An ogive (/ˈv/ OH-jyve) is the roundly tapered end of a two-dimensional or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture and woodworking.



The earliest use of the word ogive is found in the 13th century sketchbook of Villard de Honnecourt, from Picardy in northern France. The OED considers the French term's origin obscure; it might come from the Late Latin obviata, the feminine perfect passive participle of obviare, meaning the one who has met or encountered the other.[1] However, Merriam-Webster's dictionary says it is from the "Middle English oggif stone comprising an arch, from Middle French augive, ogive diagonal arch".[2]

Types and use in applied physical science and engineeringEdit

In ballistics or aerodynamics, an ogive is a pointed, curved surface mainly used to form the approximately streamlined nose of a bullet or other projectile, reducing air resistance or the drag of air. In fact the French word ogive can be translated as "nose cone" or "warhead".

The traditional or secant ogive is a surface of revolution of the same curve that forms a Gothic arch; that is, a circular arc, of greater radius than the diameter of the cylindrical section ("shank"), is drawn from the edge of the shank until it intercepts the axis.

If this arc is drawn so that it meets the shank at zero angle (that is, the distance of the centre of the arc from the axis, plus the radius of the shank, equals the radius of the arc), then it is called a tangent or spitzer ogive. This is a very common ogive for high velocity (supersonic) rifle bullets.

The sharpness of this ogive is expressed by the ratio of its radius to the diameter of the cylinder; a value of one half being a hemispherical dome, and larger values being progressively more pointed. Values of 4 to 10 are commonly used in rifles, with 6 being the most common.[citation needed]

Another common ogive for bullets is the elliptical ogive. This is a curve very similar to the spitzer ogive, except that the circular arc is replaced by an ellipse defined in such a way that it meets the axis at exactly 90°. This gives a somewhat rounded nose regardless of the sharpness ratio. An elliptical ogive is normally described in terms of the ratio of the length of the ogive to the diameter of the shank. A ratio of one half would be, once again, a hemisphere. Values close to 1 are common in practice. Elliptical ogives are mainly used in pistol bullets.

Missiles and aircraft generally have much more complex ogives, such as the von Kármán ogive.

One of the defining characteristics of Gothic architecture is the pointed or ogival arch. Archaeological excavation conducted by Archaeological Survey of India (ASI) at Kausambi revealed a palace with its foundations going back to 8th century BCE until 2nd century CE and built in six phases. The last phase dated to 1st - 2nd century CE featured an extensive structure which features like four centered pointed arch which was used to span narrow passageways and segmental arch for wider areas.[3]

In the Middle East, the pointed arch as an architectonic principle was first clearly established in Islamic architecture. As an architectonic principle, it has been claimed that the pointed arch is completely alien to the pre-Islamic world from the Middle East.[4] Arches resembling the shape similar to pointed arches have been used in Buddhist architecture since ancient times. The 1st century AD Buddhist complex of Takht-e-bahi prominently features corbel arches which are shaped like lotus leaves.[citation needed] An ancient 4th-century Buddhist brick Chaytiya temple and Trivikrama temple in Maharashtra also exhibits ogival arches. It is argued by some scholars that pointed arches were used in the Near East in pre-Islamic architecture,[5] but others have argued that these arches were, in fact, parabolic and not pointed arches,[6] which were first introduced during Abbasid period from either India or Central Asia in the Islamic architecture before they were employed structurally in medieval architecture, and are thought to have been the inspiration for their use in Sicily and France; as at Autun Cathedral, which is otherwise stylistically Romanesque.[7]

In Gothic architecture, ogives are the intersecting transverse ribs of arches which establish the surface of a Gothic vault. An ogive or ogival arch is a pointed, "Gothic" arch, drawn with compasses as outlined above, or with arcs of an ellipse as described. A very narrow, steeply pointed ogive arch is sometimes called a "lancet arch". The most common form is an equilateral arch, where the radius is the same as the width. In the later Flamboyant Gothic style, an "ogee arch", an arch with a pointed head, like S-shaped curves, became prevalent.


In glaciology, the term ogives refers to alternating bands of light and dark coloured ice that occur as a result of glaciers moving through an icefall.[citation needed]
