Smiths Industries to provide analog/digital gateway on Lockheed Martin JSF aircraft

By John Keller

FARNBOROUGH, England -- Avionics designers at Smiths Industries Aerospace are set to build at least four avionics subsystems for the Lockheed Martin entry in the competition to build the future Joint Strike Fighter (JSF).

One of these systems is a software-programmable interface unit that will serve as the JSF's electronic gateway between the aircraft's analog subsystems such as sensors and actuators, and its digital subsystems such as the flight and mission computers.

This gateway device is called the JSF Vehicle Management System Remote input/output Unit -- better known as RIO. Developing this 6-by-6-inch module that is 1.1 inches thick, are designers at the Smiths Aerospace group in Cheltenham, England.

The RIO "does analog to digital conversion, helps flight computers talk to flight actuators, and gives the right amount of power to sensors and other subsystems," says Paul Capener, New product development manager, vehicle management systems at Smiths.

Smiths Industries designers also are providing the Lockheed Martin JSF with its Tactical Data Equipment, Stores Management System Fuselage Remote Interface Unit, and with Hamilton-Sundstrand is providing the Lockheed Martin JSF with its Electrical Power System.
