innovative ICE Protection And Shielding System for HLFC Demonstrator

Project description

Resolving space constraints of more-electric aircraft with innovative wiring systems

The aviation industry has made a commitment to revolutionise energy systems on board to reduce the environmental impact of aircraft. In future more-electric aircraft, mechanical, hydraulic and pneumatic systems will be replaced by electrical systems. There are many benefits to this, but the space constraints should also be considered. For example, classic IPS and electromagnetic shielding systems will have to co-exist with the hybrid laminar flow control (HLFC) system in a limited space. The EU-funded ICEPASS project plans to develop a wire harness – assembly of electrical cables – for keeping power and monitoring systems of HLFC organised. Researchers will explore an innovative flat harness concept that could solve the space problem in the leading edge where the HLFC system operates.


Aircraft manufacturers are continuously seeking for decreasing their CO2 emissions and trying to make flights more efficient and eco friendly. As part of this searching one major warhorse is the drag reduction during flight; One of this systems is the Laminar Flow Control LFC, where Hybrid Laminar Flow Control (HLFC) is included. Classic systems as IPS and shielding systems have to coexist with the new HLFC system in a much reduced allocation space.

Towards the new generation of more efficient aircraft the use of More Electric Aircraft (MEA) is increasing during the recent years and modern aircrafts such as Airbus A350 and especially Boeing 787 are mounting more electrical systems.

This project faces two challenges. Firstly to develop an electrical harness for power feed and monitoring systems of the HLFC, and secondly to develop an innovative way of carrying electricity in an aircraft to solve the big problem of lack of space in the leading edge where these HLFC systems operate. Regarding the first challenge IcePass proposal includes a detailed study of the new routings, with selection of components, and application of additive manufacturing tecnologies for brackets, in order to fullfill the complex space requirements of HLFC. For the second challenge IcePass proposes an innovative flat harness concept with application of 3d printing technology which will solve the space problem in the L/E and make possible an HLFC system. Whatismore, IcePass proposes aswell an innovative way of routing harnesses through mechanisms, and particularly for the actuation system, by application of slip rings.

Solving both challenges, IcePass will manage to design and manufacture the electrical system of the HLFC thanks to the application of innovative wiring system concept which will change the state of the art in aerospace industry and manage to achieve the bigger MEA challenge.
