    Flying Cars could be the Next Big Thing

    While the idea of hovering motor vehicles might once have been considered farfetched, it’s certainly not the case today. Companies around the world are reaching new heights to develop flying cars that could one day be flown by commuters to work or even over longer distances for leisure travel.

    UNSW aerospace design expert, Dr. Sonya Brown from the School of Mechanical and Manufacturing Engineering, says the aim of these vehicles is to eventually provide another means of urban air mobility to help reduce congestion on the road.

    “Long-term, flying cars will offer us another means for short and personalized travel,” she says.

    “We’re starting to see an emergence of flying car variants in development around the world, and even here in Australia, as more companies are investing in these vehicles.

    “Some early adopters of this technology include rideshare companies and emergency services, given some vehicles are being designed to be more versatile than traditional aircraft and helicopters.”

    What exactly are they?

    Flying cars resemble a cross between a drone and a small aircraft, so most will have wings and typically include between four to eight rotors.

    They can fly a few hundred to a few thousand meters above the ground, occupying the air space above where you’d expect to see drones flying but below standard flying commercial aircrafts.

    While it probably won’t get someone from Sydney to Melbourne on one battery charge, flying cars could potentially travel up to 250 kilometers in one ride.

    “The underlying technology that’s so important with flying cars is the ability to both take off and land vertically and fly horizontally as well. This makes the mechanics much more complex than a helicopter which primarily has vertical propulsion,” says Dr. Brown.

    “And that’s why we’re calling them flying cars because they resemble the type of travel we would do with cars.”

    A win for the environment

    Prototypes of flying cars are currently being designed with electrically powered rotors meaning they can be battery operated. As long as the batteries are recharged in a sustainable manner, for example using wind or solar energy, the flying cars won’t emit any harmful emissions into the environment.

    “Ideally, the aim is to design these green vehicles so that they reduce emissions whilst reducing traffic congestion on the ground as well,” says Dr. Brown.

    “With growing research in the renewable energy sector, I think there’s huge potential to consider other alternative energy sources, such as hydrogen, to power the flying cars in the future.”

    Keeping the hand brake up for now

    Slow down—flying cars won’t take off just yet. There are a few bumps to get over first.

    Some of the challenges the industry is looking to solve are around regulation and traffic control. Similar to commercial flights, flying cars will need traffic control rules, corridors and flight paths to establish right of way to avoid any potential collisions.

    “There’s a lot of work going into developing collision avoidance systems, particularly focusing on how these vehicles are going to communicate with each other to make real-time decisions on things such as right of way,” says Dr. Brown.

    “There’s also an appetite from industry to make them pilotless or remotely piloted.”

    She says even though future flying car models could be autonomous, users may need much more experience than a simple driver’s license to get behind the wheel of one.

    “If we take a closer look at some of the flying cars in development, they are flown by highly trained and qualified pilots. But if we want to make them more accessible, then we need to bring the licensing requirements down,” says Dr. Brown.

    “It will be up to regulators and managing Government bodies around the world to work out what licensing category it fits into it—because currently there isn’t one.”

    Flying cars also bring technical challenges such as battery life, particularly how many times it can be recharged before the battery duration starts to decline. Also, many of these vehicles can have up to eight rotors—which can be very noisy.

    “More acoustic studies need to be done to try to minimize the noise of the propeller inside these rotors,” says Dr. Brown.

    “In the future, if there are going to be hundreds or even thousands of these occupying the skies above highly populated areas, it’s important that we consider the impact the noise will have for people in their homes below.”
