1. An engine, comprising:
an air intake arrangement configured to receive air;
a heat exchanger arrangement arranged downstream of the air intake arrangement, configured to cool the air, and comprising a plurality of heat exchanger modules; and
one or more turbomachinery components configured to receive cooled air from the heat exchanger arrangement;
wherein:
the plurality of heat exchanger modules are each arranged to be generally centred on and to be arranged along a longitudinal axis of the engine; and
at least one of the plurality of heat exchanger modules is arranged to partially overlap with at least one other one of the plurality of heat exchanger modules relative to the longitudinal axis of the engine,
wherein each of the plurality of heat exchanger modules has a respective length, and wherein at least one of the plurality of heat exchanger modules is arranged such that its respective length only partially overlaps with the respective length of at least one other one of the plurality of heat exchanger modules, relative to the longitudinal axis of the engine.
