Glossary term Aerodynamic Drag The resistive force exerted by air or another gas on a body moving relative to the flow. Glossary term Center of Pressure The point on a body or surface where the resultant pressure force can be considered to act for an equivalent net force and moment. Glossary term Gyroscope A device or sensor that measures angular rate or maintains orientation using rotational dynamics. Glossary term Jet Engine Cycle The thermodynamic cycle that converts fuel energy and airflow into thrust in gas turbine jet engines. Glossary term Lift Coefficient A dimensionless coefficient relating aerodynamic lift force to dynamic pressure and reference area. Glossary term Mach Number A dimensionless ratio comparing object or flow speed with the local speed of sound in the surrounding medium. Glossary term Thrust A propulsive force generated by accelerating mass or interacting with a surrounding fluid. Glossary term Vortex Shedding The periodic release of alternating vortices behind a bluff body, often causing oscillating forces and flow-induced vibration. Glossary term Wake The disturbed flow region downstream of a body moving through or immersed in a fluid. Glossary term Wind Tunnel A test facility that produces controlled airflow around models, vehicles, components, or specimens for aerodynamic measurement. Glossary term Xenon Ion Thruster An electric propulsion device that ionizes xenon and accelerates the ions to produce spacecraft thrust. Glossary term Yaw Angle The rotation angle of a body about its vertical or body-z axis relative to a defined reference direction. Glossary term Yaw Rate The angular velocity of a vehicle or body rotating about its vertical or body-z axis, used in stability and navigation control.
