Design and development of the objective of the AUDACITY project is to make the demonstration of a compact powerful and reliable piezoelectric actuator for future locking applications in landing gear systems.

Audacity is required to get rid of the well-established hydraulic actuators in order to comply with System ITD Strategic Objectives in terms of environmental impact and More Electric Aircraft (MAE).

One American and one Japanese company have shown the relevance of the piezoelectric technology to be used in landing gear systems. Their demonstrations are today without equivalent in Europe.

Whereas the principle of long stroke piezoelectric actuator is not new, technical challenges occur. The consortium of AUDACITY has concluded every technical limitation one by one during the 20 past years. The technical objective is then to integrate all these individual progresses within a prototype for TRL4 demonstration.

AUDACITY aims at impacting the competitiveness of Europe and Associated countries with the direct creation of 20 jobs and 45 Million of cumulative sales before 2030.
