About Us

NAC – is a deep-tech aerospace company developing the next generation of hybrid-electric tiltrotor aircraft. Our mission is to redefine vertical aviation by creating an intelligent aircraft platform that combines the vertical takeoff and landing capabilities of a helicopter with the speed, range, and efficiency of a fixed-wing aircraft. Today's tiltrotor aircraft—including the V-22 Osprey, MV-75, and Leonardo AW609—have demonstrated the remarkable advantages of tiltrotor technology. However, they continue to rely on conventional turboshaft engines, complex mechanical transmissions, hydraulic systems, and traditional flight control architectures. At NAC, we believe the next generation of tiltrotor aircraft requires a completely new architecture. The SkyLine Sentinel program is being developed around a modern hybrid-electric architecture featuring distributed axial-flux electric propulsion, megawatt-class power generation, electric proprotor pitch control, electric tilt actuation, AI-assisted Fly-by-Wire, intelligent energy management, and advanced flight control technologies. This architecture is designed to reduce mechanical complexity, improve efficiency, enhance safety, and lower long-term operating and maintenance costs. Designed from the outset for both civil and defense operations, SkyLine Sentinel is intended to support regional passenger transport, cargo logistics, emergency medical services, search and rescue, offshore operations, government missions, and defense applications—all on a common aircraft platform. Our vision goes beyond building an aircraft. We are creating a next-generation aerospace ecosystem that advances innovation, creates highly skilled jobs, expands export opportunities, and positions our nation among the world's leading developers of advanced hybrid-electric tiltrotor aircraft. Innovating the Future of Vertical Flight.
