Helicopter Operations Weather Information Survey Dataset
(Georgia Institute of Technology, 2020-11-23)
To better understand the kind of weather information used by rotorcraft operators and get their opinion on the weather products that are available to them, the research team created an online survey. The survey consisted ...
Helicopter Operations Weather Information Pilot Interviews
(Georgia Institute of Technology, 2021-01-29)
Helicopter pilots face unique challenges with regard to adverse weather when compared to fixed-wing pilots. Rotorcraft typically operate at lower altitudes in off-field areas that are not always well covered by weather ...
Requirements Analysis for Design Optimization of Aerobatic Aircraft
(Georgia Institute of Technology, 2017-01)
Aerobatic aircraft design and simulation is challenging as these aircraft need to fly at any angle of attack and sideslip angle (full-envelope aerodynamics). They fly at velocities close to stall speed, all the way up to ...
Strategies for integrating models of interdependent subsystems of complex system-of-systems products
(Georgia Institute of Technology, 2006)
The Office of Naval Research has established a need for improved design and analysis methods for the next generation of naval surface combatants. The Aerospace Systems Design Lab (ASDL) has initiated the Integrated ...
An Approach for Fan Stage Conceptual Design with Non-Axisymmetric Stators in Presence of Distortion
(Georgia Institute of Technology, 2020-06)
Advances in the study of distortion warrant the consideration of non-axisymmetric flow field impacts on fan designs. The lack of a method that considers such impacts in early design motivates this work. An approach to ...
Sensitivity of Boundary Layer Ingestion Effects to Tube and Wing Airframe Design Features
(Georgia Institute of Technology, 2020-01)
Conceptual design of boundary layer ingesting (BLI) aircraft requires a methodology that captures the aero-propulsive interactions in a parametric fashion. This entails modeling the impacts of BLI as a function of the ...
Integrated Sizing and Optimization of HybridWing Body Aircraft in Conceptual Design
(Georgia Institute of Technology, 2019-06)
The hybrid wing body (HWB) configuration is a paradigm shift in commercial transport aircraft design in terms of environmentally responsible characteristics and significant performance improvements over the conventional ...
A Coupled Approach to the Design Space Exploration of Nuclear Thermal Propulsion Systems
(Georgia Institute of Technology, 2020-08)
Nuclear Thermal Propulsion (NTP) is identified as one of the preferred propulsion technologies for future manned missions to Mars and other interplanetary destinations. NTP systems can improve the returns and mitigate the ...
Exploring the Design Space of an Electric Ship using a Probabilistic Technology Evaluation Methodology
(Georgia Institute of Technology, 2019-08)
With the advent of new technologies for electric ships, there is a need for a robust methodology to quantitatively evaluate their impact on the performance of a ship, while accounting for the uncertain nature of their ...
Dynamic Simulation of Vehicle Maneuvers for Loads Analysis
(Georgia Institute of Technology, 2020-06)
Testing critical loads during specific dynamic maneuvers is essential to aircraft structural design, and several such dynamic load cases must be demonstrated during the certification process. A simulation capability is ...
