Abstract

The system integration design technologies for achieving low sonic-boom, low aerodynamic drag, low landing and take-off noise, and light weight simultaneously are the key technologies for future supersonic airplanes. JAXA is promoting the R&D for these technologies based on our experiences of demonstrating the advanced low-drag and low-boom design concepts.

Use of the Supercomputer

In the R&D for system integration of silent supersonic airplane technologies, the airplane design study of a small-size civil supersonic transport is conducted. Simulations for evaluating the aerodynamic performance and noise characteristics are conducted using JAXA supercomputer system.

Necessity of the Supercomputer

To achieve low sonic-boom, low aerodynamic drag, low landing and take-off noise, and light weight simultaneously, the multi-objective optimization tools are utilized in the design study. The super computer is necessary to obtain the multiple objective function efficiently with many numerical simulations.

Achievements of the Year

A numerical simulation of the sonic boom prediction of some configuration as a part of 2nd AIAA Sonic Boom Prediction Workshop is conducted in order to improve the numerical accuracy. CFD analysis of the 3 models using JAXA's TAS solver were performed and their results were almost same as the other participant's results.
