Figure 2From: Thrust measurement and thrust balance development at DLR’s electric propulsion test facilitySome common design options for a thrust balance: (a) vertical weigh cell, (b) normal pendulum, (c) torsional pendulum, (d) inverted pendulum, (e) inverted double pendulum, (f) counterbalanced inverted double pendulum. Remark for (b) and (d): the thruster will be tilted too, but for simplification this is neglected in the picture, modified from [7]Back to article page
