MULTIMODE GAS-STEAM TORPEDO Russian patent published in 2002 - IPC

FIELD: torpedo weapon. SUBSTANCE: in the known multimode gas-steam torpedo including reservoirs for fuel, oxidant and water, control system and engine connected to the output of the reservoir for oxidant via a steam-gas generator additionally used are a stream-lined extendable air intake with mechanisms for its extension and return, blower, the first and second threshold devices, fuel and water feed restrictors, drive of the air intake and blower mechanisms, torpedo travel depth changing unit, six AND gate units, two OR gate units and two NOT gate units. The second input of the steam-gas generator is connected to the output of the reservoir for fuel via the first AND gate unit, and the fuel feed restrictor and the first OR gate unit, whose second input is connected to the output of the reservoir for fuel via the second AND gate unit. The third input of the steam-gas generator is connected to the output of the reservoir for water via the third AND gate unit, water feed restrictor and the second OR gate unit, whose second input is connected to the output of the reservoir for water via the fourth AND gate unit. The input of the reservoir for oxidant is connected to the output of the torpedo travel depth changing unit via the fifth AND gate unit, air intake, sixth AND gate unit and the blower. The input of the torpedo travel depth changing unit is connected to the output of the reservoir for oxidant via the first threshold device and the first NOT gate unit. The engine output is connected to the second inputs of the fifth and sixth AND gate units via the drive of the air intake and blower mechanisms. The second inputs of the first and third AND gate units are connected to the blower output via the second threshold device, the second inputs of the second and fourth AND gate units are connected to the output of the second threshold device via the second NOT unit, the threshold of connection of the first threshold device is set higher than the threshold of its disconnection, and the second threshold of its disconnection, and the second threshold device is made with an interlocking of disconnection of the device after its connection. EFFECT: enhanced distance of torpedo travel without any increase of the shipborne stores of fuel, oxidant and water. 1 dwg
