Already a subscriber?In January, more than 100 people gathered at a plane hangar in California to watch NASA unveil its X-59 demonstrator jet. The futuristic aircraft designed to travel faster than the speed of sound has helped revive excitement for supersonic travel.
The sonic boom is about 105 PLdB, or perceived level of decibels, similar to that of the sound of a balloon popping next to you. In comparison, NASA says the X-59’s will sound closer to a car door slamming 20 feet away. Denver-based Boom Supersonic is eyeing 2029 for the debut of its supersonic passenger jet, called Overture. The aircraft is expected to seat 64 to 80 passengers, according to Blake Scholl, the company’s chief executive. It will travel at Mach 1.7, or 1.7 times the speed of sound – more than twice as fast as a regular passenger planeA illustration of what Boom Supersonic’s Overture jet might look like. It would fly at 1.7 times the speed of sound.
Bruce McClelland, a senior contributing analyst at aerospace and defence industry analysis firm the Teal Group, says: “A lot of projects attract money whether they’re completely viable or not.”Companies say their new generation of supersonic jets will have a smaller carbon footprint, mostly because they will be fuelled by sustainable aviation fuel. This is fuel is made from agricultural products including soybeans and animal fat.But critics say that pledge ignores some significant realities.
They point to Tesla and the burgeoning space tourism sector as an example of new modes of transportation that have and could eventually become accessible to a growing segment of the population.
