Back in the '80s I worked at a company that made model pulse jets, Curtis Dyna Products. They called them Dyna Jets. They were indeed *loud*. Hearing protection was a must. A university bought some of them from us to use as experimental sound sources in their experiments to sonically sterlize soil. I never heard how those experiments worked out.

[@TheDamiensdad]

I still have two old dyna jets that were my grandpa’s. He used them on competition speed ships. Basically control line “planes”. I know one is complete but one is missing a few things.

[@MalcolmCrabbe]

Remember going to Wings and Wheel every year back in the late 80's and seeing these strapped to a delta wing plane.. I think it was something like "ghost squadron" team that flew them... certainly were show stoppers, with everyone, including those in the beer tents stopping to watch them fly.. sadly complains from the old folks home some 2 mile away meant that they got banned from flying them as subsequent wings and wheels shows...

[@Matthew.Morycinski]

This noise can sonically sterilize people no? 😉

[@rollin18wheels]

I remember those very well. My dad did the whole RC aviation thing when I was a kid and I remember guys showing up at the RC airport with Dynajet powered planes and how astoundingly loud they were and how they would echo off of the tree line a mile away

I run mine on LPG. its a bit bigger and made from stainless steel, but has no reed valves to worry about. the supports are unable to stop the thrust from moving it, so I need to sit a few bricks on it, but yours is amazing, esp the cherry red heat.

I never saw one flown, but some of the members of the club had seen them and told me about it. When I remember the most is them telling me these pulse jets were *LOUD.*

[@sempertard]

Made a valveless PJ out of titanium a few years back. It's about 38" long with a 6" combustion chamber. I use propane to fuel it. Much easier to start and with valveless PJs you throttle them way back. Anyway, I start it with a Campbell Hausfeld 20 gallon direct drive air compressor. You know, the REALLY loud obnoxious ones. At full throttle, the PJ is so loud it completely swamps out the air compressor, to the point where you can't even tell it's running. I can feel my chest cavity resonate with the jet. Yeah... They're loud.

[@ErtsenPlayGames]

15y ago i build few super small ones , smallest one used 7.62 shell second one was 12g co2 bottle from asg (both needed sustained rly small amount of airflow to work- i used for that air pump from blood pressure monitor) ---- they were so loud that neighbours were annoyed when i turned them on

You might want to add a cross brace on your uprights. At that height your current stand might make the bearings less efficient and the readings could be well off.

I notice that the root of the slot between reed blades has a square end. This gives 2 stress riser points which could cause reed failure at the thinnest point of the blade. Try leaving a radius at the bottom of the slot. This should prolong reed life.
