Concorde had a maximum cruising altitude of 18,300 metres (60,000 ft) and an average cruise speed of Mach 2.02 (2,150 km/h; 1,330 mph), more than twice the speed of conventional aircraft. [ 130 ]
For example, Concorde had very high drag (a lift to drag ratio of about 4) at slow speed, but it travelled at high speed for most of the flight. Designers of Concorde spent 5000 hours optimizing the vehicle shape in wind tunnel tests to maximize the overall performance over the entire flightplan.
A maximum speed of 2,443 km/h (1,518 mph; 1,319 kn) (Mach 2.35) was reached with afterburning. [10] Afterburners were added to Concorde to meet its take-off thrust requirement [ 16 ] and were not necessary for supersonic cruise; the Tu-144 used maximum afterburner for take-off and minimum for cruise.

The maximum speed without afterburning was Mach 1.05. [6] The P.1 prototype of the English Electric Lightning, powered by non-afterburning Armstrong Siddeley Sapphire engines, exceeded Mach 1 on 11 August 1954. A week previously, on 4 August, the P.1, WG760 flown by Roland Beamont on its maiden flight, had unknowingly exceeded Mach 1 in a climb ...
