Although this article refers to a <b>Pulsed Detonation engine</b> and that seems to be different than the Pulsejet. I was under the mistaken idea that the V-1 was powered by a Ramjet, but as you can see by the following article I pulled off the internet is a bird of a different feather. Pulsejets have been around since the 1940's, and were used as the propulsion system of the German Fiesler Fi-103, better known as the V-1 Flying Bomb. The V-1 used an Argus Pulsejet which produced about 300 kilograms of thrust, and had a pulse frequency of around 47 Hz. In order to get sufficient air through the Argus Pulsejet, the V-1 had to be accelerated up a ramp by means of a steam catapult, powered by T-Stoff (Hydrogen Peroxide) and Z-Stoff (Calcium or Sodium aqueous solution used as a catalyst for the Hydrogen Peroxide). The Argus Pulsejet was also used in other German aircraft such as the Messerschmitt Me-328. Ramjets and Pulsejets are often confused, but they are actually quite different types of propulsion. Whereas a pulsejet is reliant on a valve system to mix and ignite the air/fuel mix before combustion and subsequent ejection - all as a series of pulses, a ramjet is a very simple device which literally consists of an intake, combustion and nozzle system in which the cycle pressure rise is achieved purely by ram compression. Consequently a separate propulsion system is needed to accelerate the vehicle to speeds at which the ramjet can takeover. A ramjet is literally just a tube into which fuel is continually fed and ignited. The ramjet does not use a pulsed mode of combustion, but rather continuous combustion.

The distinctive noise it made due to it's propulsion is why they called it the 'buzz bomb'. If I’m not mistaken, this is what powered the V-1 in WWII.
