From Wright Brothers 1903 to present day 2003, aeronautical technology has made a profound progress. This paper demonstrates the outcome of this progress in weight, wing area, and engine thrust in three categories of transport aircraft of short to long range, regional jets, and turbo-prop commuter aircraft. Also the paper includes those aircraft with distinct jump in aeronautical technology. Fe...

This paper deals with the study and comparison of passive and active landing gear system of  the aircraft and dynamic responses due to runway irregularities while the aircraft is taxying. The dynamic load and vibration caused by the unevenness of runway will result in airframe fatigue, discomfort of passengers and the reduction of the pilot’s ability to control the aircraft. One of the objectiv...

Managing operations of the aircraft approach process and analyzing runway landing capacity, utilization and related risks require detailed insight into the stochastic characteristics of the process. These characteristics can be represented by probability distributions. The focus of this study is analyzing landings on a runway operating independent of other runways making it as a single runway. ...

Currently, the use of light steel thin-walled structures from roll-formed sections in industrial and civil construction is increasing. Studies strength properties these will lead to development entire industry, including aviation which includes development, manufacture installation using bent profiles.
 The study tested influence deplanation cross-section thin-sheet plates on their by vari...

This work provides a feasibility and effectiveness analysis, through numerical investigation, of metal replacement primary components with composite material for an executive aircraft wing. In particular, benefits disadvantages replacing metal, usually adopted to manufacture this structural component, are explored. To accomplish task, detailed FEM model the wing was deployed by taking into acco...

Abstract. Aircraft wing manufacture is becoming increasingly digitalised. For example, it possible to produce on-line digital representations of individual structural elements, components and tools as they are deployed during assembly processes. When comes monitoring a manufacturing environment, imaging systems can be used track objects move about the workspace, comparing actual positions, alig...
