When most people think of an airplane taking off, they picture massive runways that occupy substantial space. While traditional planes need runways to build up speed and generate thrust, vertical take-off and landing (VTOL) aircraft do not.
As the name implies, these aircraft can generate lift without the speed factor. They can take off, hover and land using only vertical space. They're far more space-efficient and usually require less fuel to operate.
The most recognizable VTOL is a helicopter. But fixed-wing aircraft can be VTOL, too.
The Benefits of VTOL
VTOL aircraft provide several advantages that standard planes don't.
First, these aircraft can land almost anywhere. Because the aircraft doesn't need a runway, it offers more flexibility. All they need is a parking lot or an empty building roof!
Modern aircraft capable of VTOL are already in use for hospitals and the military. But experts believe there's untapped potential. Passenger aircraft could bring people closer to city centers and unlock brand-new routes that are more efficient than ever before.
Another benefit is that the aircraft produces fewer emissions. With the spotlight being on climate change, this advantage has many airlines seriously interested in exploring their options.
Newer VTOL concepts use hybrid-electric propulsion systems. Instead of relying solely on jet fuel, the system uses stored energy to go as much as 200 miles with zero emissions! The fuel-powered propulsion system can kick in if the aircraft needs to go longer.
Because the hybrid system combines electric operation with traditional turbines, the CO2 is substantially lower. Existing air corridors could see greener alternatives to conventional planes while new routes could open up to take full advantage of all-electric travel.
VTOL Aircraft and the Future
VTOL technology is nothing new. It's been around for decades. However, revived interest in recent years resulted in the rapid investment and development of new aircraft.
Many aviation experts say that commercial and private air travel will benefit from VTOL very soon. It's ready to transform aviation, providing a greener and more efficient mode of transportation.
