Emirates and Etihad. Is the UK’s exit from the Galileo satellite navigation system a case of a glass half full or half empty? Certainly one can bemoan the £1.2bn sunk costs and future contracts lost by pulling out of a key navigation system that the Features UK helped build and finance – ironically just at the point when it becomes INSRA Airbus operational. However, for some in the UK’s space industry, the chance to develop a GNSS system from scratch, may be a case of a glass half full. The UK space industry has seen its capabilities stretch from satellites, to ion engines, to human spaceflight training, rovers and, soon, launchers and spaceports. What better way to unleash this potential than with a UK GNSS 26 system?

Small model VTOL ‘lifters’ and a tethered model have been flown before, with MIT being first to achieve untethered, sustained flight. Glider launch Launched using a bungee cord, the MIT ‘ion craft’ was flown indoors in a MIT sports hall. It travelled 60m in each flight, with the team flying ten times to repeat the sustained flight. Power storage Lithium-polymer batteries in the nose provide 40,000volts to charge the electrodes via power converter. Specifications Wingspan 5m Weight 2.45kg Speed 4.8m per second 4 AEROSPACE / JANUARY 2019 W AEROSPACE MIT flies ‘ion drive’ aircraft A team from Massachusetts Institute of Technology (MIT) has achieved sustained flight using an electric ‘ion drive’ for the first time. The 10-second indoor flight, using a 5m wingspan subscale demonstrator, uses highly charged (20,000v) electrodes to charge air particles and create an ‘ionic wind’ which provides forward thrust to the aircraft. As well as featuring no moving parts, the propulsion system is silent. While researchers say that passenger aircraft using this propulsion may be decades away, in the nearer term there could be applications for almost silent UAVs. The ionic wind drive could also be paired with hybrid propulsion systems to increase efficiency, according to the researchers. Ion drive Thrust is provided by harnessing electrical electrohydrodynamic (EHD) properties. Two sets of wire electrodes (blue and white in image) are positively and negatively charged, with ionised nitrogen air molecules being accelerated rearwards to collide with neutral molecules to provide forward thrust. The drive, which produces five Newtons for each kilowatt of power, uses no moving parts.
