ASh21

ASh21 is a Soviet-era aircraft engine. It is a radial engine, meaning its cylinders are arranged in a circle around a central crankshaft. This design was common in early aircraft due to its simplicity and reliability. The ASh21 was developed in the late 1930s and saw service during World War II. It was a relatively powerful engine for its time, often used in trainer aircraft and some light attack planes. Specific performance figures varied depending on the exact variant, but it typically produced around 700-800 horsepower. The engine's robust construction made it capable of operating under harsh conditions. Its production was carried out by various Soviet factories. While not as widely known as some other Soviet aircraft engines, the ASh21 played a role in the development and operation of Soviet aviation during a crucial period. Its design principles contributed to later engine developments in the Soviet Union.
