Various studies have been done to find out the parameters affecting the performance, and it was found that the rate of flow, orifice discharge coefficient, pressure drop across orifice, orifice dimensions, polytropic index, geometric parameters of chambers (length and diameter), internal gas pressure, hydraulic fluid properties, strut stroke length, unsprung mass, vertical forces acting on the shock strut, sliding friction, static seal friction, etc., play an important role in determining the shock strut performance [3, 4, 5, 6].
The sum of all polytropic enthalpy differences in the whole charging system consists of the necessary work for the isentropic pressure rise, the irreversible entropy generation due to the fluid movements and the lost heat over the wall.
There are four causal genes identified so far, including solute carrier family 20 member 2 ( SLC20A2 ), platelet-derived growth factor receptor beta ( PDGFRB ), platelet-derived growth factor subunit B ( PDGFB ), xenotropic and polytropic retrovirus receptor 1 ( XPR1 ).[2] In this study, we reported a familial IBGC pedigree caused by a novel SLC20A2 mutation.
