Commercial aviation maintenance related incidents reported to the Aviation Safety Report System were investigated focusing on coordination problems. Among 1000 analyzed reports from a two-year period, 98 internal coordination issues within the maintenance team, and 24 external coordination issues between maintenance and other departments were discovered. Frequently established problematic inclu...

As three-dimensional (3D) printing technology is widely used, security issues have arisen, especially in the terminal parts of automobiles, aircraft, and 3D-printed military equipment. If original design models or STL (stereolithography) files are hacked tampered, severe consequences can be anticipated. In this paper, we propose a demonstration to use high-throughput blockchain store “fingerpri...

As the requirement of task is dynamical, the usage of equipment will change with time and it will result in the fluctuating demand for spare parts all over the time. In order to improve equipment performance, the users need to forecast equipment failure frequency and demand for spare parts within the task period. Demand in a moment of task period is the result of cumulative effect of the failur...

A computer-based mathematical model is developed fqr the estimation of assessment of damage inflicted on an aircraft due to a ground-h,lscd air dcfcnce gun. It is assllmcd that thc aircraft is approaching thc targct from an arbitrary dircction and docs not changc it's trajectory during gun firing. Dimension of aircraft and trajcctory of warhead are assumed to be known. Damage to aircraft is cau...

Systems continuously monitoring crew member psychophysiological status implemented in the advanced aircraft avionics suit will become effective measure of flight safety promotion, as more than 70% flight accidents are connected to «human factor». Standard recording equipment on modern aircraft records up to several hundred different indexes for monitoring flight parameters and on-board equipmen...

Abstract The capability of wire and arc additive manufacturing (WAAM) to produce large, near-net-shaped parts with inexpensive equipment has led the process being considered as one options significantly decrease buy-to-fly ratio in aircraft manufacture. Even so, there are several challenges associated process: achieving mechanical properties microstructure similar wrought material, well low sur...

The Small Aircraft Transportation System (SATS) is a partnership between the FAA, the NASA, US aviation companies, universities and state and local aviation officials. The purpose of SATS is to develop a system to handle future increase in Air Traffic, reduce time-travel, develop automation in Air Traffic Control (ATC) and make better use of small aircraft and underused airports. The Smart Land...
