Beyond the skies – successful launch of Vega C

Deharde parts flying high

Congratulations! Arianespace successfully orbited 53 satellites from spaceport, French Guiana. The mission of Vega flight VV16 is to serve applications including earth observation, telecommunications, sciences, technology/education, and others.

Deharde proudly provided jig and skins for the construction of the Interstage 1/2, a conical structure part that connects the first and second stage of the 30 m high Vega C launcher.

Clean Sky Project TRINIDAT

Delivery of Wind Tunnel Model

We delivered the wind tunnel model TRINIDAT to German-Dutch Wind Tunnels (DNW). The test will begin there by the end of August, 2020, after 2 weeks of test preparation. The model was designed, manufactured and instrumented by Deharde during the last 12 months. TRINIDAT is part of the Clean Sky Projects which deals with the aerodynamic optimization of the intake duct of the Next Generation Civil Tilt Rotor (NGTCR).

Deharde applies for the Productioin Organisation Approval (POA)

Strategic development

To the benefit of our customers, Deharde aims for further qualification and applies for the Production Organisation Approval (POA) at the Luftfahrt Bundesamt, Federal Aviation Authority. With the POA we will be able to enhance our competences within the global aerospace industry: In future, with POA we will be allowed to deliver directly to the final assembly line of aircraft manufacturers.

Siemtje Möller, Member of German Bundestag, visits Deharde

Taking a closer look at present situation

We were happy to welcome Siemtje Möller, Member of the German Bundestag, Gerd Christian Wagner, Mayor of the city of Varel, Dr. Meike Knop, City Management Varel, and Dr. Stefan Berndes from the Bundesverband der deutschen Luft- und Raumfahrtindustrie (BDLI). It was a pleasure to show our guests our company and what we stand for. They were very impressed by our innovative concept of Deharde Polygon Forming®. We had interesting talks about what Covid 19 means for the aerospace industry and what policies might help to enhance the present situation.

Lean Camp

Lean production part of Deharde's continuous improvement

Optimizing processes, easing workflow and enhancing workplaces – lean production is actively stimulated at Deharde. In last week’s “lean camp”, team leaders of Deharde investigated under professional guidance the present processes and conditions in order develop “leaner” structures. In the end, our customers profit of our continuous improvement of internal efficiency!

Deharde involved in Research Project

Objective: Reduction of fuel consumption i.e. of airplanes

Another Clean Sky success story - the BinCola Project („Evaluation of the Benefints of innovative Concepts of laminar nacelle and HTP“) has recently concluded. With Dassault Aviation as topic manager, Deharde, the European Transonic Windtunnel GmbH (ETW) and the Laserline GmbH collaboratively investigated the use of extended laminarity in the nacelles (engine housings) and HTP of a business jet in order to reduce drag and increase aerodynamic performance. The idea is to improve the efficiency of future aircraft by reducing fuel consumption and lowering CO2 and NOx emissions.

Laminar surfaces on airplanes can reduce drag. Surfaces of an airplane usually have turbulent flow but laminar flow only to a minor extend. In addition to the appropriate geometry, highest precision and immaculacy are required to realize laminar flow: At model experiments even a dust particle can change the flow and thus the result of the test.

It is important to pinpoint where the transition occurs between laminar and turbulent flow so the model parts were coated with TSP (temperature sensitive paint). Since the temperature of a surface is different at turbulent and laminar flow, the TSP can show where the surface heat flux is higher or lower. In this way it is possible to distinguish where the flow stays laminar or becomes turbulent, revealing the transition zone.

The following main tasks of the project were performed by the BinCola-Consortium:

  • Manufacturing of a high-precision model- and TSP-surfaces
  • Development and test of different methods to activate the TSP and thus realize visualization of flow
  • Performance of wind tunnel tests using TSP under cryogenic conditions (-163° C)

Dassault was very content with the scientific findings of the BinCola project. Many OEMs of the aerospace industry have already shown great interest in the results of the project. Thanks to the conclusions that can be drawn from the project, future aircraft components can be constructed in a skillful way so airplanes have a better flow and less fuel consumption.
