Hi everyone,
I just have to post something up on this one.
This is the new engine in progress after over 2 yrs of work.
Pruuuudy!
Shiiiiny!!
I am going to have trouble, with maybe a tear when i first set this sucker on fire.
More to come... just do not ask me for plans.

Sooooo shiney, soo very very nice rossco. I love the look of stainless, I had a sneak peak of how it will look when finished, so i had ample time to pick my jaw up off the floor. Good to see you making it in stainless, its gonna look sweet.
Best of luck.
James.

Mike Often wrong, never unsure.

Not so shiney
Finished build and some short runs a couple of days ago.
The tail pipe needs to be larger in diameter, this is just what i had at the time. It is not breathing properly as it is.
Here are the results to date:
IT RUNS

- SLI second run shortened tail.wmv
- Ear muffs good idea!
Just a short run after the tail was cut... yes, very roughly.
Very sub optimal injection, purely making sure that it will run. - (1.99 MiB) Downloaded 2665 times

- Latest SLI very first run.wmv
- Hot of the press, feed fire and see if it will run. Yes, that last bang hurt!

Mike that is my living room! Can't you tell from all the Junk lying around?! LOL.
Now I was lucky enough to witness this SLI run for the first time in stainless, and was very impressed by rosco's starting methods. I tried but couldn't even get it close. The engine itself ran very well, rosco even cut some of the tailpipe off and it ran even better. The most interesting thing about this engine is you think its stopped, and you walk over to then all of a sudden BANG! I can't explain it, but its hilarious, scary at first though, and painful... engine stopped, earmuffs off, walk over... boom...kick engine. Theres no mistake about the amount of air its pushing, crazy.
Kudos to you rosco, it does look nice in stainless, and whatever that medical grade stuff was it certainly wont rust anytime in the next 6000 years, so its a keeper. All in all I'm really happy for you, a real success on the design front. Good work, I look foward to the day you get a thrust reading.

Man, that is a beautiful piece - and runs nicely, as well. Congratulations, sir!
You might do a YouTube video, featuring Haydn's "Surprise Symphony" in honour of that delayed bang on shutoff ;-)

Thanx guys, ive been needing some drive and support in this project for a while, its not as much fun as it was in the beginning.
Ive just been going through some of my old videos of this beast over the last year or so.
Ive done some crazy things with it.
Here is an old vid of the last model. I still get a laugh out of this one.
What a thrust stand that is! Just strap your engine to an old steel box it can push around.
The smoke, as it seems the first question everyone asks, is from a slieve in the tail. I had a whole bunch of different tails for it, and put a heap of grease on every time so i can get it apart again. On that particular tail, it didnt seal very well, hence, the exessive smoke.
Attached also, is a pic of a selection of tails.
This engine at that stage also had too small a tail pipe diameter. This was about the revalution in CC pressure peak theory.
The larger tail section gives the intake the higher peak pressure that it needs to initiate, although over a shorter amount of time. These engines pump a fresh charge well before the CC is bellow atmospheric pressure.
YES, that is not just the "jet juice" talking! (James and i have coined exess jet fume inhalation as this)
It pumps from lower pressure to high! I am not getting something for nothing here, nor am i breaking the laws of phisics, I just have an agreement that they do what i want them to!
Well, any further and i would have to show too much!
Which... im thinking of doing! The whole public disclosure thing.
Any comments?
Glad that some enjoyment has come from the vids anyway, its been a long time coming.

- Detachable tail... slip the tail on the engine...grease or they dont come off again and yes, that helitail did work (most of the energy went at the "Y" tho), some balancing or even symetry would have helped a lot!.

- Model before this stainless one. Small tail, this went to 80mm dia in the end.

Dear Rossco.
So glad you've got that thing going.
Now what would happen if you stuck the important bits from that motor onto one of the VIII variants?
It may be a way to reduce the fuel consumption?
Regards
Graham.
Hope to speak to you soon.
