REDEFINING
VERTICAL
AVIATION
Hybrid-electric tilt-rotor aircraft engineered for the most demanding military, firefighting, and critical logistics missions on the planet.
MISSION CAPABILITIES
The Apex Series is purpose-built for missions where speed, payload, and hover precision are simultaneously non-negotiable.
Military Logistics
Rapid resupply and troop transport in contested environments. The Pelican's 6,500 lb payload and 600 nm range redefine theater logistics.
Aerial Firefighting
High-speed retardant delivery and crew transport to active fire lines. Hover precision where fixed-wing aircraft cannot operate.
SAR & MEDEVAC
Long-range search and rescue with the speed of a turboprop and the hover capability of a helicopter.
Offshore Energy
Crew rotation and equipment delivery to offshore platforms in sea states that ground conventional helicopters.
APEX
PELICAN
The Apex Pelican is a 15,279 lb MTOW hybrid-electric tilt-rotor designed for heavy-lift military logistics and large-scale aerial firefighting. Twin LS427 turbocharged gensets drive 8 YASA axial-flux motors, delivering 3,000 hp to four 15-foot CFRP rotor assemblies.
APEX
PEREGRINE
The Apex Peregrine is a 4,800 lb MTOW light utility tilt-rotor optimized for MEDEVAC, SAR, offshore crew rotation, and light military transport. Two twin-turbo Hayabusa gensets drive 6 YASA motors across four 11-foot CFRP rotor assemblies, delivering dual-engine redundancy with 991 NM range.
APEX
PEREGRINE HX
The Peregrine HX is the single-engine high-performance variant of the Peregrine airframe. One Nelson LS427 TT genset delivers 1,500 hp peak, enabling a 6,200 lb MTOW with a 34% hover power margin — the only Peregrine variant capable of continuous hover at full payload. Ideal for MEDEVAC hoist, firefighting, and high-altitude operations.
TECHNOLOGY EDGE
Hybrid-Electric Propulsion
Turbocharged LS427 gensets charge a Skeleton Technologies supercapacitor buffer. YASA axial-flux motors deliver instant torque with zero transmission lag.
CFRP Rotor System
Proprietary 15-ft carbon fiber rotor blades with hingeless hub design. 16-blade configuration per aircraft eliminates vibration and reduces acoustic signature.
Fly-By-Wire Architecture
Garmin G3000 avionics with triple-redundant Honeywell IMU suite. Full envelope protection and autonomous hover hold for single-pilot IFR operations.
JOIN THE MISSION
Helix is seeking strategic partners and investors to accelerate the Apex Series from prototype to FAA certification. A $50M addressable market in military and firefighting rotorcraft awaits.
