The three axes of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.
The pitch axis (also called transverse or lateral axis), [5] passes through an aircraft from wingtip to wingtip. Rotation about this axis is called pitch . Pitch changes the vertical direction that the aircraft's nose is pointing (a positive pitching motion raises the nose of the aircraft and lowers the tail).
Blade pitch acts much like the gearing of the final drive of a car. Low pitch yields good low speed acceleration (and climb rate in an aircraft) while high pitch optimizes high speed performance and fuel economy. It is quite common for an aircraft to be designed with a variable-pitch propeller, to give maximum thrust over a larger speed range ...
The longitudinal stability of an aircraft, also called pitch stability, [2] refers to the aircraft's stability in its plane of symmetry [2] about the lateral axis (the axis along the wingspan). [1] It is an important aspect of the handling qualities of the aircraft, and one of the main factors determining the ease with which the pilot is able ...
Elevator – is a flight control surface, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. Elliptic partial differential equation –
Pitching moment coefficient is fundamental to the definition of aerodynamic center of an airfoil. The aerodynamic center is defined to be the point on the chord line of the airfoil at which the pitching moment coefficient does not vary with angle of attack, [ 1 ] : Section 5.10 or at least does not vary significantly over the operating range of ...
Yaw, pitch and roll in an aircraft Yaw motion in an aircraft Mnemonics to remember angle names A yaw rotation is a movement around the yaw axis of a rigid body that changes the direction it is pointing, to the left or right of its direction of motion.
Pitch angle (kinematics), the rotation about the transverse axis of a stiff body Pitch angle (aviation), an airplane's rotation about its transverse axis; Pitch angle (ship motion), a ship's rotation about its transverse axis; Pitch angle of a spiral, the angle between a spiral and a circle with the same center
