space whoosh effect

Hello!

I am completely new and I don`t know a lot about audio processing so please be kind for me.

How to create whoosh/space whoosh/jet whoosh/artificial jet/rocket flyby sound effect in Audacity?

I would like to use it as youtube soundtrack especially for subtitles cross fading in/out display.

I have purchased some wav samples and I can use them commercial use so I can modify them too.

Please help
I will really apprieciate it.
