Siemens & Halske Sh 10
The Siemens & Halske Sh 10 is a German aircraft engine that was developed and built by the Berlin- based company Siemens & Halske in the 1920s.
development
The five-cylinder engine was developed in 1925 together with the seven- and nine-cylinder versions Sh 11 and Sh 12 . In this drive series, cylinders with heavily ribbed and attached heads made of light metal were used for the first time to improve the cooling properties . The in-house test runs confirmed better cooling compared to the previous design, which was reflected in the increased intervals between overhauls from 10 to 20 to 50 to 60 hours. The Sh 10 achieved a running time of over 300 hours during testing. The engines then went to the DVL in Berlin-Adlershof in autumn 1926 and passed the type test there, including 150-hour runs under full load . After the approval was granted, the engine went into limited production, which consisted of only 16 pieces. In addition to being used in Germany, these were also exported to Hungary and the USA, where they were used, among other things, to propel the Goodyear airship Puritan .
construction
The Sh 10 is an air-cooled five-cylinder - four stroke - carburetors - radial engine with unit cylinders of steel and low over the liner pulled down, heavily ribbed cylinder heads made of light metal casting. The valve springs are made of rolled flat steel, there is no starter or gearbox.
