The Mechanical Components Branch formulates, conducts, and manages research focused on propulsion systems for present and advanced aeronautics and space vehicles. Basic research is performed on mechanical components and systems, including gears and bearings, turbine seals, structural and thermal barrier seals, and space mechanisms.
Researchers in the branch conduct experimental and analytical research to develop the technology to enable the design of low noise, ultra safe drive systems for rotorcraft and conventional aircraft with geared fan drive propulsors. Analytical models for gear crack propagation, gear dynamics and noise, gear diagnostics, bearing dynamics, and thermal analysis of gear systems are developed and validated using experimental data from various component test rigs.
Advanced turbine seal concepts are also developed and experimentally tested to increase efficiency and durability of turbine engines. In addition, experimental and analytical research is performed to develop advanced thermal barrier seals and structural seals for current and next generation space vehicles.
In space mechanisms, fundamental research is conducted on advanced lubricants and materials for mechanical components and mechanisms subjected to deep space and planetary environments.
