Boom says its supersonic XB-1 aircraft test program will be ‘fully carbon neutral’

Published February 24, 2020

Commercial aviation isn’t typically the place to look if you’re after carbon-light initiatives. Jet fuel isn’t generally very green, and airplanes burn a lot of it when traversing the skies. But supersonic flight startup Boom wants to change the perception of commercial aviation as an emissions-costly prospect, starting with their testing development program for the XB-1 supersonic demonstration aircraft that will eventually lead to the development of its Overture passenger aircraft.

Boom claims this will make it the first commercial flight OEM to achieve this level of sustainability, especially from the very beginning of its aircraft flight testing and certification process. And while XB-1 and eventually Overture aren’t electric or hybrid aircraft, the way the company hopes to achieve this milestone is through a combination of using sustainable jet fuel and carbon offsets (effectively the process of buying carbon “credits” by funding projects that net reduce greenhouse gases) to reduce its overall carbon footprints to zero.

The fuel that Boom is using comes from partner Prometheus Fuel, which is a company that uses electricity from renewable power sources, like solar and wind, to turn CO2 scrubbed from the air into jet fuel. Already, Boom has tested this fuel in use during some of its initial ground tests, and its findings indicate that it should be able to use it effectively through both the remainder of ground testing, as well as into its flight program.

While there is some debate about the overall validity and efficacy of carbon offsets, provided that money from these programs is funneled into the proper initiatives, they do seem to result in more ecological good than not. And any attempt to offset the economic impact of a flight program like Boom’s, especially if it’s carried through to flying production aircraft, should be better for the environment than had no attempt been made whatsoever. Which, by the way, is the case for most new aircraft development programs.

Already, Boom is in the process of building the XB-1, which it will then flight test in partnership with Flight Research during a program in the Mojave Desert at the Mojave Air and Space Port. The goal is to begin testing this summer, and eventually use the information gathered from the XB-1 program (which will be able to hold a pilot but no passengers) to build out the final Overture aircraft that will offer commercial passenger supersonic flight services. Boom has secured agreements with a number of airlines for pre-orders for Overture, including JAL and Virgin.

NASA’s first all-electric experimental X-plane is ready for testing

Published October 3, 2019

NASA will fly a crewed X-plane, one of the experimental aircraft it creates to test various technologies, for the first time in two decades in the near future. This X-plane, the X-57 Maxwell to be exact, is significant for another reason, too: It’s the first fully electric experimental plane that NASA will fly.

The delivery of the X-57 Maxwell to NASA’s Armstrong Flight Research Center in California means that they can begin ground testing, which will then be followed by flight testing once they confirm through the ground testing phase that it’s flight-ready. This all-electric X-57 is just one of a number of modified vehicles that will not only help NASA researchers test electric propulsion systems for aircraft, but will also help them set up standards, design practices and certification plans alongside industry for forthcoming electric aerial transportation options, including the growing industry springing up around electric vertical take-off and landing aircraft for short-distance transportation.

NASA plans to share the results of its testing and flights of the all-electric X-57, as well as its other modified versions, with industry and other agencies and regulatory bodies. The X-plane project also provides another way for NASA to work towards a number of technical challenges that will have big benefits in terms of everyday commercial aerial transportation, like boosting vehicle efficiency and lowering noise to develop planes that are far less disturbing to people on the ground.
