Finding Delta V of a Rocket: An Overview

Click For Summary
SUMMARY

The discussion focuses on calculating the delta V of a rocket, which is defined as the increase in speed during the main rocket's burn. A specific value of 1 km/s is mentioned, indicating the speed just before the main rocket ignites. This value is noted to be over twice the Earth's rotation speed, raising questions about its origin and relevance in the delta V calculation. The conversation highlights the importance of understanding the energy dynamics involved in rocket launches.

PREREQUISITES
  • Understanding of rocket propulsion principles
  • Familiarity with delta V calculations
  • Knowledge of orbital mechanics
  • Basic physics of energy and speed
NEXT STEPS
  • Research the principles of rocket propulsion and thrust
  • Study the Tsiolkovsky rocket equation for delta V calculations
  • Explore the concept of escape velocity and its relation to delta V
  • Investigate the effects of Earth's rotation on launch trajectories
USEFUL FOR

Aerospace engineers, physics students, and anyone involved in rocket design or launch planning will benefit from this discussion.

I am doing an assignment about launching a rocket and at the moment I am looking for the delta V of the rocket. I have done a few researches and i found a method of finding the energy of the rocket and find the delta vee of it , but then i found this article and I am not sure if it is delta vee or not, and i don't get why there is a 1km/s in the equation

hi marco12345a! welcome to pf! :smile:

∆v is the increase in speed while the main rocket burns

1 km/s must be the speed just before the main rocket starts to burn

(but i don't know where that comes from … it's over twice the Earth's rotation speed :confused:)
