Acoustic dissipation studies were carried out to determine effect of purely geometric variables on acoustic performance leading to axial mode combustion instability; by using interchangeable parts, it was possible to vary nozzle throat diameter and to simulate geometry of cylindrical-bore grain at various motor burn times; model was acoustically driven by pulse decay, steady-state decay, and steady-state resonance; methods are compared, and applicability of each is discussed; steady-state-resonance method is suitable and promising.
