AVERON AEROSPACE (formerly NAC)
NAC is developing the SkyLine Sentinel, a next-generation hybrid-electric tiltrotor aircraft that combines helicopter vertical takeoff and landing with fixed-wing speed and range. The clean-sheet design targets a 450 km/h cruise speed and 4,000 km ferry range, with distributed axial-flux electric propulsion and electric tilt actuation to reduce mechanical complexity and operating costs.

Problem
Conventional air transportation faces a fundamental trade-off: helicopters offer vertical takeoff and landing access to remote areas but suffer from limited range and high operating costs, while airplanes provide efficient long-range travel but depend on developed airport infrastructure. In mountainous, desert, island, coastal, and other remote regions worldwide, this infrastructure often does not exist, leaving communities without reliable access to essential aviation services such as air ambulance, cargo delivery, and emergency response.
Solution
NAC is developing the SkyLine Sentinel, a next-generation tiltrotor aircraft built on a hybrid-electric architecture that unifies helicopter flexibility with fixed-wing efficiency in a single platform. The aircraft is designed to perform vertical takeoff and landing while cruising at up to 450 km/h with a ferry range of up to 4,000 km, significantly outperforming conventional rotorcraft. The clean-sheet design incorporates distributed axial-flux electric propulsion, megawatt-class power generation, electric proprotor pitch control, and electric tilt actuation to reduce mechanical complexity and lower operating costs. The platform is intended to serve multiple mission types without requiring operators to purchase separate helicopters and airplanes, bringing aviation access to regions where conventional air transportation remains economically or infrastructurally challenging.
Target Audience
Primary customers include government agencies, humanitarian organizations, air ambulance providers, cargo operators, and passenger transport companies operating in regions with limited aviation infrastructure or vast territories that require long-range mobility with VTOL access.
