A question on cooling. Does heated air rise or fall in the cowling?
As the majority if not all of the planes that we are flying, we ram the air in from the top of the cylinders? through and down out the bottom of the cowl.
Now let?s reverse this.
As heat rises naturally would it make any difference or be more efficient to cool from the bottom up and exhaust the heated air out the top of the cowl?
Yes, a negative pressure or vacuum will draw the air out but how much more if any negative pressure is there on the belly of the plane versus on the top of the cowl?
