Hirth HM 500
The Hirth HM 500 was a German four-cylinder air-cooled inverted inline engine developed from the Hirth HM 504 in 1938. Although developing the same output of the HM 504 (105 hp) and keeping the same capacity and bore, the HM 500 was a very different engine; the new HM 500 had a one-piece "closed" crankcase for simplified manufacture. The new cooling system reduced cylinder temperatures considerably (15 °C less), and the fuel consumption was also reduced. The HM 500 carried a twin-magneto instead of the two separate magnetos as on the old HM 504. All these changes made that the HM 500 resulted a 12% lighter than the HM 504 and the front surface 37% less than the previous HM 504.Flugmotor Hirth HM 500, Luftfahrt International Nr 6, Dec. 1974 Otherwise the HM 500 continued the typical Hirth use of built-up crankshafts and roller-bearings for crankshaft & connecting rods (Hirth patents) as well as magnesium-alloy crankcases which made Hirth Hirth Engines GmbH is a ...

Hellmuth Hirth
Hellmuth Hirth (; April 24, 1886 – July 1, 1938) was a German engineer who founded the Mahle GmbH and Hirth companies, manufacturing engine components and complete aircraft engines respectively. Biography Hirth was born in Heilbronn, the son of engineer and tool-maker Albert Hirth. He was the elder brother of Wolf Hirth who would go on to become a famous sailplane designer and manufacturer. As a young man, Hirth was sent to the United States to train with the Edison General Electric Company as a mechanic. While abroad, he developed an interest in aircraft, and on his return to Germany in 1909 became involved with the emerging industry. He built his own aircraft in 1910 and soon went to work for the Zeppelin Company building airships. He also became a prominent pilot. Since 1914 he was a Leutnant of the Fliegertruppe, winning the Iron Cross II and being severely wounded. In 1920, he founded his own company to manufacture engine components out of light alloys, and by 1927 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hirth HM 504
The Hirth HM 504 is a four-cylinder air-cooled inverted inline engine. The HM 504 was a popular engine for light aircraft of the 1930s-1940s, and it was used to power a number of Germany's trainer aircraft of World War II. The engine featured a cast magnesium alloy crankcase. The Hitachi Hatsukaze Model 11 was a Japanese licensed version.

Hirth HM 60
The Hirth HM 60 was a four-cylinder inverted air-cooled inline aircraft engine designed in 1923 and first sold in 1924. The engine was of very high quality, and its sales success contributed to Hirth's rapid pre-war expansion. It was a popular engine for light aircraft delivering 80 hp (60 kW) at 2,300 rpm. Later Hirth engines built upon the HM 60's success and provided greater power with many of the same design features.
