Bronco Type XXIII Torpedo Door Mechanism

For those not on Facebook.

Tomio Sugiura-san's Type XXIII torpedo door mechanism based off of Bob's illustration.

Instead of using an articulated Y-joint connecting both doors to the servo rod Tomio used 2 thin flexible rods directely connected to the doors and actuating servo. When the servo retracts the rods the guide sleeve squeezes the rods pulling the doors together.

Pretty much the same system i did on the XXI, only disadvantage, you open both doors at the same time.
On my XXIII i can open the doors seperatly from each other, so you can shoot the torps one by one.

Just a matter of using a double arm servo horn to pull on the torpedo doors. A spring or opposite pole magnets on the inside of the doors automatically keeps them shut.

Romel,

Using a double servo arm creates other issue's, when pulling on one door you have to push on the other door, so you have to design a mechanism to counter that.
Using opposing magnets to keep the doors shut will work, but when you fire electric torpodo's they will stop running when they go by the doors, a nightmare for the uboot captain, limping home with two torps halfway out of your tubes, that should be fun.

1. Control rod sliding through a Dubro EZ connector.
wheel collar at end of control rod Catches on ez connector during pull but slips forward. .
