STINGER BLOCK 1<\/h2>\n\n\n\n

The Akronauts\u2019 most ambitious project yet, a cryogenic regeneratively cooled engine dubbed “Stinger”<\/p>\n\n\n\n

Traditional manufacturing methods. Machined in-house at the University of Akron College of Engineering machine shop.<\/p>\n\n\n\n

Utilized regenerative cooled channels & film cooling despite the manufacturing complexity <\/p>\n\n\n\n

Designed and tested two injector types, an FOF triplet and a LOX-centered pintle <\/p>\n\n\n\n

Hotfired 5 times from April to August of 2024<\/p>\n<\/div>\n\n\n\n
