  • Podcast Ep. #42 – Autonomous Helicopters with Near Earth Autonomy

    Dr Sanjiv Singh is a research professor at the Robotics Institute of Carnegie Mellon University and the CEO of Near Earth Autonomy. Sanjiv has more than 30 years of research experience in the field of autonomous vehicles and has spun-out multiple companies from his university research.

    His current venture, Near Earth Autonomy, develops technology that allows aircraft to autonomously take-off, fly, and land safely, with or without GPS. Near Earth’s goal is to develop complete autonomous solutions that improve efficiency, performance, and safety for aircraft ranging from small drones up to full-size helicopters. The team at Near Earth was awarded the 2018 Howard Hughes Award, which recognises outstanding improvements in fundamental helicopter technology, and was also a 2017 finalist for the Collier Trophy, one of the most important aviation awards worldwide. In this episode of the Aerospace Engineering Podcast, Sanjiv and I talk about:

    • his background as a researcher in the field of robotics and autonomy
    • the fundamental concepts of autonomy
    • the hardware and software that make it work
    • the successful helicopter technology demonstrator Near Earth Autonomy has developed
    • and the future of autonomous vehicles

  • Podcast Ep. #14 – Dufour Aerospace Co-Founder Thomas Pfammatter on the aEro2 VTOL Electric Aircraft

    On this episode I am speaking to Thomas Pfammatter, who is the co-founder of the Swiss electric aircraft startup Dufour Aerospace. Dufour is currently designing an electric aircraft with vertical take-off and landing (VTOL) capabilities for the urban and rural transport market. The promise of their current aircraft, the aEro 2, is that with VTOL capabilities it can take-off and land pretty much anywhere, which can considerably reduce travel times, especially to places that are difficult to reach by car or train.

    There is a long-standing compromise in aviation between taking-off vertically, and being able to travel fast horizontally. Dufour Aerospace believes that with electric propulsion it is possible to combine these two worlds. To achieve this, Dufour are using a tilt-wing design fitted with two propellers. The wing and attached propellers can pivot around a hinge between the horizontal and vertical planes, and thereby provide exceptional lift, stability and control characteristics even in slow flight. Dufour have proven their electrical aviation ambitions with the aEro1 aerobatic aircraft and are currently in the process of developing the tilt-wing aEro 2 airplane. In this episode you will learn about many of the details behind Dufour’s technology such as:

    • the tilt-wing concept and the tail fan used for pitch control
    • the aerodynamic importance of the vortex ring state
    • the future of regional travel and how Dufour hopes to influence this space
