I will be adding my technical publications and more pictures of rockets I have developed and tested. Right now, I only have these pictures of my Liquid Oxygen (LOx) and Tri-ethyl-aluminum (TEA) rocket! This is the first rocket I tested that was all my own design.

Here you can see the LOx manifold with the off-center hole which is the oxygen inlet and the TEA injector with the copper ring around the flange. It looks kind of frosty in the center. Actually that IS frost. The assembly is still cold from the last test, because we purge with LOx after shutting off the TEA. I made the TEA injector as a face shut-off check valve with a conical pintle. The TEA cone intersects a cone of LOx. Eleven LOx injection holes impinge on a conical splashplate--you can just see those eleven holes around the TEA injector. You can see "shadows" of those holes in the LOx manifold, little spots where there is less frost. That's where some TEA vapors must have put a little residue on the metal surface. Here is the assembly in the test rig, ready for hot fire.
