Case for Small Supersonic Civil Aircraft

Journal of Aircraft, 2005
Civil aviation progress in the last 40 years has included a significant expansion of the small civil aircraft market involving regional jets, business jets, and the emerging personal jets. A significant factor in the growth of the small civil aircraft market is the value of time.

Preliminary Optimization of the Sonic Boom Properties for Civil Supersonic Aircraft

Journal of Aircraft, 2013
In this work a simple model has been used that relates sonic boom effects to the main geometric and operative parameters of the civil supersonic aircraft. In particular, a relation between the maximum overpressure and the aircraft shape factor is employed to define an optimal preliminary design point for the supersonic civil aircraft.

The technical aspects of supersonic civil transport aircraft

Philosophical Transactions of the Royal Society A, 1974
Abstract The 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

Developing noise standards for future supersonic civil aircraft

Proceedings of Meetings on Acoustics, 2013
With renewed interest in civil supersonics, NASA and industry researchers continue to make progress toward enabling quiet civil supersonic aircraft. Gulfstream Aerospace has long been interested in the development of an economically viable supersonic business jet; however, many regulatory challenges still remain for routine supersonic operation ...

Engines for Supersonic Civil Transport Aircraft

Aircraft Engineering and Aerospace Technology, 1961
Because of its high overall pressure ratio and good propulsive efficiency, the jet engine is very efficient for supersonic propulsion. A high thrust per unit power plant frontal area and per unit weight are primary requirements and these imply high combustion temperatures. For a Mach 2.0 aircraft, engine design problems other than this are not outside

Sonic Boom Minimization Through a Simplified Approach for the Preliminary Design of Civil Supersonic Aircraft

16th AIAA/CEAS Aeroacoustics Conference, 2010
In this paper a simple approach aimed to the definition of a supersonic configuration optimized in terms of sonic boom signature will be presented. This approach is based on the application of Carlson’s method that is a simplified method for the calculation of sonic -boom characteristics for a wide variety of supersonic airplane configurations and ...

Creep resistance of aluminium alloys for the next generation supersonic civil transport aircrafts

Theoretical and Applied Fracture Mechanics, 1999
Characterization 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.
