The plane with electrically energy

Flying by plane as far as 70 mil with only cost 70 American dollar cents has been formed by Randall from New Jersey, USA. In middle of year 1990th, he tried designing plane with electrically energy by using electrically motor in that glider, but the result wasn't good enough.

2 years later, he and his team changed the plane's machine with electrically motor with capacity 18Hp. Designing the place, so that it would be free from more vibration. The body plane was being high 8 inch, so that he could put the propeler with diameter 45 inch.

As the energy source, putted 2 bateries 75-volts lithium-ion-polymeter. By this batery, the plane could fly 70 mil for 90 minutes with only one time batery charging.

How the plane with electrically energy work

• Motor Controller Located in behind the plane parallel with motor and lithium batery. Controller system with computer system only lost 2 percents of energy which through it. This tool could survive the efficiency until 88 percents (compare with 2 strokes machine that only have 15 percents for efficiency).
• Regenerative Motor has function for charging the batery by using fan rotation (propeller) that rotate until velocity 2400 rpm.
• Digital Gauges, tool as voltmeter that has function to know how much watt in batery. the function is almost similar with the measurement of how much the fuel in our vehicles.
• Propeller with diameter 45 inch rotate with velocity about 3100 rpm that has function as the mover of plane for flying.
• Battery Packs has function as the plane's fuel. For the safety of batery is protected by ceramics fireproof and stainless steel.

Now, the plane only can fly by one person rider. Fishman plant to make plane with electrically energy that can take 2 people in 2010th.
