Motor Porn

1918 Clerget Engine, 130 hp, 1 200 rpm, 170 kgs 


  1. Radial engines needed to be warmed up - for much longer than we today appreciate, before they were given full power. It took a while to get the oil moving and hot. In-line liquid cooled engines such as the Rolls-Merlin, which became the gold standard didn't suffer from that problem, but they were more prone to failure from battle damage if they were hit in the coolant lines. It's like Mick Jagger said, "You can't always get what you want."

  2. I saw one of these in a local museum. It's a rotary engine as opposed to a radial. The crank is fastened to the airframe and the propeller is attached to the engine itself. The engine and prop turn as one unit. As LL points out, lots of pros and cons. Video at the link:
