Creep resistance of aluminium alloys for the next generation supersonic civil transport aircrafts
Theoretical and Applied Fracture Mechanics, 1999Characterization of the creep resistance of 30 newly developed aluminium alloys is made for structural applications of the next generation Supersonic Civil Transport Aircafts (SCT). These materials refer to the 2xxx, 6xxx and 8xxx aluminium alloy series. Creep behaviour is ranked to the usability and applicability of the alloys according to performance.

The technical aspects of supersonic civil transport aircraft
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1974The paper discusses those technical aspects of a supersonic civil transport aircraft which peculiarly distinguish it from conventional subsonic civil aircraft. The physical, economic and ecological environments in which the supersonic transport must operate are considered and the main stepping stones to the development of the supersonic transport are ...

For supersonic civil transport aircraft, the low-speed aerodynamic characteristics form an important factor in its operational capabilities and in its economic viability. Low drag is a prerequisite to meet the present and future noise and emissions requirements. The application of concepts for leading-edge devices aiming at an improvement of low-speed

Analysis of Flight Mechanics of a new Civil Supersonic Aircraft Conceptual Design
The DLR-project STORMIE investigates novel concepts for supersonic passenger transport, with a particular focus on low boom characteristics. Three aircraft designs are being developed and analyzed for this purpose. This paper presents a flight mechanics analysis of one of these aircraft designs - a supersonic business jet - conducted during the early ...Christmann, C., Sachs, F., Kirz, J.
