Partially the characteristics light aircraft, parameters, flight characteristics, material used for their production, advantages, which improve mobility in suburban urban transport. Currently, materials, procedures, technologies developed development such devices achieve sufficient ...

When designing control laws for systems with constraints on the tracking performance, control allocation methods can be utilized. Control allocation methods are used when there are more command inputs than controlled variables. Control allocators can be used to address surface saturation limits, structural load limits, drag reduction constraints, or actuator failures. Most transport aircraft ha...

The e€ect of present-day and future NOx emissions from aircraft on the NOx and ozone concentrations in the atmosphere and the corresponding radiative forcing were studied using a three-dimensional chemistry transport model (CTM) and a radiative model. The e€ects of the aircraft emissions were compared with the e€ects of the three most important anthropogenic NOx surface sources: road trac, ele...

The Green's function for the transport of ions of high charge and energy is utilized with a nuclear fragmentation database to evaluate dose, dose equivalent, and RBE for C3H10T1/2 cell survival and neoplastic transformation as a function of depth in soft tissue. Such evaluations are useful to estimates of biological risk for high altitude aircraft, space operations, accelerator operations, and ...

Abstract GREENPORT2050 is a project within Clean Sky 2 Technology Evaluator. Its objective to assess the environmental impact up 2050 at airport level of technologies developed in Programme for fixed-wing aircraft. With these assessments, it complements environmental-impact assessments those other two levels Evaluator: aircraft and air-transport system level. This paper provides an overview sys...

SUMMARY This report describes a study that was undertaken on behalf of the Department for Transport to evaluate the Quota Count (QC) system methodology using current data and noise modelling practices. The results indicate that the QC system remains appropriate as a practical means of classifying the noise impact of arriving and departing aircraft.

In order to estimate Reynolds number effects on a transonic transport aircraft CFD calculations have been performed. The CFD calculations have been done solving the RANS equations on an unstructured grid for varying Reynolds number at transonic conditions. Low Reynolds number data have been extrapolated to a higher Reynolds number condition with different scaling methodologies in order to evalu...

The article is devoted to the study and analysis of problems associated with use intelligent technologies in air transport security cybersecurity issues. Possible dangers that may arise when using autonomous systems, including aircraft, are considered. technical measures can be taken prevent these dangers, development new methods protection against hacker attacks, analyzed. problem ensuring int...

Iodotrifluoromethane (CF 3 I) has been considered to be a candidate replacement for bromotrifluoromethane (CF 3 Br), which is used in aircraft for fuel inerting and for fire fighting. In this study, the chemical effects of aircraft-released CF 3 I on atmospheric ozone were examined with the University of Illinois at Urbana-Champaign 5 two-dimensional chemical-radiative-transport (UIUC 2-D CRT) ...
