PARASOL in-flight calibration and performance [PDF]
Applied Optics, 2007 Since 18 December 2004, the PARASOL satellite is a member of the so-called A-train atmospheric orbital observatory, flying together with Aqua, Aura, CALIPSO, CLOUDSAT, and OCO satellites. These satellites combine for the first time a full suite of instruments for observing aerosols and clouds, using passive radiometer complementarily with active lidar ...

Three-Dimensional Flight Envelope for V/STOL Aircraft with Multiple Flight Modes
Aerospace, 2022 Vertical or short take-off and landing (V/STOL) aircraft generally have three flight modes, namely, vertical take-off and landing (VTOL), conversion, and cruise, according to the variable angle of propulsion direction to the fuselage axis.

Resolution of a paradox: Hummingbird flight at high elevation does not come without a cost [PDF]
, 2004 Flight at high elevation is energetically demanding because of parallel reductions in air density and oxygen availability. The hovering flight of hummingbirds is one of the most energetically expensive forms of animal locomotion, but hummingbirds are ...

Curving to Fly: Synthetic Adaptation Unveils Optimal Flight Performance of Whirling Fruits. [PDF]
Physical Review Letters, 2019 Appendages of seeds, fruits, and other diaspores (dispersal units) are essential for their wind dispersal, as they act as wings and enable them to fly. Whirling fruits generate an autogyrating motion from their sepals, a leaflike structure, which curve ...
