Call for proposal
Link to CORDIS

IN-LHC (€33M turnover, 260 persons staff), belongs to Zodiac Aerospace Group. Zodiac Aerospace is quoted on the French Stock Exchange and has focused activities in aerospace industry. IN-LHC’sole facility gathers in Châteaudun, France, all the skills to design, manufacture, test and support EHSV and other complex hydraulic control equipment. This location is the sole one to which we will refer in this proposal, meaning that all studies and manufacturing will be held within European community. IN-LHC core business lies in supports equipment and sub-systems for hydraulic and fuel servo control systems and therefore, the engineering department takes a central position in its strategy. Through SAGE Call 12th project, IN-LHC’s aim is to contribute to European new knowledge and technology development.

IN-LHC has proven experience in the development of different equipment for programs like the Airbus, Falcon or CRJ families for the aircrafts and the CFM56, Arriel and Makila families for the engines. Recent achievements include servovalves for the A380 and A400M, landing gear hydraulic manifolds for Falcon 7X and Superjet 100. In the engine control applications IN-LHC Zodiac Aerospace supplied servovalves not only for French engines like M53, M88 or Makila but also for European cooperations like RTM322 or TP400 and for international programs like Kaveri or SaM 146.

In this call context, IN-LHC Zodiac Aerospace can compare the Open Rotor 12th Call project to previous ones developed for brand new aircraft/engines. As a matter of fact, IN-LHC Zodiac Aerospace structure can deal with this kind of demanding development in terms of engineering and industrial means.

For this call, IN-LHC’s overall strategy derivated from the dual objective which combined a short path development for the demonstrator SV and a long path development for the target engine. Lastly, a work package was fully dedicated to the test bench project.

Executive Summary:

The SAGE2 Demonstration Project aimed at designing, manufacturing and testing a Counter-Rotating Open Rotor (CROR) Demonstrator. It involved most of the best European Engine and Engine Modules and Subsystems Manufacturers. The CROR engine architecture was a challenge for the Pitch Actuation System and especially the performance requirements associated to high flow levels to actuate the blades pitch.

Zodiac Hydraulics was selected to design, to manufacture and test servovalves needed by Pitch Actuation System architecture.
