70 T he Eurosatory trade show, held every two years at the Parc des Expositions de Villepinte near the Paris Charles de Gaulle airport in France, is the largest international exhibition in the world for land and air defence technology. The 2018 event brought together more than 1800 exhibitors from 63 countries, and over 57,000 visitors to view the latest innovations in cost-effective military technology. Magam Safety has developed technology that enables a fuel tank to re- seal itself automatically when punctured by shrapnel or bullets, to prevent any significant leakage of fuel. The system can be applied in flexible ‘bladder’ or rigid tanks. “The key to this self-sealing is a multi- layered rubber sheet, which we can manufacture between metallic or flexible materials,” said Col Meir Gilady. “We add some proprietary components into the rubber, so that when it comes into contact with fuel, and the ‘shock’ of a bullet or piece of shrapnel is applied, it reacts at the location of the shock by expanding until the puncture is sealed.” For UAVs or UGVs operating in potentially dangerous areas, the solution provides a weight-saving alternative to armour systems for ‘bulletproofing’ fuel tanks. MTC Industries has designed an electromechanical landing system for medium-altitude, long-endurance unmanned systems. “It is intended to replace the hydraulic landing systems that such aircraft tend to use at the moment,” said Yair Avni. “Electromechanical systems are lighter, easier to maintain and more reliable than hydraulics. We’ve also installed redundancies throughout the system, with dual servo actuators, dual coil electrical motors, dual coil electromechanical tooth brakes and dual control units.” The system enables opening of landing gear doors, extension of the landing gear and then locking them with the tooth-brake (and in reverse as well).
