Meredith effect duct
WebThe idea that the NACA cowling produced thrust through the Meredith effect is fallacious—although in theory the expansion of the air as it was heated by the engine could create some thrust by exiting at high speed, in practice this required a cowling designed and shaped to achieve the high-speed exit of air required (which the NACA cowling was … Web7 dec. 2014 · The second was an untried cooling radiator design called the Meredith effect duct - a divergent - convergent duct with a radiator at its widest part.

Web2 jul. 2016 · My question is then, instead of trying to utilise converted automotive engines for aviation (as many have tried and may are doing) why not convert the two-stroke V-6 outboard? It would be lighter, even with a closed cooling system and radiators (better to use a constant loss spray bar & undersize radiator in a Meredith effect duct). WebEnvironmental Impact Assessment ...

WebThe "Meredith Effect" is really a very weak and inefficient ramjet. You compress air in the inlet duct, add heat and then expand the air. Any properly ducted cooling system has this. The question is: how efficient is it? On the Merlin, the system was pretty good. My analysis shows that at certain combinations of altitude, speed and power, the ...
