Turbojet engine patented in 1941 by André Brunet.

-The mechanical skills are noticed but we see that the compressor has a constant section without real compression. It acts as a multiple fan.

"Semi section of André's engine"

-Neither the combustion chambers seem sufficient and with a very advanced spark plug.

-It uses ball bearings at all points, which does not allow expansion. The mentioned bearings are embedded in lace and nuts that are topping both ends.

-Perhaps the merit was that it occurred in March 1941.
