About

Keiichi Aoki is a pioneering researcher in the field of laser propulsion, with a particular focus on the intersection of micro-aerial vehicle engineering and space exploration technologies. His most notable contribution, the 2002 paper "Laser-driven vehicles: from inner space to outer space," has garnered 15 citations and remains a foundational reference in the field. In this work, Aoki experimentally demonstrated the laser-supported propulsion of a micro-airplane using a water-covered ablator, achieving a critical breakthrough by proving the repetitive use of an overlay structure through a specially-designed water supply system. His research further explored various transparent overlays, combining CIP-based hydrodynamic code simulations with experimental validation to optimize propulsion efficiency. Aoki's work bridges the gap between terrestrial micro-aviation and outer space propulsion, offering innovative pathways for lightweight, laser-driven vehicles. His contributions are particularly significant for students and researchers interested in advanced propulsion systems, demonstrating how controlled ablation and fluid dynamics can enable sustained flight in diverse environments—from Earth's atmosphere to the vacuum of space.
