Yakovlev Yak-18PM

The Yak-18PM is a modified version of the original Yak-18 aircraft designed specifically for competitive aerobatic displays within the Soviet Union. Its construction was tailored to meet the demanding maneuvers required by high-level international competitions. It proved highly successful, winning multiple world championships in the 1960s and 1970s.

The most significant modification was the introduction of retractable landing gear to reduce drag and improve the aircraft's power-to-weight ratio. It also featured a more robust construction to withstand the extreme G-forces of aerobatic flight. The wings were altered to improve roll rate and agility.

The Yak-18PM was introduced in the mid-1960s, specifically around 1966, to update the Soviet national aerobatic team's equipment. It quickly replaced the older Yak-18A models in competitive circles. It remained a dominant force in world aerobatics throughout the 1970s.

The aircraft is powered by a single Ivchenko AI-14R radial piston engine. This engine provided the necessary thrust to pull the aircraft through complex, vertical aerobatic maneuvers. The reliability of this engine was crucial for the demanding routines performed by Soviet pilots.
