Regional and Business Aircraft Mission Emissions

Volume 3: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations, 1994
To meet the design requirements of next generation aircraft engines and the expected trends of more stringent emissions regulations, better calculation methods for aircraft mission emissions need to be established. In the present investigation, a number of steps were taken to define an appropriate calculation technique.

Regional Aircraft Family Design

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">A design concept of an aircraft family (55 -, 70-, 100-seater) is presented. Started with the reference model of 70-seater, a stretch to 100-seater and shrink to 55-seater is considered ab intio. Impact of commonality in a fleet of different size aircraft is investigated.

Virus Transport Aboard Commercial Regional Aircraft

44th AIAA Fluid Dynamics Conference, 2014
Air ventilation systems in aircraft cabins are used to create a comfortable environment for travelling passengers. However, droplets exhaled by passengers with infectious diseases have a potential to affect and contaminate other passengers. The present study is the first part of several ongoing investigations at CEERS on indoor air quality and health ...
