PZL M15 Belfegor Designed for big Russian farms, this 1970s Polish agro-jet prototype was powered by an AI-25 jet engine. The engine was the same as used in the Yak-40. It used lots of bleed air to blow the stuff out of the hoppers and in fact is a sound response to a questionable specification. |

The engine was probably envisaged for a big, single engine passenger plane. Three prototype As-5s were built between 1924 and 1927. None were flown. |
