OBJECTIVES

Weaker standing waves exist beyond the tropopause in the stratosphere. The Perlan Project was conceived by former NASA test pilot Einar Enevoldson to demonstrate the feasibility of riding these stratospheric standing waves to even greater altitudes and thereby break the record. However the weather necessary to climb into the stratospheric waves are quite exceptional:
  • The Polar Vortex overhead (occurring only in near-polar latitudes during winter)

  • Prefrontal conditions

  • A weak tropopause

  • A gradual increase in windspeed with altitude

  • Wind direction within 30° of perpendicular to the mountain ridgeline

  • Cooperation of any present subtropical jet stream

  • Strong low-altitude winds in a stable atmosphere

  • Ridgetop winds of at least 20 knots


Phase one of the project, a proof of concept flight, has a goal of 62,000 feet (18,900 meters). Phase two, which will probably be attempted with a custom-built glider, has a goal of 100,000 feet (30,480 meters).


PROGRESS

The project was based for a few years in Omarama , New Zealand , but it is currently based in Patagonia , at El Calafate , Argentina .

The glider is currently a modified DG Flugzeugbau 505M two-seater sailplane from which the motor has been removed to make room for batteries and liquid oxygen. The pilots are Steve Fossett and Einar Enevoldson and are equipped with full pressure suits.


PRESS RELEASE FOR AUGUST 29, 2006

"Into the Stratosphere – Without an Engine
New world glider altitude record set by Fossett and Enevoldson in Argentina
50,671 feet (15,447 m) achieved by 'Perlan' - the first ever glider flight into the earth's stratosphere. Previous record shattered by 1,662 ft (507 m)". Perlan Project's Website (This claim subsequently ratified by Federation Aeronautique Internationale as 15,460 meters (50,727 feet).
