Force of a jet engine

  1. Feb 5, 2017 #1
    Hi
    Does someone know realistic numbers that i can put in this equasion so i can calculate the force?

    lucht = air
    brandstof = gasoline
    uitlaat = exhaust

    But what is vluigtuig?

    So to make it easier to read:
    $$ F = m \cdot \frac{d \vec{v}(t)}{dt} = m \cdot \frac{v_2-v_1}{\Delta t}= \dot m v_2 - \dot m v_1=((m_{air}+m_{gas})\cdot v_{exhaust})-m_{air}v_{plane}$$
    and you're looking for realistic figures for the various variables? Have you tried to find some information directly on the manufacturers' websites, i.e. RR and GE?

    At least, it might be worth an attempt. However, I thought about looking for some technical specifications of their products. Maybe they are available online. Or on some Wikipedia pages about jet engines. (If you swap between different languages on Wiki, you improve your odds, as these pages aren't 1:1 translations. At least our many different languages here are good for something. :wink:)

    Or google "technical data jet engine". Just some ideas.
