New alloys in heat exchangers

Wolverhampton-based company, HS Marston Aerospace – part of US company Hamilton Sundstrand Engine & Control Systems - has worked with Telford SME Advanced Chemical Etchings to develop high temperature heat exchangers for aircraft engines made from new alloys. Hi-temp capability is a significant contributor to fuel-burn efficiency, and the ability to operate at higher temperatures can result in CO2 reductions of up to 10 per cent. Tests completed by the company show that the new alloy heat exchanger can operate at up to 300C hotter than existing units. These results have led to HS Marston Aerospace becoming one of 10 partners on the Environmentally Friendly Programme (EFE) launched by Rolls-Royce to develop greener engine technology for the future. Launched in 2006, EFE is addressing engine technologies to cut nitrous oxide emissions by 60 per cent, among other benefits.
