thor Posted August 28, 2018 Share Posted August 28, 2018 It works out that 1kt is about 100ft/min. Actually 101ft/min. Link to comment Share on other sites More sharing options...
Guest Posted August 28, 2018 Share Posted August 28, 2018 Perhaps the air tank is used to maintan the cabin pressurization? Perlan 2, benefitting from the lessons learned on Perlan 1’s ascent, incorporates a pressurized cabin to allow its pilots to enjoy unencumbered flight, with full control over stick and rudder, and many small switches. The cabin pressure of 8.5 pounds per square inch (psi) gives a cabin atmosphere equal to flight at about 14,000 feet. With an empty weight of 1,500 pounds, and a wing area of 262 square feet, the 84-foot span machine is amazingly light for the structural strength required for stratospheric flight.
