Sam Bousfield is the founder and CEO of Samson Sky, a company that is developing the first truly useful flying car. Sam is an architect by training, but a passion for aviation led him to work on a supersonic aircraft with Boeing. Out of this experience came the idea of building a flying car called the Switchblade. Harking from an architectural background, Sam approached the problem of designing a flying car slightly differently. Rather than asking the question of how you could make a car fly, Sam and his team focused on the architectural question of how a vehicle that can both fly and drive should be designed. Answering this question led the Samson team to some unique design choices, such as a three-wheel layout and wings that stow and swing out from underneath the vehicle. One of the other challenges in designing a flying car is striking the right compromise between on-road and off-road performance. For example, a car should preferably create downforce, while a plane should create lift. To achieve this Samson Sky has made some very clever design choices in terms of the layout and shaping of the Switchblade, as well as the positioning of the wings and centre of gravity, and the use of lightweight composite materials. In our conversation, Sam and I talk about: why it has taken so long for a functional flying car to be built the main design challenges that need to be overcome the changes that need to be made to the vehicle when switching between flying and driving the way that Sam envisions the Switchblade to be used in practice and much, much more.

Aleksey Matyushev is the co-founder and CEO of Natilus, a startup headquartered in San Francisco. Natilus has set out to reduce global air freight costs through the use of large autonomous drones, and has moved quickly over the last couple of years to develop a sea-plane prototype to serve as a technology demonstrator. The engineers at Natilus are now moving ahead at full steam to design a land-based freighter drone based on a blended-wing body. As the name suggests, a blended aircraft has no clear demarcation line between wings and fuselage. Advantages of this approach are efficient lift generation aided by the wide airfoil-shaped body, allowing the entire aircraft to generate lift. This means that a blended wing body has better lift-to-drag ratios than a conventional aircraft, resulting in improved fuel efficiency. One particular challenge, however, is that a blended wing body does not feature a vertical and horizontal tail, and this makes controlling the aircraft particularly challenging. In this episode of the Aerospace Engineering Podcast, Aleksey and I talk about: his educational journey to becoming an expert aerodynamicist the technical details of the freighter drone Natilus is designing Natilus’ business model and near-term developments that are in the pipeline Last but not least, Natilus is currently hiring for a number of roles.

In this episode I am speaking to Bertrand Flipo from The Welding Institute in Cambridge, UK. TWI Ltd has a long history of innovation in welding research, having been established as the British Welding Research Association in 1946. TWI Ltd is a world leader in research on friction welding and has been at the forefront of many modern friction welding processes. Briefly put, friction welding is a joining technique that does not melt the parts to be joined. Instead, two components are rubbed together to create heat through friction, and high pressure is then applied to squeeze the two pieces together. During this process the material plastically deforms and the high pressure causes the components to be fused together. Advantages of the process are fast joining times, typically on the order of a few seconds; relatively small heat-affected zones; and because friction welding techniques are melt-free, the material's microstructure can be maintained. I personally learned a lot during the recording of this episode, and Bertrand and his colleagues were very gracious to introduce me to the ins and outs of friction welding. So in this episode you will learn about: the differences between different friction welding techniques the main advantages of friction welding and the challenges to keep in mind some of the aerospace applications where friction welding is a game-changer and much, much more If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

On this episode I am speaking to Luca Leone who is the Head of Programme of AERALIS, a British startup designing a new class of military trainer and aerobatic jet aircraft. AERALIS have set out to re-invigorate the UK aircraft manufacturing sector with a military trainer that provides an exceptional pilot training experience. AERALIS' design is purposely modular meaning that a basic and an advanced version of the training aircraft are based on one common platform. This reduces costs in engine and airframe maintenance through training and spares commonality and also facilitates a shorter training period for pilots due to similarities between aircraft types. What’s more, AERALIS are developing a fully tailorable flying training system based on configurable cockpits and advanced simulators. In this way, AERALIS aim to not just be an aircraft manufacturer but a company that designs the total flying training experience. In this episode, Luca and I talk about: the features of the basic and advanced trainer aircraft the characteristics of the modular design the AERALIS training ecosystem and much, much more If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

Veronica Foreman is a payload engineer at the small-satellite launch provider Virgin Orbit. Before starting her career at Virgin Orbit, Veronica earned several academic accolades including an Outstanding Undergraduate Researcher Award at Georgia Tech, and a Best Masters Thesis award at MIT. What I find especially impressive about her Masters work on small-satellite constellations is that Veronica considered both the design of constellations, as well as the economic and policy challenges to small-satellite mission success. As Virgin Orbit's mission is to be the premier dedicated launch service for small satellites, Veronica has seemingly found the perfect place for her expertise and passion. One of the key features of Virgin Orbit's launch design is its air-launching system that drops the rocket (LauncherOne) from the wing of a Boeing 747 (Cosmic Girl), providing a movable launchpad. As Veronica explains in this episode, this capability provides Virgin Orbit unique advantages in terms of providing a dedicated launch service for small satellites. In this episode of the Aerospace Engineering podcast, Veronica and I discuss: Virgin Orbit's vision the unique advantages and challenges of an air-launched rocket system some of Virgin Orbit's key engineering technologies and the growing importance of satellite constellations If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

