4 Unmanned aircraft are maturing, with airborne technology looking at new ways to provide long range, safe operation and surveillance capabilities. From the solid oxide fuel cells developed for small UASs by Adelan (page 62), to the Phoenix unmanned airship on page 22 and redundant power systems for hybrid VTOL in our power management focus on page 88, longer range is at odds with the increased need for ensuring reliable, safe operation. This need for dual redundancy is also pushing the design of driverless cars. Adding redundant systems adds weight and complexity but provides safe operation beyond visual line of sight. That is especially important in the construction industry, as we highlight on page 44. Handling challenging environments is also a key requirement of unmanned systems. Supacat has designed its UGV (page 56) for the armed forces, while on page 82 we explain how Copperstone’s screw-based propulsion system is powering its USV for monitoring the often toxic waste ponds around mine sites. Meanwhile, sonar technology is driving the design of larger unmanned underwater vehicles (UUVs). On page 36 we look at how it is helping the vehicles to accommodate higher resolution systems. All this highlights how the design of unmanned systems is moving from demonstrating their potential to ensuring that they can operate safely across a wide range of environments and conditions.
