Welcome to Obayashi, Yakeno Lab.!

ABOUT US

We are working on experimental fluid dynamics, computational fluid dynamics, and their integration for the innovation, safety, and creation of aerospace systems.

  • Innovative design and manufacturing assisted by "Computational Fluid Dynamics", “Multi-Objective Design Exploration” and “Uncertainty Quantification”
  • Innovative engineering design driven by “Data Assimilation”
  • Innovative aerospace plane experimented by “Magnetic Suspension and Balance System” and “Ballistic Range”
