Midget Submarine Propulsion Systems

Midget Submarine Propulsion Systems

 

SPS Drives – Low RPM…. Permanent
Magnet…. Brushless DC Propulsion Drives

Midget Submarines and larger underwater platforms are force enhancers as they significantly increase Naval mobility and effectiveness while reducing detection. These vehicles need power plants with low magnetic signatures and minefield stealth; minimum interference with navigational, search and other equipment; and operator safety and comfort.

Single Propeller/Single Winging Design (S)

The unit uses a single motor on the drive shaft with no reduction gears (Quiet Operation), feedback device and the Motor Control, sensors and electronics in a single integrated housing – The unit will accept nominal AC and/or DC input power and a speed control command to provide shaft output at the commanded rotational speed

 

Single Propeller/Dual Winging Designs (D)

The unit uses dual redundant (2) motors on a common shaft, two feedback devices and two sets of Motor Controls, sensors and electronics in a single integrated housing – complete “get home capability”. The unit will accept nominal input power and a speed control command to provide shaft output at the commanded rotational speed.

Dual Propeller – Counter Rotating Propulsion Modules for Stealth “Silent” Operation

Approximately 18% more thrust and …the counter rotation design assures that no gyroscopic moments are transferred to the vehicle. Very fast response times are assured with “Silent and Vibration Free Operation”.

The unit will be dual redundant with two motors on a common shaft, two feedback devices and two sets of Motor Control (MC), sensors and electronics in a single integrated housing. The unit will accept nominal input power and a speed control command to provide shaft output at the commanded rotational speed. Serial interfaces (optional) will be available for monitoring operation of the unit.

Subsea vehicles need power plants with low magnetic signatures and minefield stealth; minimum interference with navigational, search and other equipment; and operator safety and comfort.

The propulsion system consists of electric motors, controllers and batteries and distribution conductors. Magnetic fields emitted from these components pose a serious threat of magnetic mine activation. In addition, these fields interfere with navigational and magnetic search missions and raise operational safety and comfort issues. Also magnetic emissions provide observable (and therefore undesirable) signature components and reduce the overall system stealth.

Existing Systems can be retrofitted with an advanced shielding system and experience a significant reduction in magnetic field signature. Based upon experience and initial estimates, a magnetic reduction of greater than 20dB is probable by retrofitting a signature reduction system.
