75 HP electric motor and batteries available for ultralight aircraft!

http://www.mountvernonaviationexpo.com – 75 HP electric motor and batteries available for ultralight aircraft! Truly affordable aircraft can be found in Part 103 ultralights but fine as some of these are, their appeal is also limited, for example, most are open cockpit designs.

A void in the availability of a dependable 40-60 horsepower four-stroke aircraft engine may be one reason we see few PSA. Some development of new four-stroke engines is occurring but the ones I've examined are heavier and provide less power than popular two-stroke engines.

How about electric power? — What works with electric propulsion today are low drag, lightweight aircraft that do not require much power to fly. A PSA is nearly perfect in definition. Heavier two-seat aircraft cannot offer the endurance, instilling "range anxiety," and are still too expensive. Until battery energy capacity increases significantly electric power may be limited to PSA.

My personal experience with electric power shows it can be ideal if:

• the aircraft can carry enough battery to fly for an hour (hard to do while meeting Part 103)

• the motor can provide enough power at low RPM (to reduce prop noise closer to electric motor noise)

The entire system can be designed and integrated for safe operation

I have been researching electric power, a technology with huge potential, and I believe a PSA is the perfect place to start. A new electric motor I am developing is designed specifically for aircraft use meaning it has high torque, low RPM, light weight and high reliability.

Concurrently a new battery system I am creating has one of the highest Lithium Polymer (LiPo) power densities commercially available and is integrated with the motor, controller, and battery mana

Electric power can work well using a PSA with today's technology. If properly designed, it should provide an endurance of more than one hour. Those who want to fly farther and faster could couple t
