Founder of Rotron Engines, Gilo Cardozo, gave a sparkling account of the small super charged Wankel rotary engine in the backpack propulsion units that took him and Bear Grylls on their record breaking paraglider flight to the summit of Everest in 2007. Development continued with MoD contracts for UAV engines. Rotron has been able to take advantage of technological advantages not available to the early Wankel manufacturers, notably ceramic seals and sophisticated machine tools available at much lower cost. A significant design advance has been the dual intake system enabling improved cooling of the engine's centre, the primary intake port forcing a controlled air/oil mist through the rotor. The result is an engine which overcomes the long standing prejudices against the rotary engine; high oil consumption, high apex seal wear and poor fuel consumption. Sfc is now around the same level as a comparable four - stroke engine and the advantages of compact size and incredible power to weight ratios are coupled with inherently low vibration.
