The presented work is focusing on the wind estimation and airframe identification based on real flight experiments as part of the SkyScanner project. The overall objective of this project is to estimate the local wind field in order to study the formation of cumulus-type clouds with a fleet of autonomous mini-UAVs involving many aspects including flight control and energy harvesting. For this p...

This paper reviews the interventions to stabilize calcium balance and bone metabolism and prevent bone loss in astronauts during space flight. Weightlessness during space flight results in calcium, vitamin D, and vitamin K deficiency, increases urinary calcium excretion, decreases intestinal calcium absorption, and increases serum calcium level, with decreased levels of serum parathyroid hormon...

Test and evaluation of flight vehicles play a significant role towards the successful validation of various design criteria of the flight vehicles. Analytical studies, design simulation, simulated performance validation with respect to various critical design parameters provide the basic level of design qualification. However, for the final validation of the flight vehicle performance, it requi...

Trajectory planning of multiple unmanned aerial vehicles (UAVs) is the basis for them to form formation flight. By considering trajectory UAVs in flight three-dimensional space, a method four-dimensional space-time proposed which, firstly, according configuration, adopts Hungarian algorithm optimize task allocation. Based on that, by safety formation, hierarchical decomposition innovatively put...

Flight capacity is important for invasive pests during entry, establishment and spreading. Both Bactroceradorsalis Hendel and Bactroceracorrecta Bezzi are invasive fruit flies but their flight capacities differ. Here, a tethered flight mill test demonstrated that B. dorsalis exhibits a greater flight capacity than B. correcta. RNA-Seq was used to determine the transcriptomic differences associa...

licorice, the oldest chinese traditional medicine, is widely used in the treatment of human diseases. due to the deficiency of wild resource, selecting and breeding becomes a key issue to expanding the supply of licorice. spaceflight technology will become a new method for medicinal plants. the aim of this study was to investigate the effect of spaceflight on the components and anti-inflammator...

We have followed the pupal development of the indirect flight muscles (IFMs) of Drosophila melanogaster. At the onset of metamorphosis larval muscles start to histolyze, with the exception of a specific set of thoracic muscles. Myoblasts surround these persisting larval muscles and begin the formation of one group of adult indirect flight muscles, the dorsal longitudinal muscles. We show that t...

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...
