VIABLE AND AFFORDABLE ELECTRIC AIRCRAFT IN 2015

But first: 3-1/2 Decades of aviation in 3-1/2 minutes

The 1980s: Ultralights Era

The 1990s: Microlights Era

• Moved to the Czech Republic

• Manufactured >500 Zenairaircraft

• Won Picolla Schnieder Cup Seaplane race 3 times

• Greek National UL Champion

The 2000s: Light Sport Aircraft Era

The 2010s: China Era

Set up 2 factories and 3 production lines in China

WHICH AIRCRAFT WORK TODAY ON ELECTRIC?

What works now?

4 of 5 Requirements to work:

• Low Speed

• Low Drag

• Light Weight

• Certification Standard

• Affordable

Unobtainum?

My Electric Plan:• Develop new aircraft-specific motor

• Cut propeller noise by 80%

• Develop safe and high power-to-weight ratio battery system and integration

• Design new PSA aircraft around electric power and certification constraints

OUR NEW MOTOR• Low rpm: 1,200 @ cruise power• Twin rotor for efficient cooling• Synchronous Axial Flux design• 3-Phase AC

• Custom design specifically for aircraft• Competitive pricing & available for OEM• 55 Kw theoretical power • 12 Kg weight

OUR NEW BATTERY SYSTEM• Carbon/Kevlar-sleeved cylinders for safety

• Flexible configurations & no heavy case

• Excellent cooling

• Cells are 65 Ah LiPo Cobalt and 3.7 volts nominal

• Lightest ‘total system’ in Kw/Kg on the market

• Integrated 350 Amp controller and BMS

• 2.5 hour recharge. 2,000 cycles

Safety is our priority!1. Cylinders prevent gas

expansion. Cell producer has zero failures.

2. Integrated BMS3. Cell cooling4. Battery Management

Monitor5. Pilot education

NEXT YEAR: RANGE EXTENDER HYBRIDS

7 minutes or 2 hours?

How about an Electric Amphibious Aircraft?How cool would that be?

Noise is just about the biggest problem seaplanes have and a seaplane with our electric system will be nearly silent!

An electric amphib that would sell for only $50,000!

This can become a reality this year!Our new amphibious float design is now finished.
