Technically a pulse jet, wonderfully simple yet very noisy way to get thrust out of bits of scrap. There used to be a Dutch team that flew model delta aircraft with them on, insane noise and speed. They are, of course, banned for use on model aircraft in the UK.
Shame they had the terrible soundtrack on the vid, the noise of these things is quite unique.

I wish. The model specific ones can be found on the bay from time to time, or you can make one from an aerosol can, apparently..

I have a classic Dynajet 'Red Head' pulse jet. It has everything that a pyromaniac dreams about: inflammable liquids, huge flames, glowing metal and noise, lots of noise..
The ignition system is a 'trembler' circuit which generates a HT spark in the combustion chamber. Energetic pumping of a track pump forces air over a venturi, drags petrol vapour into the combustion chamber where after a few pops and bangs the pulse jet howl, if you're lucky, starts up. Awesome
The neighbours tend to disagree with my definition of fun but by the time they're mobilised the garage door has been pulled down, engine silenced and there's no sign of the unsilenced large block V8 that they imagine to be the source of the noise....
The engines are still used in model aircraft in the UK in the control line speed discipline. They hit speeds of around 200 mph with a 'pilot' hanging onto handle at the other end of the wires spinning around trying to keep up with the rotations. It's an awesome sight.
Here's a video of a pulse jet engine strapped to a control line speed plane. The engine is more or less identical to the one that I have but is quieter because it is operating in open air and not using a garage as a resonator box.

lol does the man in the middle get dizzy? We used to do that with a broomstick and see how long we could stand up for

You focus on the plane rather than the background to reduce any dizziness,I used to fly
Team race back in the 80's.
The planes aren't as fast as the pulse jet,still around 100mph though and there's three of you

Pulse jets are excellent! And excellently loud.
We had one running in the car park at work a while back. Not attached to a vehicle, sadly...
