Experiments for Collection and Characterization of Particles Exiting from Solid Propellant Rocket Nozzles

Autor: Stefania Carlotti, Niklas Wingborg, Mattias Liljedahl, Tobias Langener, Filippo Maggi, Jeroen Van den Eynde, Dominik Saile, Ali Guelhan

Metals in solid propellants are used to improve specific impulse and increment the energy density. Their combustion generates condensed products that move along the motor chamber and are expelled through the nozzle. The discharge of liquid or solid p

Atmospheric reentry transition is produced at hypersonic velocity and is accompanied by a sharp excessive heat load for a few minutes, on the exposed materials, leading to a temperature increase of more than 1000°C. MPBC developed optical fiber sens

Axisymmetric SCRamjet Engine Design and Performance Analysis

Autor: Johannes C. Riehmer, Ali Guelhan, Andreas K. Flock

In the present work, we treat the SCRamjet engine as a system, by coupling different analytical design tools. For the intake portion a Busemann tool was used, the combustion chamber was modeled with a one dimensional reactor, and the nozzle was model
