The Americans as well as the British and the Russians have been proposing engines for high speeds and altitudes.

“Hydrogen fuel supply”

-The proposals made by a certain R.S. Rex were three variants of compound engines between turbine, fan, ramjet and rocket, using liquid hydrogen.

-A hydrogen converter is used to pass it to the pre-combustion chamber to drive the fans and to feed the main afterburners. The third turbine is to run the system itself.

“Motor Rex 1”

“Rex 2 engine proposal”

“Rex 3 engine proposal”

From Appendix 6: We extend the information of the main text with a new explanation of the Rex engine in its three versions, I, II and III.

-The Rex I is schematically represented as follows and published in the year 1954.

“Rex I combustion system”

-It runs on gasified liquid Hydrogen and Oxygen passing through the heat exchangers and passing through three staggered and successive combustion chambers.

“Real appearance of the Rex I engine”

-After the third combustion, the exhaust is taken to the heat exchangers to heat and gasify the fuel and the comburent.
