Sometimes, the name is written as Göbel-Goe. It was the "Gandenbergersche Maschinenfabrik" by Georg Goebel, in Darmstadt, Germany.

-They built rotary engines during the First World War. These engines were copies of the French Gnome.

“Goebel Goe, 7-cylinder”

In addition to the Goebel-Goe Type II, with 7 cylinders giving 110 CV, there were others with 7 cylinders, such as Type V giving 65 CV and Type VI with 40 CV.

-In terms of size, for example, the Go-V measured 700 mm in diameter and the Go-II, 980 mm.

-The Go-III (Type III) had 9 cylinders and its diameter was already 1,140 mm.

-On October 30, 1917 there appeared a variant of the Fokker Dr.1, in an attempt to increase its performance, powered by a 160/170 CV version of the Goebel Goe III engine. Other versions gave 178 CV.

“Goebel Goe Go-III”

-At the Luftwaffe Museum the Go-III 9-cylinder is exposed. In the main text it appears without the cover and front propeller hub.

“Goebel-Goe Go-III” (PiP)

-In this Museum there is the peculiarity of exposing the engines hanging from cables.

-We show an 11-cylinder derived from the III giving 180 CV on the Dreindecker type 4 in the year 1918.

-The IIIa gave 170 CV and there was a 200 CV Goebel Goe installed on the Kondor E3a.

-The Polytechnic in Torino possess a Goebel Goe Type III 11-cylinder, included in its fabulous collection that includes from before WWI to WWII.

-It's the Capetti Collection.

“Goebel Goe, Type III”

-All the engines at the Polito have some strips in their upper front part to place a plate with written data relative to that particular engine. They are clearly visible in this photograph.

-In a recent found German book from the Goebel-Goe III time, it is called Goebel-Goero III.

-It remains here with the possibility of knowing it with this name as well.

-A Goebel-Goe with two opposed cylinders giving 20/25 CV appears in the Nasm archives with Fot. (BG-400300-20).

From Appendix 12: We found a drawing of a rotary engine that is not usual for its rear appendix.

"We located this drawing in a German WWI magazine"

-Maybe it's a project or an adaptation.
