McDonnell Douglas ha_ changed the stage to a workshop configuration
by _nstalling crew quarters floors and other _artitions. Actual or
simulated equipment has been used to give the model the same mass and
dynamic characteristics as a flight version.
At MSC, the highly iastrumented vehicle will first be placed in an
acoustic chamber and subjected %o sound waves which simulate the Saturn V
launch acoustic environment. After a series of tests at different sound
intensities_ it will be moved to another chamber and connected to electromagnetic
"shakers" which will simulate elements of the launch e_vironment
such as vibration.
The test program at MSC is to last from about the end of Jan. to
the middle of May_ 1971.
Yollow_ng those tes{s_ the vehicle will be moved to the Marshall
Space Flight Center where static load testing will be done _n MSFC's
Astronautics Laboratory. Leads placed on _he vehicle will simulate the
forces which the main structural elements of the workshop will encounter
prior to launch and durin{[ launch and orbital flight.
The Marshall Center directs the worksboe development program.
