Jet from 2mm drilled fuel feed hole

Each burner cup of the V2 rocket engine injector system has forty-four brass inserts, but each cup also has twenty-four 2mm diameter plain holes, 30 deg apart, drilled into the cup's central wall. To mimic this for testing purposes, we created a brass insert that has a base with just a 2mm central hole. The base is sized to be consistent with the 4 to 5mm cup wall. V2RH image

About Robert J Dalby 9 Articles
Born Ilford, London, the last V2 missile attack on England missing him by 25 miles and 14 years. Read philosophy for nearly a decade - and so naturally pursued a career in astronomy optics and engineering design. Career highpoints: co-inventor of the LRGB imaging method now in use by serious amateur and professional astronomers worldwide. Responsible for the design of a host of devices used in the field of telescopic astronomy. And once ate nine pancakes without passing out. Spends too much time in shadowy corners fiddling with old missile parts to be socially acceptable, but was once described as a geek's idea of a geek. [email protected]
