Reasons for using JSS2
Simulation environment is arranged well. And also, CFD software is substantial.
Achievements of the Year
CFD simulations have been carried out using “Fluent”.
In order to confirm the validity of CFD, CFD simulation was performed on the shape of which wind tunnel experiment was performed and the results were compared. A consistent result was obtained for lift and drag. (fig.1)
We are considering to apply the concept of wave rider to the aerodynamic shape of space planes. In wave rider, we considered improvement of performance at non-design Mach number by changing aerodynamic shape, and evaluated its effect and characteristics by CFD. By bending the tip of the wing to approach the shock wave surface, we considered to improve the performance below the design Mach number, however the performance did not change very much. While, it showed that the performance can be improved at above design Mach number by contracting the wings. (fig.2)
