ATK Supports the Launch of United Launch Alliance’s Delta IV Heavy
ATK designed and produced the nozzle for the Pratt & Whitney Rocketdyne-built RS-68 engine as well as the nozzle’s thermal protection material, which is capable of shielding it from the extreme heat of launch when external temperatures can exceed 4,000 degrees F. The Delta IV’s RS-68 is the largest hydrogen-fueled engine in the world, utilizing an ATK nozzle that is the first of its kind in a liquid booster engine. The nozzle is manufactured at ATK’s
ATK also supplied 12 key composite structures for the Delta IV Heavy launch vehicle: the interstage that provides the interface between the Common Booster Core (CBC) and the cryogenic second stage, two nose cones for the port and starboard strap-on CBC’s, three centerbodies that integrate the liquid oxygen (LO2) and liquid hydrogen (LH2) tanks, three thermal shields that protect the RS-68 engines during ignition and flight, and three LO2 skirts.
The composite structures are five meters in diameter and range from one to eight meters in length. They are produced using advanced hand layup manufacturing techniques at the company’s manufacturing facility in
