80% time savings at tests in wind tunnels in cryogenic or high speed facilities

AIAA Scitech Conference, Orlando

At the AIAA Scitech Conference in Orlando, Boeing presented the results of a project for the development of Remote Control Actuation (RCA) in cryogenic wind tunnels. The project is a cooperation by Boeing, NASA, Deharde and the ETW, a company that operates a cryogenic wind tunnel to investigate the aerodynamic characteristics of airplanes.

Currently, the configuration changes cause expensive interruptions during each test phase especially under cryogenic and high speed conditions. The project aims to eliminate these interruptions and highly increase the efficiency of the test campaigns. Extreme cost saving is the direct result of the use of RCA.

For the project, Deharde built a new wing of a 787 half model with several remote-controlled control surfaces (spoiler and aileron). The results of the project was a successful use of RCA technology: up to 80% test time reduction could be achieved for tests under cryogenic and cruise conditions.

On the long term, the new RCA based technology shall be made standard for wind tunnel testing. This vision clearly has become closer to reality now. Due to this, the participants not only will continue their research work, but will also start to introduce the advantages of RCA technology to the industry and create surroundings to bring RCA into service on a standard basis.

Uwe Fresenborg strengthens the management of Deharde.

Deharde succeeded to win an experienced Top manager with industry experience for the reinforcement of the management.

Mr. Uwe Fresenborg will become active starting from 01.11.2019 as third managing director with Deharde and will take over the presidency of the management.

After studying aerospace, Mr. Fresenborg worked for Airbus for 18 years in various program and engineering functions. In 2009 he took over the plant management of Premium Aerotec in Varel for three years.

In 2011, Mr. Fresenborg was appointed to the Management Board of Deutsche Bahn Fahrzeuginstandhaltung GmbH and took over as Chairman of the Management Board until his retirement in summer 2019.

We are looking forward to the future cooperation and are happy to welcome such an experienced manager with corresponding industry knowledge on board at Deharde.

Successful application for Deharde Polygon Forming® trademark

Technical, quality and cost advantage in sheet metal forming: useful innovation for the construction of aeroplanes

Deharde Polygon Forming® has now officially been registered as a trademark. Deharde Polygon Forming® is an innovative method used in the aviation and space industry to manufacture skins and other metal forming components. It stands out to cost-efficiency and very high quality. Metal sheets can be curved in cylindrical, conical and twisted form. Drills, pockets, cut-outs etc. can be done in flat condition with 3-axis-machines. Compared to conventional roll forming, where expensive 5-axis machines with complex clamping devices and long lead times are required, remarkable cost benefits can be realized. After bending with Deharde Polygon Forming® the dimensional accuracy is warranted. Forming process is performed in one throughput, with high repeat accuracy and 100% NC controlled. The high-quality polygon-formed products are already on duty in aviation and space.

Deharde drives forward focus on aircraft structures

Bremen location is sold and continued as an independent company under the names ED Oberflächenveredelung and ED Metallbearbeitung

The medium-sized company Deharde GmbH sells its subsidiaries Deharde GmbH Bremen Operations and HDD GmbH, which specialize in housing construction and surface protection. The buyer of both companies is the Dutch South Wind Treasury B.V. from Ter Apel, which has appointed Mr. Michael Köhler as the new managing director for both companies. In future, Deharde GmbH Bremen Operations will trade under the name ED Oberflächenveredelung GmbH and HDD GmbH under the name ED Metallverarbeitung GmbH.

Bremen/Varel, 02 September, 2019 Deharde GmbH has grown strongly in recent years in its strategic business fields of aircraft structures, plant engineering and wind tunnel model construction. Deharde will focus on these strategic business areas in order to be able to meet the increased customer requirements in the future. The production site in Bremen, which focuses on housing construction and surface finishing, was therefore sold to South Wind Treasury B.V. The company will continue to focus on these strategic business areas in the future. All current employees of both companies will be taken over.

About Deharde GmbH: Deharde GmbH is a medium-sized company with about 300 employees. Deharde develops, manufactures and installs wind tunnel models, production equipment and aircraft assemblies for all well-known OEMs.
