Ramjet

These images are our preliminary tests on Ramjets.  The Ramjet itself is made almost completely out of stainless steel.  In the first test we used propane as fuel and a fairly high powered leaf blower for air flow.  The propane completely combusted and the ramjet put out pretty decent power. Here is a sound file of the ramjet combusting with propane  In the second test we used high pressure injected kerosene which did not completely combust due to a lack of air flow through the ramjet.
