Rate descent, velocidad de descenso, ( Ingeniería aeroespacial ) Descenso de un avión desde altitudes superiores a un ritmo constante.

Rate gyroscope. ( Mechanical Engineering ) A gyroscope that is suspended in just one gimbal whose bearings form its output axis and which is restrained by a spring; rotation of the gyroscope frame about an axis perpendicular to both spin and output axes produces precession of the gimbal within the bearings proportional to the rate of rotation. Giroscopio angular, giroscopio para la medida de velocidades angulares (aviación). ( Ingeniería Mecánica ) . Un giroscopio que está suspendido en un balancín cuyos cojinetes están desalineados y limitados por un resorte; la rotación de la banca del giroscopio en relación a un eje perpendicular a los ejes de giro y salida produce una precedencia del balancín sin que los cojinetes guarden una velocidad de giro proporcional.

Rate integrating gyroscope. ( Mechanical Engineerting ) A single-degree-of-freedom gyro having primarily viscous restraint of its spin axis about the output axis; an output signal is produced by gimbal angular displacement, relative to the base, which is proportional to the integral of the angular rate of the base about the input axis. Giroscopio medidor de la velocidad angular , ( Ingeniería Mecánica ) Giroscopio de grado sencillo libre, que efectúa una retención viscosa de su eje de salida; se produce una señal de salida mediante un desplazamiento angular del balancín en relación a la base, lo cual es proporcional a la integral de la velocidad angular de la base en relación al eje de entrada.
