Abstract

motor de detonação em pulso de multitubos sem válvula. é revelado um motor de detonação em pulso de multitubos sem vãlvula incluindo uma pluralidade de tubos de detonação onde cada tubo de detonação compreende uma saída de descarga independente, e a pluralidade de tubos de detonação interconectada a um orificio comum de mistura ar/combustível. no motor revelado, uma mistura ar/combustível é detonada nos tubos de detonação simultaneamente, e o orifício comum de entrada de mistura ar/combustível minimiza comtra pressão causada pela detonação da mistura ar/combustível por direcional múltiplas ondas de choque inversas uma contra outra e usar efetivamente as contrapressões como superfícies de reação recíprocas e efetivamente reduzir o efeito de ondas de choque de retorno em movimentação para montante. os tubos de detonação podem ser não lineares, e podem ter descargas independentes. as descargas independentes podem ser acopladas a um bocal adaptador terminando em uma saída de escape combinada.
