SolarStratos Returns to Service

SolarStratos, a mission envisioned by Raphaël  Domjan and an airplane designed by Calin Gologan,  returns to the skies after suffering a literal break in its program in 2018. During a series of tests that put increasingly heavy loads on the wings, its left wing broke with what was called a “technical damage.”  This type of breakage during stress testing is not uncommon, especially on what are special machines such as SolarStratos and Solar Impulse.  Solar Impulse 2 suffered a similar break when its newly-designed wing was being tested.  As noted, this type of setback takes the team back to the drawing board, but also besets them with new reflections on their ongoing decisions.  If it were easy, everyone would be …

SolarStratos Damaged During Testing

A terse announcement from the SolarStratos project last week caused some dismay in your editor, but also gave hope that a brave project would go forward. “Payerne, July 6, 2018 – the solar stratospheric SolarStratos aircraft damaged this morning during a resistance test on Earth, in the base of the team at Payerne. No risk:” The bad news, “However, the wing was damaged and its repair will cause a delay in the team’s operational schedule,” was reminiscent of a failure of the Solar Impulse’s wing during static testing.  The break set that project back over a year but resulted in a wing that carried Solar Impulse 2 to Morocco and back, across the U. S., and finally, around the world. …

SolarStratos Construction to Begin in January

Just as we have competing teams working out their plans to cross the Atlantic on electrically-powered wings, several projects are aiming high, attempting to reach altitudes normally achieved only by SR-71 pilots.  With balloon jumps topping 130,000 feet and the Perlan Project in final stages of construction for test flights early next year, the latest entrant in stratosphere-busting climbs will attempt the mission on batteries and solar power. Raphael Domjan, a self-described “eco-adventurer” and founder of Mission SolarStratos, will attempt by 2017 to top 80,000 feet in a two-seat, twin-motored craft designed and built by Calin Gologan and his PC-Aero team.  The airplane, a long-winged derivation of Gologan’s Elektra Two Solar, will rely on recent developments between Gologan and his …
