The first (and so far only) major practical application of the pulse jet principle was in the German V1 Flying Bomb late in World War II; there are reports of pulse jets being used as part of hand-held devices in the 1950s to spread insecticide.
Pulse jets have a very high thrust-to-weight ratio and need very few moving parts, so they are cheap and easy to manufacture. However, they have poor high-altitude performance, bad fuel economy and they produce massive vibration and are also very noisy, which explains the nickname of "buzz bomb" that the V1 gained.
Pulse jets are mainly used today in model airplanes, though some experimenters continue to work on improved designs, including pulse detonation engines.
