Autonomous Parafoil Flaring Control System for eVTOL Aircraft

Aerospace
Reducing landing kinetic energy during emergency landings is critical for minimising occupant injury in eVTOL aircraft. This study presents the development of an autonomous parafoil control system for impact point targeting and flare control. A model predictive controller for a six-degree-of-freedom parafoil and eVTOL payload model was designed ...

Drone‐Assisted Organ Transport: A Scoping Review of Clinical, Regulatory, and System Readiness

Clinical Transplantation, Volume 39, Issue 12, December 2025.
ABSTRACT Organ transport remains a critical determinant of transplant success, with delays during transfer prolonging cold ischemia time (CIT) and increasing the risk of delayed graft function or organ discard. Uncrewed aerial vehicles (UAVs) have emerged as a potential means to enhance the speed, predictability, and resilience of transplant logistics.
