TITLE : OIL MOVEMENT OF A MECHANICAL VALVE DURING OPERATION
BY : CHAM Consultancy Team - N Proumen
FOR : Dowty Aerospace Ltd
DATE : 1992
PHOENICS Version : 1.6.6
DETAILS :
- Two-Dimensional, Transient flow
- Polar Cylindrical computational grid
NOTES :
- PHOENICS predicts the oil movement and pressure distribution in the
bistable valve design for the A340 European Airbus main landing gear
- Valve is designed for high level damping for normal landings and softer
damping for heavier landings
- PHOENICS was used to determine the forces acting on all internal surfaces
of the valve during flow
- This enabled the Dowty engineers create an optimum valve design option
Pictures are as follows :
