Dihedral angle
| Глоссарий авиационных и аэрокосмических терминов |
The angle that an aeroplane’s wings make relative to the lateral axis (horizontal plane, when on level ground). a larger dihedral angle gives greater roll(lateral) stability at the cost of efficiency. if the wings angle upwards, it is called the dihedral angle. downward angled wings are said to have an anhedral angle (increasingly referred to as negative dihedral).

Angle, английский
- Угол
- The space or aperture intersected by the natural inclination of two lines or planes meeting each other, the place of intersection being called the vertex or angular point, and the lines legs. angles are distinguished by the number of degrees they subtend, to 360°, or the whole circumference of a circle. angles are acute, obtuse, right, curvilinear, rectilinear, &c. (all of which see).

- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a
