Mercedes 180hp DIIIa Engine Reproduction


Exact Reproduction

The D.III is an inline 6 cylinder of 15000cc, has a 140mm bore and a 160mm stroke. It produces 180HP @ 1400RPM and it was a favourite of many of the aircraft designers in Germany during the First World War. These engines were favoured because they are very reliable in operation and powerful, the exhaust note tells you it means business! The Vintage Aviator is dedicated to building exact reproductions of First War World aircraft, using either original plans or reverse engineering surviving musuem examples. Installing the original powerplants is a vital part of these projects – but sourcing the engines is often much more difficult than the airframe construction plans. Over the last few years, we have undertook the building of exact reproduction engines. This allows us to build aircraft that would otherwise be impossible to put back into the air under their own, historically correct, power. Our BE.2’s, RE.8’s, Fokker D.VIII’s and Sopwith Snipes have all been powered by TVAL new built engines. The existence of those engines also opens the door to the possibility of building other aircraft types using the same powerplants. With so many German aircraft using the Mercedes, exciting potential projects based on those aircraft have been put on the back burner while engines were sought. Over the years, we have managed to obtain only 2 original 180hp Mercedes engines. Many exist in museums, and a few are rightly prized by private collectors. There are just not enough “in circulation” to allow us to realisically pursue many of the German aircraft projects we’d love to tackle. Several years ago, encouraged by the success we had building relatively “simple” engines such as the RAF 1A or Oberusal, we decided to commence what became a very long project to reproduce the 180HP Mercedes. From the onset it was obvious that creating a new build Mercedes 180HP engine was not going to be an easy task. Only a handful of these engines have survived despite
