pictures for your enjoyment

Post by steve » Sun Jun 06, 2004 1:03 am

I have been monitering this forum almost daily for the last six months and during that time have built three engines. Recently I entered my engines as sort of a science fair project at a major technical expo in connecticut AND WON BEST IN SHOW!!!! essentially that means that I can get into any technical or engineering college in the US. I am writing this to thank you all for the helpfull information I have gleaned from this forum over the past months. I would also like to thank mk, whoose KP-T 01b dimentions I used for my seccond engine (everyone should build this engine!! It started on the first try and is so easy to build that even someone with little metalworking experience, like myself, can manage it).
And now, the pics:

I'll post movies If I ever figure out how to convert mpeg. to wmv. (any ideas?)

ps. please don't yell at me for not posting this in the off-topic section!

Nice pictures! Could you add descriptions for your pictures?

Looks to me like you're advertising Champion spark plugs hehe.

I should try this for next year's science fair too... Or as a school project...

On behalf of the rest of us PJ regulars, I would like to congratulate you on your success.

If you wish to, you could represent the beginning of a new generation of engineers who develop PJ technology into the next jet-propulsion discipline for the masses. Or, you could join the latest fad (being financed by the govt. and big corporate money)--the PDE.

I wish I were your age again--it's good times for propulsion engineering.

P.S.: When you get to college, don't belittle the English course requirement--you need it! (as do a majority of the participants on this forum).

Oh, yeah!--but your pulsejets are better.

Congratulations on some fine-looking work there; a good rule is, if it looks good it probably runs good too.

Did I misspell something?
anyway here are some more pictures of my third engine: a medium/large lockwood. I just ran it for the first time yesterday. (No noise complaints yet! I have very understanding neighbors) the plan is for my friend to build a seccond one of these and mount them both to a gokart we are building. When we are done playing with that, the gokart will be converted to a land sailer for some quiet fun.
And now, the pictures:
ps. can anyone give me the approximate thrust of this engine if the tailpipe diameter is 9.1 cm? I know a good rule of thumb was posted somewhere but I can't find it.

some dimentions for you
also not shown, the radius for the bend is 8cm, the arc length for the bend is about 25cm puls an extra 6cm between the bend and the combustion chamber.

Great work, Steve! One of the more impressive first appearances in the forum, I must say. You richly deserve all the prizes you have won.

Steve -

I want to add my congratulations also -- wonderful work! Yours is the kind of story I live for: the young experimentor making a go of something not all that easy to do, and being justly rewarded for making it work. Nice job on the photography as well.

All the best,
L Cottrill

I believe MK is mostly resposible for the KPT-01 and that someone else can simply build it from the one drawing is excellent. The size is almost ideal for home builders in respect that its large enough to take direct injection of fuel into the cc yet small enough for the boot of a car.
A superb effort all round.
I've started to build a light weight version but need a TIG welder.
I'm sure MK will not mind me reposting this on his behalf.
Regards.
Mike.

Remember M. tweaked the diameters and removed a chunk of tail on this one. He gets some cudo's too! ;-)

Indeed he does. As you can see from the well defined intake section (rather then the small flare pictured in the plans) I made use of these dimentional tweeks.
diameter are ID's, maximum rated thrust = 21 lbf (ca. 9.6 kgf);
I am happy and thankfull to finally have the answer to all my classmate's first question upon seeing the engine. I'm a little dissapointed though since I was optimisticly predicting between 30 and 40lbs thrust. Its a good thing then that I will have two engines on the go-kart, which by the way is nearing completion.
thanx again for your help

ps. yes I am aware that my spelling sucks

I was bored so I decided to post some more pictures for your enjoyment. I think you will especially enjoy the one taken when I demonstrated my big lockwood at school (look for the one girl who looks like she's screaming in agony hehe)

Nice stuff Steve. I like the girl's expression too. Might you be secretly working on a 6.5 inch pulsejet now, the shirt pocket collection?
