Obiettivo
The aim of the NESLIE project is to develop a 3 axis laser function for air data standby channel for implementation on civil aircraft on the horizon 2010. Actual air data standby channel is composed of individual probes and pressure sensors. Air data standby channels information delivers vital parameters for the safety of the aircraft's flight such as air speed, angle of attack and altitude. But since primary and standby channels have similar failure modes, the use of laser based standby architecture with drastically different failure modes must increase aircraft's safety by reducing the probability of common failures. This technology will also allow to have a nonprotruding probe to measure air speed, angle of attack and slide slip angle in comparaison to traditional probes which have protruding parts subjected to external agressions. NESLIE project main achievements will be : - The design of a Lidar based air data standby system optimized in term of size and weight, allowing at least true air speed (TAS), angle of attack (AOA) and side-slip angle (SSA) measurements. The laser detection range being quite short, from 10 to 100 cm. - The use of guided optics technology (integration on substrate) so as to guarantee compactness and cost reduction. - The design and manufacture of needed technological bricks (ie. separator, commutation, pumps hybridization, low noise detector, low noise power supply) and merge into a minimal number of modules. - A system analysis and definition of sub-systems to be integrated in a standby instrument. - The design and optimisation of an adapted signal processing. - Tests.
