C. Assembly of the Housing 



18. After calibration, the can is slid over the stack — guiding 

 the cable from the bottom of the can into a large cut-out on the 

 outer edge of the wafers. 



19. When the can's cable reaches the transducer stack's 

 electrical connector, the two are mated and the can is secured to 

 the end-cap. 



20. The can is then slid into the bottom of the fuselage, sensors 

 first. The arm sensors are guided out the four large fuselage 

 holes and the can pushed upwards until it hits the stops inside 

 the fuselage. 



21. The bottom stops are then screwed into the fuselage walls to 

 secure the can. 



22. This assembly is then stood up on blocks (to protect the 

 titanium bolts on the underside of the fuselage). 



23. The PVC spider is pushed in through the top of the fuselage 

 until it lines up with the arm-holes. The PVC arms are pushed 

 through the fuselage walls and into the spider. They are secured 

 by bolts that thread through the top of the spider.
