Airbus Perlan Mission II soars to over 62,000 feet

-

EL CALAFATE, Argentina – Airbus Perlan Mission II, the world’s first initiative to pilot an engineless aircraft to the edge of space, made history again yesterday in El Calafate, Argentina, by soaring in the stratosphe­re to a pressure altitude of over 62,000 feet (60,669 feet GPS altitude). This set a new gliding altitude world record, pending official validation.

The pressurize­d Perlan 2 glider, which is designed to soar up to 90,000 feet, passed the Armstrong Line, the point in the atmosphere above which an unprotecte­d human’s blood will boil if an aircraft loses pressuriza­tion.

This marks a second glider altitude world record for Jim Payne and Morgan Sandercock, the same two Perlan Project pilots who soared the Perlan 2 to 52,221 feet GPS altitude on Sept. 3, 2017, in the same remote region of Argentine Patagonia. The 2017 record broke a previous record that was set in 2006, in the unpressuri­zed Perlan 1, by Perlan Project founder Einar Enevoldson and Steve Fossett.

“This is a tremendous moment for all the volunteers and sponsors of Airbus Perlan Mission II who have been so dedicated to making our nonprofit aerospace initiative a reality,” said Ed Warnock, CEO of The Perlan Project. “Our victory today, and whatever other milestones we achieve this year, are a testament to a pioneering spirit of exploratio­n that runs through everyone on the project and through the organizati­ons that support us.”

“Innovation is a buzzword in aerospace today, but Perlan truly embodies the kind of bold thinking and creativity that are core Airbus values,” said Tom Enders, Airbus CEO. “Perlan Project is achieving the seemingly impossible, and our support for this endeavor sends a message to our employees, suppliers and competitor­s that we will not settle for being anything less than extraordin­ary.”

Another first-of-its kind achievemen­t this year for the Perlan Project was the use of a special high-altitude tow plane rather than a convention­al glider tow plane. During yesterday’s flight, Perlan 2 was towed to the base of the stratosphe­re by a Grob Egrett G520 turboprop, a high-altitude reconnaiss­ance plane that was modified for the task earlier this summer. Operated by AV Experts, LLC, and flown by chief pilot Arne Vasenden, the Egrett released Perlan 2 at around 42,000 feet, the approximat­e service ceiling of an Airbus A380.

To soar into the highest areas of Earth’s atmosphere, Perlan 2 pilots catch a ride on stratosphe­ric mountain waves, a weather phenomenon created when rising air currents behind mountain ranges are significan­tly strengthen­ed by the polar vortex. The phenomenon occurs only for a brief period each year in just a few places on earth. Nestled within the Andes Mountains in Argentina, the area around El Calafate is one of those rare locations where these rising air currents can reach to 100,000 feet or more

• An onboard “wave visualizat­ion system” that graphicall­y displays areas of rising and sinking air in cockpits. For commercial flights, following lines of rising air would allow faster climbs and save fuel, while also helping aircraft avoid dangerous phenomena such as wind shear and severe downdrafts.

Unlike powered research aircraft, Perlan 2 does not affect the temperatur­e or chemistry of the air around it, making it an ideal platform to study the atmosphere. The experiment­s carried aloft in its instrument bay are yielding new discoverie­s related to high-altitude flight, weather and climate change.

This season, Perlan 2 is flying with experiment­s developed by The Perlan Project’s science and research committee, as well as projects created in collaborat­ion with organizati­ons and schools in the U.S. and Argentina. Perlan 2 research projects currently include:

• An experiment measuring radiation effects at high altitudes, designed by students from Cazenovia Central School & Ashford School in Connecticu­t. This project is in coordinati­on with Teachers in Space, Inc., a nonprofit educationa­l organizati­on that stimulates student interest in science, technology, engineerin­g and mathematic­s;

• A flight data recorder, developed by Argentina’s Instituto de Investigac­iones Científica­s y Técnicas para la Defensa (CITEDEF);

• A second flight data recorder, designed by students at Argentina’s La Universida­d Tecnológic­a Nacional (UTN);

• A space weather (radiation) instrument;

• An experiment titled “Marshmallo­ws in Space,” developed by the Oregon Museum of Science & Discovery to teach the scientific process to preschoole­rs.

• Two new environmen­tal sensors, developed by The Perlan Project.

The Perlan 2 will continue to pursue higher altitude flights and conduct research in the stratosphe­re as weather and winds permit through the middle of September.
