Retro Plane Invention of an aircraft is unarguably a milestone achievement in the history of humans. Science involved in the functioning of an aircraft existed long before the first humancontrolled, engine-powered flight took off in 1904, thanks to wright brothers. In this kit we are going to assemble a propeller driven aircraft model and explore the amazing concepts of flight dynamics.

How to operate: This is an exhibit and not a working model.
Lessons to be learnt: Let us first understand the three most important forces acting on an airplane. The first force is called the “Lift”. Just as the name suggests, Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Mostly, the wings are responsible to produce the lift, but only in a moving aircraft. The second force is the aerodynamic force that opposes an aircraft's motion through the air. This opposing force is called the “Drag”. The third force is the weight of the aircraft. This force is essentially the gravitational attraction of the earth on the airplane. For an airplane to fly, it must generate enough lift to oppose its weight. To generate lift, it must move through the air with good speed. However the motion of a the airplane through the air is opposed by the drag. This chicken and egg problem is resolved in a powered aircraft by the thrust from the engine. To summarize- “for a steadily flying airplane the engine needs to generate enough thrust to overcome the second force, “drag” and in-turn generate speed enough, to make the first force, “lift” big enough to overcome the third force, i.e. “weight” of the aircraft.” How to make paper glider? Take a thick paper, sketch the outline for a glider and cut out the wings. Attach it to a straw with the help of a rubber band (Observe the adjacent figure). Make sure the nose of the glider is made heavy. You can do this by attaching a heavy metal piece or an iron nail. Adjust the wings of the plane by making flaps on the wings either both up or both down or alternate up and down on the two wings. Observe and note down the difference in the flight of paper glider with the change in the arrangement of flaps on wings.
