Abstract
According to some examples, a non-incendiary projectile comprises a housing defining an internal cavity, and an energy harvesting structure comprising a first part and a second part, the first part provided on an inner surface of the housing, the second part provided in the internal cavity, the second part further comprising a rotation damping system configured to regulate a rate of rotation of the second part in a rotational direction about a flight axis defined by the housing.

A non-incendiary projectile comprising:
- a housing defining an internal cavity;
- and
- an energy harvesting structure comprising a first part and a second part, the first part provided on an inner surface of the housing, the second part provided in the internal cavity, the second part comprising a rotation damping system configured to regulate a rate of rotation of the second part in a rotational direction about a flight axis defined by the housing.
A non-incendiary projectile comprising:
- a housing defining an internal cavity;
- and
- an energy harvesting structure comprising a first part and a second part, the first part provided on an inner surface of the housing, the second part provided in the internal cavity, the first part including an arrangement of magnetic elements configured to generate a magnetic field within the internal cavity, the second part including an armature and a rotation damping system, the rotation damping system configured to regulate a rate of rotation of the second part in a rotational direction about a flight axis defined by the housing;
- wherein, upon rotation of the non-incendiary projectile, the first part rotates relative to the second part;
- wherein a rate of rotation of the first part is greater than a rate of rotation of the second part.
A method for generating energy for a projectile, the method comprising:
- providing an energy harvesting structure comprising a first part and a second part, the first part provided on an inner surface of the housing, the second part provided in the internal cavity, the second part further comprising a rotation damping system configured to regulate a rate of rotation of the second part in a rotational direction about a flight axis defined by the housing;
- and
- imparting a rotational component of motion to the projectile, whereby to rotate the first part relative to the second part.
