Collaboration is a key enabler for the development of modern aircraft and its systems and components. Because of the highly complex and integrated nature of many aircraft systems, effective collaboration requires well-organized multidisciplinary , multi-engineer and multiorganization development processes. These processes require data-driven and co...
Road traffic simultaneously emits noise and air pollution. This relation is primarily assessed by comparing A-weighted noise levels (LAeq) and various air pollutants. However, despite the common local traffic source, LAeq and the various sets of air pollution show a lower correlation than expected. Prior work, using simultaneous mobile noise and ai...
There is increasing evidence of potential health impacts from both aircraft noise and aircraft-associated ultrafine particles (UFP). Measurements of noise and UFP are however scarce near airports and so their variability and relationship are not well understood. Particle number size distributions and noise levels were measured at two locations near...
It is difficult to observe people's actual evacuation behavior in case of a real aircraft accident. For one, luckily, because aircraft incidences have very low probabilities, and for another, because when faced with such extreme situations people often resort to very unexpected behavior. A way to obtain people's responses to an airplane emergency i...
Tato diplomová práce se zabývá studií a návrhem konceptu dispozice interiéru v leteckém dopravním prostředku Zuri Four. Jedná se o takzvaný VTOL (Vertical Take-Off and Landing). Je to dopravní prostředek schopný vzlétnout a přistát ve vertikálním směru. Samotný let je ale již ve směru horizontálním. Technologie je v současnosti pro masovou dopravu ...
Fidelity is a fundamental concept for crucial decision-making processes during engineering design, test and evaluation of aircraft and rotorcraft. Fidelity, as applied to rotorcraft, proves to be a prerequisite for most human factors research and simulator development programs. This paper reviews the concept of fidelity, its metrics and methods con...
A hybrid excitation brushless dc generator (HEBLDCG) system, consisting of a main generator (MG) and an integrated exciter, is proposed and developed in this article. The excitation sources types of the stand-alone generation system and corresponding characteristics of the sources types are summarized. In the target HEBLDCG system, the integrated e...
The global aviation industry adopted a set of targets to mitigate CO2 emissions resulting from air transportation in 2009. The engine fuel burn is the main driver of CO2 emission; hence it will be the focus of this study. Rotorcraft are designed for supporting different types of missions or operations that are different from fixed wing aircraft. Fo...

Nature abounds with examples of animals which decrease their energy expenditure by gliding off the bow waves of large moving objects, riding thermals, or flying in efficient configurations. The past twenty years has seen significant advances in the scientific understanding and feasibility of large aircraft saving energy by flying in advantageous pa...
