Benchmark Analysis of Semantic Segmentation Algorithms for Safe Planetary Landing Site Selection
(2022-04)This paper presents an in-depth analysis of state-of-the-art semantic segmentation algorithms applied to spacecraft safe planetary landing via hazard detection and avoidance. Several architectures are trained from binary ... -
Sensitivity Analysis of the Overwing Nacelle Design Space
(Georgia Institute of TechnologyAmerican Institute of Aeronautics and Astronautics, 2022-06-09)The overwing nacelle (OWN) concept refers to aircraft designs where the engine is installed above the wing. The OWN configuration offers several advantages over conventional underwing nacelle (UWN) vehicles, which include ... -
Conceptual Design of Boundary Layer Ingesting Aircraft Capturing Aero-Propulsive Coupling
(Georgia Institute of TechnologyAmerican Institute of Aeronautics and Astronautics, 2022-03-01)The impacts of boundary layer ingestion on aircraft performance can be modeled using either a decoupled or a coupled approach. Several studies in literature have adopted the former, while some have shown differences between ... -
