What makes an aeroplane fly kids

Joe Ruhl has shared the joys of science with students for 35 years. This is this month's science question, which will publish the last Wednesday of each month. The air pushes the planes up and hard. It glides with the air. That is the way to make the planes fly. The gas that comes out of the bottom of the plane and the people that fly it helps it to stay in the air. The way airplanes stay in the sky is millions of bees are under the airplane helping them get to their destination.

They stay in the sky because little people that can fly hold them up and the little people eat jelly and poop out gas. When the jet is on the ground, they push a button and the jet engine starts working.

It blows smoke and the jet engine on the back helps it soar into the sky. Airplanes stay in the air because there is a person in it that is by the engine that blows into it to keep it in the air. That guy probably gets tired after a while!

I think a nice witch makes a special potion. Every time an airplane is ready to take off, she throws the magical potion at the last second and makes the plain fly. Airplanes stay in the sky because of the things at the back.

In the front, someone has to drive it. There's no spaces through it. When wind blows it can still fly through the wind. And what it is made from and the control buttons. The air pushes the plane and the wings so the plane can fly. The engines, and the propellers, and the wings allow it to fly.

The airplane engine pushes air to the propeller and the propeller pushed air to the wings. The wings are both built to be the same weight, the same length, and shape: it helps it stay balanced. The wings have to be a little bit towards the front of the plane so it doesn't fall one way or the other because the heavier stuff in the plane is in the front and the lighter stuff is in the back of the plane.

When the air pushes the plane its built where it's like it cuts the air and gets through quicker. That is how an airplane stays in the sky. The airplanes stay in the sky by getting full of gas and not crashing into anything and good speed. The pilot controls the engine power using the throttle. Pushing the throttle increases power, and pulling it decreases power.

The ailerons raise and lower the wings. The pilot controls the roll of the plane by raising one aileron or the other with a control wheel. Turning the control wheel clockwise raises the right aileron and lowers the left aileron, which rolls the aircraft to the right. The rudder works to control the yaw of the plane. The pilot moves rudder left and right, with left and right pedals. Pressing the right rudder pedal moves the rudder to the right.

This yaws the aircraft to the right. Used together, the rudder and the ailerons are used to turn the plane. The elevators which are on the tail section are used to control the pitch of the plane. A pilot uses a control wheel to raise and lower the elevators, by moving it forward to back ward.

Lowering the elevators makes the plane nose go down and allows the plane to go down. By raising the elevators the pilot can make the plane go up. The pilot of the plane pushes the top of the rudder pedals to use the brakes. The brakes are used when the plane is on the ground to slow down the plane and get ready for stopping it. The top of the left rudder controls the left brake and the top of the right pedal controls the right brake.

If you look at these motions together you can see that each type of motion helps control the direction and level of the plane when it is flying. Sound is made up of molecules of air that move. They push together and gather together to form sound waves. Sound waves travel at the speed of about mph at sea level.

When a plane travels the speed of sound the air waves gather together and compress the air in front of the plane to keep it from moving forward. This compression causes a shockwave to form in front of the plane.

In order to travel faster than the speed of sound the plane needs to be able to break through the shock wave. When the airplane moves through the waves, it is makes the sound waves spread out and this creates a loud noise or sonic boom. Beginners guide to aerodynamics. Lots of different paper airplanes.

Websites with information on flight Beginners guide to aerodynamics. Lift is generated by the forward motion of the airplane through the air. This motion is produced by the Thrust of the engine s.

Drag is the force produced by the resistance of the air to the forward motion of the airplane. Swish your hand rapidly side-to-side and you will feel that resistance on your hand. Weight is the force created by the pull of gravity toward the center of the earth. You will feel the effect of this force if you jump up from the floor. Your weight will force you back down. When the Thrust produced by the engine s is greater than the force of Drag , the airplane moves forward.

When the forward motion is enough to produce a force of Lift that is greater than the Weight , the airplane moves upward. Governor Ned Lamont.
