Why DOEs a paper helicopter fall slowly or quickly?
In this position, the air under one blade is pushing one way and the air under the other blade is pushing the opposite way. These two forces of air push the blades around and make it spin. The faster the blades spin, the less the air can get by, and the slower the helicopter falls.
What is a paper Robocopter?
A robocopter is a paper construction that spins as it falls when it is dropped from a height. Your task is to make a robocopter and then investigate how changing one variable or factor affects the time that it takes to fall.
Why do Roto copters spin?
Why does the Roto-Copter spin? When the Roto-Copter falls, air pushes up against the blades, bending them up just a little. When air pushes upward on the slanted blade, some of that thrust becomes a sideways, or horizontal, push. The two opposing thrusts work together to cause the toy to spin.
How do you make a Mars helicopter?
It’s all part of the design process.
- Cut out the helicopter. Cut along the dashed lines of the template.
- Fold along the solid lines. The propeller blades, A and B, should be folded in opposite directions along the solid lines.
- Do a test flight.
- Compare.
- Experiment.
- Make a new model.
- Reverse it.
- Count the rotations.
How do you make a paper Helicopter template?
Cut a strip of paper 2 inches x 8 1/2 inches. Make a vertical cut 2 1/2 inches long into the rectangle. Then fold the rotor blades, one forward and one back. Make 1/2 inch cuts horizontally, about 1 1/4 inch below the rotor blades. Fold the sides of the body in along those 1/2 inch folds.
How are paper Helicopters kept in the air?
Gravity is the force pulling the paper helicopter to the ground. As the helicopter drops, the air pushes up against the blades, causing them to rotate. In doing so they create lift which helps to keep the helicopter in the air. The direction the blades are bent in will affect whether it spins clockwise or anti-clockwise.
Why do paperclips make a helicopter fall faster?
The direction the blades are bent in will affect whether it spins clockwise or anti-clockwise. Adding more weight (paperclips) will make the helicopter fall faster. PAPER HELICOPTERS How can we make a helicopter out of paper?
How are the blades folded on a helicopter?
The propeller blades, A and B, should be folded in opposite directions along the solid lines. The X and Y panels fold toward the center, and Z is folded upward to give the body of the helicopter rigidity and lower its center of gravity for more stable flight.
