The Mil V-7 was an experimental four-seat helicopter built to test a jet-driven main rotor, in which engines at the blade tips turn the rotor directly so that no mechanical transmission or tail rotor torque compensation is needed. Mikhail Mil meant it as a small proof-of-concept step before an ultra-heavy-lift helicopter with a main rotor nearly 60 metres across, and a government directive of 20 December 1956 called for its development. It was the smallest and lightest of the Mil bureau designs, with a teardrop-shaped all-metal fuselage, rectangular wooden-ribbed blades fed with fuel through the rotor shaft, and a cabin for the pilot and three passengers or a stretcher patient and attendant. Plant No. 329 began a trials batch of five machines in 1957, four aircraft were built, and only one is known to have flown.
