The buzz bomb was a pulse jet powered vehicle, no ramjet used.Ram Jet Engine
The jet engine that almost brought England to her knees during WWII.
Those old enough to remember WWII will remember the German Buzz bombs over England. It wasn't the sound of this weapon growling overhead, but when the growling stopped, that scared everyone to death. Because then it was on it's way down, to explode. It wasn't called a terror weapon for nothing. This plan is for a similar jet engine. It is also a BUILD AT YOUR OWN RISK plan. It is simple to build using hardwood patterns to form sheet aluminum. Most parts are off-the-shelf items. Some light welding is required, but it's mostly bending and forming sheet metals, And, be very careful firing it up, if something is wrong, it will explode!
Also pulse jets or ramjets don't explode. It's not a good description of a pulse jet.
I have never heard a ramjet "buzz".A buzz bomb "buzzed" because it had pulse jet mounted on it not a ramjet.
