4 In this issue we look at the challenges of developing reliable unmanned systems for a wide range of applications. With legal operations beyond visual line of sight (BVLOS) on the way, UAVs will become suitable for a greater variety of tasks, as we highlight on page 46, looking at how new technologies are being integrated into existing platforms to enable new use-cases. Our cover story on the Hummingbird XRP takes that forward, by looking at the way a platform can be developed using many rounds of testing to reach the most flexible design. We also discuss a new radial engine design for helicopter-type UAVs, on page 64. When autonomous systems are used for so many applications, monitoring the platforms becomes even more important to ensure the systems can be used reliably. As we explain on page 82, machine learning and connections to the cloud are playing a growing role in monitoring the performance of ground systems and for tapping into the battery packs and autopilots of UAVs. There is an irony here though that this is increasing the complexity of the system, and therefore potentially lowering its reliability. But monitoring the performance of an unmanned system in more detail, regardless of the application, gives engineers greater confidence that it can predict when it needs to return to base before a problem occurs. That confidence will be a key part of the roll- out of unmanned systems for many applications in the coming years.
