The word “pulse” and “engine” can be recorded back to somewhere around 1880-1890. And in the early 1900 a man in France build a pulsejet engine, but he didn’t get it into a reconance, only single explosions.

Almost everybody has heard something about the “Buzz bomb”, they know where it was used, and how terrible it was. That is true. Their sound spread horror across southern England during the Second World War. This “thing” was the Fieseler Fi 103 powered with an Argus AS-014 pulsejet engine. This aircraft was an unmanned bomb, steered by a gyro. When the fuel ran out, it just dropped down from the sky and explodes on the ground. But it was something wrong with the design, the engine was never supposed to die out before impact. Because this was a warning signal, when the “Buzz bomb” stopped, soon there would be an explosion.

But the Englishmen could defend them self from this weapon. It wasn’t fast enough for thier fastest aircrafts, so it was possible to hunt it and and shoot it down. It was also possible to shoot it down with anti-aircraftgun.

Why do we need pulsejet engines? We have operational jet engines, big and small and they run longer and more efficient that any pulsejet engine. That’s true, but you can’t build a lightweight jet engine that’s deliver 3-10 kg thrust easily in you garage. But with a pulsejet, you can.
So what do we use them for? Small engines are mainly used to give thrust to model aircrafts.

When you look at the material details you will think, “This must be a simple engine” but infact, it's a rather complex engine. It’s also difficult to understand the operation sequence.

So where do we begin? The first guy to understand the theories was the German Paul Schmidt. He was active from 1928 to later after the Second World War with his pulsejet ideas. Infact, he did not build the famous V1 engine, he just lead the Argus Company on the right track when they desiged the engine. He had a better and more efficent construction. But he didn’t reviel his secerets because he thought that he could make a profit out of his ideas after the war. But the turbine jet engine was at its dawn and the pulsejet engine never became the commercial succes that Paul once thought.
