SPF/DB titanium is a proven production technology at BAe. Until recently SPF of aluminium alloys has been confined to secondary and tertiary aircraft structures due to the lack of a suitable structural alloy. Project studies have indicated that useful cost and weight savings can be achieved by the application of SPF aluminium to various military aircraft primary structure components. The development of high strength 7475E and 8090 SPF aluminium alloys offers the potential of manufacturing such structures. The objectives of achieving manufacturing cost savings and weight benefits have been verified through design and manufacture of the L/H module door for Tornado. The subsequent scale-up manufacture of a large complex S shaped SPF 8090 EAP main undercarriage door has also been demonstrated. This paper discusses the manufacture of the Tornado door.
