68 | Cluster Report I Transport, Mobility and Logistics – Aerospace Deflectometry Optical measurement solutions and illumination systems Demanding requirements for materials and their surfaces exist in a wide range of fields, such as the aviation or automotive industries, but the data/ know-how/information regarding how ma terials change over time when in use (their “life cycle”) are crucial factors for functionality. 5micron GmbH is a young company, which has been located in Berlin-Adlershof since January 2015. The 7 team members develop optical measuring methods and systems, and currently focuses mainly on unusual fields of application for: • Highly precise measurements on large or faraway objects • Geometric measurement of inaccessible surfaces • Geometric measurements in harsh environments • Deflectometry (geometric measurements of dimensions such as length, torsion, roughness etc.). Resolution: 50 µm • Shadow casting (defects inspection (OK/NOK decisions)). Resolution: 20 µm • Pattern projection (analysis of surface structure/topography). Resolution: 5 µm One example of a system solution is the measurement of the wing surfaces of an aircraft during flight, in particular the monitoring of changes for shape, dimensions and material defects with a precision of a few micrometres. One other example of a miniaturized measurement system was developed for an engine manufacturer in which measurement technology for the minimally invasive inspection of engines with the use of an endoscope was developed, with a resolution of 5 µm. Services • Measurement system solutions for the following applications: High speed data acquisition and image analysis (optimised algorithms); Contactless in the form of a mobile or stationary measurement system (also miniaturised/for adverse lighting conditions where necessary); Online evaluation can be used on a wide range of surfaces and materials/hardened sensory equipment and hardware for adverse environmental conditions • Special illumination systems • Communication via light pulses (V2X; IoT) Contact 5micron GmbH’s current portfolio is made up of two business segments: 1. Surface measurement technology, and 2. Special illumination systems. The business segment surface measurement technology is concerned primarily with development projects for the aviation industry, which are based on optical methods. The methods are: In the business segment special illumination systems, the feasibility of data transmission via pulses of light was demonstrated as part of an internal project. This enables communication and interaction between any kind of object or vehicle. Particularly in automatically and autonomously driven vehicles in road traffic, it is crucial that the networks between vehicles as well as the infrastructure are resilient (V2X). 5micron GmbH Rudower Chaussee 29, 12489 Berlin +49 30 565908850

Cluster Report I Transport, Mobility and Logistics – Aerospace | 69 MICROJET 2000: Modular Propulsion System for Satellites AI: Aerospace Innovation GmbH Range of Products and Services Services • Development, manufacturing and qualification of demonstrators, prototypes, and products of customised propulsion solutions for terrestrial and orbital operation AI: Aerospace Innovation GmbH in Berlin develops special high-technology solutions and applications for the national and European aerospace industry and related agencies – DLR and ESA. Due to a long-standing experience in research and education along with extensive and detailed experimental work, the company is characterised by a unique technical know-how in the area of development, qualification and operation of aerospace systems. AI: Aerospace Innovation was launched in 2007 as an evolution of the AI: Aerospace Institute that was founded in May 2000 within the frame of the Technology Transfer Program at Berlin University of Technology (TU Berlin). The company presently focuses on development, qualification and manufacturing of customised propulsion solutions (e.g. MICROJET and AQUAJET propulsion systems) for terrestrial and orbital operation. The range of products includes launch vehicle and propulsion subsystem and system engineering, feasibility investigations for new technologies and systems including development and manufacturing of demonstrators and prototypes, numerical simulations of complex dynamic processes, e.g. combustion in solid and hybrid rocket motors, feasibility investigations for new technologies and systems as well as system, trend and cost analyses. • CAD- and FEM-based engineering according to ISO/ECSS • Numerical simulations of complex dynamic processes, e.g. combustion in solid and hybrid rocket motors • System, trend and cost analyses MICROJET 2000 Propulsion System Implementation on BIROS Satellite (image credit: DLR) The focus of AI: Aerospace Innovation activities are placed to environmentally friendly and costeffective satellite and rocket propulsion systems for earth and orbital applications. Currently, electrothermal, cold gas, solid and hybrid propulsion systems are under development. Until now, the team of AI: Aerospace Innovation has developed, qualified and successfully operated more than twenty-five propulsion systems for various terrestrial and aerospace applications.
