ...

22 окт. 2019 г. · Delta-V is a change in velocity. A rocket need a specific amount of change in its velocity to be able to do certain movement. So for example if ...

10 февр. 2022 г. · Your delta V is just how fast you could move relative to the potato if you spent the fuel in each of your stages propelling yourself in the same ...

22 сент. 2023 г. · Yet the specific impulse changes as the rockets gains altitude. So for example ,the Isp at T+5 will not be the same at T+50.

10 авг. 2024 г. · A simple answer: delta v only depends on the specific impulse (Isp; efficiency) of the engine and the ratio of propellant mass to total mass.

24 янв. 2015 г. · The equation relates the delta-v (the maximum change of speed of the rocket if no other external forces act) with the effective exhaust velocity ...

20 мая 2015 г. · Specific Impulse (ISP): Efficiency of an engine in either atmosphere or vacuum. Higher numbers are better. Some engines (the LV-N atomic engine ...

29 апр. 2015 г. · To calculate delta-v by hand for a single stage you use the formula (Specific Impulse * 9.81) * ln(Full Mass / Empty Mass). Specific Impulse can ...

28 мая 2018 г. · The honest answer: Delta-V is the total change in speed that's currently possible with the current amount of fuel at your current mass. I don't ...

29 июн. 2024 г. · Specific impulse can be given in seconds, which is can be thought of as how many seconds 1 kg of propellant can provide 1kg of force (9.81 N).
