Anyone ever calculate the exact displacement of a full length 6'' PSP AeroPort?

[av8ter 10+ year member]

I am about to design a box 2 15'' RE HCs and would like to get to 8 cubes, 30hz, after displacements using two full length 6'' PSP AeroPorts but I am having trouble calculating displacement.

Anyone ever run a calc for this or have any guidance?

Help will be very much appreciated.

Thanks,

Kevin

I believe he's asking for the volume of displace of the actual port.

r2 x pi x length / 1728 = cf //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That isn't exact displacement. You have to take the integral of the curve and rotate it around the z axis to get the precise displacement.

I have the exact number but I misplace it somewhere. It's been 3 years since I've designed something with it.

the extreme minor .000004579 cf dif will not make a bit of difference tho lolz

Yea, the displacement of the aero as if it were a normal, round port would be close enough because it'd be such a small amount off on airspace if you really wanted to factor in the flared portion

Ok. Thanks everyone. Makes sense now.

You gotta know how to do this if you design boxes.
