Complex system in which a compressor driven by a two-stroke engine blows air into a small cooling turbine to recover the density of the air.

"Eichelberg"

-An intercooler is also taking part in this mission. Finally the air reaches the upper supplementary chamber where a combustion sends the burned gases at speed through the nozzle.

-As the story says, from the cooling turbine comes an effluent air that is added to the main jet. Admission to the compressor occurs at the bottom of the diagram.
