This presentation will summarize the current VTOL Turbine Power Research at CCDC Army Research Laboratory. ARL is developing disruptive advanced materials and turbomachinery concepts / technologies for highly improved power-density, durability and efficiency for the Army of 2035+ VTOL gas turbine propulsion systems that address power demand, speed, range and low-cost sustainment gaps.
The objective of this research is discovery and operationalization of advanced material systems, multi-physics high-fidelity computational methods and advanced turbomachinery concepts for future Army VTOL propulsion. It is operationalizing VTOL Turbine Power Science for technology overmatch of US military. This will lead to improved power-density, durability, and high-efficiency technologies for transition to Army VTOL propulsion.
The main research thrust areas are:
- Advanced Ceramic Composite Systems
- Ultra High Temperature Ceramics for Propulsion
- Advanced Thermo-Fluid Models in Pressure Gain Combustor Environments
- Advanced Gas Generator Turbine Concepts
The metrics for the research are (a) durable turbine material system will provide 30% increased life; (b) Next-generation ultra-high temperature ceramics enabling 50% improved efficiency/power-density; (c) High-fidelity computational methods for predictive designs of novel turbomachinery concepts; (d) Advanced turbomachinery concepts, material systems, and turbine configurations enabling 50% improved efficiency/power-density and 30% improved durability.
The knowledge products of this research are:
- Increased knowledge of processing-structure-property (PSP) relationships for technical/refractory ceramics, ultra-high temperature ceramics (UHTCs), and hybrid materials exposed to extreme conditions.
- Advanced low-k refractory ceramic materials, with high fracture toughness and attrition-resistance
- High-accuracy fluid-structure interaction models in multiphase turbulent internal flows with low computational-cost
- Advanced turbomachinery concepts and designs enabling responsive propulsion systems with high power density.
