For some time I have been playing around with the idea of building an extenal combustion closed Brayton cycle engine, similar in type to those developed for...
i know that if u miX iron oxide and aluminium oxide it will burn at ½ the temp of a nuke reactor I would like to make a engine that runs on that?? Josh Bob...
You missed a bit in your chemistry lessons. The mix you describe will just sit looking at you. I assume you have remembered incorrectly the thermite reaction....
Actually, the temp inside a nuclear reactor is not as hot as inside our engines. A nuclear bomb on the other hand is for sure a scorcher!!! Fred ... From:...
OK Thanks, but I really don't have any problem about generating the heat. A nice liltle fire would do fine, but there are a load of other problems i thought...
One problem you will have with “normal” turbochargers is the RPM range they like 40,000 to 100,000 RPM depending on model. It is not simple to “gear” ...
I want to use Helium for the same reason it is used in Stirling engines. It improves the efficiency of the engine and reduces corrosion and oil degradation. It...
I didn't realise they went quite that fast. Do they have to run that fast? Is it something to do with needing to run that fast to overcome leakage past the...
True, maybe I put too much weight in that issue, but helium is expensive to refill all the same. It´ll be interesting to see how it turns out - maybe leakage...
Turbines are designed for a certain operating range, I’m sure you could extract SOME power at a lower RPM but I doubt it would be very useable. You keep...
... I have heard that axial turbine power is proportional to the cube of rpm. Perhaps it is the same for scroll compressors? It would be very useful to know...
Hi, the big problem with all the displacement alternatives to piston technology is the sealing. Even the Mazda rotary had problems for years. How do they...
Actually, the rpm needed to match the frequency of the local power depends on the windings of the generator. As is the case with motors, depending on the...
Reponses in-line below: Dan Nicoson * you were pressurizing the whole system thinking that equated to efficiency, ... Glad you bought this up. I accept...
hello all i have completed my jet kart and i am now going to sell it for money to start my next project. i will be selling it for 800.00 and it will come with...
... various fuel ... Coal & wood as I currently use. Using gas or oil would be better as I would be much better able to control the fire temperature to obtain ...
hello what is your new project eddy aaron <mr_bojangls2003@...> a écrit : hello all i have completed my jet kart and i am now going to sell it for money...
Hi, Try Garret (UK) for shafted turbos. Turbo shafts "float" on a thin film of oil that must be constantly replenished so there is no hermetically sealing....
This is the video that Chris sent me after playing with Turbitrac for a few days down on the south coast where he lives. I think he is very happy, it brought a...
Would an automotive turbocharger already be considered a turboshaft, as is? Or would further modification have to be done to it, to make it a turboshaft? If...
SNIP The design of a steam generator can give the performance you require for steam power generation. In fact it's been done. Cyclone Power has demonstrated...
Hi ?? The average DIY engine is going to be too heavy for a backpack , you need something like http://www.microjeteng.com/ If you're interested in producing...
Jet engines have pretty horrible fuel efficiency. A 2 stroke engine would most likely be much more suitable for "jet-pack" use. Also, with our turbo-based...