Samy Libsig is one of the founders of the sport aircraft startup eXalt Aircraft Inc. eXalt currently comprises a team of three engineers that are bringing a unique combination of fresh design thinking and engineering experience to the world of sport airplanes. The vision of eXalt is to turn the sky into a playground with an aircraft that puts the pilot's flying experience in the foreground. This means an aircraft which is fun to fly, economical, maintenance friendly, and environmentally sustainable. Looking at the sport aircraft market, it is easy to notice that aircraft designs haven't evolved appreciably over the last couple of decades. This is probably for a good reason given that the laws of flying are obviously unchanged, and the design principles that worked in the past, are still valid today. But what is particularly fascinating is the manner in which eXalt Aircraft are using proven aerospace technologies and recombining them in novel ways to design an entirely modern aircraft. The result is an airplane that does not feature all of the most recent bells and whistles—just for the sake of using cutting-edge technology—but instead features a pragmatic design where each component has been carefully chosen to serve the company's vision of maximising the pilot experience. As you will hear in this episode, one of the best examples of this is eXalt's choice of a reinforced spaceframe design over an arguably lighter monocoque design. In this episode of the podcast, Samy and I talk about: the origins of eXalt their particular design philosophy some of the key design choices they have made and the near future of the company If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

Mark Crouchen is the managing director of Rockwood Composites, a company in the UK that specialises in manufacturing complex composite components using compression and bladder moulding. These manufacturing processes use fibre mats of carbon fibre, glass fibre, Kevlar, or any other material, which are pre-impregnated with a resin matrix and then placed in a mould, where they are cured at elevated temperature with the addition of external or internal pressure. The team at Rockwood has been supplying the aerospace, defense, medical and nuclear industries for over 25 years, with customers ranging from Leonardo Helicopters and the McLaren Formula 1 team to Safran and Facebook’s Aquila internet drone. In 2018, Rockwood won the Innovation in Manufacture award at the Composite UK industry event for their innovative use of advanced composite materials on the Tokomak ST40 nuclear fusion reactor. Composite materials have many benefits in terms of their excellent strength and stiffness at low weight. However, there is a common misconception that metal or ceramic components can easily be replaced one-to-one with composite components. The performance of any composite component is closely linked to the quality of the manufacturing process, and designing and manufacturing quality components is an area where Rockwood Composites particularly excel. In this episode of the podcast, Mark and I talk about: his background in engineering the types of structures that Rockwood Composites manufacture why composites manufacturing is a challenge and the special solution Rockwood found for the Tokomak ST40 fusion reactor If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

Paul Withey is the Professor of Casting at the School of Metallurgy and Materials of the University of Birmingham, UK. Before joining the University of Birmingham in 2018, Paul worked at Rolls Royce for 21 years developing new superalloys and manufacturing processes for gas turbine components. As an Engineering Associate Fellow, Paul was a member of a select group of the top 100 specialist engineers across all engineering disciplines within Rolls Royce, and in 2015, Paul and his team were awarded the highest technical award within Rolls-Royce; the Sir Henry Royce Award. Paul’s particular expertise lies in investment casting of aerospace metals, especially of high-temperature superalloys used in the hot turbine stages of modern jet engines. Throughout his career at Rolls-Royce, Paul has developed and optimised manufacturing processes for single-crystal turbine blades with a total of 14 patents to his name. Despite phenomenal advances in materials technology, a number of questions with regard to how the turbine blade shape, materials and process parameters interact remain unanswered, and these questions form the basis of Paul’s ongoing research. In this episode, Paul and I discuss: the unique differences between research in academia and industry what single-crystal superalloys are and how they are manufactured why single-crystal superalloys are a critical technology for modern jet engines and the research questions that Paul is currently trying to answer If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.

Oliver Family is the Overall Aircraft Design Leader of the Airbus E-Fan X demonstrator. The E-Fan X is a hybrid-electric technology demonstrator being developed by Airbus, Rolls-Royce and Siemens based on a British Aerospace 146 regional airliner. The driver behind the E-Fan X demonstrator is that current aircraft designs have converged to a near-optimum, and with existing technologies, it is difficult to meet the stringent sustainability goals in terms of CO2/NOX emissions and reductions in noise. New technologies, such as electrification, are therefore required to achieve these goals. As we have seen on other episodes of the podcast, electrification of aircraft is currently a hot topic with new start-up companies promising to disrupt and revolutionise the regional aircraft market. In this environment, one may assume that incumbents like Airbus are too slow to react to a changing technology landscape. As you will hear in this episode, nothing could be further from the truth. The E-Fan X project is structured as a separate entity within Airbus with the explicit mission of challenging Airbus’ legacy business. As you will hear, the consequences of integrating an electric propulsion system on a regional aircraft run much deeper than mere calculations about battery power density and battery longevity. In fact, it's the secondary effects that we rarely think, hear and read about, such as thermal management of batteries; the interaction between pilots and new control systems; and the challenges of new certification protocols, that are especially challenging. So in this episode, Oliver and I discuss: what exactly the E-Fan X demonstrator aims to achieve the main technical and economic challenges of electric aircraft and how electrification widens the design envelope for engineers If you enjoy the Aerospace Engineering Podcast you can support it by leaving a review on iTunes or by supporting it directly on Patreon, where patrons of the podcast receive exclusive behind-the-scenes content and special episodes.
