How would I make mini jet engine turbine blades at home?


I want to make a mini turbojet at home. What good manufacturing techniques at home should I use?? And again, how do I make the turbine blades?

first you need very precise mold(s) in the shape of the blades. I would say use one mold only to make 4, 6 or 8 very similar blades.

You then need a way to prepare the finished blades for exact balance.

Perfect balance is needed, because imperfect balance would vibrate a connecting shaft, then vibrate an engine, which could lead to engine or blade failure at very high speeds.

next you need very pure carbon and a slow curing epoxy.

Mix the carbon and epoxy and pour into the mold. Level out the mold and somehow mark or remember up to what level you fill the mold. Or engineer the mold so that it fills in the same for every blade.

As for how much carbon and epoxy to mix..that would have to be researched or done by trial n error. I would suggest starting at 50/50 or 75/ 50 carbon to epoxy. I know from experience though that high amounts of epoxy cause more an object to be heavier.

Pls let me know what u come up with...post ur findings in comments.

Finally the blades need to be housed, for forced directional purpose, and to protect the user from failures.

What would u use to power your minijet? Look into RC engines. Then decide on fuel or electric. Electric would weigh more and need more lift, while fuel use will be lighter but danger of explo_sion.

Has a jet engine/turbine been invented that can give a greater thrust than its weight?


In other words, a gas turbine that with a fuel supply can lift itself straight into the air? If there is, what are they called and provide some information. Thanks.

A "pound of thrust" is equal to a force able to accelerate 1 pound of material 32 feet per second per second, the equivalent to the acceleration provided by gravity

A jet engine that is of producing 1 pound of thrust, could hold 1 pound of material suspended in the air, if the jet were pointed straight down.
So, a jet engine producing 5,000 pounds of thrust could hold 5,000 pounds of material suspended in the air.

Honda HF120 Turbofan has a thrust of 2,050 lbf and weighs less than 400lb , It could suspend 1650 additional pounds in the air

Any jet engine that produces more thrust than the weight it is lifting can go straight up

    …risk the running out of gas equals the buildup from the tank going in your carb, going to have to clean the carb (s) and get fuel back to the chamber.
    Good luck and fun again bro…

    You might get a good answer to this question if you post it in Cars and Transportation under the Aircraft category. People browsing there often give good answers to such questions. Best of luck with getting the information you need.

    There are countless computer chips available – to the best of my knowledge, unlike GM, Fords do not have a plug-in eprom or prom chip in their ECM. The performance chip has to be outside the ECM.
    I can only suggest that you buy a good brand that's guaranteed – that way, if you encounter any problems, you can get support or, at worse, return it.
