With faster processors, more functions, and higher bandwidth than ever before, today’s avionics are pushing the cooling technology envelope to the breaking point – and beyond.

New commercial and military aircraft production is preceded by extensive flight tests to prove the performance of the aircraft and its sub-systems.

Modern aircraft flight test instrumentation system design revolves around defining the most efficient method to collect aircraft data for both on board recording and real-time telemetry transmission.

Test and measurement equipment for the flightline is becoming smaller, lighter in weight, less power-hungry, and requires fewer maintenance personnel than ever before.

Until recently, the use of moving liquid to remove excess heat from embedded computing processors was considered an expensive and unreliable luxury, but escalating demand and maturing technologies finally are putting this technology within reach.

The company’s Aerospace Instrumentation group presented its system-level flight test instrumentation (FTI) to hundreds of delegates at this year’s show.

As aircraft embedded systems grow in complexity and the aviation industry embraces hybrid electric power, new methods of cooling are emerging to resolve thermal management and overheating challenges.

Ivan Straznicky explains how liquid cooling is becoming more efficient and affordable to give systems designers a leg-up in the battle against electronics heat.
