Research & Development
JAXA promotes three research and development programs and a fundamental research program that underpins them.
JAXA is developing a numerical simulation tool called FaSTAR-Move, an extended version of the fast unstructured-grid flow solver FaSTAR.
FaSTAR-Move employs overset grid method to analyze airflow around moving/deforming objects. By topping up new functions as modules, its simulation capability can be extended depending on users’ analysis needs.
So far, we have released version 1.0 featuring a “moving/deforming object analysis module” to enable simulations such as payload separation and structural interaction. In version 2.0, “rotorcraft analysis module” released to enable simulations around rotorcraft such as helicopter.
In version 3.0 and subsequent releases, we plan to add the engine analysis modules and multi-component gas flow analysis to make further enhancements.
External payload separation analysis
Aeroelastic simulation module
By enabling coupled analysis of fluid-structure interaction, the aeroelastic simulation module enables simulation of flutter phenomena (such as fluttering of wings and airframe) caused by aeroelastic instability.

Rotary wing simulation module
This module is equipped with a function for setting pitch angle control, trim, and other conditions for the rotary wing of helicopters, etc., to enable simulation of blade (single rotating wing) rotation.

Engine analysis module
Engine analysis module enables coupled analysis of thermal interaction of the rotating blade rows (multiple blades lined along a circumference) of aircraft engine fans, compressors, and turbines.

Multi-component gas flow simulation module
This module enables simulation of high-temperature engine exhaust with its extended function to analyze multi-component gas flows.
