摘要： An aerospike engine configured to be connected to a liquid methane tank, and to a liquid oxygen tank is provided. The aerospike engine comprises a centerbody including an aerospike nozzle, an external skirt, and a combustion chamber being defined between the external skirt and the centerbody. The centerbody is additively manufactured from one or more copper alloys and has a plurality of centerbody internal cooling channels. The external skirt is additively manufactured from one or more copper alloys and has a plurality of skirt internal cooling channels. The aerospike engine is configured to supply liquid methane and liquid oxygen through the internal cooling channels to the combustion chamber. Also disclosed are stages of a launch vehicle and a launch vehicle comprising such an aerospike engine, as well as methods for re-entry for a re-usable stage of a launch vehicle comprising an aerospike engine.
