Union Engine Cylinder
Designed in 1915, the 89 kw (120 shp) Union aircraft engine was the first to pass the U.S. government 50-hour test, which took place in 1917. Union engines were built primarily for use in lighter-than-air craft. A Union engine of this type powered the trans-Atlantic trial and record flight of the U.S.N. Airship C-5 in 1919.
