Abstract: A method comprising performing simulations to determine energy transfer between bulk fluid motion of gases through a combustion chamber and resonant acoustic modes of the combustion chamber using a simulation model. The method also comprises configuring one or more combustion chamber parameters for the simulation model to shape the resonant acoustic modes to diminish coupling between the resonant acoustic modes and driving mechanisms at a head portion of the combustion chamber and to enhance coupling between the resonant acoustic modes and damping mechanisms at an aft portion of the combustion chamber. The method further comprises determining whether the combustion chamber meets a predetermined performance level in response to determining that the combustion chamber meets a predetermined combustion stability level.

Abstract: A laminate apparatus for engaging a fluid includes a structural medium made from plies bonded together with a resin. The structural medium defines a fluid facing surface. The laminate apparatus further includes a liner membrane bonded to the fluid facing surface of the structural medium with the resin. The liner membrane has one or more of a desired barrier characteristic and a desired chemical compatibility characteristic with respect to the fluid.
