Motions of an aircraft

Posted by yognasticization Friday, January 1, 2010



In our 3-dimensional world, an aircraft has three degrees of freedom.  It is very important to make an overview of these three degrees of freedom to understand the stability and control of an aircraft. An aircraft rotates about its center of gravity (c.g). The center of gravity of any object is a point in the middle of the mass where the mass is balanced.  It can be seen from the following examples:








The mass on each of the sides of these objects is equal. In other words, he object is in equilibrium when the object is supported at the point of cg.
 
 


  


Aircraft Roll Motion:
A roll motion is an up and down movement of the wings of the aircraft as shown in the picture hereby. This type of motion is used to change the direction of an aircraft during flight. For an aircraft to be rolled, ailerons’ are used at the rear section of the wings. The movement of ailerons cause the aircraft to roll.

 Aircraft Pitching Motion:
A pitch motion is an up or down movement of the nose of the fuselage of the aircraft as shown in the picture hereby. This type of motion is used to change the altitude of an aircraft during flight. For an aircraft to be pitched, elevators are used at the rear section of the horizontal stabilizer. The movement of elevators up or down cause the aircraft to pitch.

Aircraft Yawing Motion:
A yaw motion is a side to side movement of the nose of an aircraft during flight. This can be seen clearly in the picture below. This type is motion is vital for changing the direction or rotating the aircraft. Rudders located at the vertical stabilizers are used for yawing motions in an aircraft.
