The Antipode supersonic private jet would fly between New York and London in just 11 minutes.
Talk about hopping the pond.
A proposed hypersonic jet would fly passengers from New York to London in just 11 minutes, and from New York to Sydney in about half an hour, by breaking the sound barrier.
The Antipode luxury business airplane concept dreamed up by Canadian industrial designer Charles Bombardier would reach Mach 24 – or 24 times the speed of sound – to zoom up to 16,000 miles per hour.
That’s 12 times faster than the Concorde, the groundbreaking supersonic jet that flew from New York to London in less than three and a half hours, and just one Mach number below a space shuttle’s re-entry speed into the Earth’s atmosphere.
The design conceived with Lunatic Koncepts founder and designer Abhishek Roy resembles a bird with a short body, pointed beak and long, angled wings to glide and land on a 6,000-foot runway.
Bombardier created shockwaves earlier this month in proposing a supersonic craft called the Skreemr that would travel at Mach 10 and touch down in London just 30 minutes after leaving NYC.
But he decided to double down for an even speedier design.
“I wanted to create an aircraft concept capable of reaching its antipode — or diametrical opposite — as fast as possible,” Bombardier told Forbes.
He teamed up with Joseph Hazeltine of Wyle Inc. to solve some technical problems such as the sonic boom noise this jet would create over land, and the massive amount of heat that would build up on its nose and wings from reaching such blistering speeds.
He explains on his website that the even more streamlined design incorporates reusable rocket boosters attached to the wings to take off directly from any airfield, climbing up to 40,000 feet to reach Mach 5.
Then acceleration boosters separate from the Antipode and fly back to the airbase, while the jet’s onboard computer ignites the supersonic combustion ramjet engine to accelerate up to Mach 24.
The Antipode would reduce the heat and sonic boom noise by channeling some of the air through a nozzle on the nose of the aircraft, which would induce a phenomenon called “long distance penetration mode” that would drop its surface temperature. The leading edge of the wings would also be fitted with linear nozzles so air could flow over them and cool, as well.
The jet would also be outfitted with emergency compact rocket boosters that could be ignited to slow down the aircraft.
Bombardier envisions the elite jet being used “during time-sensitive crises” to “transport highly ranked officials across the globe in a matter of hours.”
It’ll be some time before this dream becomes a reality, however. The stable and reliable supersonic scramjet engine required to reach Mach 24 hasn’t even been mastered by NASA yet.
There’s also the tricky question of how passengers would tolerate the paralyzing g-forces that they would experience onboard the aircraft at Mach speeds.
As for the pricetag, Bombardier would only tell Forbes that “it would still cost a lot more than any business jet on the market today.”
