Abstract
This report outlines the preliminary design and characteristics of a
hypersonic aircraft for a flight at Mach 10 using only scramjets for two
nvnutes at 100,000 feet. There are many design problems that have to be
addressed for such a highspeed flight. These include aerodynamic,
ther~a1,logist~caanl d structural problems.
Th~sre wrt contains ideas to deal with these problems that have been
exarrilned by our research team, the gold team. Aerodynamic calculat Ions,
