| Abstract Scope |
Combustion in rotating detonation engines (RDEs) generates rhythmic vibrations in the kilohertz range and reaches combustion temperatures exceeding 1800 °C. Due to this high-temperature environment, ceramic materials are preferred for internal structural components in RDEs. This study focuses on designing glass/ceramic composites capable of absorbing part of the detonation energy by tuning the glass transition temperature of the glass phase to align with the operational temperature and frequency of RDEs. Results will be presented for a model system consisting of amorphous silica (SiO₂) within a mullite (3SiO₂–2Al₂O₃) matrix, where silica serves as the tailorable energy-absorbing phase and mullite is the elastic matrix. The influence of microstructure on damping behavior as a function of temperature will be discussed, along with an evaluation of digital light projection as a potential additive manufacturing method for fabricating RDE components. |
