Together with Sonaca Calyos will develop a novel heat exchange technology to de-ice the nacelle.
Together with Sonaca and RTA, Calyos has secured EU Horizon 2020 funding to develop a novel heat exchanger for engine oil systems, recovering the heat to de-ice the nacelle.
Project Description
An airplane comprises the fuselage – the main body of an airplane, wings, tail, engines and other parts. The nacelle is the smooth cover that houses a jet engine. This aerodynamic shell minimises drag and also reduces noise and serves a de-icing function. Since the 1970s, nacelles made from composites have decreased the weight, noise, and emissions associated with engine function. Now BISANCE is making green greener with an autonomous biphasic system to simultaneously cool engine oil and provide ice protection. Heat from the engine oil will be used to de-ice the nacelle. Even better, the new system will significantly decrease the weight, CO2 emissions, and lifetime operating costs of a turboprop aircraft.
Coordinator: Sonaca
Other Participants: Rail Tec Arsenal (RTA)
Project Objectives
BISANCE intends at defining a biphasic system integrated into a full composite nacelle and engine air intake. The biphasic system aims at decreasing significantly the weight, the environmental footprint as well as the space allocated by the current active systems for the cooling of the engine oil and for the energy supply of th ice protection systems. These both active systems (needing external power) will be replaced by a biphasic passive system (autonomous with no need of external power) which will extract the energy from the engine oil and transfer it to the ice protected surfaces. The objective of the project is thus to decrease the weight by 25kg for the two nacelles of a turboprop A/C, to decrease the CO2 emissions by almost 900 000 kg per AC life and to save 200 000$ of operating costs per AC life. The project will be divided into 5 work packages along 30 months. The first step intends at defining the specifications and the requirements of the product. Based on the requirements, several concepts of system integration into the structure will be proposed and manufactured for selecting the most promising one. Qualification tests are expected for characterizing the structural resistance and stiffness of the concept, for verifying the resistance to heat cycles and to impacts. Finally a full scale demonstrator will be manufactured for testing it in icing Wind tunnel. The project will be coordinated by Sonaca, also in charge of the structural developments, in association with Calyos, in charge of the system developments and with RTA in charge of performing the icing wind tunnel testing.

EU Project PageWhat
Calyos is one of the world's leading experts in two-phase (liquid to vapour) heat transfer technologies. Calyos has developed a number of solutions for three specific cooling applications; power electronics, processors and batteries. Calyos also develops custom solutions beyond those applications for example, engine oil heat recovery. Calyos primarily targets the E-Mobility and Computing markets, where electrification and data processing are creating ever-rising demand for new, disruptive thermal solutions.
When
Calyos was incorporated in 2014 and is a spin-off from Euro Heat Pipes (EHP) who successfully developed similar two-phase technology for the space industry. EHP was incorporated in 2001 and today holds a majority market share in the European satellite market. Airbus D&S is now the majority shareholder in EHP. Calyos has been developing the technology for ground applications. This has involved a considerable amount of research and development, including developing flat evaporators, switching the working fluid to a dielectric green refrigerant and working on real-world applications such as those mentioned above.
Where
Calyos is based in Charleroi, Belgium. Calyos operates a factory side-by-side with our engineering team at this location and currently all of Calyos' production comes from this factory. Calyos supplies its products all across the world, including Asia, North America, Europe and South America.
Who
At Calyos we are a diverse group of talented individuals galvanised by the pursuit of establishing our disruptive, sustainable technology in our target markets. Remaining curious enables continued innovation as we work together to achieve our mission.
How
Calyos is built around four core values:
1. Applied Knowledge: Our technology is worthless unless we can get in it out there in the market. We strive to apply our knowledge and experience to real world applications.
2. Better Together: We succeed together. We view everyone from our customers to our shareholders as part of our team. Without working together we are nothing.
3. Inherent Flexibility: No thermal problem is the same. Therefore we strive to build flexibility into not only our solutions but also our working practices. This allows us to evolve with the market.
4. R-R-Research: Nothing stands still. As experts in our field, we must continue to innovate. We can then return to our first point and re-apply these innovations to real world applications.
Why
Our mission is to solve the greatest thermal challenges by enabling the adoption of the best, passive two-phase cooling solutions. Ensuring and delivering a sustainable approach to thermal management in the data-driven and electrified world we are creating.
