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.
