However, with only a hydrostat controlling the depth fins in a negative feedback loop, the torpedo tends to oscillate around the desired depth rather than settling to the desired depth. The addition of a pendulum allows the torpedo to sense the pitch of the torpedo. The pitch information is combined with the depth information to set the torpedo ...
Figure 2: Illustration of general torpedo fire-control problem. A straight-running torpedo has a gyroscope-based control system that ensures that the torpedo will run a straight course. [26] The torpedo can run on a course different from that of the submarine by adjusting a parameter called the gyro angle, which sets the course of the torpedo ...
Control surfaces are essential for a torpedo to maintain its course and depth. A homing torpedo also needs to be able to outmaneuver a target. Good hydrodynamics are needed for it to attain high speed efficiently and also to give a long range since the torpedo has limited stored energy.
The Mark 44 torpedo is a now-obsolete air-launched and ship-launched lightweight torpedo manufactured in the United States, and under licence in Canada, France, Italy, Japan and the United Kingdom, with 10,500 being produced for U.S. service. It was superseded by the Mark 46 torpedo, beginning in the late 1960s.
After hearing of the deep-running torpedo problem, most submarine skippers simply set their torpedoes' running depth to zero, [54] which risked the torpedo broaching the surface. Torpedo depth is a control problem; good depth control requires more than just measuring the torpedo's depth. A depth control system that used just depth (measured by ...
Mark 10 torpedoes, and those developed at the same time (Mark 9 air- and Mark 8 surface ship-launched) used essentially the same control package (the Ulan gear [clarification needed]) as the newer Mark 14 for depth and direction. [citation needed] The running depth could be set to between 5 and 35 m (16 and 115 ft).
The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction [3] in 1960, [citation needed] and is in use aboard the warships of several other navies. [3]
Mk-48 and Mk-48 ADCAP torpedoes can be guided from a submarine by wires attached to the torpedo. They can also use their own active or passive sensors to execute programmed target search, acquisition, and attack procedures. The torpedo is designed to detonate under the keel of a surface ship, breaking the keel and destroying its structural ...
