ABSTRACT:
A pulsating combustion system comprising a pair of pulsating combustors of the same structure connected in parallel between an air-intake chamber and an exhaust chamber and having an air-intake pipe and an aerodynamic valve fitted within the air-intake pipe. A separation valve is located in said air-intake chamber, for partitioning the air-intake chamber into a sub-chamber communicating with the air-intake pipe of the first pulsating combustor and a sub-chamber communicating with the air-intake pipe of the second pulsating combustor. In operation, the separation valve partitions the air-intake chamber into two sub-chambers, and the pulsating combustors are operated independently of each other for some time. When the pulsating combustion performed by either pulsating combustor becomes sufficiently stable, the separation valve is gradually opened, thus connecting said pulsating combustors. Thereafter, both combustors continue to perform stable pulsating combustions, perfectly out of phase.
