Pterosoar

2007

The Pterosoar is a plane designed to break several official FAI world aviation endurance and range records in the F5COMB category (Any sources of current, 5kg limit).  The plane was designed around a Proton Exchange Membrane fuel cell designed and built by Horizon.  To date the airplane has set a world record for distance to point and return.

The Pterosoar was a joint project with California State University Los Angles, Horizon Fuel Cell, and Oklahoma State University as sponsors

Contest Summary: 

 Point and Return    Endurance

Mission

To attempt an official point and return mission, the proposed  launch/landing point, and the turn-around point must be stated before the flight, and signed by the FAI official.  Credit is only given for this distance, and the aircraft must land within a certain distance of the proposed point.

 World Record Attempt Wednesday, September 12, 2007 at 7:30AM PST

The morning of June 2nd was chosen for the light wind conditions predicted.  The flight was to be primarily a range test at partial fuel, since the range capabilities of the airplane had not been fully demonstrated. 

Mission Route Map

After completing preflight checks and signing all appropriate FAI paperwork with the assistance of the FAI observer, Darrell Martin.

The performance of the airplane was better than predicted, and within 15 minutes of launch, the capabilities of the airplane were known.  Landing occurred approximately 3 hours later on a dirt road where which the plane was launched.

Pterosoar flight on September 12, 2007:      120.05 km
