Pogo Accumulator Optimization Based on Multiphysics of Liquid Rockets and Neural Networks

What is it about?

Pogo instability in liquid propulsion rockets is analyzed numerically, and a pogo accumulator is installed to mitigate the effect. In order to optimize the pogo accumulator for optimal performance, multi-physics of liquid propulsion rockets and artificial neural networks are applied. The optimization process finds the lowest-resonance expected design for the pogo accumulator.
