A power generation technique utilizing a pulse detonation engine to drive a piston connected to a linear power generator is described. Coupled magnetic–electric–mechanical models for the mass–spring–damper system are developed. The system is characterized by nonlinear damping due to the rare earth permanent magnets used in the architecture of the generator and a piecewise continuous external forcing function from the pulsed detonation. An analytical model is built to simulate the system, calculate the electromagnetic forces and estimate the power output. The analytical model used in this concept is suitable for flat type linear generators.
