High stability Altimeter System for Transponders and Air data Computers

Objective

The main project strategic objective is to increase the safety in all in-flight situations, particularly low visibility situations, by improving the transducers used in Air Data Computers (ADC) for aircraft applications. The results are relevant in auto pilot situations in the reduced vertical separation minima legislation of 1000ft, as well as in demanding manual flying situations in darkness and low visibility. Used in transponder applications, the project will give significantly increased reliability in altitude information for manual and automated Air Traffic Control systems. Aircraft Traffic Collision Avoidance Systems will also benefit from more accurate and reliable altitude information, which will allow the automated avoidance instructions to be more accurate and effective. The project will develop a new generation of ADC, suitable for fixed wing and rotary wing applications, which will give altitude accuracy capabilities significantly improved over those available today. Aircraft flight test ing performed in the project will demonstrate the effectiveness of the performance improvement. The transducer long term drift goal is #lt; 0.01 %FS/year. The root causes for long-term drift will be determined by modelling and detailed statistical char acterisation and analysis. Resulting effects of these causes will be minimized by careful co-design of sensor element, fabrication processes, sensor package, and electronics. The end result is a design and fabrication route which is optimised for excellent stability and repeatability. The TTC extension will introduce a ceramic adaptor as part of the sensor package. This adaptor is intended to reduce thermal induced stress on the sensing element coming from the sensor package and its surroundings. A HASTAC target is that European avionic system industry will regain the market lead in ADC as well as in pressure transducers of extreme long-term stability.
