GEOGRAPHICAL AND GROUND CONDITIONS 4.1 Altitude Definition of altitude Elevation above Mean Sea Level (MSL) Where possible gas turbine engine test facilities should be located close to sea level, this is due to the fact

21、that as altitude increases the properties of air change. This change in air properties has the effect of decreasing the developed thrust of engines due to a decrease in air density and a reduction in oxygen levels. Although Performance Engineers attempt to correct all gas turbine engine testing data

22、 back to International Standards Atmosphere (ISA) day conditions (15 C) at Sea Level Static (SLS 1013mbar) these corrections and extrapolations can cause difficulties in achieving a successful correlation with a master test facility that is closer to sea level. These difficulties would be increased

23、in regions where large temperature or humidity variations from the master test facility location produce additional variables. This inherent level of measurement uncertainty at the time of the correlation could potentially cause errors in the final pass off data for each subsequent engine tested. To

24、 avoid this uncertainty a significant amount of engineering time and effort can be spent by the engine OEM developing analytical engine performance models to recreate and understand the altitude effects, however, these models are expensive to produce and validate and unless created perfectly could h

25、ave levels of uncertainty themselves due to calculation errors. These uncertainties could lead to engines that should have passed test failing or more worryingly engines that should have failed test passing and being released into service. It should be noted that although it is more challenging to c

26、orrelate test facilities at higher altitudes, facilities have been successfully established and validated in high altitude areas such as Johannesburg (1694m) and Addis Ababa (2300m). _ SAE INTERNATIONAL AIR6197 4 of 124.2 Terrain Definition of Terrain A tract of land as considered with reference to

27、its natural features Terrain can have a large influence on a potential site selection from both a construction, acoustic and operational effectiveness perspective. Sites with excessives gradients, slopes or changes in ground levels will require more extensive efforts during the clearing levelling an

28、d foundation digging construction phases and may additionally require banking and shoring up of the uphill sections and diversion of potential water runoff areas. The presence of nearby hills, mountains, cliff faces and rock outcrops should be taken into consideration during site selection as these

29、features can cause acoustic problems to local populations due to reflected noise and acoustic funneling. In areas with a high possibility of the ingress of ground based sand or dust where facilities with horizontal intakes are proposed suitable features such as concrete hardstandings, inlet steps or

30、 inlet dust traps should be considered within the facility design (also see 5.6 - Airborne Dust and Sand). Sites that are in close proximity to the ocean will have to take into account the effects of saline deposits on the engines being tested and the acceleration of corrosion on the facility struct

31、ure and equipment (also see Salt Fog). Sites that are in close proximity to lakes and rivers or in low lying coastal areas should consider the risk of flooding and where the risk is significant design the facility with appropriate features such as plinth foundations and a reduction in the amount of

32、subterranean features such as bulk fuel storage tanks, fuel pipe trenches and effluent sumps etc (also see 4.3 Ground Conditions). 4.3 Ground Conditions Prior to selecting the final site for a new or relocated test facility a thorough geotechnical site survey should be conducted by specialist geotec

33、hnical engineers to gain an appreciation of the above and below ground conditions of each potential site including the water table and properties of the strata. The geotechnical site survey will comprise of a topographical review, existing subterranian services and features review, drilling of bore

34、holes, intrusive survey, trial pits, soakaway pits, standard penetration tests, engineering properties of strata, topsoil investigation, made ground investigation, contamination assessment and CBR tests. Geotechnical site surveys are particularly important for areas such as reclaimed land, marshes,

35、flood plains or areas that may have been subject to mining activity or land that could potentially contain historic remains. The results of the geotechnical review will influence the selection of the site and subsequently the selection of the foundations, floor slab design, load bearing featues, sub

36、terranian features, road and pavement design and describe other risks to operations such as flooding, subsidence or transfer of ground borne vibration. 4.4 Seismic Activity Definition of seismic - subject to or caused by an earthquake or earth vibration Where possible gas turbine engine test facilit

37、ies should not be considered in areas of of seismic activity such as earthquakes or earth tremors. Catastrohic seismic events will render the facility inoperable immediately and will be a significant health risk to personnel. Lower level seismic activity will damage the facility infrastructure over

38、time and will become a significant cost burden to the operators and a potential source of health risks to personnel. If gas turbine engine test facilities have to be constructed in areas of seismic activity then special consideration should be given to the design and selection of materials for const

39、ruction and foundations such as high-seismic lateral steel frame members and vertical steel pipe piles. In addition it is recommended that appropriate methods of equipment and engine retention should be considered that are capable of withstanding lower level seismic events. These additional features

40、 will have addittional costs and maintenance burdens associated with them. _ SAE INTERNATIONAL AIR6197 5 of 125. WEATHER CONDITIONS 5.1 Wind In areas of high or gusting wind it is important that the design and equipping of the test facility allows for the appropriate aerodynamic conditions for the e

41、ngines under test. Consideration should be given to the the introduction of cross wind breakers at the entrance to the air inlet and turbulence control screens within the test cell to reduce the effects of the outside conditions on the internal aerodynamics of the test cell. To reduce the possible e

42、ffects of Hot Gas Ingestion (HGI) between the exhaust and air inlet system it is recommended that gas turbine engine test facilities are orientated Head to Wind i.e the air inlet of the test facility points towards the prevailing wind direction and that appropriate inlet and exhaust stack heights ar

43、e designed in to the facility. Prevailing wind direction and its effects on the pollution signature of the facility should also be considered during site selection as it could cause neighbors in one direction to receive higher pollution levels (Also see 8.4 Emissions). The effects of wind loading on

44、 building design should be considered at the design phase in regions where high or gusting winds can be expected. Suitable features and materials should be considered within the facility to mitigate the effects of wind loading on the facility building structure. These features and materials could af

45、fect the initial cost and subsequent long term maintenance cost of the facility and should therefore be considered prior to site selection. 5.2 High Temperatures High temperatures can affect the design, equipping, construction, validation and supportability of new or re-located gas turbine engine te

46、st facilities. 5.2.1 High Temperatures - General Suitable features and materials should be considered within the facility to mitigate the effects of extreme high temperatures on the operators, facility equipment and building structure. These features and materials could affect the initial cost and s

47、ubsequent maintenance cost of the facility and should therefore be considered prior to site selection. In addition it should be noted that sunlight UV effects on open air test facilities can affect facility equipment such as instrumentation lines and suitable protection should be provided or planned

48、 maintenance undertaken to reduce UV degradation affects. High temperatures can affect construction schedules due to the detrimental effects of hot weather on the workforce and building materials such as concrete or mortar. 5.2.2 High Temperatures - Commissioning & Correlation Engine temperature limitations could prevent engin
