Abstract
According to some examples, an energy harvesting assembly for a projectile comprises an inlet provided at the tip of a casing of the projectile, multiple outlets provided circumferentially around an outer surface of the casing proximate the tip, and an airflow channel structure extending from the inlet in a generally axial direction through a turbine to the multiple outlets.
Claims14
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.

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;
- a number m of 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, the turbine including a number n of blades extending from the shaft, the blades having a pitch in the range 15-30 degrees, wherein n and m are both greater than 1, and n≠m;
- an airflow channel structure extending from the inlet 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;
- a rearward-facing aperture;
- and
- an electronic component including an illumination source proximate the rearward-facing aperture and configured to be powered by the electrical energy,
- wherein the projectile tracer is non-incendiary.
