Non-Defence Trials

Super-Sonic Transport Trials

Following the success of the ALFLEX program, JAXA selected Woomera for the conduct of the National Experimental Supersonic Transport (NEXST) flight trials. The NEXST program involved the rocket-boosted launch of a one tenth scale model unpowered supersonic airplane. The purpose of the trials was to verify the aerodynamic design of a next generation supersonic airliner based on theoretical modelling and wind tunnel testing in Japan.

JAXA undertook significant infrastructure upgrades at the WTF in preparation for the NEXST flights including the installation of a heavy duty launcher and associated air-conditioned moveable shelter, commissioning of a 100 kW radar Upper-Air Wind Profiler and also improvements to various range facilities.

The first NEXST flight on 14 July 2002 failed due to premature separation of the airplane from the booster. The second flight on 10 October 2005 was spectacularly successful (pictured). Following launch and separation from the booster, the airplane reached an altitude of 19 km and travelled ~100 km down-range at a speed exceeding Mach 2. After completing the aerodynamic measurement phase, the airplane returned autonomously for a perfect parachute and airbag landing approximately 15 km from the launch site. Images and video of the flight are available at JAXA’s Aviation Program Group website. Extensive support of the NEXST program was provided by AOSG and Adelaide-based aerospace companies.

The Aviation Program Group of JAXA is currently progressing plans for follow-on flight testing of a powered supersonic airplane known as the Silent Super-Sonic Technology Demonstrator (S3TD).
