The reliability of the software running in airborne vehicles (civil or military) is shown by the fact that most airborne accidents occur due to manual errors. Unfortunately reliable software is not necessarily easy to use or intuitive, poor user interface design has been a contributing cause of many aerospace accidents and deaths. [citation needed]
Predecessors to OpenVSP including VSP [1] and Rapid Aircraft Modeler (RAM) were developed by J.R. Gloudemans and others [2] for NASA beginning in the early 1990s. [3] OpenVSP v2.0 was released as open source under the NOSA license in January 2012.
Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.
Engineers worked directly with computers in generating 3D models of the aircraft, and took advantage of the design software in facilitating machine-tool preparation. The system consisted of 15GB databases of each of the Rafale's components, assisting with various aspects of the design, manufacture and through-life support. [44]
Dassault Systèmes SE (French pronunciation: [daso sistÉ›m]) (abbreviated 3DS) is a French multinational software corporation which develops software for 3D product design, simulation, manufacturing and other 3D related products. Founded in 1981, it is headquartered in Vélizy-Villacoublay, France, and has 23,811 employees across 194 global ...
The company developed its own aircraft design software, Advanced Aircraft Analysis (AAA), as well as a second design program for a NASA Small Business Innovative Research contract. [5] In 2002 he published Roskam's Airplane War Stories a collection of stories about airplane design and analysis and engineering mistakes that were made. Many of ...
DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a guideline dealing with the safety of safety-critical software used in certain airborne systems. It was jointly developed by the safety-critical working group RTCA SC-167 of the Radio Technical Commission for Aeronautics (RTCA) and WG-12 of the European ...
No Effect - Failure has no impact on safety, aircraft operation, or crew workload. DO-178C alone is not intended to guarantee software safety aspects. Safety attributes in the design and as implemented as functionality must receive additional mandatory system safety tasks to drive and show objective evidence of meeting explicit safety requirements.
