Imitation models of aircraft hydraulic units with account for typical faults
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019 А method based on comparing oscilloscope patterns of operational parameters with reference curves is one of the most promising methods of diagnosing hydraulic systems among the existing ones. Its implementation does not allow accurate localization of the

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage
Advanced Functional Materials, EarlyView.This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

Ground vehicles hydraulic system pneumatic hydraulic valve
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Hydraulic systems equipped with working bodies hydraulic drives are widely used in ground vehicles. The researches show that one of the modern hydraulic drives problems is the destruction of flexible high-pressure hoses and the unauthorized pressure fluid discharge into the atmosphere.
