"Webbrecommended. Fighter aircraft are often equipped with all moving horizontal tail to create the maximum amount of pitching moment in order to improve the pitch maneuverability. Most fighter aircraft have such tail, since they are required to be highly maneuverable. Table 12.18 shows specifications of elevators for several aircraft. " - Pitching of aircraft

WebbAircraft trim is an adjustment to the control surfaces. Better said, we can replace the word trim with “adjust” and get a similar meaning. When we “trim” an aircraft, we are adjusting one or more of the movable control surfaces so that the pilot doesn’t need to hold them with physical strength and can focus elsewhere. WebbBy also adjusting the pitch angle of each main rotor blade they deflect air downwards which aids in the control of the aircraft from the pilot. To create this lift the helicopter’s main rotor system can consist of 2,3,4,5,6 or even 8 main rotorblades that work as a whole when being rotated by the engine.

Webb2 nov. 2012 · The greatest effect on pitching moment arises from the tailplane. The effectiveness of the tailplane is enhanced simply because of increased flow velocity and reduced downwash angle. These two effects together increase the nose-down pitching moment available and hence increase the degree of stability of the aircraft. http://www.diva-portal.org/smash/get/diva2:1380845/FULLTEXT01.pdf
