Don't laugh. I want to build a jet pack

Post by Temjin4 » Wed Jun 02, 2004 5:58 am

Wouldn't that be awsome. Where do you think I should start? Ive been searching this site and a couple of others and I want to try. It doesn't have to produce very much thrust. Im thinking 75 lbs or so. Thats using 4 jet engines. Which Jet engine should i use?
Cool stuff happens all the time. You just gotta be on the look out.

don't multiple post please, just clutters up the boards.
If you post one place, we are bound to see your question a first time. Other then that, welcome : o)

ok sorry about that. I belong to some other HUGE car forums and I know that people only look in their own catagory most of the time. Thank you for the welcome. Any advice at all?

Yeah. We ALL want a jet pack! That's why we're here! But we'll settle for a working engine for now...

Hummmm.... A jet Pack ....

Hummmmm ... A jet Pack ....

That not a bad idear ... What about four 130R pressurejet ... And and go sonic on your first test run ... He he he. If you don't run out of fuel before.

No ... Serious, I beleive the best engine configuration for a jet pack, is the lockwood design. But the problem you will find with all the engines here ... is HEAT.

For my part, I would select a chemical rocket configuration, for a jet pack design. They run cold all the way up to the nozzles and if they are far from you, you won't get burned.

In opposite to Patrick and I, where we have lost a few hairs and jackets also. And this, from a 3 feet distance ... He he he.

Ask Patrick ... We don't call him the flying man...We call him the Smoking man ... He he he.

Well ... That my advise to you ....

Cya ...

Hey All-
I've also been thinking of designing a jetpack but so far have just scribbles really, I guess I've seen The Rocketeer one too many times...

To cut down on heat you might want to try some exhaust insulation wrap on the outside and, if you're really serious, take it to a custom car shop and have them coat the inside with a ceramic heat shield (it's what they use on exhaust systems for high-end cars)

Also, I would suggest just one jet, all of the extra tubing and such will add up, you know what they say, ounces add up to pounds. Just for thoughts...

Which brings me to a question, in its simplest form, which jet produces a higher thrust to weight ratio?

Thanks,
Chris

theres a german guy doing this ... he calls it a "monocopter" but its a huge turbine plus some tubes... hes using a carbon fiber compresor (the wings are CF not the compresor itself) if i remeber the link will post...

Check this guy out. The picture is cropped on his new site, but he is using 8 AMT turbines........ or trying to. He used to post updates (lack of success) before he went to a flash site... He was selling naming rights for $10K on Ebay for a while (no takers) He has basically been amusement for the Jet Guys at RCU. and me to...

Well, judging by these pictures, he is not the only one contemplating the use of several micro-turbojets for a jet-backpack. Who knows; maybe it could even work.

You'd be one of only 10-15 or somthing like that to build and use one but it wouldbe so cool if it worked try read this artical

I wonder how long it would take to go deaf. I'm guessing no ear protection in the world could muffle all of those engines next to your ears.

The guy ay skywalkerjets.com has posted a test video from 4-6-06. Check it out, it isn't a pretty flight or anything, but it does lift his weight. He may just pull it off someday.
On an endless quest in search of a better way.

Would a graphite plate protect the user from heat? If not that maybe sodium silicate with carbon fiber lke the space shuttle uses!!

Everyone seems to think of the jets being head level, I would say this guy is the closest so far:

A big chemical rocket to get off the ground and some tiny retractable wings to keep you moving, no 007 type jet pack but transport that straps to your back...
