Exhaust Plugs for Aircrafts in San Diego

I haven't had the time to post on my blog about Aircraft exhaust plugs in quite some time now. I may retire this blog and move to my own domain where I can host a larger site with more details about Aircraft Exhaust Plugs.

Aircraft Exhaust Plugs improved aircraft muffler and the method of making it is disclosed. It is a plug muffler design having an outer housing and an internal exhaust conduit. The exhaust conduit has a center partition that blocks the flow of exhaust gas through the conduit. A number of holes are formed through the conduit wall such that the exhaust gas passes out through the holes on the inlet side of the partition and reenter the conduit on the outlet side of the partition. Unlike previous designs, the holes formed in the exhaust tube of the muffler are not flat and do not have hoods. Rather they have formed surfaces that slope. The formed surfaces both protrude above and below the exhaust tube wall. Thus the formed surface creates a directional flow path for the airflow to help increase the velocity, which consequently helps to move exhaust gases through the baffle as opposed to straight holes. The indented holes serve another purpose. Those surrounding the center plug act to wedge the plug in place by forming a circumferential, integral bead lock around the partition plate, which secures it in a fixed, stationary position. This, coupled with a series of welds placed around the tube, keeps the plug from falling over or becoming loose within the exhaust tube.
