Aeroacoustics of Aft-Finocyl Solid Rocket Motors

The present paper aims to investigate the intimate effect of the propellant grain geometry on Pressure Oscillations (PO) onset and characteristics in aft-finocyl Solid Rocket Motors (SRMs). With this purpose, P80 SRM, first stage of VEGA launcher, and a mock-up version of POD-Y scaled at the size of P80 SRM, named Big POD-Y, are assumed as test cases. The numerical simulations are performed by exploiting the Q1D approach of AGAR (Aerodinamically Generated Acoustic Resonance) model, based on the assumption that aeroacoustic lock-in represents one of the main driving mechanisms for PO onset.
