The Silicon Valley of Drones | Robert Lunnie

Update: 2025-08-14

Description

In this episode of Hangar X Studios, host John Ramstead sits down with aerospace professor and Air Force veteran Robert Lunnie, live from VertiCon. Together, they dive into the challenges and breakthroughs of designing vertical take-off and landing (VTOL) aircraft, focusing on subscale prototyping, flight testing, and real-time transition from vertical to horizontal flight.

Lunnie walks us through his collaborative work with XTI Aerospace, explains the development process behind experimental models like the TriFan, and shares how the University of North Dakota (UND) has become a powerhouse in drone R&D and autonomous flight systems. This episode is a deep technical dive into the future of flight and the dynamic ecosystem driving aerospace innovation.
