As the saying goes, there is no such thing as a free lunch-and lift has costs. One of them is wingtip vortices. If you're the only airplane on the planet, you have nothing to worry about. Here, you're ...

By far the most popular explanation of lift is Bernoulli’s theorem, a principle identified by Swiss mathematician Daniel Bernoulli in his 1738 treatise, Hydrodynamica.

That tendency can be used to increase the lift created by an airplane wing if the exhaust is deflected downward by the wing’s trailing edge.

The development team of Lilium created a new experimental aircraft 'Phoenix 2' and conducted an experiment to switch from hover flight to 'fly using lift' similar to a general airplane during flight.
