¡nApplication of the 3D Software Wreckage Reconstruction Technology at the Aircraft Accident Investigation
The purpose of this paper is to present a methodology and application of a
Three-Dimensional-Software-Reconstruction and Presentation System (3D-SWRPS).
This system was developed to support the investigation of China Airlines flight CI611 in flight breakup accident that occurred on May 25, 2002. The accident aircraft was a B747-200 carrying 19 crewmembers and 206 passengers. The accident occurred near Penghu Island in the Taiwan Strait. All 225 people onboard the aircraft perished in this accident.
The Aviation Safety Council, an independent government organization responsible for all civil aircraft accident and serious incident investigation, has been investigating the accident. At the moment of this writing, this investigation is still ongoing and probable causes of this accident have not yet been determined.
The 3D-SWRPS utilizes a combination of the computer 3D-graphic techniques,
laser scanning of wreckages recovered, structure frame of a Boeing 747-200 cargo aircraft, and a generic CATIA engineering model of the same type of aircraft. It can provide sub-centimeter accuracy in the reconstruction process, and can be used to determine fracture behavior and propagation of stress of break up. In addition, the 3D-SWRPS can combine radar return signal, wreckage salvage data, and ballistic simulation program to assist in the analysis of breakup sequence. It is believed that this technology would play an important role in supporting future accident investigation.
