Early Rocket Liftoff

High  velocity  gas  flow     intense  noise  

Impinging  intense  noise  results  in  random  skin  vibra7on,  re-­‐radiated  internally  as  intense  interior  noise  and  results  in  intense  random  vibra7on  responses,  especially  of  thin  sec7ons  such  as  wiring  boards.    

Our  first  serious  recogni7on  of  random  vibra7on  as  an    engineering  problem  was  in  the  early  1950s,  when  many  rockets  exploded  at  igni7on  or  exploded    or  went  out  of  control  during  liToff.
