Abstract
An engine includes an elongated pulse detonation combustor tube having an arcuate combustion path over a majority of an entire length of the combustor tube, and an elongated portion of the combustor tube being oriented transverse to a central axis of the engine.
Claims10
A combustor for a gas turbine engine, the gas turbine engine having an engine central longitudinal axis, the combustor comprising:
- a cylindrical structure disposed around the engine central longitudinal axis, the cylindrical structure including a cylindrical surface, an upstream cylindrical structure inlet and a downstream cylindrical structure outlet,
- a plurality of combustion tubes circumferentially spaced about the cylindrical structure, each combustion tube of the plurality of combustion tubes being a pulse detonation tube having an upstream tube inlet, a downstream tube outlet, and an elongated arcuate portion extending therebetween that is wrapped around the cylindrical surface, each upstream tube inlet and each downstream tube outlet extending parallel to the engine central longitudinal axis, and each combustion tube of the plurality of combustion tubes being radially exterior to the cylindrical surface from the upstream cylindrical structure inlet to the downstream cylindrical structure outlet.
