Aero engine running is complex mechanical experiments. In the last two decades, many computer aided testing (CAT) systems were developed and employed in aero engine running. Traditionally, the main role of a CAT system is data acquisition, which developed with the client/server (C/S) architecture. Now, a CAT system plays more and more important roles in information management, such as measurement channels management, experiment design and management, data analysis and report management, and so on. Users may work on local place or on remote. So, it is not only a data acquisition system, but also an information system. In this paper, we introduce hybrid architecture of C/S and browser/server (B/S) to take advantages of both of them. For local users, clients are realized to provide local monitor and operation. For remote users, browsers provide not only real-time measurement data, but also querying and management of the history data. It demonstrates that the CAT system meets the requirement of aero engine running.
