Aviatik (Berg) 30.27 & 29

Whereas all previous single-seat fighters designed by von Berg had utilised Austro-Daimler inline engines, the Aviatik 30.27 and the similar 30.29, which appeared early in 1918, were powered by the 160hp Steyr Le Rhone 11-cylinder rotary. Of wooden construction with plywood fuselage skinning, apart from the forward section which was covered by light metal panels, and fabric-covered wings, the Aviatik 30.27 and 30.29 each carried the standard twin-Schwarzlose gun armament, and were initially flown with two-bladed propellers. Subsequently, the original engine cowling (which left the lowest three cylinders exposed) was replaced by a full ring cowling, and the four-bladed Jaray propeller was adopted. Both participated in the July 1918 D-Contest, 30.29 crashing when the upper wing leading-edge collapsed as its pilot initiated a loop.
