    This study presents the design and validation of a Sidestick Captain/First Officer (CPT/FO) prototype with an oleo-pneumatic centering system as an enhancement for the FSTD A320 flight simulator, originally equipped with a conventional mechanical spring system. The objective was to improve the fidelity and response precision of the control system to provide a more realistic and efficient flight simulation experience. The methodology involved mechanical and structural design using SolidWorks, material selection (A36 Steel for the structure and 304 Stainless Steel for the control lever), and validation through static and numerical analyses to ensure structural integrity and system performance. The static analysis confirmed that the components operate within safe limits, and the integration of the oleo-pneumatic system provided a more stable and controlled damping response, closely replicating the behavior of the Airbus A320 Sidestick. Compared to traditional mechanical spring, electromechanical shock absorbers and hydraulic damper systems, the proposed design offers a smoother and more precise response while maintaining simplicity, low maintenance, and costefficiency. This innovation not only enhances the performance of the FSTD A320 simulator but also represents a scalable solution for other flight simulation models, contributing to more effective pilot training and opening opportunities for future improvements through advanced dynamic analysis.

    The study focuses on the automation of the drive system of a filter press in palm oil extraction plants, with the aim of optimizing operational efficiency, reducing manual intervention and improving process accuracy. The proposal replaces the manual drive with a motorized system controlled by a Programmable Logic Controller (PLC). A Siemens motor-reducer, model Z79-LE112MC4P-G040M-PN, was used, which guarantees a torque of 777.75 Nm and an output speed of 40 rpm, sufficient to efficiently tighten and release the filter press. The system control was implemented by a Siemens LOGO 230RC PLC, complemented by an AM2 analog expansion module to interpret strain gauge signals. These signals determine the exact moment to stop the motor-reducer once the programmed tightening force is reached. Programming was done in Ladder language using LOGOCONFORT software. The integration of these components improves system consistency and reliability, standardising processing times and reducing physical effort. The results highlight an increase in productivity and operational safety, aligning with modernisation trends in the palm oil industry. This advance represents a significant step towards greater sustainability and competitiveness of the sector.

    <jats:p>The goal of this paper is to obtain an automated system for the control of the quality of the combustion gases of a boiler. The concentration of oxygen present in the combustion gases is detected by means of a lambda sensor, and a proportional PID controller automatically regulates, through an actuator, the air inlet to the boiler, thus ensuring the emission of CO2 and other polluting gases into the atmosphere within the parameters established by the current environmental regulations. The control system has an HMI display and a modular PLC. The results achieved also ensure the reduction of fuel consumption of the boiler.</jats:p>

    The aim of this research is to determine the average fluid velocity values and the average total pressure at the outlet of the ventilation system conduit for the drying, by air impulsion, of pineapples in packing plants, in order to ensure the required humidity level of the crown for its proper packaging. The CAD model of the air conduction was obtained in Solidworks and Computational Fluid Dynamics (CFD) techniques were applied to simulate the performance of the ventilation system. Air was indicated as the type of fluid, and an internal analysis of the pipe with roughness Rz = 3.2 μm. As a computational domain, the pipeline was established, from the connection to the fan to the outlet diffuser. As boundary conditions were established; a W and Z Manufacturing regenerative fan at the inlet of the flow pipe 618,439 m3/h, and at the outlet of the pipe the value of atmospheric pressure. As a result of the simulation, an average velocity value at the diffuser outlet of 127.294 m/s was obtained, higher than the required 96.06 m/s. An average total pressure value of 111718.73 Pa was obtained in the conduit suitable for the proposed purposes. For the conveyor belt, it is recommended to use, in each row of pineapples, the simulated fan with a simple diffuser with a rectangular section of 1 x 20 cm, or a regenerative fan with a flow of 1248.77 m3/h and a diffuser with two-outlet bifurcation.</jats:p>
