OUR VISION

Everyone told us personal flight was impossible.
We found a way.

Battery-only eVTOLs max out at 80-100 miles. Air taxis need billion-dollar infrastructure. Traditional certification takes a decade. Everyone accepted these as facts.

We didn't. Project Aether combines three breakthroughs that nobody else has put together: hybrid hydrogen propulsion for real range, the FAA's brand-new MOSAIC certification for speed to market, and additive manufacturing for a price point that opens up the market.

250+ mile range

Hydrogen fuel cells for cruise, batteries for hover. Best of both worlds.

2-3 year certification

MOSAIC pathway, not traditional Type Cert. AIR proved it works in 2025.

$195K target price

Additive manufacturing + modular design = automotive-scale economics.

Hybrid Hydrogen-Electric Propulsion

Our power system uses batteries for hover and hydrogen fuel cells for cruise. The fuel cell recharges the battery in-flight, so you land with more battery than you need.

KEY INSIGHT

A battery-only eVTOL needs ~120 kWh (400 kg) for 250 miles of range. Our hybrid achieves the same with a 25 kWh battery (72 kg) + 5 kg hydrogen + 50 kg fuel cell system. We save 273 kg — that goes directly into payload, safety margins, and structural integrity.

VALIDATION

Preliminary CFD Analysis

External aerodynamic simulation at 160 mph cruise, 25° wing tilt. Passive airflow analysis — fans not powered. Performed using AirShaper cloud CFD platform.

CFD streamlines showing airflow over Aether eVTOL at cruise
STREAMLINES

Velocity-colored streamlines show clean laminar flow over the fuselage and controlled separation at the tilted wings. Flow disruption at duct openings is expected — eliminated in powered flight when fans are active.

Surface pressure distribution on Aether eVTOL
PRESSURE DISTRIBUTION

Surface pressure coefficient (Cp) visualization confirms aerodynamic lift generation on the tilted wing surfaces. Low pressure (blue) on upper surfaces, high pressure (red) on lower surfaces — classic lift signature.

Drag visualization on Aether eVTOL
DRAG ANALYSIS

Total pressure coefficient shows primary drag sources at the ducted fan openings. With fans operating in cruise, airflow through the ducts becomes streamlined, significantly reducing the passive drag penalty shown here.

Surface friction on Aether eVTOL
SURFACE FRICTION

Skin friction distribution reveals boundary layer behavior. Higher friction at the nose (stagnation point) and wing leading edges confirms proper flow attachment — the airfoil profiles are working as designed.

Acoustic noise map of Aether eVTOL
NOISE SIGNATURE

Aeroacoustic analysis shows noise concentrated at the wing-fuselage junctions and duct edges, with a predicted 7–9 dB/m³ range. Supports our <65 dB design target for residential operations.

PLANFORM AREA

Passive CFD — unpowered ducts act as drag bodies. With fans operating, effective Cd drops significantly and L/D ratio increases to the 8–12+ range predicted by our vortex lattice analysis. Full powered CFD validation planned for prototype phase.

THE AIRCRAFT

Designed to be flown by anyone.

Tandem Tilt-Wing

Forward and aft wings rotate 90° for vertical takeoff, then tilt to 25° for efficient cruise at 140 mph. Cruise angle validated by computational fluid dynamics.

8 Ducted Fans

Enclosed propellers embedded in the wings. 30% more thrust than open props, dramatically quieter, and safe to walk near on the ground.

Foldable Wings

Both wing sets fold for storage. Footprint collapses to 8×20 ft — fits in a standard two-car garage. No hangar needed.

Fly-by-Wire

Triple-redundant flight computers handle everything. One sidestick, one power lever. Sport Pilot certificate with just 15 hours of training.

Panoramic Canopy

270° bubble canopy with electrochromic auto-tinting. HUD projection on the inner glass. Emergency jettison system.

Ballistic Parachute

Whole-aircraft recovery system deploys in under 1 second. Full MTOW rated above 200 ft. Because safety is non-negotiable.

FLIGHT CENTERS

Own it. Or rent it.
Fly anytime, anywhere.

Aether serves two markets: personal owners who buy their own aircraft, and flight centers that rent to Sport Pilots by the hour. No schedules. No TSA. No vertiports. Just flight.

FOR PERSONAL OWNERS

$195K

Your aircraft, your schedule. Take off from your driveway, fly 250+ miles, land anywhere. Folds to fit in a standard two-car garage.

Sport Pilot certificate: 15 hours of training
H₂ tank exchange in 5-10 minutes
Carries two passengers
No hangar required
FOR FLIGHT CENTERS & FBOs

$250/hr rental

Buy a fleet of 10-20 aircraft. Rent to licensed Sport Pilots by the hour. We supply the hydrogen, the maintenance, and the booking platform.

Uses existing airfields — no vertiports needed
Pilots fly themselves or carry a passenger
On-demand, no fixed schedules
Aircraft payback in under 12 months
DC TO NEW YORK: 1 HOUR 40 MINUTES

A Sport Pilot walks into a DC flight center, rents an Aether, and flies to New York in under 2 hours for $250-350. No TSA. No delays. No schedule. Faster than Acela, cheaper than business class. The pilot can also fly a paying passenger — on-demand air travel without the air taxi infrastructure.
