  • Description

    A machine that simulates the motion of a ship at sea is being used in studies for the U.S. Navy determine how the heave and roll affects the performance of the man who operates sonar equipment. Sonar is used to listen for and locate submarines.

    There's nothing wrong with the camera shooting this film. It's mounted on the machine that matches the motion of the ship in a heavy sea. Scientists of the Boeing Company in Seattle, Washington, built the rig to conduct tests for the Navy. The equipment simulates the sea so realistically that several Boeing employees who volunteered for the tests have developed advanced cases of seasickness. Others, however, enjoyed riding the "lab-lockef seahorse". The employee volunteer normally works in a hood, to simulate the darkness of the sonar room aboard ship. Electronic controls move him and his sonar scope in independent horizontal and vertical directions. Recording equipment monitor his work to see how well he performs.

    The motion machine consists of an operator's station, enclosed by a black canopy, mounted atop an arched 20-foot runaway. During a test, the station rolls from side to side over the runaway while, at same time, the entire runaway structure rises and falls along a vertical track. The equipment is controlled by random electrical impulses, and neither the test subject nor the test operators know before hand what the pattern of movement will be.
