Boom Supersonic unveils updated “Overture” supersonic airliner design

Set to begin production in 2024, the aviation company Boom Supersonic has unveiled updates to highly anticipated ultra fast “Overture” at the Farnborough International Airshow on July 19.

After almost seven years in development, the supersonic airliner, which is expected to go from Seattle to Tokyo in less than 5 hours, is now one step closer to reality.

Already designed to cross the speed of sound, Boom has now decreased the Overture’s passenger capacity, increased its number of engines and reconfigured the fuselage and gull wings in order to create a more efficient and “quiet” aircraft.

The aircraft is now designed for manufacturability and for maintenance. The tail-mounted engine in the old design would have been difficult to reach and maintain. Everything we’ve been saying for the last few years about fuel efficiency about the airplanes remains true

According to BOOM, the aircraft will now feature four smaller wing mounted engines, which will decrease the operational costs and allow it to fly quieter. Additionally, these engines will enable the Overture to soar at Mach 1.7 or about 1,300 miles per hour over water-faster than the speed of sound.

Key features:

Four-engine design: Overture will be powered by four powerful, wing-mounted engines that enable the airliner to cruise at Mach 1.7 over water and just under Mach 1 over land. Additionally, the four-engine design reduces noise while also decreasing costs for airline operators.

Quieter operation:  On take-off, Overture will use the world’s first automated noise reduction system. The airliner will fly without afterburners, meeting the same strict regulatory noise levels as the latest subsonic airplanes.

Contoured fuselage: Boom has applied the “principle of area-ruling” design technique to minimize drag and maximize fuel efficiency at supersonic speeds. Therefore, the Overture’s fuselage now has a larger diameter toward the front of the aircraft and a smaller diameter toward the rear.

Net zero carbon: Sustainability is woven into all aspects of Overture, from design and production to flight and end-of-life recycling.

Most of the Overture will be built using carbon fiber composites hence the aircraft will be lighter and therefore more fuel efficient.

Aviation has not seen a giant leap in decades. Overture is revolutionary in its design, and it will fundamentally change how we think about distance. With more than 600 routes across the globe, Overture will make the world dramatically more accessible for tens of millions of passengers

Boom Supersonic also announced a landmark partnering agreement with Northrop Grumman to develop special mission variants for the U.S. Government and its allies at the Farnborough International Airshow.
