Siemens-Schuckert was a German aircraft company that built a number of designs in World War I and inter-war era. They also produced aircraft engines under the Siemens-Halske brand, which evolved into their major product line after the end of World War I. The company reorganized as Brandenburgische Motorenwerke, or simply Bramo, in 1936, and were later purchased in 1939 by BMW to become BMW Motorwerken.

Siemens-Schuckert designed a number of heavy bombers early in WWI, building a run of seven R-series bombers. Intended to be used in the strategic role in long duration flights, the SSW R-series had three engines in the cabin driving two propellers via chains. In the case of engine failure, which was extremely common at the time, the bomber could continue flying on two engines while the third was repaired by the in-flight mechanic. Although interesting in concept, the cost of these and the R-types from other companies was so great that the air force eventually adbandoned the concept until more practical designs arrived later in the war.

They also tried their hand at a fighter design based on the French Nieuport 11 in 1915. Like the Nieuport's Le Rhone, the SSW D.I was to be powered by a rotary engine of about 100 hp. The Germans had copied the Le Rhone as the Oberursel UR.II which was intended to be used on the D.I, but demand was so high that Siemens decided to start producing their own version as the Siemens-Halske Sh.I. The engine took so long to get to production quality that by the time it was ready in 1916 the fighter was no longer competitive.

Instead of simply dropping the work, Siemens-Halske decided to re-work the engine into a much more powerful design, resulting in the 160 hp Sh.III, perhaps one of the most advanced engine designs of the war. When placed in a modified D.I it suddenly became one of best climbing aircraft in the world, and found use in home defense units as an interceptor. Further modifications as the Siemens-Schuckert D.IV improved its handling and performance, becoming what is often considered to be the best fighter of the war. Several modifications of the design were made to produce triplanes and monoplanes, but none saw production. Interceptor redirects here. ...

With the end of the war production of the D.IV continued, mainly for sales to Switzerland who flew them into the late 1920s. With the signing of the Treaty of Versailles all aircraft production in Germany was shut down. Siemens-Schuckert disappeared, but Siemens-Halske continued sales of the Sh.III and continued development of smaller engines for the civilian market. By the mid-1920s their rotary engines were no longer in vouge, but "non-turning" versions of the same basic mechanicals led to a series of 7-cylinder radial engines, the Sh.10 through Sh.14A, delivering up to 150hp in the 14A. The Sh.14A became a best-seller in the trainer market, and over 15,000 of all the versions were eventually built.

Siemens-Halske no longer had any competitive engines for the larger end of the market, and to address this they negotiated a license in 1929 to produce the 9-cylinder Bristol Jupiter IV. Minor changes for the German market led to the Sh.20 and Sh.21. Following the evolution of their smaller Sh.14's, the engine was then bored out to produce the 900 hp design, the Sh.22. In 1933 engine naming was changed by the RLM, and this design became the Sh.322, Siemens engines being given the 300-block of numbers.The Sh.22 design had reliability problems and never became popular. Further development with the addition of fuel injection and a new supercharger led to the Bramo 323 Fafnir, which entered production in 1937. Although rather outdated in terms of design, by this time the engine had matured into a highly reliable powerplant, and 5,500 were produced until the lines shut down in 1944.

In design terms the 323 was basically a dead-end with little growth potential. By the start of the war it's 1,000 hp was already at the low end of the performance scale, and use was limited to transports and bombers. In order to build a 1,500 hp-class engine Bramo started development of a two-row version of the engine as the Bramo 329, mirroring similar developments at BMW who were trying to scale up their Pratt & Whitney Hornet into the two-row BMW 139. Design of both engines was well advanced in 1939 when BMW bought Bramo, and cancelled work on the 329 to concentrate on what would become the excellent BMW 801.

Realizing the two-row development was a risky proposition, Bramo engineers had also started developing axial-flow jet engines in 1938. They were awarded a development contract to continue work on two designs, which would later become the 109-002 and 109-003 when the RLM officially started supporting jet development. The -002 used an advanced contra-rotating compressor for added effeciency, while the -003 used a simpler compressor/stator system that remains in use in modern designs today. The -002 proved to be too complex and work on it soon ended, but the -003 showed definite promise and became the BMW 003. An axial compressor is the name used in the aircraft industry to refer to a particular type of compressor used in jet engines. ...
