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.

TECHNOLOGY

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 roughly 400 kg of batteries to fly 250 miles. That is physics, not engineering. Our hybrid replaces most of that mass with a compact hydrogen fuel cell system, saving hundreds of kilograms that go directly into payload, safety margins, and structural integrity. The detailed energy architecture is available to qualified investors under NDA.

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. Values shown are approximate; detailed results available to qualified investors under NDA.

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, and supports our <65 dB design target for residential operations.

PLANFORM (APPROX)

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

Engineered. Validated. Patent-protected.

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.

THE TEAM

Building the future takes the right people.

We are assembling a world-class team of aerospace engineers, propulsion specialists, and aviation industry veterans.
