Err, the air is considerably slowed-down in the compressor i.e. it's a convergent duct. The air is then accellerated in the diffuser (a divergent duct) and directed into the combustion chamber.
TCF:
if the aircraft/engine is
static, the outside air must be accelerated as it is being sucked into the intake by the fan and the compressor, after which the convergent duct does its thing to slow it down.
