Startup Bartini has unveiled its eVTOL concept in July and says it is working on two variants — a 2-seater and 4-seater — with the intention of an air taxi service. The company is named for the Italian-Soviet aircraft designer Robert Bartini who discovered the “Bartini Effect” — which is the increase in thrust created by mounting co-axial counter-rotating thrusters within a nacelle. The company has built a 50% prototype to prove that rotating ducted thrusters, in conjunction with the aircraft’s aerodynamic shaping, would reduce power consumption in cruise; the model is expected to fly in 2017.

Bartini plans to launch the aircraft with a demonstration flight with the 2-seat version in the third quarter of 2018, followed by a possible 4-seater in 2020. The company is considering hydrogen fuel-cells for the future, which would give it a 4x range increase.

According to the Bartini White Paper: “Technology and configuration (coaxial variable pitch propellers in a quad copter convertiplane with aerodynamics of the carrying wing, patented) decrease power consumption up to seven times and ensure long-distance flights at altitudes comparable to small helicopters or airplanes. Expected market price may stay within $100k due to absence of complex components, wings, ailerons, chassis, moving airframe parts, as well as simple assembly processes. High degree of body-shape variability within the aerodynamic solution, no need for takeoff/landing infrastructure, safety due to 8 motors and coaxial propellers in 4 engine groups and human-factor reduction, noise-levels within urban regulation.”

The company, founded in 2015 Bartini, is based in the Skolkovo Technopark, on the western outskirts of Moscow. The initial funding has come by the company’s eight founders; it is part of the Blockchain.aero consortium.

The Blockchain consortium is the first crypto-currency platform for mass urban aviation, whose task is to automate the charging, maintenance and parking of flying cars: “Blockchain.aero is a blockchain for mass urban aviation market and a platform to tokenize aerial vehicles and infrastructure. We are a decentralized business consortium that aims to deploy urban community-driven aviation systems for passengers and city managers in 2020. First test flights are aimed for Dubai, Singapore or Sydney in 2018.” Flight scheduling will be done via a mobile application and will offer different levels of service from fast to entertainment flight.
