A New Data Distribution System for Aircraft.
Abstract
During a mission, a large number of avionic signals are transferred within a military aircraft. Data separation and routing, heretofore usually have been achieved by running a dedicated wire, point-to-point, for each signal. This is costly in terms of cable weight, reliability, growth flexibility and maintainability. The author proposes a new information distribution system in which the signals are simultaneously encoded in the frequency, space and time domains. This approach, called three dimensional orthogonal code division multiplexing, is contrasted with conventional time division multiplexing. Potential advantages of the former are pointed out. The report describes the basic concepts in general terms, then presents the application of one version of the design to the night A-X aircraft. It is concluded that the (Rusmux) approach offers considerable promise for solving the complex information management and distribution problems encountered in the design of modern aircraft. It is recommended that resources be allocated such that the concept, by simulation and hardware fabrication, can be verified experimentally in the laboratory. (Author)
