Well, I’ve bit the bullet and ordered 5 pocketjets, radically redirected so augmenters can be added, and just maybe put it in a twin jet model like F-18(?). Done right, I think this fella should do 6 lb thrust.

Re: Mike's Build Log
Yeah, I’ve been following that one. The fun in those articles is in the comments. :lol: HAV’s for firefighting is just silly. Just the issue of buoyancy management after dropping a load of water doesn’t get very far into the math. Our personal extensive experience with wildfires also points to very ...

Re: Mike's Build Log
Gawd, another year with not enough play. Anybody still watching, have a great holiday if you get one! I still dream of orange hot metal, and I still haven't done anything with the pocketjet I got to be an instant starter last Christmas. Lately, my daydreaming is about fanciful steampunk style airshi...

Re: ScrapQueen's turbocharger jet
Great news, about the job I mean. Any time I interview an engineer, the first question is "what are you making at home?"

Re: hey hey happy new year
Hi Simon! I still burn some fuel and make some noise, mostly when I want to fire up a young engineer-to-be. You building anything fun?

Re: Mike's Build Log
Gawd, I have to make time for more fun! Happy Holidays, those still watching his thread. I ran my 5 pounder on Saturday. I had to quickly figure out the auto start fuel again, since at the shop we got rid of our air compressor and switched to a nitrogen tank for blow off, which doesn’t work so well ...

Re: Scrap Queen's first foray into valveless pulse jets
That color and sound is addicting isn’t it? I’m all prepped to run one this Saturday.
Scaling from 50,000 feet: a good little motor will scale up, but scaling down is really finicky. That expansive tail makes it more so. If you start with a straight tail, this scale down will probably work.

Re: Possible to convert valveless to valved?
That said, both have similar acoustic geometries. I remember plotting out the acoustic length correction for the bell mouth of a valver, and it yielded the length you’d expect for a valveless intake tube. It would be a very interesting project, proving they are actually much more similar than one mi...

Re: Axial (inline Gluey pressure jet engine)
Very nice, Kevin! No hearing protection required?
Some time at home helped the project, I’m thinking.
