what about radial turbines? wouldn't they generate more torque than thrust? also read somewhere that radial turbines are better at lower speeds.
can anyone give more details on transmission design of turbine powered cars and motorcycles?
how very stupid of me. another thing, can you tell me if the indivudual particles of phosphor are at micro or nano scale? if they they are nano sized and embedded (closely packed) in a plastic sheet, would it be transparent.
now that i have a clear idea of piston seals, i have real doubts regarding how seals are maintained in wankel engines. if there is no force pushing the apexes and side seals, how are they sealed properly?
then again, if piston heats up more and expands more, wouldn't it create enough contact stress?
you might argue that it would need precise clearances, but wouldn't you need that for seals as well?
that is what my doubt keeps coming back to. whatever function the seals are serving, could be...
yes, but wouldn't there be much less of a difference if both piston cylinder were made of cast iron? isn't that why cast iron is used in the first place? because it retains shape/size even under high temperatures? if a cast iron seal can make up for expansion difference between piston and...
Re: pisotn seals
ok i get it.
but what about the gaps in piston seals? do they seal off by expansion?
the seals themselves are manufactured with that clearance. would manufacturing costs really increase that much for making pistons and blocks of desired clearance?
as far as i understand, piston have cast iron seals because of the properties of cast iron, which make it a sealing material. but i was wondering, if the cylinder and piston are both made of cast iron and closely fitted together, could we avoid using seals all together?
friction doesn't depend...
wow, so many people confessing to having dreams of the future and deja vus. i have a few questions to all of 'em. doesn't really mean anything, just trying to see what's common-
have you taken a proper IQ test, if so what was your score?
have you been diagnosed with an autism spectrum disorder...
are the 'vanes' of a rotary vane engine a major disadvantage? granted that the vanes would be under considerable stress, but is it so much larger than the stress on connecting rod in reciprocating engines? and is sliding friction on sides very high compared to pistons? also, is sealing a major...
