This Bremen factory is known for aircraft manufacturing in WWII.

-Under the direction of Professor Von O. Pabst ramjets were tested on rotor blade tips of the designs carried out by this factory.

"F-W ramjet"

"Another F-W ramjet version"

-We see two recently published versions.

-Another surprising engine is the turbojet with two single sided centrifugal compressors in chain, to feed the combustion chambers and an even more surprising outlet around the fuselage.

"F-W project"

-It was carried out in 1942 on an FW-190 A-3 changing its name later to FW-190 TL. The engine was called FW-1, and delivered 600 Kgs of thrust.

From Appendix A4/6: The artifact or vertical take-off aircraft with orientating wings driven by ramjets (see main text). We have found information that tells us that the initial rotation, before the ramjets start working, was produced by three small rockets of 300 Kgf of thrust.
