The Mil Mi-34 (NATO reporting name: Hermit) is a light helicopter designed by the Mil Moscow Helicopter Plant in either a two or four seat configuration for utility and training. It was first flown on 17 November 1986 and introduced at the Paris Air Show in 1987. The Mi-34 entered production in 1993, and is capable of performing aerobatic manoeuvres, including rolls and loops.

A new domestic engine version, Mil Mi-34M1 made its first hovering flight in October 2024. It uses the Russian made VK-650V turboshaft engine instead of the previous Radial engine.[1]

Notes

[edit]
  1. ^ Jane's (2004–05) indicates that the Mi-34S is the base design and that prior to 1999, all marketing literature referred to the Mi-34 using the Mi-34C designation. The S or C suffixes were used to indicate the aircraft's certification by the Interstate Aviation Committee. The Russian word for certified (Russian: Сертифицированные) begins with the Cyrillic C, which is romanized as the letter S.
