1. A non-incendiary projectile tracer comprising an energy harvesting assembly, the projectile comprising:
an inlet provided at a tip of a casing of the projectile;
multiple outlets provided circumferentially around an outer surface of the casing proximate the tip;
a turbine having a monolithic structure with a plurality of turbine blades and a conical end portion, the conical end portion mounted to a shaft configured to receive the turbine blades;
an airflow channel structure extending from the inlet in a generally axial direction through the turbine to the multiple outlets such that air passes over the conical end portion of the monolithic structure of the turbine;
a generator coupled to the turbine via the shaft, the generator configured to convert energy from the turbine into electrical energy; and
an electronic component configured to be powered by the electrical energy,
wherein the projectile tracer is non-incendiary.
