Chairtracks.

As the pioneer for Chairtracks, Trendelkamp started a new seating experience era in comfort and safety. Patents and ongoing development mark the success of Trendelkamp Chairtracks. These systems can be found in very diverse places and are well known in parliaments, assembly halls, auditoriums and meeting rooms worldwide.

Chairtracks, a device that automatically retracts a chair back to the table after use. It is therefore a fixed yet movable seating solution.

The key benefits of Chairtracks are:

Uniform seating appearance and architectural appeal
Aisles are free from chairs in case of an emergency
Highest seating comfort
New creative opportunities for designers and architects
Flexibility to easily accommodate handicapped access
Reduction in time for rearranging chairs and cleaning floors

Trendelkamp also provides design, spatial planning and project management services to enhance your individual seating challenge.

Federal Eagle Berlin.
Hovers instead of flying.

The federal eagle for the new Germany parliament in Berlin shall appear to be the same as the one from the former parliament in Bonn, except it shall be 50% larger. Also, for the first time, the new eagle will be displayed so that it can be seen on both sides, thus requiring a finished back. The new back portion was designed in cooperation between Trendelkamp and the famous architect, Lord Norman Foster.

Invisible suspension.

The federal eagle consists of four layers of 12 mm thick aluminum. In lieu of attaching to a wall, he is suspended in space. Lord Foster requests that the attachment cables supporting the eagle be hidden and render him static, to prevent swinging. Trendelkamp met the request by developing a piano string suspension that was barely visible with an integrated vibration dampening. The high strength steel wires have a diameter of only 8 mm.
Eagle with slot and key.

In order to transport the eagle from its nest to Berlin, he consists of 3 segments. Most importantly, the joints of each segment should be as invisible as possible. Trendelkamp solved the problem by engineering a slot and key connection that precisely positions each segment during reassembly.

The surface is treated with a special sand blast and coating technology, which was also used on the former eagle in Bonn. The surface is highly sensitive, even a fingerprint would be readily visible, so a special vehicle is necessary for the transportation to Berlin.

In order to transport the eagle from its nest to Berlin, it required the structure be segmented into three sections. Most importantly, the joints of each segment must be completely invisible once the structure is reassembled. Trendelkamp solved the challenge by engineering a slot and key connection that precisely positions each segment during reassembly. The surface of the eagle is treated with a special sand blast and coating technology, not unlike the former eagle in Bonn. The surface is highly sensitive, even a fingerprint would be highly visible, so a special vehicle is necessary for the transportation to Berlin. Upon final completion, Lord Norman Foster and Josef Trendelkamp signed the resulting work.

SOFIA.
A new fastening system for SOFIA's balancer subassembly.

The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a flying observatory and a joint project of the US Space Agency, NASA and the German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR).

Trendelkamp developed a sophisticated fastening system for the telescope's coarse balancer subassembly.

A well balanced telescope.

SOFIA is the largest airborne observatory in the world, capable of making observations that are impossible for even the largest and highest ground-based telescopes. SOFIA carries a 2.5-metre telescope inside a modified Boeing 747SP. This unique airborne observatory performs astronomical observations in the infrared and submillimeter wavelengths, high above the disturbance of Earth's atmosphere. The scientific objective is to understand the development of galaxies and the formation and evolution of stars and planetary systems from interstellar clouds of gas and dust.

The SOFIA telescope weights approx. 17 metric tons and is installed in the rear fuselage section of the highly modified aircraft. The telescope assembly has a hydrostatic oil bearing with the telescope optics on one side and the science instrument on the other. Whenever the science instrument or the telescope configuration changes, the telescope needs to be balanced in all axes by adding or subtracting specific balancing plates to or from the telescope assembly, respectively.

Trendelkamp develops a new fastening system for SOFIA's coarse balancer subassembly. The new design improves the critical task of balancing the telescope and makes the process easier, faster and more secure.

During SOFIA's maintanance visit at Lufthansa Technik in Hamburg, the prototype of the fastening system was tested. The actual flight hardware was installed in the beginning of 2015. The design and project was executed in accordance with NASA regulations and aerospace standards.

SOFIA is an 80/20 partnership of NASA and the German Aerospace Center (DLR), consisting of an extensively modified Boeing 747SP aircraft carrying a reflecting telescope with an effective diameter of 2.5 meters (100 inches). The aircraft is based at NASA's Armstrong Flight Research Center in Palmdale, Calif. The SOFIA Program Office is at NASA Armstrong and is expected to move to NASA Ames at the beginning of Government Fiscal Year 2015. NASA Ames Research Center in Moffett Field, Calif. manages SOFIA's science and mission operations in cooperation with the Universities Space Research Association (USRA; Columbia, Md.) and the German SOFIA Institute (DSI; University of Stuttgart).
