Airbus Perlan Mission II Soars to Over 62,000 Feet, Setting Second Altitude World Record and Crossing Armstrong Line
Airbus Perlan Mission II soars to over 62,000 feet, setting second altitude world record and crossing Armstrong Line EL CALAFATE, Argentina, 27 August, 2018 – 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. -
Analysis of Mountain Wave 3D Wind Fields in the Andes Derived From
Analysis of mountain wave 3D wind fields in the Andes derived from high-altitude sailplane flights Rick Millane1, Ni Zhang1, Einar Enevoldson2 and James Murray2 [email protected] 1Department of Electrical and Computer Engineering University of Canterbury, Christchurch, New Zealand 2NASA Armstrong Flight Research Center, Edwards, CA, USA Abstract Mountain lee waves are of importance in meteorology since they produce drag that affects the general circula- tion, and can influence windstorms, clear-air turbulence and ozone abundance. Since mountain waves are used routinely by sailplane pilots, data collected during wave flights are potentially useful for studying the structure of mountain waves. We have previously described methods for determining 3D wind velocities in mountain waves from limited sailplane flight data. These methods are applied to data from a high-altitude sailplane flight in the lee of the Andes that reached an altitude of over 15,000 m, well into the stratosphere, allowing a unique kind of in-situ observation of stratospheric mountain waves. The derived wind fields show parts of the wave structure in the troposphere and the stratosphere, and are compared with other observational data. Thus, a minimally instrumented sailplane can provide useful data for mountain wave research. Introduction from the mountain range.

Data Mining for Atmospheric Gravity Waves (Lee Waves)
Data Mining for Atmospheric Gravity Waves (Lee Waves) Alfred Ultsch1, Joachim Curtius2 and Christof Maul3 [email protected] 1Data Bionics Philipps-University Marburg, Marburg, Germany 2Institute of Atmospheric and Environmental Sciences Goethe-University Frankfurt, Frankfurt am Main, Germany 3Institute of Physical and Theoretical Chemistry Technische Universitat¨ Braunschweig, Braunschweig, Germany Abstract Gravity waves can emerge as a result of the perturbation of atmospheric circulatory systems. They encompass periodic, yet geographically stationary, changes in temperature, pressure and vertical wind component. Occur- rence of such waves is frequent if strong winds hit high mountains. Secondary effect of such waves may also be encountered as clear air turbulence (CAT) in commercial flights. Atmospheric gravity waves strongly influence weather phenomena and on a larger time scale climatic processes. They are responsible for the vertical transport and mixing of air from the stratosphere up to the mesosphere. First results from research flights in the Pyrenees during the spring 2015 measuring campaign are reported. Several flights with a sensor equipped unpowered glider in altitudes between 2000 and 7000m were undertaken. Data Mining and Knowledge Discovery methods were applied. The results point to interesting patterns (states) in the structure and formation of lee waves and lead to the understanding of such flights as Wave Track Flight scenarios.

While much is known in principle about lee waves (see [2]) there are several open issues. 2 g Acceleration of gravity, 9.81 m/s One of the most important points for the usability of lee waves h Altitude for efficient long distance gliding is the leeward distance of the FL Flight Level first upward lift from the wave generating obstacle. -
Airbus Perlan Project Mission II 2019 Season Stormi Noll, Desert Research Institute
Airbus Perlan Project Mission II 2019 Season Stormi Noll, Desert Research Institute The Airbus Perlan 2 research glider has recently returned from its 2019 campaign of using stratospheric waves and the polar vortex over the Southern Andes to reach record altitudes and collect scientific data. The Perlan Project is composed of a team of world-class scientists, engineers, pilots, and administrators working together to apply aerospace technology and atmospheric research to fly a glider higher than any unmanned aircraft has ever flown. The Perlan 2 currently holds several of the highest altitude records including the most recently attained record of 74,298 feet, set in September 2018. For the 2019 season, the Perlan set out to reach a record glider flight altitude of 90,000 feet. In addition to aeronautical advancement, the Perlan 2 also supports atmospheric scientific discovery by carrying an array of atmospheric instrumentation with the ability to measure temperature, ozone, UVA/UVB, atmospheric pressure, differential pressure, and wind speed, direction, and lift. The 2019 season was unique in that the southern polar region experienced an unprecedented sudden stratospheric warming event, which weakened the Perlan 2’s ability to reach record altitudes. A sudden stratospheric warming event is considered to be occurring when there is a sudden warming of the polar stratosphere without any obvious external source. These events can warm the polar stratosphere by as much as 10 degrees Celsius per day within a week, reversing the normal north-south temperature gradient that the polar jet requires to maintain strength. The polar night jet is believed to be a key driver of tropospheric weather and climate patterns. -

Segelfliegen in astronomischen Höhen! 1) Einführung Aufwind Wer erinnert sich nicht an seinen ersten „Tausender“: „Ich bin mit dem Segelflugmodell in der Thermik auf 1000m über Startstelle gestiegen!

Könnt Ihr das aber auch ohne Vario und in der Ebene?“ Wie hoch kommt man aber wirklich mit einem dafür optimierten Flugzeug, wenn als allerletzte und einzige Bedingung bleibt, dass es keinen Antrieb haben darf? Bis 8.000 m? Bis 10.000 m?

Prof. Filippo Maggi PhD. locations: Irvine, California Milano, Italia That you are here — that life exists and identity, That the powerful play goes on, and you may contribute a verse. — Walt Whitman, 1867 to my family ABSTRACT The gas turbine engine efficiency deteriorates dramatically when its size is reduced. This fact limits its use for low-power and long du- ration applications, due to fuel weight. It is conceivable to replace a small scale gas turbine engine with a different power generating tech- nology such as a Diesel engine providing higher efficiency. In this work, comparisons are made for propulsion systems for unmanned flights with several hundred kilowatts of propulsive power at mod- erate subsonic speeds up to fifty hours in duration. The weights of the propulsion system, required fuel, and total aircraft are consid- ered. Gas-turbine engines, two- and four-stroke reciprocating (diesel and spark-ignition) engines, and electric motors (with battery stor- age and/or electric generation) are analyzed. -
