Research Group Combustion and Pyrotechnics

In the field of combustion and pyrotechnics, the research focuses on the application of explosives – ranging from characterization and qualification through modeling and simulation to system development.

Modelling and Simulation

Modeling and simulation aim to understand the behavior of the energy systems under investigation through a simplified chemical-physical description and to make predictions based on this understanding. This leads to a deeper understanding of the system and the ability to adapt it for specific applications.

Furthermore, specialized evaluation models support the experimental work involved in qualification and characterization, thereby making physical quantities that cannot be measured directly accessible. This opens up new possibilities for system description and characterization.

Our core areas of work include the characterization of conversion and performance properties, as well as safety investigations of propellants, explosives, and related systems. In addition to standardized tests, we develop and implement test setups and measurement techniques tailored to specific research questions in close collaboration with our customers. Furthermore, we offer all analytical methods necessary for the characterization of energetic materials.

Range of services

  • Spectroscopy of combustion processes, temperature measurement, and species identification
  • High-speed camera systems
  • Analytical measurement techniques for density, thermal conductivity, heat capacity, decomposition kinetics, and oxidation kinetics
  • Reaction monitoring and quality management of energetic materials

Energetic system components

Results from fundamental characterization, modeling, and simulation form the basis for the application-specific design, sizing, and manufacturing of energy systems and system components. The performance characterization of the systems is carried out using sophisticated measurement methods, either based on standard tests or customer-specific tests.
