9/5/22 Simple Integration of the Hydrophone to the Front Vectored Thrusters

Colin Szeto

The thought process for this design is to integrate the hydrophone mounting onto the vectored front motor thrusters. This simplifies the design of the system as the propulsion superstructure can be utilized for the hydrophone mount. Greatest problem now is the proximity to the surface of the water

Rev 1, getting ideas down for a visual representation of the hydrophone mounting on the front vectored thruster’s vertical bar

Rev 2, top view, deciding where to place the hydrophone

Rev 3, determining the hydrophone should be under the interface plate to enable the greatest chance of the hydrophone receiving the pings

The blue dots represent the potential hydrophone placement location. 

The purple vectors represent the direction the water will flow. 

The hydrophone will be placed to the side of the motor mounts to avoid the currents that the motors will generate

The design is a single printed part with zip ties holding the hydrophone to the printed part

Parts count: 

1 AS-1 hydrophone

3 zip ties

2 ¼-20 1in long button head stainless steel screws

2 stainless steel t nuts

3d printed holder attached to the base plate

Biggest concern with this design is the hydrophone will most likely hit the trailer
