摘要

Advanced communications, guidance and navigation systems play key roles in determining superiority of one combat aircraft over another. The use of advanced technology is essential to meeting the mission requirements of present as well as future aircraft. Modular avionics are being used in next generation aircraft, such as the Air Force F-22 fighter and the Army Comanche helicopter, as the means of achieving higher levels of performance, including reduced volume and improved adaptability, maintainability, and expandability. New system acquisitions such as Joint Strike Fighter will attempt to achieve these same performance levels but at dramatically reduced life cycle cost. Retrofit applications will also take on increasing roles in meeting this affordability need as the Department of Defense (DoD) struggles to maintain readiness in the face of the shrinking defense budget. The government is encouraging the use of open standards practices as a means of addressing the affordability issue. The Open Systems Joint Task Force (OS-JTF), formed in September 1994, is chartered to “sponsor and accelerate the adoption of open systems in weapons systems and subsystem electronics to reduce life-cycle costs and facilitate effective weapon system intra- and interoperability”. The purpose of this paper is to relate the concept of open systems to modular avionics. It discusses the key attributes of an open systems approach and identifies key technologies necessary for its success
