#39 – Exosonic is Developing a Low Boom Supersonic Passenger Aircraft

Norris Tie is the CEO of Exosonic, a California-based startup that is developing a low sonic boom supersonic passenger aircraft. Norris holds an engineering degree from UCLA, an MBA from Stanford, and before starting Exosonic worked on supersonic aircraft at Northrup Grumman, Virgin Galactic and Lockheed Martin Skunk Works. What differentiates Exosonic from other upstarts in the reviving supersonic aircraft space is that the company is specifically focusing on reducing the intensity of sonic booms. Current regulation forbids supersonic flights across America to minimise noise pollution; a restriction which significantly limited the routes that the first supersonic airliner, the Concorde, could fly. To soften sonic booms, Exosonic is using a concept and technology originally pioneered by NASA known as shaped sonic booms. As a first step, Exosonic has partnered with the US Air Force to develop a supersonic executive transport aircraft that will provide US leaders and diplomats rapid transportation around the world. In this episode of the Aerospace Engineering Podcast, Norris and I talk about

• his life-long inspiration for speeding-up air travel
• the theory behind shaped sonic booms
• what is different about designing supersonic aircraft
• and the economics of supersonic flight

#38 – Momentus is Developing a Transfer Vehicle for Space

Alexander Wicks is the Chief Development Officer at the California-based startup Momentus Space. Momentus is developing the in-space equivalent of the connecting flight we all know from airline operations. To affordably launch small satellites into orbit, operators and manufacturers of small satellites are generally forced to share a ride on one big rocket. This approach is economical, but has one major downside: not every satellite on the ride share can be launched into its ideal orbit. Momentus is developing the transfer vehicle that then allows a satellite to reach its customisable orbit 10 times cheaper than booking a dedicated launch on the first vehicle. This capability essentially allows the next generation of satellites to reach previously unreachable locations more efficiently and more inexpensively than before. The transfer vehicle that Momentus is developing is powered by water plasma propulsion, and the same propulsion technology also opens the door to the next phase of space exploration. For example, missions into deep space, water prospecting and delivery throughout the solar system, in-space manufacturing, and space tourism. So in this episode of the podcast you will learn about:

• how Momentus got started
• the need and benefits of Momentus' transfer vehicle
• the principles of water plasma propulsion
• and the types of missions the technology enables

#37 – Anomalous is Using AI to Make Inspection More Accurate

Today I am speaking with Euan Wielewski, co-founder and CEO at Anomalous Technologies. Anomalous is a start-up based in Edinburgh, Scotland that uses the latest machine learning and artificial intelligence (AI) technologies to enable better quality control of manufactured components. As aerospace engineers we know that quality control and inspection of flight-critical hardware is essential for guaranteeing safe operation of aircraft. Human visual inspection is a subjective and analogue process, which means that flight hardware is typically double and triple-checked to high levels of accuracy. This is where the AI tools developed by Anomalous Technologies are invaluable. By making inspection digital, operational traceability is immediately enhanced. Furthermore, digitisation allows the human inspection process to be accompanied by statistical tools that reduce the error rate of missed defects and improve inspection efficiency. Anomalous are already working with global aerospace companies such as Rolls Royce and Boeing, and the company is currently a member of the first cohort of the ATI Boeing Accelerator. In this episode of the podcast, Euan and I talk about:

• his broad background in aerospace engineering
• the challenges of human inspection
• how data-centric methods such as AI tools can help improve inspection accuracy and efficiency
• and how Anomalous is using their analytic tools to help out in the current Coronavirus pandemic.

#36 – ZeroAvia is Powering Sustainable Aviation with Hydrogen

Sergey Kiselev is the Head of Europe of the sustainable aviation company ZeroAvia. ZeroAvia is working on the first practical zero-emission aviation powertrain fuelled by hydrogen. Even though CO2 emissions of the aviation industry currently only account for 2-3% of the global output, passenger numbers are expected to grow continuously for the next 30 years, such that solutions transitioning to emission-free powertrains need to be formulated, tested and certified now. ZeroAvia has developed a new powertrain that couples hydrogen gas with a fuel cell to drive an electric motor that spins a propeller. This zero emission powertrain currently promises to deliver a 300 mile zero-emission range in a ten-seater fixed-wing aircraft. One of the great things about ZeroAvia is that the company is taking advantage of the economics of renewable energy sources. Due to the intermittency of solar and wind energy, there are times when the electric output from renewable sources far outstrips demand and is therefore cheaply available. It is in these times of high supply that ZeroAvia can split water into its constituents, oxygen and hydrogen. In this episode of the aerospace engineering podcast, Sergey and I talk about:

• how ZeroAvia got started and what the company is trying to achieve
• ZeroAvia’s vision of emission-free regional travel
• the ZeroAvia powertrain
• and much, much more.
