Abstract:
This report presents details of the process taken to reach the final conceptual design of a hydraulic loading room to be implemented at the MDS AeroTest GLACIER facility. This room is used to house equipment that provides the hydraulic flow necessary to simulate hydraulic loads on partner OEM gas turbine engines. As per consultation with the client, the current configuration of the hydraulic loading room required implementation of HVAC and spill containment measures in conjunction with an enhanced layout plan to create a safe and efficient work environment for MDS AeroTest personnel. The deliverables presented in this report include conceptual engineering drawings, HVAC calculations and analysis(Appendix A), a trade-of study comparing the generated concepts (Appendix B), and relevant research/literature. To address this problem, the design team first analyzed the needs, target specifications, and constraints of the project. The problem was then broken down into the following sub-systems: layout, heating, ventilation, spill prevention, and spill containment. Concepts for each sub-system were generated using concept screening matrices, concept scoring matrices, and individual weighted criterion used to rank each concept. Concepts that ranked highest were developed further in the final design. The layout of the hydraulic loading room positions equipment in such a manner that frees up nearby floor space to allow more room for MDS AeroTest personnel to complete maintenance and HLU installation as required. The HVAC system has been designed to incorporate an insert duct heater into the ventilation ducts which emits heat into the workspace via three high-sidewall diffusers. Air pollutants are captured by three local exhaust hoods placed in front of the spill containment basin. The heating and ventilation systems combined, provide 12 air changes per hour (as per the Skydrol LD-4 MSDS) and 88,250Btu/hr to maintain room comfort in the Northern Canadian climate. The spill containment systems control hydraulic fluid spills through a perforated floor into a custom-gradient basin and is pumped out into an oil drum for recycling. The spill prevention system uses an auxiliary bleed-line to drain the pressure, suction, and case drain steel lines leading to the engine test stand. Hydraulic fluid can be drained...
