Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model is a kind of novel rotary flow type water pressed engine, as depicted in figs. 1 and 2, comprise magnesium powder storage tank 1, stirring rod 2, pump 3, the firing chamber makeup of the imports 4, firing chamber 5 and jet pipe 6, described chamber structure 4 is provided with nozzle 7, fuel inlet 8, central shaft 9 and swirl vane 10.
Overall structure of the present utility model as shown in Figure 1, described magnesium powder storage tank 1, pump 3 and firing chamber 5 are separately fixed on torpedo body, and stirring rod 2 is placed in magnesium powder storage tank 1, and Powdered magnesium powder fuel and liquid kerosene are stored in magnesium powder storage tank 1, and stirred, as fuel; Be connected by pipeline between pump 3 with magnesium powder storage tank 1, the fuel inlet 8 in the firing chamber makeup of the imports 4 on the export pipeline aligning firing chamber 5 of pump 3, the fuel in magnesium powder storage tank 1 enters firing chamber 5 by pump 3, and speed fuel is regulated by pump 3.The described firing chamber makeup of the imports 4 is integrated processing structure with firing chamber 5, comprise fuel inlet 8, nozzle 7, central shaft 9 and swirl vane 10, fuel inlet 8 is round structure, fuel inlet 8 periphery circumference is evenly arranged eight nozzles 7, inside circumference circumference is uniformly distributed eight swirl vanes 10, one end of swirl vane 10 is fixed on central shaft 9, the madial wall of the other end and fuel inlet 8 is connected and fixed, enter the fuel of firing chamber 5 first after swirl vane 10, the water entered with nozzle 7 forms stable recirculating zone, realizes the object of steady combustion.
Described central shaft 9 is positioned at the home position of fuel inlet 8, and is fixed on firing chamber 5.
Working principle and process:
Described rotary flow type water pressed engine operationally, magnesium powder in magnesium powder storage tank 1 and liquid kerosene enter fuel inlet 8 as fuel by pump 3 after stirring rod 2 stirs, swirling two-phase flows is formed after flowing through swirl vane 10, produce the superimposed motion flowing to whirlpool and prospect spape, simultaneously, water enters firing chamber 5 from nozzle 7, fuel and water blending smooth combustion, burning generates magnesium oxide and hydrogen and releases a large amount of heat, and end product sprays with the jet pipe 6 of the form of high velocity air from firing chamber 5 afterbody.
Because rotary flow type water pressed engine of the present utility model stores magnesium powder by the kerosene of liquid state and stirred by magnesium powder by stirring rod 2, the uniform flowing in combustion chamber 5 of magnesium powder fuel therefore can be ensured.The swirl vane 10 added at fuel inlet 8 place is good smooth combustion apparatus, and can realize the smooth combustion of magnesium powder fuel and water, the burnout rate of magnesium powder fuel can reach 98.3%.A large amount of heat is released in this reaction simultaneously, sprays from the jet pipe 6 of firing chamber 5 afterbody, and thermal energy becomes kinetic energy to promote torpedo navigation afterwards.
Firing chamber 5 of the present utility model inner oxidizing agent is all by the water extraction confession of torpedo outside during navigation, and the possessive volume of magnesium powder storage tank 1 and pump 3 is also less, therefore has the advantage of saving space and weight.The magnesium powder storage tank 1 that torpedo water pressed engine adds, pump 3 and swirl vane 10 are all common workpiece, are easy to processing.
Embodiment:
Adopt rotary flow type water pressed engine to carry out experimental research, swirl vane 10 angle is 60 °, and the speed of incoming flow of water gets 20m/s, 40m/s, 80m/s respectively, and the entrance velocity of magnesium powder fuel gets 15m/s, 30m/s, 60m/s respectively.Measure the exit velocity of rotary flow type pressed engine and calculate specific impulse, obtaining experimental result as following table:
Table 1 experimental result
From table 1, rotary flow type water pressed engine of the present invention is at inlet water speed 80m/s, and burnout rate during magnesium powder inflow velocity 60m/s is 98.3%, and gas outlet speed is 697m/s, and specific impulse 5019Ns/kg has strong advantage in Modern Navy operation.
