Lonely helicopter

By Brady, Serena, and Briley

Aerial screw

Leonardo Da vinci's aerial screw was an idea that helped develop the helicopter.

Enginnering

Our helicopter consists of four wings with two blades each alternating independently that connects in the middle of the aircraft and is solar powered.


Though the first actual helicopter was not built until the 1940s, it is believed that Leonardo Da Vinci’s sketches from the late fifteenth century were the predecessor to modern day flaying machine.

As with many of Da Vinci’s ideas, he never actually built and tested it- but his notes and drawings mapped out exactly how the device would operate.

Significance

This aircraft will lead to much less pollution for travel and can also just be for enjoyment. This is needed as an alternative to driving. Step forward in more solar powered technology.

Science

Thrust-a reaction force described quantitatively by Newton's second and third laws. When a system expels or accelerates mass in one direction the accelerated mass will cause a proportional but opposite force on that system.

Lift-Upward-acting force on an aircraft wing or airfoil. An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force.

Drag- a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
