Multicopters Made From Renewable Lightweight Materials
Sustainable | Efficient | Qualified
Leichtwerk AG has developed a highly innovative concept for multicopters with ultra-light structural designs made of renewable lightweight materials, such as wood and natural fiber-reinforced bioplastics. In the research project HerMes, this concept is being implemented as a prototype together with excellent partners. More…
As a system house, Leichtwerk AG works on the latest technologies in various disciplines related to unmanned flight, e.g. lightweight construction, control rooms, concepts of operation. The focus lies on qualified hardware and software solutions that find their way directly into the industry in concrete applications. State-of-the-art design and manufacturing processes are used for the developments, always taking into account relevant legal regulations, such as CE or EASA guidelines.
Leichtwerk leads the HerMes project and handles the aeronautical development of the multicopter, including structural design, avionics systems, prototype construction and testing.
Sustainability through the utilization of renewable raw materials has formed the focus at the Fraunhofer WKI for 75 years. The institute, with locations in Braunschweig, Hanover and Wolfsburg, specializes in process engineering, natural-fiber composites, binders and coatings, wood and emission protection, quality assurance of wood products, material and product testing, recycling procedures and the utilization of organic building materials and wood in construction. Virtually all the procedures and materials resulting from the research activities are applied industrially.
I the HerMes project, the WKI is developing new manufacturing processes and high-performance composites based on renewable raw materials, including wood veneer and natural fiber laminates as well as fiber-reinforced injection molding compounds.
As a medium-sized family-owned company, Jowat SE is one of the world’s leading manufacturers of adhesives, including dispersion adhesives, hot melt adhesives, reactive 1K and 2K systems, and pressure sensitive adhesives. The focused application areas are the wood, furniture and construction industries, the paper and packaging sector as well as the automotive, textile and electrical industries. A team of more than 50 researchers is continuously engaged in the development of innovative products. An increasingly important focus of research is the investigation of renewable raw material sources for adhesives.
In HerMes Jowat supplies and investigates adhesive systems for joining multicopter components. Selected systems are being further developed to improve sustainability by increasing the proportion of renewable raw materials.
