Mitsubishi QJ71BR11

風(fēng)洞螺旋槳實(shí)驗(yàn)?zāi)Ｐ筒捎肗ACA5946三葉槳，葉型為CLARKY系列。漿葉角可調(diào)（15～40°），槳盤直徑為0.894m

，在0.75r處漿葉玄長(zhǎng)為0.055m。漿葉為鋁型材加工而成。標(biāo)準(zhǔn)槳和無螺旋槳實(shí)驗(yàn)是在定轉(zhuǎn)速n和改變風(fēng)速以達(dá)到改

變前進(jìn)比K=VDnS進(jìn)行的，風(fēng)速V為0～60ms。
　　測(cè)控系統(tǒng)在一定的風(fēng)速或動(dòng)壓下，計(jì)算機(jī)實(shí)時(shí)采集系統(tǒng)同步采集9個(gè)點(diǎn)；實(shí)際轉(zhuǎn)速nm，電機(jī)的電流，電壓（Im，

Um）瞬時(shí)值。六分量天平瞬時(shí)值不但可以提高其精度，同時(shí)通過屏幕顯示出測(cè)試參數(shù)在實(shí)驗(yàn)過程中的大值和小值，

觀察數(shù)據(jù)的穩(wěn)定性。
　　計(jì)算機(jī)采用工控機(jī)IPC-810機(jī)箱，IPC-68Ⅱ主板，可提高抗干擾能力及可靠性，另外在IPC-68Ⅱ主板上還帶有

10M100M自適應(yīng)式網(wǎng)卡，連網(wǎng)方便。計(jì)算機(jī)實(shí)時(shí)采集系統(tǒng)采用Windows9598NT作為操作平臺(tái)，可支持WindowsCVI軟件

，提供友好的交互式編輯和計(jì)算機(jī)屏幕圖形顯示。SPORLAN 400 PSIG 1/2" ODF SOLDER SUCTION FILTER, SF-114 *NEW*
