Special Issue Information

Dear Colleagues,

It is our pleasure to invite you to submit your scientific contributions to this Special Issue, titled “New Sensors for Metrology for Aerospace”.

The use of sensors and transducers in the aerospace field is continually growing. The purpose of aerospace sensors is to provide all necessary information on the variables and the parameters of the flight system for the execution of a mission.

A modern aircraft is equipped with hundreds of sensors at all levels of the flight system. Thus, they have become an integral part of any flight system, also in preflight operations for maintenance and safety. For example, in case of unmanned aerial systems (UASs), sensors and multi-sensor systems have a crucial role during preflight and flight operations.

This Special Issue aims to highlight advances in the development, testing, and modeling of sensors and multi-sensors system for aerospace. Topics include, but are not limited to:

  • Electronic instrumentation for aerospace;
  • Automatic test equipment for aerospace;
  • Sensors and sensor systems for aerospace applications;
  • Wireless sensor networks in aerospace;
  • Attitude and heading reference systems;
  • Monitoring systems in aerospace;
  • Metrology for navigation and precise positioning;
  • Sensors and Data Fusion Techniques for Avionics and Air Traffic Management;
  • Flight Testing Instrumentation and Flight Test Techniques.

This Special Issue cooperate with "The 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace)", held in Rome, Italy, 20–22 June 2018. Authors of papers presented at this conference and within the scope of Sensors may submit a technically extended version to this Special Issue.

A cross-capacitance liquid level sensor is based on the principle of cross capacitance. This study designed a new single-tube cross-capacitance fuel-level sensor. The fuel-level measurement model is established for a single-tube cross-capacitive sensor, and the relationship between the measured liquid level and sensor output capacitance is derived. The characteristics of the sensor were tested experimentally. The experimental results demonstrate that the linearity error of the liquid-level sensor of the single-tube calculation for the spacecraft is ±0.48%, the repeatability error is ±0.47%, and the hysteresis error is ±0.68%. The cross-capacitive fuel-level sensor developed in this study can be used in the fuel tank of spacecrafts owing to its low weight and high precision. Full article

This paper focuses on the development of a new logistic approach based on reliability and maintenance assessment, with the final aim of establishing a more efficient interval for the maintenance activities for Unmanned Aerial Vehicles (UAV). In the first part, we develop an architectural philosophy to obtain a more detailed reliability evaluation; then, we study the intrinsic reliability at the design stage in order to avoid severe critical issues in the UAV. In the second part, we compare different maintenance philosophies for UAVs and develop the concepts of preventive and corrective maintenance that consider the system subjected (until real “hard failure”) to partial performance degradation (“soft failure”). Finally, by evaluation of the uncertainty through the confidence interval, we determine the new soft failure limits, taking into account the general knowledge of the systems and subsystems in order to guarantee the proper preventive maintenance interval.

An engineering validation of a large optical telescope consists of executing major performing tests at the subsystem level to verify the overall engineering performance of the observatory. Thus, the relative pointing error verification of the telescope mount assembly subsystem is of special interest to guarantee the absolute pointing performance of the large synoptic survey telescope. This paper presents a new verification method for the relative pointing error assessment of the telescope mount assembly, based on laser tracker technology and several fiducial points fixed to the floor. Monte-Carlo-based simulation results show that the presented methodology is fit for purpose, even if floor movement occurs due to temperature variation during the measurement acquisition process. A further research about laser tracker technology integration into the telescope structure may suggest that such laser tracker technology could be permanently installed in the telescope in order to provide an active alignment system that aims to detect and correct possible misalignment between mirrors or to provide the required mirror positioning verification accuracy after maintenance activities. The obtained results show that two on-board laser tracker systems combined with eight measurement targets could result in measurement uncertainties that are better than 1 arcsec, which would provide a reliable built-in metrology tool for large telescopes.

Wall shear stress is an important quantity in fluid mechanics, but its measurement is a challenging task. An approach to measure wall shear stress vector distribution using shear-sensitive liquid crystal coating (SSLCC) is described. The wall shear stress distribution on the test surface beneath high speed jet flow is measured while using the proposed technique. The flow structures inside the jet flow are captured and the results agree well with the streakline pattern that was visualized using the oil-flow technique. In addition, the shock diamonds inside the supersonic jet flow are visualized clearly using SSLCC and the results are compared with the velocity contour that was measured using the particle image velocimetry (PIV) technique. The work of this paper demonstrates the application of SSLCC in the measurement/visualization of wall shear stress in high speed flow. Full article
