Inclined heat exchanger
Offering reduced system weight and size as well as improved aerodynamics, leading to improved engine efficiency and reduced fuel burn.
Our advanced thermal systems technology is making a significant contribution to the industry-wide goal of reducingCO2 emissions. The unique design acts as an enabler for the introduction of the new power gearboxes and slim-line nacelles that are at the center of engine manufacturers’ efforts to deliver a significant improvement in specific fuel consumption for the next generation of engines.
To accommodate the new fan and gearbox design, our customers need to slim down the nacelle, compromising the available space for equipment traditionally housed in the nacelle mounted off the engine fan case.
This radical engine design presents significant challenges for thermal systems, as the new power gearbox doubles the heat load to the oil that our heat exchangers cool. In addition, the slim-line nacelle means that our thermal systems now need to be mounted on the core case, a more spatially constrained part of the engine. Our patented inclined heat exchanger system in this application is showing >40% performance improvement over datums. The system’s 0.3% reduction in fuel burn amounts to a yearly reduction of 200 tons of CO2emissions per aircraft.

Outlet guide vane (OGV) oil cooler structural heat exchanger
Integrating the thermal management solution into an existing structure on agas turbine engine, the OGV oil cooler provides higher efficiencies and lower weight in challenging tight spaces.
Jointly developed with GKN Aerospace, the OGV oil cooler isa Macrolaminate™ heat exchanger that offers optimal heat transfer when space is at a premium and weight and drag must be minimized. The product integrates the thermal management solution into an existing structure on the gas turbine engine.
Fabricated using the Macrolamination™ process to attain superior mechanical and thermal properties, these heat exchangers can achieve a high level of load-bearing capability and enable advanced engine architectures, while increasing heat sink, limiting weight and drag impact, and conforming to present envelopes.

Advanced Macrolaminate™ liquid cold plates
Delivering focused cooling in small envelopes, these devices are strong and lightweight, an efficient package for managing high heat in harsh environments.
Macrolaminate™ liquid cold plates enable extremely high-power densities, providing focused cooling in envelopes as small as 1/8-inch thick.
Offering thermal performance far exceeding traditional designs, they can be flat or designed to conform to a shape, and can also double as mounts, enclosures or EMI/RFI shielding.
Ruggedly constructed for harsh environments, Macrolaminate™ liquid cold plates manage high heat flux in an efficient package. Employing a multilayer fluid passage design and thin, lightweight construction, these devices are optimized for SWAP and deliver excellent thermal performance in both single- and two-phase applications.
