A New Light Aeroplane Engine: The 60‐h.p. Four‐Cylinder Inverted Air‐Cooled Hirth with Coil‐Ignition Described

Abstract

FOR many years, Helmut Hirth, the well‐known pre‐war pilot and engine‐constructor, has been working on the construction and design of a new cheap engine for touring aeroplanes. Those who know his early engines expected to see a high revolution, water‐cooled, two‐cycle engine with double pistons, something after the type of the motor‐cycle engines which have run successfully in many races. It was a great surprise, therefore, when he came out about a year ago with an air‐cooled, four‐cylinder, four‐cycle, vertical engine.
