Closeup view of a nose cone on a Boeing 737. Many references on nose cone design contain empirical data comparing the drag characteristics of various nose shapes in different flight regimes. The chart shown here seems to be the most comprehensive and useful compilation of data for the flight regime of greatest interest.
The approximate field of view of an individual human eye (measured from the fixation point, i.e., the point at which one's gaze is directed) varies by facial anatomy, but is typically 30° superior (up, limited by the brow), 45° nasal (limited by the nose), 70° inferior (down), and 100° temporal (towards the temple).
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
An aquiline nose (also called a Roman nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly bent. The word aquiline comes from the Latin word aquilinus ("eagle-like"), an allusion to the curved beak of an eagle.
ANB (A point, nasion, B point) indicates whether the skeletal relationship between the maxilla and mandible is a normal skeletal class I (+2 degrees), a skeletal Class II (+4 degrees or more), or skeletal class III (0 or negative) relationship.
Local tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation.
A reference model can represent the component parts of any consistent idea, from business functions to system components, as long as it represents a complete set. This frame of reference can then be used to communicate ideas clearly among members of the same community.
Jigglypuff appeared on the starboard nose of the original white 1998 aircraft and above the starboard wing of the 1999 blue aircraft. Jigglypuff was also on the nose of the international version of the plane. Jigglypuff has been made into several different toy and plush forms, as well as other items.
1958–1977. Number built. 23,839 [1] Variants. Cessna 152. The Cessna 150 is a two-seat tricycle gear general aviation airplane that was designed for flight training, touring and personal use. [2] In 1977, it was succeeded in production by the Cessna 152, a minor modification to the original design. The Cessna 150 is the fifth most produced ...
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.
