Detonation Engine

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.

AbstractThe experiment system of pulse detonation engine is set up to investigate on influence of diameter on detonation acoustic characteristic. The research of detonation acoustic characteristic of pulse detonation engine for four different diameters in different angles is carried out. Results from the test show that as the PDE diameter increasing, there are increases in amplitudes of impact noise in all angles, and the growth rate of amplitude of impact noise in the 90° direction is generally greater than that in the 0° direction. The smaller PDE diameter is, the distance of most obvious directivity at 0° turning to most obvious directivity at 30° is shorter. When the distance is shorter, such as 200 mm, the duration of detonation acoustic is increasing with the increase of PDE diameter, however, when the distance is longer, such as 3000 mm, it is just the opposite. The maximum duration of detonation acoustic is appeared in 3000 mm under 30 mm PDE diameter which reaches to 1.44 ms.
