A nice idea! Although the configuration has some drawbacks:

- the low number of compressor stages can not provide sufficient pressure ratio

- the design can not deal with the surge problems occuring during throttling down and up (compressor is the most difficult part of today's turbines)

- every stage needs bearing and very high quality to ensure

- the most probably difficult sealing between the stages

- the temperature difference cause high stress to the material of the blisks.

Thanks!

Neat idea but there maybe too many gas leakage between rotors. Keep up!

It will not work. Something stupid, several problems. Air has mass and can not be placed in a zigzag pattern, without great loss of energy, besides the great warming problem does not occur in conventional turbines which have a structure, in which cold air is used to wrap the burning of fuel, preventing fusion of the moving parts. The turbine has a length to print the displacement of longitudinal velocity exhaust. Inventor of trash could end up being recognized as insane. Gilson

Another problem will be the turnover from your gaz. your compressed air is ignited with fuel in combustion chamber and it have to tur to the turbine blades. quite impossible without diffusor. But i think it's a nice idea

[Morbac88]

big problem will be the temperature difference between Compressor and turbine elements. To much stress will quikly cause craks into your blades, cuz, if i understand it there will not be vanes? so nice idea but i think it's utopic

a GAS turbine WARNING: DO NOT USE THIS IN A SMALL ROOM IT WILL GET VERY STANKEH IN DERE

Interesting video. Judging by your explanations, you must be a university professor. Need more basics and info on how this works than this PowerPoint presentation.

of course ur aware, 180 deg changes in airflow direction and lower RPM sap efficiency, and combustion chambers as shown would snuff out...but perhaps the most compelling feature is it's "shorter" stages. So you're intentionally trading off efficiency etc. for compactness? Also ball (?) bearings in rotors will add maint cost? the novelty is quite funny, though, because even though it'll "suck", prototypes might actually run.

[arthursulit]

also compressor and turbine typically need 3-5x more RPM than duct fan for hi BPR in typical op region. mass and width of duct fan would limit prolly <2800 RPM, and the few stages shown would mean the compression ratio of primary air wouldn't be anywhere near 40:1, even assuming no leaks. But mite work for other low speed lover noise apps like hover cars? Forgive if I'm missing something: I'm just an ex Navy av civ.

Good concept, but decades of trial and error doesnt exactly get pushed aside by a few drawings done on paint
