Overview

When you enter the puzzle, you find two rooms. In the front room, there is an angled fan with detachable blades that is pointed at a high ledge on the rear room. There is an inverter available, and a swapper with a hexahedron in it. There is a blue emitter behind a half-height grate. There is a purple barrier that leads to the rear room. In that room, we can see a driller and another swapper with an accumulator on it. On the right side is a blue door that is blocking access to the progress wheel, and a red receiver behind it.

Hints

A basic hint:

[ hint ]

Since the name of the puzzle is Propulsion, you might think that you have to use the fan to travel between the rooms quite a lot. You can do so if you want, but it is a bit of a red herring: until the end, you don't use propulsion a lot, but you do it at the very end.

If you're struggling to get started:

The first thing is to obtain a source of red light.

Try not to use the fan to travel between the rooms at all, until you're ready to open the door to the progress wheel.
