Founded on December 1, 1918 by N. E. Zhukovsky, the Central Aerohydrodynamic Institute is the first aircraft design bureau in Russia. Central AeroHydrodynamic Institute is also referred to has TsAGI (Defined: Zhukovsky Central AeroHydrodynamic Institute). The institute's headquarters is currently in Zhukovsky, Russia and according to the institute, is the largest scientific research center in the world. The institute researches, tests and designs all types of aircraft from helicopters to jets and spacecraft. The institute has recently been researching, designing and testing electric vertical takeoff and landing (eVTOL) aircraft for Urban Air Mobility (UAM).

The small ERA concept design (and possibly a subscale prototype) eVTOL aircraft holds one passenger, uses four ducted propellers, four electric motors, powered by batteries, has one low wing and uses fixed skid landing gear. As of 2021, the researches have completed their three year study of ERA eVTOL aircraft and used the institute's T-102 subsonic wing tunnel for some of the research.

Central Aerohydrodynamic Institute foresees that eVTOL will greatly help with intra-city (within the same city) and inter-city (between two cities) for air passenger transportation, emergency medical evacuation, air cargo and more. The institute has stated the next stage of work will be to create a working technology demonstrator.
