FIELD: engines and pumps.SUBSTANCE: combustion chamber fire tube comprises circular inner fire tube, circular outer fire tube, at least one resonator, neck and seal ring. Circular outer fire tube has multiple holes for air and surrounds aforesaid inner fire tube to make circular cooling space between inner and outer fire tubes. Resonator is connected to outer fire tube so that resonator vase is separated from outer fire tube to make the clearance relative to outer surface of outer fire tube. Aforementioned neck extends from resonator base through inner and outer fire tubes. Seal ring allows a relative thermal expansion between inner and outer fire tubes nearby the neck.EFFECT: higher reliability.10 cl, 6 dwg |
