The block equations refer to these quantities: T is the propeller thrust. Q is the propeller torque. ρ is the fluid density. You can specify the fluid density using the Density parameter or the Rho port. θ is the pitch angle. D is the Propeller diameter parameter. ω is the propeller...
More complex mechanisms with four or more blocks are described by systems with equations of higher degrees which do not have an analytical solution in the form of roots. A semi-analytical solution is also given for locating the point of application of the active thrust....

However, employing a stress-block constitutive law would require deriving separate analytical formulas for each TULs and for both unstrengthened and strengthened cross sections (single or double strengthening). Conversely, the approach proposed here is designed to be general and adaptable to any elasto...
To solve this problem, De Vries [3] and Tschauner [4] proposed the relative motion models for rendezvous in elliptical orbits, which are more accurate than C-W equations when reference orbits are noncircular, but nonlinear terms involved in these models would complicate the control task. The ...

Fig. 1. The transmission structure and the control block diagram of the EMA system in one channel. To simplify the modeling of the TVC-EMA, the mass properties of the gears, screw, nut and drive pole are converted into the properties on the motor rotor, and the engine is regarded as th...
The line of thrust closest to the geometrical axis of a rigid-block arch is researched. • A numerical procedure based on thefinite difference methodis formulated. • A“performance factor”, the Heymanian geometricalfactor of safetyrevisited, is formulated. ...
(9), the circuit 40 selects the equation represented by either block 42 or 43. The circuitry in the selected block provides as an output a signal representing PTNand this is applied to the circuitry represented by block 23 which determines αe. The remaining circuitry in program memory 21 ...
