Thanks to progress achieved in the past decade, shell investment casting allows the manufacture of aircraft structural parts of high complexity and enables extremely attractive weight and cost benefits when compared to traditional solutions such as machining as a hogout, sheet metal assembly or sand casting. Specific technological aspects are presented, as well as static and dynamic data obtained on D357 castings obtained through premium quality casting processes. The comprehensive data base generated on premium quality investment castings offers airframe and aeroengine designers a unique chance to achieve substantial gains on major structural parts such as aircraft doors or highly loaded gearbox housings.
