Tony Bishop reports on The Royal Aeronautical Society’s International Light Aircraft Design Competition, which provided stimulating simulations for on-screen air racing. The 2019 RAeS competition was to design an electric air-racer, inspired by Air Race E’s new competition starting up in 2020. With a single pilot and short duration, this is an excellent proving ground for new electric power train technologies. According to the RAES, “The design rules were based on Air Race E, but widened to encourage a broader range of configurations. Air Race E rules include a minimum empty weight of 227 kg, a maximum motor power of 150 kW, fixed pitch propellers, a minimum wing area of 6.132 square meters and a fixed main undercarriage. Air Race …

Several different organizations are trying different ways to keep unmanned aerial vehicles, UAVs, up longer.  We’ll look at three recent efforts in long-endurance missions, each with a unique technological approach. Wirth Research – Hydrogen Fuel Cell Wirth Research is now constructing a new tilt rotor, Vertical Take Off and Landing (VTOL), hydrogen fuel cell powered, advanced terrain-mapping drone.  Carrying a payload of sensors and onboard data processing capabilities, the vehicle will be powered by a complete H2 storage, control and power system provided by HES of Singapore, a specialist in ultra-light hydrogen fuel cells. The Wirth machine’s missions range from precision agriculture, to pipeline and cable inspection for utilities, surveillance and other security-related tasks, through to detection and monitoring support …
