Genealogy of the AEG C VII and C VIII, as far as I know (and with German aircraft of WW1 one never knows…)
AEG C VII – a 1917 C-type “light” (forerunner of the later CL-category). Number built: 3.
Variants:
- Basic variant: straight wings, Daimler D III
- C VII/2: heavily swept-back wings
- C VII/3: still stronger swept-back wings and minimum gap
AEG C VIII – a more aerodynamic development of the C VII. Number built: 1 or 3
Variants:
- Biplane: I struts, Daimler D III. Number built: 2 (Herris, AEG Aircraft of WW1) or just a prototype (Lange, Typenhandbuch)
- Triplane variant. Herris states that it was the third prototype, while Lange says that it was the rebuilt biplane prototype.
Smaller triplane
Herris in AEG Aircraft of WW1 (p. 46): “AEG had proposed a smaller, lighter triplane in November [1917] but the disappointing flight-test results of the C VIII triplane eliminated that idea as well”.
I have no more information, but it seems to me it was rather an idea than a real project.
Any further information or corrections are more than welcome!
