longitudinal center of gravity
71aerodynamic forces — The forces on a body moving through a gaseous medium. In an aircraft, the thrust acts forward, drag acts rearward, and lift acts vertically upward. The weight of an aircraft produces a force that acts vertically downward. The tailplane also… …
72flat spin — A spin in which the aircraft longitudinal axis remains at less than 45° below the horizontal. A flat spin is a stabilized spin. The farther back the center of gravity and the more the masses that are distributed along the length of the fuselage,… …
73offset hinge — A helicopter main rotor hinge at a substantial distance from the axis of rotation. As compared with flapping hinges, offset flapping hinges provide better longitudinal and lateral stability and a wider center of gravity limits and permit the… …
74principal axis — i. The lateral, vertical, and longitudinal axes. ii. The axis of relative wind. iii. The principal inertial axis: that line passing through the center of gravity in a plane of symmetry about which a long, slender body tends to rotate when rolling …
75stabilions — Small winglike horizontal surfaces mounted on the aft fuselage of some airplanes to improve their longitudinal stability. Airplanes with a very large center of gravity range are the ones likely to have stabilions …
76Bicycle and motorcycle dynamics — A computer generated, simplified model of bike and rider demonstrating an uncontrolled right turn. An …
77Foucault pendulum vector diagrams — Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum. Diagrams are provided to illustrate a pendulum located at the North Pole, equator, and 45 degrees N to show how the rotation of Earth in relation… …
78Foucault Pendulum vector diagrams — Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum.Diagrams are provided to illustrate a pendulum located at the North Pole, equator, and 45 degrees N to show how the rotation of Earth in relation… …
79Insect wing — Original veins and wing posture of a dragonfly. Hoverflies hovering to mate …
80Titan (moon) — Titan Titan in 2005 by Cassini spacecraft Discovery Discovered by Christiaan Huygens …
