HOTOL - Anatomy of a spaceplane engine

HOTOL was a 1980s British project to build a totally reusable Space Shuttle. The project was cancelled and as it existed in the pre-internet age it's hard to find information about it.

In this video, with the aid of an original patent, I go back to basics to explain how HOTOL's unique rocket engine would have worked.

The patent referred to in the video is available here:

For an explanation of why I think SSTO spaceplanes are the future of space travel check out my original spaceplanes video:
