Total Impulse Calculator

Formula

The formula to calculate the Total Impulse (Itotal) is:

\[ \text{Itotal} = \Sigma \text{Ft} \times \text{dt} \]

Where:

\( \text{Itotal} \) is the Total Impulse (N-s)
\( \Sigma \text{Ft} \) is the Sum of Thrust Forces (N)
\( \text{dt} \) is the Time (seconds)

What is Total Impulse?

Total Impulse is a measure of the total momentum change produced by a thrust force over a specific time period. It is commonly used in rocketry and propulsion systems to describe the effectiveness of a thrust event.

Example Calculation

Let's consider an example:

Sum of Thrust Forces (Σ Ft): 500 N
Time (dt): 10 seconds

Using the formula to calculate the Total Impulse:

\[ \text{Itotal} = 500 \times 10 = 5000 \, \text{N-s} \]

This demonstrates that with a sum of thrust forces of 500 N and a time of 10 seconds, the total impulse would be 5000 N-s.
