Abstract

New Technologies for Air Traffic Security

Security of increasing intensity of air traffic requires significant technological support. In Europe, the dynamics of this phenomenon will be additionally stimulated by implementation of unmanned aerial vehicles (UAVs) into the air traffic. For effective operation of aircraft fleet it is necessary to employ new on-board diagnostic devices and flight recorders in order to evaluate technical condition of aircraft's instrumentation. Reducing the pilots' workload requires the development of new integrated digital avionics. On the other hand, in order to make the air traffic more secure, it is necessary to develop "sense and avoid" systems not only for UAVs, but for piloted aircraft, as well. On-ground support requires the effective airport/airfield protection and keeping airfield pavements well-maintained and safe.

Abstract

Simulation-Based Approach for Calculating the Reliability of Logistic Support Process

Any operational system, in order to successfully accomplish its intended mission, must rely on logistic support that will be available when required. Moreover, in many systems undesired event occurs later than components failure, if and only if repair is not completed within a grace period. Thus, in the paper there is considered the time dependent system of systems where the system total task must be executed during the constrained time resource. There is used the simulation approach to investigate the influence of parameters of the procurement process (order quantity, critical inventory level, lead-time length) and parameters of time resource on the system of systems behavior.

Abstract

The Aging-Processes-Based Forecasting of Service Lives of Selected Items of Aircraft Equipment

The paper has been intended to present a method of evaluating reliability and service lives of aircraft-equipment items. The evaluation has been based on the description of aging processes that take place throughout aircraft operational phase. What plays the most essential role in this method is the relationship that describes variations in a diagnostic parameter assumed to be a measure of changes in the condition of a given item due to aging processes. The Fokker-Planck equation has been used to describe these variations in the diagnostic parameter. The presented method may be used to control the operational phase of aeronautical devices.

Abstract

The Aging-Processes-Based Forecasting of Service Lives of Selected Items of Aircraft Equipment

The paper has been intended to present a method of evaluating reliability and service lives of aircraft-equipment items. The evaluation has been based on the description of aging processes that take place throughout aircraft operational phase. What plays the most essential role in this method is the relationship that describes variations in a diagnostic parameter assumed to be a measure of changes in the condition of a given item due to aging processes. The Fokker-Planck equation has been used to describe these variations in the diagnostic parameter. The presented method may be used to control the operational phase of aeronautical devices.
