pitching moment उदाहरण वाक्य
उदाहरण वाक्य
- Because it involves a moving balanced surface, a stabilator can allow the pilot to generate a given pitching moment with a lower control force.
- The pitching moment is, by convention, considered to be positive when it acts to pitch the airfoil in the nose-up direction.
- Conventional cambered airfoils supported at the aerodynamic center pitch nose-down so the " pitching moment coefficient " of these airfoils is negative.
- Most notably, the pitching moment being zero puts a constraint on the longitudinal motion of the aircraft that can be used to determine the elevator control input.
- This means that any disturbance ( such as a gust ) which raises the nose produces a nose-up pitching moment which tends to raise the nose further.
- This is a single value of \ alpha, for a given aircraft configuration, where there is no pitching moment, i . e . a trim point.
- An alternative is the use of low or null pitching moment airfoils, seen for example in the Fauvel and Marske Aircraft series of sailplanes, have used it.
- This airfoil section was chosen because it has zero pitching moment, which thus allows moderate torsional loads despite the resulting glider's relatively large wing area of.
- The chord of the airfoil, to compute a pitching moment coefficient, this coefficient changes only a little over the operating range of angle of attack of the airfoil.
- If an aircraft is longitudinally stable, a small increase in angle of attack will cause the pitching moment on the aircraft to change so that the angle of attack decreases.
