Recognition (WEFT)
| W — Wings | High-mounted, rotary |
|---|---|
| E — Engines | 1 × piston, fuselage-mounted |
| F — Fuselage | 13.91 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Single main rotor of 14.5 m with a conventional anti-torque tail rotor
- Long greenhouse-style canopy over the pilot and crewman
- Single Ivchenko AI-26GRFL radial piston engine
It had a conventional main and anti-torque rotor layout driven by an Ivchenko AI-26GRFL radial piston engine, and bore a striking resemblance to the Sikorsky H-5. The pilot and crewman sat under a long greenhouse-style canopy.

History
Initially designated Yak-22, the Yak-100 was developed in direct competition with Mikhail Mil's Mi-1 and first flew in November 1948. Manufacturer's trials were completed in June 1950, with successful State acceptance trials following later that year.
Variants
Two prototypes were built. The second prototype had a third seat as well as other minor improvements.
Where you'll see it
Although successful in trials, the Yak-100 was not put into production, because the Mi-1 had already been prepared for production before the Yak-100 had completed acceptance trials.
