DEHARDE GMBH

Their core work

DeHarde is a German SME specializing in precision wind tunnel model manufacturing and aerodynamic testing services for the aerospace industry. They build high-fidelity physical models for wind tunnel campaigns and complement experimental work with CFD (Computational Fluid Dynamics) simulations. Their H2020 portfolio shows consistent involvement in Clean Sky 2 projects focused on nacelle design, aerodynamic characterization, and flight-condition testing for next-generation aircraft configurations including tilt rotors and ultra-high bypass ratio engines.

What they specialise in

How they've shifted over time

DeHarde's H2020 involvement is concentrated in a tight 2018–2019 window, making long-term evolution hard to trace. Their earlier projects (PRODIGE, BinCola) focus on conventional fixed-wing aerodynamic characterization — hinge moment loads and laminar flow nacelles. The later projects (TRINIDAT, IVANHOE) shift toward more advanced configurations: tilt rotor inlets and ultra-high bypass ratio nacelles, suggesting a move toward next-generation aircraft architectures.

DeHarde is moving from traditional fixed-wing aerodynamic testing toward advanced propulsion integration (UHBR engines, tilt rotors), positioning them for future vertical lift and hybrid aircraft programs.

How they like to work

DeHarde operates exclusively as a participant — they have never coordinated an H2020 project. With 14 unique partners across 4 countries in just 4 projects, they join moderately sized consortia as a specialist contributor providing wind tunnel models and test capabilities. This is a typical profile for a precision engineering SME that is brought in for specific testing competences rather than driving the research agenda.

DeHarde has worked with 14 distinct consortium partners across 4 European countries, entirely within the Clean Sky 2 ecosystem. Their network is focused on the European aerospace supply chain, centered on airframers, engine integrators, and research labs working on next-generation propulsion.

What sets them apart

DeHarde bridges the gap between computational aerodynamic design and physical wind tunnel validation — a critical step in aircraft development that few SMEs can provide at this level. Based in Varel (Lower Saxony, near major German aerospace hubs), they offer the rare combination of precision model manufacturing and hands-on test expertise. For any consortium needing experimental aerodynamic validation of nacelles, inlets, or flight surfaces, DeHarde is a proven, flight-program-ready partner.

Highlights from their portfolio

• TRINIDAT
  Largest budget (EUR 1M+) and most technically diverse scope — tilt rotor inlet design covering CFD, wind tunnel testing, icing certification, and variable inflow conditions.
• IVANHOE
  Focuses on ultra-high bypass ratio nacelle optimization using combined high-fidelity and multi-fidelity methods, directly relevant to next-generation commercial engines.
