Sam Dalziel Heron was born on May 18, 1891, in Newcastle upon Tyne, England.
He attended Alleyn"s School in Dulwich, the Goldsmith College (London University) and Durham University in Newcastle upon Tyne.
Samuel Dalziel Heron (South Dakota Heron) (18 May 1893 to 10 July 1965) was a British born aerospace engineer who made major contributions to the design of piston engines. While working in Britain he carried out the first systematic research into air-cooled cylinders. In the United States.A he contributed to the design of the Curtiss R1454, invented the sodium cooled poppet valve and became technical director for aeronautical research for the During the First World War, Heron worked at the Royal Aircraft Factory.
From 1915 to 1916 he worked with Professor Ampere-hour Gibson on the first systematic research into the design of air-cooled engine cylinders.
They concluded that (1) aluminium should be used for efficient conduction (2) the cylinder head should be in one piece because conduction through metal-to-metal interfaces could not be guaranteed (3) the cylinder head should provide the shortest escape path for heat at the hottest parts across the greatest cross section. Working with Major F.M Green, they developed the Royal Air Force.8.
This was a 14 cylinder 300 hp radial engine, which first ran in September 1916. On the breakup of the Royal Aircraft Factory in 1917 he joined Siddeley-Deasy.
He disagreed with Juris Doctor Siddeley over the redesign of the Siddeley-Deasy Puma cylinder head and other design policies.
As a result, he resigned and left for the United States.A in 1921. 19230807 Great Britain 19230020147 19230807, Sam Dalziel Heron, "Improvements in the cooling of valves or other moving parts of internal combustion engines that are subject to high temperature", published 1924-1911-07, issued 1923-1908-07.
