Scaling considerations for small aircraft engines
Small aircraft engines traditionally have poorer performance compared to larger engines, which until recently, has been a factor that outweighed the aerodynamic benefits of commoditized and distributed propulsion. Improvements in the performance of small engines have, however, prompted another look …

Integration of the Transportation Systems Analysis Model for the Small Aircraft Transportation System
Standalone computer modules for county to county travel demand forecasting have been integrated. The Trip Generation, Trip Distribution and Mode Choice modules have been unified under one Graphical User Interface (GUI). The outputs are automatically mapped using Geographic Information Systems (GIS) …

A Modeling and Simulation Approach to the Small Aircraft Transportation System: Assessing Midair Conflict Potential Under the Free Flight Paradigm
The Small Aircraft Transportation System, or SATS, is a NASA-led initiative that seeks to revolutionize commercial air travel by increasing accessibility and mobility for the general consumer. The hallmark of SATS is on-demand, point-to-point air transportation from one of the nation's 5,400 public …

Essays on airport and airway congestion
… fees) are currently designed to tax large aircraft more than small aircraft and flights with more passengers more than flights with few passengers. Several authors have argued that these taxes and fees create an incentive system for airlines to use small aircraft with high frequency, which …

The influence of runway occupancy time and wake vortex separation requirements on runway throughput
… Surface Detection Equipment Model-X (ASDE-X) aircraft surveillance data. The findings of this study indicate that runway occupancy does not necessary scale with aircraft size. Small aircraft often occupy the runway as long as large aircraft, which limits the potential for reduced separations …

Development of low-thrust solid rocket motors for small, fast aircraft propulsion
Small, uncrewed aerial vehicles (UAVs) are expanding the capabilities of aircraft systems. However, a gap exists in the size and capability of aircraft: no small aircraft are capable of sustained fast flight. A small, fast aircraft requires a propulsion system which is both miniature and …
