Boeing's Solar Spy Plane Could Fly for Five Years Straight
Political correctness aside, Boeing’s proposed solar-powered spy plane is really freakin’ cool: the company says the plane it’s building for the DOD will be able to fly unmanned for five years straight. Not unlike the Solar Impulse, Boeing’s SolarEagle will feature hyper-efficient electric motors and propellers and long wings covered in solar cells that store energy by day to achieve constant flight.
Designed for stealthy altitudes above 60,000 feet, the spy plane will use the sun’s energy to power constant surveillance communications. Boeing received an $89 million DARPA contract to develop a prototype plane, which will attempt to perform a month-long test mission by 2014.
