  • Surfaces functionalized with lasers / 2020

    A fast, ecofriendly way of de-icing aircrafts

    Ice on an aircraft’s surfaces can be a hazard. It increases drag and fuel consumption, disrupts aerodynamic flows, and decreases lift – which impairs the aircraft’s ability to fly safely. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS, AIRBUS and TU Dresden have developed a laser process that fills two needs with one deed. On one hand, accumulated ice falls off by itself and on the other it takes less heat to de-ice surfaces. Direct Laser Interference Patterning permits surfaces to be structured in ways that effectively repel ice.

    Microlaunchers are an alternative to conventional launch vehicles. Able to carry payloads of up to 350 kilograms, these midsized transport systems are designed to launch small satellites into space. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden and TU Dresden’s aerospace experts developed an additively manufactured rocket engine with an aerospike nozzle for microlaunchers. The scaled metal prototype is expected to consume 30 percent less fuel than conventional engines. It will feature prominently at the Hannover Messe Preview on February 12 and in the showcase at booth C18 in hall 16 at the Hannover Messe from April 20 through 24, 2020.
