For the Navy and an artillery shell casing

(5) I have a proposal for a propeller that has a guide consisting of metal or composite materials, a nozzle that is rigidly attached to the propeller blades and rotates simultaneously with it. The propeller blades have a fixed and gradually increasing pitch. Firmly seated, the guide nozzle-the nozzle has a conical form. This propeller will be more efficient, quieter in operation, will not wind ropes on the blades and everything like that, and most likely there will be less cavitation. All this is suitable for the "Azipod" mechanism, an approximate sketch is attached.

(10)I suggest a way to fire a rocket or unguided rocket projectile from the barrel of a gun, using an artillery shell that is rotated 180 degrees and the size that corresponds to the diameter of the gun barrel. The cartridge case leaves the gun barrel with the projectile and separates after departure from the gun barrel. This will give additional speed and increase the range of the projectile or missile.
