Methods and devices for enabling safe/arm functionality within gravity dropped small weapons resulting from a relative movement between the weapon and a rack mount

A method for enabling safe/arm functionality in a gravity dropped weapon, the method comprising:

• attaching the weapon to a releasable rack attached to an airframe;
• providing a generator, having an elastic element, in the weapon such that a first portion of the generator is attached to the weapon and a second portion of the generator is attached to the releasable rack;
• preloading the elastic element to store potential energy therein;
• releasing the weapon from the rack to separate the first and second portions and to thereby release the stored energy in the elastic element such that the elastic element vibrates;
• converting the vibration of the elastic element to an electrical energy;
• and
• providing the electrical energy to one or more components in the weapon.
