What is the limiting factor in the maximum speed of the Concorde? In other words why does it cruise at the speed it does and not faster. Lets see how many of you knowitalls can answer this one.

Well, I believe it 's the limit of the material it was built on. The Concorde was built using alumunium alloy, which was the boundary of the technology then. The affect of kinetic energy heating on the fuselage structure restricted the max speed to mach 2.2. (at that speed the air passing thru the fuselage creates friction and thus high temperature of about 250 degrees F !) If it was to go faster, either very heavy stainless steel or extremely expensive titanium alloy would have to be utilized.

Good work VR-HKG..and the actual skin temperature, or that which is exprienced on the nose which limits the Concordes speed is 128c (262f)..

BTW...VR-HKG the classic was the first A/C l flew into Kia Tak on.

All the best ...

The correct answer is indeed the temperature of the nose. Good job.

S what if that wasnt the limiting factor? How fast could it go with the current engines?
