71Gravity turn — A gravity turn or zero lift turn is a maneuver (see trajectory optimization) used in launching a spacecraft into, or descending from, an orbit around a celestial body such as a planet or a moon. This launch trajectory offers two main advantages… …
72Pitot tube — A Pitot (pronEng|ˈpiːtoʊ) tube is a pressure measurement instrument used to measure fluid flow velocity. The Pitot tube was invented by Italian born French engineer Henri Pitot in the early 1700s, and was modified to its modern form in the mid… …
73Max Q — For other uses, see Max Q (disambiguation). In aerospace engineering, the maximum dynamic pressure, often referred to as maximum Q or max Q, is the point at which aerodynamic stress on a vehicle in atmospheric flight is maximized. It is an… …
74navigation — navigational, adj. /nav i gay sheuhn/, n. 1. the act or process of navigating. 2. the art or science of plotting, ascertaining, or directing the course of a ship, aircraft, or guided missile. [1520 30; < L navigation (s. of navigatio) a voyage.… …
75Magnetopause — Artistic rendition of the Earth s magnetopause. The magnetopause is where the pressure from the solar wind and the planet s magnetic field are equal. The position of the Sun would be far to the left in this image The magnetopause is the abrupt… …
76Diving watch — Omega Seamaster model 2220.80, with a water resistance of 300 m (1,000 ft). The second crown (at 10 o clock) is a helium release valve. A diving watch is a watch designed for underwater diving that features, as a minimum, a water… …
77Lift coefficient — The lift coefficient ( or ) is a dimensionless coefficient that relates the lift generated by a lifting body, the dynamic pressure of the fluid flow around the body, and a reference area associated with the body. A lifting body is a foil or a… …
78Stagnation point — The stagnation point is a point on the surface of a body submerged in a fluid flow where the fluid velocity is zero. The Bernoulli equation shows that the static pressure is highest when the velocity is zero. The velocity is zero at stagnation… …
79Pitometer log — Pitometer logs (also known as pit logs) are devices used to measure a ship s speed relative to the water. They are used on both surface ships and submarines. Data from the pitometer log is usually fed directly into the ship s navigation… …
