Abstract
An apparatus includes a cryo-fuel tank, at least two heat exchangers, at least one valve, and a condenser. The cryo-fuel tank is configured to store cryo-fuel. The at least two heat exchangers are configured to reduce heat of a core flow through an engine, where the at least two heat exchangers have different heat transfer efficiencies. The at least one valve is configured to control the core flow between each of the at least two heat exchangers. The condenser is configured to exchange heat between the cryo-fuel and the core flow processed through the at least two heat exchangers.
Claims20
An apparatus comprising:
- a cryo-fuel tank configured to store cryo-fuel;
- at least two heat exchangers configured to reduce heat of a core flow through an engine, wherein the at least two heat exchangers have different heat transfer efficiencies;
- at least one valve configured to control the core flow between each of the at least two heat exchangers;
- a condenser configured to exchange heat between the cryo-fuel and the core flow processed through the at least two heat exchangers;
- and
- a bypass path configured to route the core flow to avoid the at least two heat exchangers, wherein the bypass path includes an additional heat exchanger with a lower efficiency than the at least two heat exchangers.
An engine comprising:
- a fan configured to generate a core flow;
- at least one compressor configured to compress the core flow;
- at least one turbine configured to extract work from the core flow;
- a cryo-fuel tank configured to store cryo-fuel;
- a first heat exchanger configured to reduce heat of the core flow passing through the at least one turbine;
- a second heat exchanger configured to reduce heat of the core flow passing through the at least one turbine;
- a third heat exchanger configured to reduce heat of the core flow passing through the at least one turbine;
- at least one valve configured to control the core flow between each of the first, second and third heat exchangers, wherein the at least one valve comprises:
- a first valve configured to control the core flow between the first heat exchanger and the second heat exchanger;
- a second valve configured to control the core flow between the second heat exchanger and the third heat exchanger;
- and
- a condenser configured to exchange heat between the cryo-fuel and the core flow processed through the first, second and third heat exchangers.
An apparatus comprising:
- a cryo-fuel tank configured to store cryo-fuel;
- at least three heat exchangers configured to reduce heat of a core flow through an engine, wherein the at least three heat exchangers have different heat transfer efficiencies;
- at least one valve configured to control the core flow between each of the at least three heat exchangers, wherein the at least one valve comprises:
- a first valve configured to control the core flow between a first pair heat exchangers;
- a second valve configured to control the core flow between a second pair of heat exchangers;
- and
- a condenser configured to exchange heat between the cryo-fuel and the core flow processed through the at least three heat exchangers.
