Perlan II glider airplane in the mountain waves of Spring in Sierra Nevada

Minden, USA - Key improvements to the experimental aircraft destined to touch the space without engine

Airbus Perlan Mission II, an initiative to fly a glider without an engine to the edge of space to collect ground-breaking insights on high-altitude flight, weather, and climate change, returned to flight this week at its US headquarters at the Minden-Tahoe Airport. Perlan Project Pilots Jim Payne and Miguel Iturmendi soared the pressurized glider to its highest altitude to date, reaching 30,615 feet. The Perlan 2 will spend spring soaring in the rising wind currents –called mountain waves– in the skies above the Sierra Nevada, before deploying in May to Argentina for its second year of flight operations in Patagonia. To reach the altitudes that will enable the aircraft to conduct its unique research, the team is searching for elusive “stratospheric mountain waves", which only occur a few places on earth –such as Patagonia– and a few weeks out of the year. The Perlan Project‘s all-volunteer team has recently updated the experimental Perlan 2 glider, which features a pressurized cockpit, enhanced avionics and life support systems. Key improvements include: • Heating for critical items – Based on data collected during the first season of operations in Argentina, the team has installed additional heating to ensure that mission-critical systems such as the battery and the air and oxygen regulators are unaffected by the extreme cold temperatures at high altitude. • Control stick improvements – Modifications to the control sticks have been made to improve the pilot-to-aircraft interface. • Flight simulator updates – The team’s flight simulator has been upgraded to improve pilot training in preparation for high altitude flights.
