Technology

How it Works
^

plane
  • The engine is located in the fuselage aft of the passenger compartment behind a 6 inch sound proof, noise and fire barrier.
  • This places the engine and thrust location adjacent to the center of lift on the wing.
  • The engine drives two ducted fan propulsion pods

propulsion system
  • The two ducted fan assemblies move twice the volume of air at twice the velocity when compared to a conventional propeller
  • The duct configuration permits the inclusion of a stator which increases efficiency in terms of air management

Features
^

plane
  • Comfortable silent 6 passenger cabin (H325)
  • Liquid cooled engine provides operating efficiency and interior comfort
  • The location of the engine permits sufficient space to locate state of the art mufflers in the tailcone

plane
  • 350 hp liquid cooled V8 engine (H325)
  • Latest electronic engine technology
  • Liquid cooled for operating efficiency and interior comfort

plane
  • Twin counter rotating ducted high thrust propulsion fans
  • Latest avionic suite
  • Retractable undercarriage
  • Full-time anti-icing protection using engine system coolant to melt ice

Differences
^

Environmentally friendly

  • Runs on unleaded automotive fuel or 100 LL interchangeably Burns only 10 gallons of fuel per hour

Passenger friendly

  • Cruises at 300 plus knots at 28,000 feet
  • The interior is as quiet as a luxury car
  • Can land at more airports – on shorter runways

Neighbor friendly

  • The engine sounds like a luxury car
  • Leaves no sound footprint beyond 300 ft vertical and 100 ft horizontal
  • Has no jet whine or propeller slap

Operator friendly

  • Is scalable from 4 to 32 passengers
  • Operating and maintenance costs that are up to 40% lower than current technology

Trip Cost Comparison
^

The following is a trip operational comparison between an automobile and several commonly used aircraft all flying/driving the same route between a major city in the north east say Toronto, Canada and Miami.
Type Engines Speed En-route
Time
Altitude Payload Fuel used Cost
Buick auto 1 50 mph 27 hrs. Ground 1,000 lbs 68 gals. $136
Piper Aztec 2 170 kts. 6.8 hrs. 8,000 ft. 650 lbs. 190 gals. $530
Hines H325 1 300 kts. 3.8 hrs. 28,000 ft. 1,200 lbs. 38 gals. $105
King Air 200 2 275 kts. 4.2 hrs. 26,000 ft. 2,200 lbs. 380 gals. $1,064
Learjet 35 2 400 kts. 2.9 hrs. 38,000 ft. 1,000 lbs. 536 gals. $1,500
Notes:
  1. We assume a distance of 1150 nautical miles in the air and 1350 statute road miles for the car.
  2. The car gets 19-20 MPG.
  3. Automotive fuel is assumed to cost $2.00 per gallon and aviation fuel is assumed at $2.80 per gallon.
  4. Speeds are average and include time to climb maneuvering, approach and land.
  5. The Buick burns an average of 2.52 GPH and is powered by a 175 hp V6 engine
  6. The Piper Aztec is powered by 2 Lycoming 250 HP IO540 Turbo Charged engines. I have assumed high cruse speed with aircraft in peak condition. Requires 1 fuel stop.
  7. The H325 is powered by an aluminum V8 developing 350 HP net. The H325 can run on automotive fuel but it is assumed we used avgas here.
  8. The King Air has 2 P&W PT6 engine developing 950 SHP
  9. The Lear 35 has Garret engines developing 3600 lbs of thrust each. We assume 250 gal of fuel the first hour then 200 each hour thereafter.
