outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

Aircraft braking maneuvers are safety-critical on-ground motions that exhibit complex dynamics and significant dependence on system operating conditions. The fundamental interface between the aircraft ground is landing gear. Among gear components, shock absorbers may be subject to gas leakage during their lifetime, which an anomaly could compromise lateral stability properties of regimes found ...

Abstract The article presents the results of research on relationship between technical condition motorcycle shock absorbers determined diagnostic line and their damping characteristics. basic division absorber tests was characterized, which includes installed in disassembled, carried out a test stand made MTS components. two sets tested using EUSAMA THETA methods, as well for testing removed f...
