330-PS-48 (USN 707453):   Navy’s New Flight Simulator.   The calculating machines, known as flight simulator, involves the use of intricate computing machines and a “flight table” on which actual problems relating to flight stability are worked out.  The table (shown above) is an arrangement of gimbals, delicately suspended so that they can incline freely in any direction.  A similar (gimbal) principle is used on shipboard to permit a compass to remain level.   The gimbal table is used to orient the automatic control system of a theoretical plane or missile just as it would be tested in actual flight.  It rolls, pitches, and comes through all the motions the plane would make in the air under stated conditions.  The motions of the table, representing the actions of the hypothetical plane or rocket in flight are recorded on charts, and are visually studied by test engineers, January 29, 1950.  (8/18/2015).
