Product Code:SAE AIR34 Title:Penalties in Performance of Three-Phase, Four-Wire, 400-Cycle Motors Causes By the Opening of One Phase Issuing Committee:Ae-7a Generators And Controls Motors And Magnetic Devices Scope:The scope of this SAE Aerospace Information Report (AIR) is to present a guide for the determination of probable power output and the effect on the aircraft system that will be experienced when operating three-phase motors with one phase open. Unfortunately, the above subject cannot be resolved by specific rules. Modern aircraft or missile electrical systems are composed of a wide variety of electrical and electronic components. These components react differently under identical impetus due to the latitude of their design. This latidue of design must be allowed wherever possible to the accessory designer due to the various specification requirements. Therefore, it cannot be over-emphasized that the effect on the airplane or missile system, as well as motor operation, of three-phase motors on two-phase power must be thoroughly investigated.【英文标准名称】:Methodsoftestingplastics.Mechanicalproperties.Determinationoffallingweightimpactresistanceofthinflexiblesheet(film) 【原文标准名称】:塑料的试验方法.第3部分:机械性能.试验方法352D:挠性片材薄膜抗落体冲击性的测定 【标准号】:BS2782Pt.3Method352D-1979 【标准状态】:作废 【国别】:英国 【发布日期】:1979-09-28 【实施或试行日期】: 【发布单位】:英国标准学会(BSI) 【起草单位】: 【标准类型】:() 【标准水平】:() 【中文主题词】:柔性材料;薄板材;试验设备;试样;设计;塑料;高聚物;冲击断裂试验;尺寸;膜(物态);冲击试验 【英文主题词】:polymers;plastics;films(statesofmatter);design;sheetmaterials;dimensions;testspecimens;shockrupturetests;testequipment;impacttesting;flexiblematerials 【摘要】: 【中国标准分类号】:G31 【国际标准分类号】: 【页数】:8P;A4 【正文语种】:英语
