upwash मीनिंग इन हिंदी

उदाहरण वाक्य

1. It's kind of an upwash that gives a neighboring bird a boost.
2. At the same time these vortices create an upwash that can aid the flight of following birds.
3. An upwash of air created by a leading bird allows a trailing bird to glide a bit longer, thus conserving energy.
4. This sideways influence ( upwash on the outboard, downwash on the inboard ) is the key to the lifting-line theory.
5. One theory on migrating bird flight states that many larger bird species fly in a V formation so that all but the leader bird can take advantage of the upwash part of the wingtip vortex of the bird ahead.
6. Studies of waldrapp ibis show that birds spatially coordinate the phase of wing flapping and show wingtip path coherence when flying in V positions, thus enabling them to maximally utilise the available energy of upwash over the entire flap cycle.
7. Now, if the " change " in lift distribution is known at given lift section, it is possible to predict how that section influences the lift over its neighbors : the vertical induced velocity ( upwash or downwash, \ omega _ i ) can be quantified using the velocity distribution within a vortex, and related to a change in effective angle of attack over neighboring sections.
