| Abstract: |
| There are more faults of the navigation computer system in flight training, and
it is hard to clear them. In order to solve the problems and to meet testing req
uirement of
navigation computer system in overhaul work,a check-up equipment based on indus
trial computer is designed in which 14-bit high precision Revolver-to-
Digital Converter and large-scale digital integrated circuits are adopted.Throu
gh simulati
ng communication signals among airborne devices, the functional faults testing
of the
digital computer, console and code conversion device can be accomplished fast,ac
curately and automatically. The precision of angle simulation reaches 1.3′. |
