81Gravity 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… …
82Lift 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… …
83Kite control systems — Kite types, kite mooring, and kite applications result in a wide variety of kite control systems; contemporary manufacturers, kite athletes, kite pilots, scientists, and engineers are expanding kite control systems. Single line kite control… …
84Insect wing — Original veins and wing posture of a dragonfly. Hoverflies hovering to mate …
85airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also …
86Death of Ian Tomlinson — Ian Tomlinson redirects here. For the Australian athlete, see Ian Tomlinson (athlete). Death of Ian Tomlinson Ian Tomlinson remonstrates with police after being pushed to the ground, minutes before he died. Date 1 April 2009 ( …
87Dihedral (aircraft) — For other uses, see Dihedral. The upward tilt of the wings and tailplane of an aircraft, as seen on this Boeing 737, is called dihedral angle Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed wing aircraft.… …
88Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… …
89Stability derivatives — are a means of linearising the equations of motion of an atmospheric flight vehicle so that conventional control engineering methods may be applied to assess their stability.The dynamics of atmospheric flight vehicles is potentially very… …
90Kutta condition — The Kutta condition is a principle in steady flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies which have sharp corners such as the trailing edges of airfoils. It is named for German mathematician and aerodynamicist …
