Nederlands Lucht- en Ruimtevaartcentrum

The National Aerospace Laboratory (NLR) is the central institute for aerospace research in the Netherlands. NLR is an independent non-profit organisation that provides technological support to aerospace industries, to operators of civil and military aircraft, to airports and ATC systems, to authorities and to international organisations, all over the world.
NLR has three main divisions: Air Transport, Aerospace Systems & Applications, and Aerospace Vehicles. NLR has two sites and highly trained staff of about 700 people. NLR has a number of specialised RTD&E facilities, e.g. for flight-simulation, avionics, EMC and environmental testing, aerodynamic, structural testing, and manufacturing of high performance composite structures. NLR’s Aerospace Vehicles division has extensive expertise in many areas of aerospace technology, in particular in multi-objective optimisation of aeronautic systems, multi-disciplinary design and structural analysis, and in thermal system design for aeronautic and space application

Role in the project

NLR leads the developments in WP3, IPPS system optimisation, with focus on a space allocation optimisation methodology for UHBR engine equipment.
Moreover, innovative cooling solutions will be developed for engine equipment cooling in WP2 and the development of engine harness test facility in WP3.
NLR has extensive expertise, supported by various research facilities, in modelling, design, optimisation and testing of aeronautic and space systems. Besides specific knowledge in the areas of aero-engines and gas turbines, also experience on system level is available for example from research projects on optimisation of power consumption on aircraft level or for example looking at more electric aircraft architectures. Very broad experience exists in the area of optimisation, both in the application of state-of-the-art methods for example in multi-disciplinary design studies, as well as development of in-house methods and tools for surrogate modelling and multi-objective optimisation. In the area of thermal modelling and cooling systems, NLR has gained experience in design and development of Mechanically Pumped Loops (MPFL, AMS) (i.e. heat transport systems) in space and in semiconductor industry. NLR has led an international co-operation for the development of the Tracker Thermal Control System (TTCS) now flying on the truss of the ISS (

Dr.Ir. Henk Jan van Gerner
Henk Jan van Gerner is a research Engineer at the thermal department of the NLR. He has extensive experience in the design and development of advanced two-phase cooling systems for both terrestrial and space applications. His current work is focused on the development of novel lightweight systems (e.g. vapour-compression cycles), transient numerical modeling of two-phase cooling systems, and systems with very accurate temperature control (0.001°C accuracy). Henk Jan studied mechanical engineering and obtained a PhD in the Physics of Fluids group at Twente University in the Netherlands.
