LOW-SONIC-BOOM CONCEPT DEMONSTRATION IN SILENT SUPERSONIC RESEARCH PROGRAM AT JAXA

Makino, Yoshikazu;

Full Article:

JAXA’s supersonic research program named S-cube for future supersonic airliners with economically viable and environmentally friendly characteristics and the flight test pro-ject named D-SEND for demonstrating the advanced low-boom design concepts are intro-duced. In the first phase of the project(D-SEND#1), two axisymmetrical models were dropped back to back from a stratospheric balloon and the sonic-booms generated from both models were measured both on the ground and at about 1km above the ground in order to validate JAXA’s sonic-boom measurement system and to make sure the possibility of demonstrating low-boom concepts with the 8m-long scaled model in the second phase of the project(D-SEND#2). The D-SEND#2 airplane is an unmanned low-boom scaled airplane which is con-sidered to be a 16% scale model of a 50-passenger small size supersonic transport regarded as a technology reference aircraft of the S-cube program. Some low-boom design concepts such as a non-axisymmetrical low-boom nose, a low-drag/low-boom wing geometry, a lifting aft-fuselage, and reverse-cambered horizontal tails which are applied to the D-SEND#2 air-plane will be demonstrated in the drop test.
