Abstract
A propulsion system includes a first compressor in fluid communication with a fluid source. A first conduit is coupled to the first compressor, and a heat exchanger is in fluid communication with the first compressor via the first conduit. A second conduit is positioned proximal to the heat exchanger. A combustor is in fluid communication with the heat exchanger via the second conduit and is configured to generate a high-temperature gas stream. A third conduit is coupled to the combustor, and a first thrust augmentation device is in fluid communication with the combustor via the third conduit. The heat exchanger is positioned within the gas stream generated by the combustor.
Claims16
A propulsion system, comprising:
- a first compressor in fluid communication with a fluid source;
- a first conduit coupled to the first compressor;
- a heat exchanger in fluid communication with the first compressor via the first conduit;
- a second conduit positioned proximal to the heat exchanger;
- a combustor in fluid communication with the heat exchanger via the second conduit and configured to generate a high-temperature gas stream;
- a third conduit coupled to the combustor;
- and
- a first thrust augmentation device in fluid communication with the combustor via the third conduit, the heat exchanger being positioned within the gas stream generated by the combustor.
A combustor, comprising:
- a first toroidal casing circumscribing an axis and having an inlet configured to receive fluid, the first casing defining a first internal chamber in fluid communication with the inlet;
- a second toroidal casing disposed within the first internal chamber and circumscribing the axis, the second casing having an outer wall defining a second internal chamber, the outer wall having a plurality of orifices formed therethrough, the orifices providing fluid communication between the first and second chambers;
- a plurality of fuel injectors positioned to inject fuel into the second chamber through the orifices;
- and
- outlet structure defining at least one channel in fluid communication with the second chamber, the at least one channel being oriented parallel to the axis.
