REFLECTOR: wheel pants

[Jim Agnew]

I have a rear facing Small scoop on top of the back of the wheel pant.  It serves two purposes, one to create a vacuum to help the forward nacca scoop bring in air and second and most important to cause convection to vent the heat build-up in the wheel pants when you stop.  The pants turn into an oven when you stop with little to vent them.

Thx Dave, I've got NACA vents on the forward inside of the pants, good point that the more holes, the better for brake cooling. However, I was asking more from a cruise efficiency standpoint. With the NACA inlet coupled with normal air entry by the wheels does it make sense to have an outlet at the rear of the fairings to move that air so as not to build up a draggy high pressure area in the pants??  Tom


Tom after  flying a number of canard planes with wheel pants believe me you want all the vents you can get in the pants.  One time I didn't put the vent holes in the top of the pants and after I taxied for a good mile after landing I learned never to do that again.  After parking the heat built up so bad in the pants that after going into a building to check on getting gas, I came out and found that the end of the gear had bent up till the brake disc came in contact with the strut and I was grounded in the middle of Windover UT with a broken foot and no place to get it fixed.  So when it comes to pants you can put enough vents in them.  I recommend that you put them in the side and out the top as well as a little out the back.  You can make some real nice small NACA scoops, going fwd and aft direction, to do the job and looks cool as well. They only have to be around a inch across to work.
