A few years ago I made a simple jet motor out of coke cans and some other simple items. It worked… barely. lol
Here is an old plan I made for a Virtical Take Off and Landing jet motor, such as the pegasus used in the herrier jet. Basically, this juet motor would be classified as a medium bypass turbo fan with pre-combusion and post combusion thrust vectoring… a nice design, naturally. =) The jet would burn light oil, like kerosene.
