An apparatus for testing candidate rocket nozzle materials includes an elongated member having a combustion chamber extending therethrough, with an inlet at the forward end of the combustion chamber for admitting and igniting a gaseous mixture of hydrogen and oxygen and a nozzle secured to the combustion chamber at the aft end thereof. The nozzle is made of wafers or petals of materials to be tested, with the wafers being secured together at the edges thereof and having a configuration such that the wafers in transverse cross section form a polygon which has an area which increases with distance from the combustion chamber.
