The wedges are fitted together to form a detonation wave through the high-speed outer explosive . ( It is semi-spherical because the exploding-bridgewire acts as a point-detonator . ) As the wave is transferred to the precisely shaped inner explosive, a new spherical wave centered on the object is formed.

This causes an expanding shock wave which absorbs laser energy at the shock front ( a laser sustained detonation wave or LSD wave ); expansion of the hot plasma behind the shock front during and after the pulse transmits momentum to the craft . Pulsed plasma propulsion using air as the working fluid is the simplest form of air-breathing laser propulsion.

Key difficulties in pulse detonation engines are achieving DDT without requiring a tube long enough to make it impractical and drag-imposing on the aircraft ( adding a U-bend into the tube extinguishes the detonation wave ); reducing the noise ( often described as sounding like a jackhammer ); and damping the severe vibration caused by the operation of the engine.

The detonation wave in the explosive liner hits the metal cavity, reflects, and implodes on the preheated burnt gases, focuses at the center of the hemisphere ( 50 microseconds after the initiation of the exploding wire ) and reflects, leaving behind a very small pocket ( 1 mm ) of extremely high-temperature, high-pressure and high-density plasma.

This warhead type uses the interaction of the detonation wave ( s ), and to a lesser extent the propulsive effect of the detonation products, to deform a dish or plate of metal ( iron, tantalum, etc . ) into a slug-shaped projectile of low length-to-diameter ratio and project this towards the target at around two kilometres per second.

When the 2013 meteor entered into the Earth s atmosphere with an energy release equivalent to 100 or more kilotons of TNT, dozens of times more powerful than the supersonic jet's flyby ( directly underneath the meteor's path ) and as a detonation wave, with the circular shock wave centred at the meteor explosion, causing multiple instances of broken glass in the city of Chelyabinsk and neighbouring areas ( pictured ).
