| The objective of ADELINE is to develop new architectures and technologies of air data systems forimplementation in new aircraft on the horizon of 2010. Actual air data equipment is composed of a large number of individual probes and pressure sensors. This equipment delivers vital parameters for the safety of the aircraft's flight such as air speed, angle of attack and altitude. The loss of these data can cause aircraft crashes especially in case of probe icing.The main project targets are:-to reduce present equipment costs by 50 % including purchasing and exploitation costs,-to increase aircraft's safety by drastically reducing air data system failure.These targets will be achieved by developing simpler, more reliable and safer equipment than the American systems that dominate the market. The scientific objectives of ADELINE are:-Identification of innovative air data system architectures.-Development of innovative measuring concepts to acquire all information with only two different types of probes instead of 3 for competitors' solutions.-Development of breakthrough technologies: New probe material and associated nanomaterial coating in order to reduce abrasion and ice adherence. Innovative self regulated anti-icing technology based on the use of positive temperature coefficient (PTC)ceramics. New packaging technologies for MEMS pressure sensor to allow the integration of the sensor within the probe.-Development of a self-test for pressure sensor.To achieve these objectives, a consortium of 8 partners with all the required skills has been established asfollows: 2 SMEs, 1 industrial, 3 academic institutes and 2 research centres.The project is organised in 5 work packages which will allow:-the definition of the system architecture,-the development of innovative principles and technologies,-the development and the flight tests of 2 different functional mock-ups.The duration of the project is 36 months. |
