Aerodynamic Design Optimization of a Transonic Strut-Braced-Wing Regional Aircraft

Journal of Aircraft, 2021
The aerodynamic design and fuel burn performance of a Mach-0.78 strut-braced-wing regional jet is investigated through aerodynamic shape optimization based on the Reynolds-averaged Navier–Stokes eq...

Regional fanjet aircraft optimization studies

Journal of Aircraft, 1991
This article illustrates the use of optimization methods in the development of a new regional aircraft. These aircraft are more sensitive to changes in operational requirements than other types due, in part, to their high zero-fuel weight ratio. For such aircraft it is essential that the best information possible be available to the designers in the ...

Aircraft Noise, Airport Growth and Regional Development

10th AIAA/CEAS Aeroacoustics Conference, 2004
This paper considers the link between aircraft noise, airport growth and regional development. It examines the important difference between noise exposure, noise impacts and the resulting disturbance and how social, economic and attitudinal factors can affect actual and perceived levels of noise nuisance.

Hybrid-Electric Regional Jet Aircraft Operation Efficiency

AIAA Propulsion and Energy 2019 Forum, 2019
This work investigates the affect modifying the operation strategy during cruise has on hybrid-electric regional jet performance. Specifically investigated are mission range, fuel burn, and carbon dioxide emissions from fuel and battery sources. Accompanying the results from the hybrid-electric aircraft simulation is an investigation into the national ...

Powertrain Model Improvement for Hybrid-Electric Regional Aircraft

AIAA SCITECH 2022 Forum, 2022
This paper deals with the definition of an improved powertrain model for hybrid-electric aircraft. It is well known that powertrain equations are one of the most convenient tools for modelling the propulsion system at aircraft level, when it comes to hybrid architectures characterized by more than a single propulsive source.

Analysis of GNSS-R Coverage by a Regional Aircraft Fleet

IEEE International Geoscience and Remote Sensing Symposium, 2020
Airborne GNSS-R instrument systems are typically only utilized for a limited number of aircraft flights to perform experiments, to test new instruments, and to collect data over specific targets (e.g. hurricanes).

Advanced Technology for Future Regional Transport Aircraft

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">In 1978, NASA established a Small Transport Aircraft Technology (STAT) team to study whether there are technical improvements in commuter aircraft that would likely increase their public acceptance and use, and to examine the possibility that NASA’s aeronautical research and technology program could help U.S ...
