Control of Helicopter Using Virtual Swashplate
DronesThis article presents a virtual swashplate mechanism for a mini helicopter in classic configuration. The propeller bases are part of a passive mechanism driven by main rotor torque modulaton, this mechanism generates a synchronous and opposite change in ...

Transient start-up of an electric swashplate refrigeration compressor
Applied Thermal Engineering, 2021 Abstract The design of compact, high performance electric swashplate refrigeration compressors demands a clear understanding of different physical phenomena and their interactions taking place inside the compressor. The dynamic characteristics of the compressor are associated with the start-up transients of the swash-plate mechanism and the time ...

Real gas model for an electric swashplate refrigeration compressor
International Journal of Refrigeration, 2020 Abstract A real-gas, restricted-flow valve model is compared with an ideal-gas, ideal-valve model for a 10-cylinder swashplate refrigeration compressor. Real gas properties of R134a are evaluated using the NIST standard reference database. A minor-loss discharge-coefficient approach is used to model the refrigerant flow rate through reed valves while

Effects of Material Selection on the Remanufacturability of a Swashplate in an Axial Piston Pump
Journal of Advanced Manufacturing and ProcessingABSTRACT A swashplate is a critical component in an axial piston pump for motion transformation that undergoes cyclic loading. Traditionally, swashplates are not designed to have multiple lives of operation. According to industry experts, a remanufacturability analysis of swashplates suggests that the scrap rate is high.

Multi-mode fault dataset for aviation piston pump based on standard test procedureMendeley Data [PDF]
Data in BriefThe constant-pressure variable-displacement piston pumps on aircraft are typically driven by the engine, providing energy and power for the aircraft's hydraulic systems and fuel servo systems. Due to the varying engine speeds and fluctuating loads in the

Modeling and Performance Improvement of the Constant Power Regulator Systems in Variable Displacement Axial Piston Pump [PDF]
The Scientific World Journal, 2013 An irregular performance of a mechanical-type constant power regulator is considered. In order to find the cause of an irregular discharge flow at the cut-off pressure area, modeling and numerical simulations are performed to observe dynamic behavior of ...
