Rangie 10 Posted September 4, 2016 (edited) So, 1kv up to 3kv, not inductive but with a degree of capacitive coupling, 1/2" or so dia connector with an earth/grounded casing. Is it an evacuated device? In my world that screams GM tube or photomultiplier... :-D Compensating for solar radiation/ionic radiation?

fv1609 22 Posted September 4, 2016 So, 1kv up to 3kv, not inductive but with a degree of capacitive coupling, 1/2" or so dia connector with an earth/grounded casing. Is it an evacuated device? In my world that screams GM tube or photomultiplier... :-D Compensating for solar radiation/ionic radiation? Alec Alec the capacitive coupling is just an inevitability rather than a necessity. Not an evacuated device in fact rather the opposite. Not a radiation issue. Quote Share this post Link to post Share on other sites

Richard Farrant 34 Posted September 4, 2016 Cloud charging, to get benefit from the ozone rich atmosphere around 12km up? Quote Share this post Link to post Share on other sites
fv1609 22 Posted September 4, 2016 Cloud charging, to get benefit from the ozone rich atmosphere around 12km up? Interesting thought Richard, but everyone is thinking of exotic explanations. It is much a more basic problem concerned with flying at this altitude. Quote Share this post Link to post Share on other sites
wally dugan 17 Posted September 4, 2016 is it to do with the air mixture to the engine attitude Quote Share this post Link to post Share on other sites
Lauren Child 12 Posted September 4, 2016 Nope Lauren this is to do with problems encountered at heights above 12km Rightho, that's into the stratosphere then. Low air density. Maybe something to do with static buildup from convection around thunderstorms? Quote Share this post Link to post Share on other sites

Good thinking Lauren nothing to do with static but the problem comes from low air density, so the design of this device allows a system to be used that circumvents the problem by doing something in a different way.

fv1609 22 Posted September 4, 2016 is it to do with the air mixture to the engine attitude Sorry missed you there Wally. It is not to do with the engine air mixture itself, but how the air outside the engine causes problems & these devices seek to avoid these problems by doing some else differently.

Altering the air inlets to compress more air? or Altering the wing shape/angle to provide the same lift in less dense air? Not sure why they'd want such a high voltage to do either though Edited September 4, 2016 by Lauren Child Quote Share this post Link to post Share on other sites
fv1609 22 Posted September 4, 2016 Altering the air inlets to compress more air? or Altering the wing shape/angle to provide the same lift in less dense air? Lauren this is how something behaves in less dense air & how it effects propulsion rather than aerodynamics Quote Share this post Link to post Share on other sites
