        作為英國Bloodhound火箭車項目的產品支持方,米銥英國分公司總共為該項目提供了15支激光位移傳感器。勞斯萊斯公司位于英國德比的測試機構負責進行該項目的檢測工作。9支量程10mmoptoNCDT1700點激光傳感器被用于測量宇航級別金屬鋁(AL7037)質車輪軸向和徑向尺寸,車輪轉速高達驚人的1700km/h。兩支量程2mmoptoNCDT1700點激光傳感器被用于測量測試臺橫梁的熱膨脹。除此以外,測試臺還配備了4optoNCDT 1402點激光傳感器。這些傳感器可以測量測試臺移動,偏差的程度。測試過程中,轉輪轉速成功到達10,429rpm,測試印證了 BLOODHOUND工程師們之前作出的直徑達902.6mm的轉輪在如此高轉速下的膨脹不超過1.6mm的預測。

         

        As product sponsor for the Bloodhound Project, Micro-Epsilon UK supplied a total of 15 laserdisplacement sensors for the wheel spin test carried out at the Rolls-Roycetest bench in Derby (Great Britain). Nine optoNCDT 1700 sensors witha measuring range of 10mm were set up on the test rig to measure theradial and axial run out of the aerospace-grade aluminum (Al 7037) wheel as itrotated at speeds of more than 1700km/h (1,100mph). Two optoNCDT 1700 laserdisplacement sensors with a measuring range of 2mm were set up to measurethe thermal expansion of the frame that runs across the top of the test rig(i.e. for test rig calibration purposes). In addition to the optoNCDT 1700sensors, the test rig was also equipped with four optoNCDT 1402 laser sensors(with a measuring range of 5mm), which were mounted underneath the testrig in a confined space. These sensors measured the run out, alignment andany other movements of the test rig, including the steel hub that the wheel ismounted to. During the test, the wheel was successfully spun to 10,429 rpm. Testresults were similar to the predictions that the BLOODHOUND engineers hadcalculated - the expansion of the wheel’s 902.6mm diameter by 1.6mm was asexpected.
