The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Hybrid Deep Learning‐Based Networks for Deterministic and Probabilistic Wind Nowcasting Within a Wake Vortex Warning System for Vertiport Operations

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
This paper proposes an innovative framework for deterministic and probabilistic wind nowcasting consisting of various machine learning methods. The reliable short‐term wind predictions drive the Wake Vortex Warning System for Vertiports (WVWS‐V), which may enable safe air‐taxi operations at major airports. ABSTRACT Accurate wind prediction is essential

Addressing Complexity in System of Systems With GraphRAG: An AI‐Driven Framework for Dynamic Data Integration

Systems Engineering, Volume 29, Issue 2, Page 150-168, March 2026.
ABSTRACT System of Systems (SoS) environments are inherently complex, involving numerous operationally and managerially independent component systems with hidden interdependencies and frequent interactions based on unstructured data. In this paper, we propose using graphical Retrieval‐Augmented Generation (GraphRAG), a tool that combines large language

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.
