On 22 AugustBdU Befehlshaber der U-BooteU-Boat High Command directed a query to TVA TorpedoversuchsanstaltTorpedo Experimental Stationif G7a T I wet-heater torpedo could be modified in such way that after travelling the pre-set distance, it would start to circle with diameter of — meters. This query resulted from the idea that in the case when torpedo missed the target in convoy, the remaining torpedo run could be utilized to circle inside the convoythus creating the another chance for hit. For instance, the G7a wet-heater torpedo with the maximum running distance of meters at 30 knotslaunched to the target meters away, after missing, run for another 10 km. If it started to circle after missing the target with diameter of — meters, it would make 3 — 2 rounds before exhausting the fuel, crossing the courses of the other ships in convoy. The drawing presents the track of the torpedo that after travelling distance of meters starts to circle with diameter of meters. The blue dashes represents the ships in convoy length of the ship meters, distance between ships in the column meters, distance between columns meters. The initial assessment stated that such modification was feasible, so on 25 November it was decided to start development of such control device for T I wet-heater and T II electric torpedoes. The control escort radar warning receiver was temporarily designated as " K-Einrichtung" Kurvensteuerung-Einrichtung. The theoretical researches proved that only small fragments of the track of the torpedo circling with so large diameter provide the correct impact angle, assuring the proper operation of the impact pistol i. Moreover, the rudder deflection required to make turn of so large diameter above meters was only 0. The torpedo track deviated from the circle because it was impossible to precisely control so small rudder deflection. Drawing 2. Impact angles of the torpedo circling escort radar warning receiver diameter of meters. Drawing 3. Loop Schleifenläufersipral Spiralenläufer and zigzag Sägenläufer torpedo run. Finally, the loop run was selected for further development. The torpedo track had a shape of lengthen loops which moved along the convoy course, so longer fragments of the torpedo tracks provided required impact angle. The spiral run was rejected due to constructional difficulties and small chances for success. The zigzag run was designated for future development later implemented as Lut torpedoes. According to the schedule, 12 G7a wet-heaters torpedoes were to be converted to the experimental pattern-running models in Januarywhile in Escort radar warning receiver and Junehundreds of pattern-running G7a and G7e torpedoes were to be combat ready. The development and testing of the control device was conducted by TVA department in Gotenhafen-Oxhöft Gdynia-Oksywie. The torpedoes fitted with this gear were designated as Fat Federapparattorpedooften mistakenly expanded as Flächen-Absuch-Torpedo and were marked with green strips painted on the torpedo rudder. The development was delayed so refined version of the pattern-running G7a wet-heater torpedo was ready only on the beginning of October. The turn radius was equal to meters. The Fat control gear consisted of type GA VIII gyro built-in straight running wet-heater T I torpedoes and electric T II torpedoes and Fat pattern gear. Drawing 5. Fat control gear type GA VIII gyro to the right, pattern gear to the left [1]. Photo 1. Fat control gear type GA VIII gyro to the right, pattern gear to the left. When the torpedo left the tube, it turned by pre-set angle so called gyro angle, Germ. Both turn and straight run was controlled by type GA VIII gyro. The spinning gyro disc determined the fixed reference plane in space this plane was perpendicular to the longitudinal axis of the torpedo tube. The gyro angle was set relative to this reference plane. The gimbals were coupled with pneumatic steering-engine which actuated the rudder of the torpedo. The gyro angle was set by rotation of the setting spindle Germ. Photo 3.
The production rate of the Fat torpedoes was only per month. Nach Sek. First of them was not launched because of failure of the electrical firing system , the respective control lamp indicating that firing lever was triggered also did not lit up in response to lighting the lamp up, the torpedo tube operator should launch torpedo manually. The component for calculating maximum distance to target at the moment of the torpedo launch: early version before and late version after Firing data : torpedo running depth 6, target speed 8, angle on the bow , bow left. At some point, the calculator operator reports " Deckung!

Manpower.U 's attack, 23 March grid CB The result is irrespective of the own course and speed and target course. Navigation devices with POI function and speed camera apps are permitted. If necessary, confiscation of the vehicle in the case of permanently installed devices. Therefore, the U-Boat that intended to attack with Fat torpedoes was obligated to transmit a special radio message, so called " Fat warning" Germ. Therefore, this article should be treated as a kind of entertainment. Er wartet, bis das neue Ziel einwandert und befiehlt: » Rohr vier … los! Again approached.

The new Navty P1 is both a legal accelerometer and professional radar detector. Gunboat running at high speed, RPM, makes small course changes. The warning was valid for 30 minutes. When the torpedo left the tube, it turned by pre-set angle so called gyro angle, Germ. The wet-heater torpedo launched during the second approach missed the target because of incorrect attack data overestimated target speed. Because the man at the hydrophone could hear the torpedoes of the other misses until the end of their run but in this case heard nothing after 40 seconds, I assumed that the tanker is equipped with nets. The indentation forced the right turn, while the notch the left run. Photo 9. Eine Meldung von der Brücke wird durchgegeben: » Mastspitze backbord voraus!

Scope of delivery and features The Navty P1 is shipped with the current database and the radar function disabled, so it is legally sold and shipped as an accelerometer.

If length was too long or too short, the torpedo started to maneuver behind and in front of the convoy respectively, being completely useless. The torpedo track had a shape of lengthen loops which moved along the convoy course, so longer fragments of the torpedo tracks provided required impact angle. The pattern running type G7a Fat wet-heater torpedo could run only at speed of 30 knots the speed setting WS — Weitschuss.
