Assessing Multi-rotor UAV Controllability in Low Altitude Fine-Scale Wind Fields
(2019-09-03)This study presents a means of assessing unmanned aerial vehicle (UAV) control in various environments using control margin. The metric gives an instantaneous measure of control authority and is defined by dividing ... -
Non-stop versus connecting air services: Airfares, costs, and consumers’ willingness to pay
(2019-06-28)Airlines provide both non-stop and connecting services. The airfare for each service type is determined largely by the willingness to pay (WTP) of passengers and the costs for airlines. This paper estimates the impact ... -
A Geometric Approach Towards Airspace Assessment for Emerging Operations
(2019-06-14)Emerging Urban Air Mobility (UAM)operators propose to introduce extensive flight networks into metropolitan airspace.However,this airspace currently contains complex legacy airspace constructs and flight operations that ... -
Manufacturing Methods for a Solid Rocket Motor Propelling a Small, Fast Flight Vehicle
(2019-06-05)A gap exists in the design space for aircraft mass and speed: no flight vehicles with a mass of less than 10 kg and speed greater than 100 m/s are available. The small, fast "Firefly" flight vehicle is being developed to ... -
Assessing Integration Between Emerging and Conventional Operations in Urban Airspace
(2019-05-31)This paper investigates the use of low altitude airspace by conventional flight operations in proximity to the San Francisco, Boston, and Atlanta international airports. The purpose of the investigation is two-fold. First, ... -
Aircraft Noise Modeling of Dispersed Flight Tracks and Metrics for Assessing Impacts
(2019-05-22)The implementation of Performance Based Navigation (PBN), such as Area Navigation (RNAV) and Required Navigation Performance (RNP), has led to aircraft being able to fly designed flight tracks very precisely. This has led ... -
A Petri Net Framework for the Representation and Analysis of Aircraft Turnaround Operations
(2019-05-20)Aircraft turnaround operations is a key determinant of both airline and airport performance. Airlines incur both direct and indirect costs from poor on-time departure performance, particularly when these delays propagate ... -
Investigating Collision Avoidance for Small UAS using Cooperative Surveillance and ACAS X
(2019-05-20)Small Unmanned Aircraft Systems (sUAS) have proliferated over the last decade. While these platforms offer many benefits to society, they pose a dangerous mid-air collision hazard. In order to safely integrate into airspace ... -
Data-Driven Modeling of Air Traffic Flows for Advanced Air Traffic Management
(2019-04-26)The Air Traffic Management (ATM) system enables air transportation by ensuring a safe and orderly air traffic flow. As the air transport demand has grown, ATM has become increasingly challenging, resulting in high levels ... -
