V1 Pulse Jet Restored Test Video

Here’s a link to a Youtube of some friends of mine perfecting the starting technique of a scale pulse jet.
This thing is crazy loud!
For the sensitive, beware that their is an “F”bomb uttered after the thing shuts down.
Kind of understandable 😉 It was pretty exciting.
It later got installed on a delta shaped model.
We had to use a launch ramp to get it airborne.
The flight did not end so well. (kinda with a “whumph” in to a plowed field)
Mike claims that it will fly again. The engine was not damaged:)

Ta!

I was under the impression that the V1 engine required air going into the intake – that the aircraft/bomb needed to be travelling at a decent pace in order for the engine to work. Hence the need for the launching ramps.

Am I confused?

By the way, that thing is scary!

Ramjets need airflow: this is a pulsejet and is less dependent on airflow to function. If you look at V1 videos you’ll see that the engine is running before launch. The ramp was just an expedient way of launching them.

They ran a full size one on a trailer along the crowd line at Chino a few years ago. That was a rather deafening attention getter…

Here is a pulse jet that you can run at home:
