Hello guys

How did you find PF?

via Google search when searching for astronomy and space exploration problems

Hi everyone, I've been visiting the forum for years. It can always surprise me when it has the answer or at least a discussion for my highly speculative or daydreaming scenarios (by far the favourite: external scramjet aerospike engine). And this time after I've searched for hours and found nothing, I thought I could just ask it here.

Welcome to PF.

It sounds like it would fit in the Aerospace Engineering or Mechanical Engineering forum. Start a thread there with links to your reading so far, and hopefully we can help you figure out your questions.
