V-tail Without the need for a large vertical rudder for asymmetric handling, the tail and empennage can be lightened with a V-tail configuration, saving 3,000kg in weight. Rear propulsor The IP2 would feature dual contra-rotating ducted fans, powered by brushless electric motors that would encircle the rear fuselage. Not having to protect or reinforce the fuselage against uncontained fan-blade separation from wing-mounted engines would also save weight.

Conseil et Technique envisages a ‘plug & play’ solution to quickly recharge or swap battery packs at airports, as well as being able to shift the packs internally before flight to account for different pay- loads and CoG. AIR TRANSPORT Electric tailspin French engineering and design consultancy Conseil et Technique has revealed a concept for an electric-powered A320-sized airliner, the Integrated Propeller Plane (IP2), that shifts the engines from the wings to an integrated propulsion fan around the tail driven by brushless motors. As well as zero-emissions, Conseil et Technique says that, by relocating the engines from the wing, this will reduce 8,000kg of structural weight, eliminate asymmetric handling problems on take-off, enable laminar-flow wings and also remove uncontained engine fan blade issues. Using today’s battery efficiency of 0.15kWh/kg, the firm says that the IP2 would be able to fly for 78 minutes, rising to 323 minutes with 0.4kWh/kg batteries, expected to be available in five years time. IP2, says the company, could also be adapted to use hydogen propulsion.

Scientists around the world are still studying rocks and soil samples that were collected, by the Apollo 11 through 17 missions, using modern equipment, methods and technologies. The return of samples has allowed the field of planetary science to advance in ways unthinkable with the restrictions of in-situ analysis and remote observations. As for every other aspect of the Apollo programme, the design and manufacturing of the tools uti- lized by astronauts for sample collection had to meet rigorous planetary protection requirements, whilst respecting stringent environmental and operability constraints. Many of those tools went through various redesign efforts, based on feedback from the very skillful and resourceful astronauts using them. In future planetary exploration missions, geological and geo-microbiological sampling will be a key to further devel- opment of our understanding of the evolution of the solar system, and to develop successful technologies for in-situ resource utilization and 3D printing.
