This engine is a 9 star cylinders. It was designed to equip medium planes or helicopters. With a power of 1525 cv in H-34, its total cubic capacity is about 29,84 L (and its approximate consumption is 350 L per hour). This powerful engine did not allow however the helicopter to be used with full load by strong heat and in altitude (Algeria), which obliged H-34 to embark only 4 or 5 commandos, instead of the 16 that the cabin can accomodate, when the tanks were full. The number of embarked commandos increased as the tanks were emptied. H-21 used the R1820-103 version of this engine (1425 cv).
