And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Why, it's defying physics, using Bernoulli's wing lift principle.
Bernoulli's wing lift principle states that when air flows over a curved wing surface, the air moving faster over the top of the wing creates a lower pressure compared to the slower air moving under the wing, resulting in an upward lifting force on the wing due to this pressure difference; essentially, faster moving air creates lower pressure, causing the wing to lift. Key points about Bernoulli's wing lift principle: Airfoil shape: Airplane wings are designed with a curved upper surface and a flatter bottom surface, forcing air to travel faster over the top than the bottom. Pressure difference: The faster moving air on top creates a lower pressure area, while the slower air underneath generates a higher pressure area. Lift force: This pressure difference between the top and bottom of the wing results in an upward lifting force.
The key is the angle of attack. The plane is pitched upwards so the air hits the wing well aft of the leading edge but on the top (not bottom) so lift is generated the other way.
I did hang gliding for about 5 years but turbulence and nausea finally defeated me. When the wind was steady, even and forceful I had many a launch identical to this raptor. Walk slowly to the edge and then straight up and away.

Nicely done...

ReplyDeleteOkay, now explain inverted flight.

ReplyDeleteFrom experience Bio Jesus will do the same thing…
