Intelligent transport technology is taking over the world step-by-step. And one of them fueling the growth is eVTOL (electric vertical takeoff and landing). This particular market is growing significantly, thanks to the rising awareness towards traffic congestion, low maintenance costs, and rapid technological advancements. It is estimated by MRFR that the eVTOL aircraft market could reach $4,063 million by 2030 with North America and Europe dominating the segment.
What is eVTOL and UAM?
eVTOL aircraft is the next-generation autonomous electric aircraft offering enhanced safety and comfort and minimised noise. These vehicles provide flexibility, convenience, fast commute and reduced air pollution. Undoubtedly, these eVTOL aircrafts are opening up air travel to all in new ways.
From an environmental perspective, eVTOL saves fuel and time as compared to normal aircraft that circle busy airports waiting for runaway space. Safety is another aspect as it is estimated that 85% of aeroplane accidents occur during takeoff and landing. Eventually, a multitude of companies are in pursuit of bringing about realistic air taxi services in this category. These projects eVTOL the future of unmanned air mobility (UAM).
A British eVTOL developer Samad Aerospace recently shared its plans for its two-seat, hybrid electric personal VTOL aircraft dubbed Q-Starling. As per the company, the Q-Starling has a length of 26 feet and a takeoff weight of 1040 kgs. This eVTOL has a range of 500 miles and can cruise at 250 knots (km per hour) at an anticipated service ceiling of 15,000 feet.
The fly-by-wire aircraft features a side-stick controller through which the pilot can command all three axes of rotation along with vertical and forward movement.
However, Samad Aerospace is not the only one that works in making eVTOL the future of UAM. Here are a variety of eVTOL concepts under development across the world and supported bynotable aerospace companies.

The company announced that they have created more than 1,000 test flights. It can carry 2 passengers and can hold a maximum weight of about 150 kg. Stephen Wolf and Alexander Zosel established Volocopter in 2011 in Karlsruhe (Germany). They manufacture aircraft, provide air taxi service, and permit passengers to book flights through the app.
Aurora was developed to serve as an air taxi in urban environments and also to fly, to and from the Skyports of Uber. The PAV or Passenger Air Vehicle is a four-passenger eVTOL aircraft. It functions on batteries and electricity. It can cover 56 mph at the cruise speed of 90 km/h. The aircraft comes with eight propellers, three surface wing configurations, and one tail-mounted pusher propeller. Aurora expects that the takeoff noise will blend with the background road traffic sound and be inaudible while in cruise flight. The company has revealed three design models, which have been considered. Aurora Flight Sciences was established by John Langford in May 1989.
Workhorse launched its first electric helicopter on April 30, 2018 in Cincinnati, Ohio. It is said to be the first manned flight in the world under the hybrid-electric VTOL aircraft category.
