A Study of the Engines Exhibited at Olympia the Aero Show

A STUDY of the engines at the Olympia Show leads one to the general opinion that American practice has exerted a profound influence on foreign airplane engine designs. What we are pleased to call the “American” type of aircooled cylinder is now almost universally adopted, the last to come into line being the well known Bristol firm, which up to that time had consistently used an all-steel cylinder.
