4 engines, two next to each other on the under side of each wing. see the following page for more info: http://en.wikipedia.org/wiki/Concorde#Engines
The Concorde had 4 Rolls-Royce engines, each capable of 38,000lbs of thrust For converting lbs->hp, see link below.
4x Rolls-Royce Olympus 593 engines with afterburner
Very few, if any will. They body styles and engines are different.
Rolls Royce Olympus
The Concorde plane used a type of fuel called aviation kerosene, which is also known as Jet-A fuel. This fuel is a type of refined petroleum that is designed for use in jet turbine engines, like the ones that powered the Concorde.
The Concorde is equipped with four Rolls-Royce/Snecma Olympus 593 engines. These afterburning turbojet engines were specifically designed for supersonic flight, allowing the aircraft to reach speeds over Mach 2. The engines feature a unique combination of turbojet and turbofan technology, providing both high thrust and efficiency at supersonic speeds.
mainly b/c it was built to be fast. HUGE Engines, sleek, needle-like fuselage.
A 1994 Concorde uses ATF +4.
Concorde was able to break the sound barrier by using powerful engines and a sleek design that minimized aerodynamic drag. By generating sufficient thrust and overcoming drag, Concorde was able to reach speeds beyond the speed of sound, allowing it to break the sound barrier.
I could while landing, but the higher the aircraft the thinner the aircraft could travel faster. Also, the engines on a Concorde were extremely loud, so it flew higher so it wasn't a nuisance.
