Kirkham B-6, In-line 6 Engine

During 1909 and 1910 Charles B. Kirkham made several successful aircraft engines based on his automobile motors. In 1911 he began to manufacture the above engine – his first designed especially for airplane use. It featured concentric valves, primarily to assist exhaust cooling. Kirkham claimed that this engine was “outstanding in light weight, low head resistance, and freedom from vibration.”

It powered the Aerial Exhibition Company’s biplane design, the Burgess Hydroplane Model F, the Kirkham tractor biplane design, and the Thomas Model TA.
