Vapor cooling of detonation engines

摘要

An engine cooling system includes a combustion chamber assembly configured to generate detonation waves and a first vapor cooling assembly. The combustion chamber assembly defines a flowpath between an inner liner and an outer liner. The first vapor cooling assembly includes a vaporization section located adjacent to the flowpath and a condenser section spaced from the flowpath, and is configured to transport thermal energy from the vaporization section to the condenser section through cyclical evaporation and condensation of a working medium sealed within the first vapor cooling assembly.
