 Stabilizing Rudder 



and machine fitted to insure proper shaft drive and housing support. 

 Light metal framework was used to support the television camera within 

 the pressure housing. 



To provide a minimum of turbulence and to equalize drag effects 

 at all camera housing attitudes while under tow a free-flooded ball 

 fairing was added to the cajnera housing (fig. 3). The ball fairing 

 was made of two interlocking hemispherical sections of I/I6" stainless 

 steel. The forward section was welded to li" x i;" x I/6" pads that 

 fitted over and were welded to cradle-shaft joints at each side. The 

 rear section of ball fairing was held in place with equally spaced 

 sheet metal screws which fastened it to the forward section. The rear 

 section being removable allowed access to inner framework and hold 

 dovm thumb screws. Ten inch circiilar holes padded with split rubber 

 hose were cut at each end of the ball fairing to provide access to the 

 camera through the rear seal plate and to give an opening for the 

 camera lens.
