The relative tight correlation between maximum thrust force produced and the amplitude of the distance moved by flippers during the downstroke suggest that this is the major mechanism by which thrust force is modulated.
Thrust force can be correlated with feed rate, the most important parameter affecting thrust force.
The maximal velocity of the proposed motor is 735 mm/s and the maximal thrust is 1.1 N.
It is found that the balance system reduces thrust by providing a thrust force which counteracts the total impeller thrust force thus reducing the thrust bearing load.
Critical thrust force has also not been precisely tracked.
Output parameters were the thrust force and cutting torque.
The essential output is the friction force the machine must overcome (the required thrust force), that can be compared with the available thrust force.
Later, the lift-force was horizontally applied as the thrust force in land/water wind-crafts.
The results indicate that: When the mass flow is around 92.8 g/s, the thrust force reaches the designed thrust.
Cutter forces, i.e., thrust force, rolling force and specific energy values are recorded for each cut.
