Abstract
Methods and apparatus for reducing transmission of mechanical waves according to various aspects of the present invention comprise a set of isolators and a series of stops configured to isolate a piece of equipment in a projectile. The stops serve to limit the amount of stress loading placed on the isolators during transient events where loads associated with launch of the projectile or deployment of flight control surface might damage the isolators or cause the equipment to fail.

An apparatus for isolating a vibration sensitive device located inside of a projectile from a mechanical wave imparted on the projectile, comprising:
- a base having a lower base member and an upper base member, wherein:
- the lower base member is configured to connect to an inner portion of the projectile;
- and
- the upper base member connects to the lower base member;
- an adapter plate coupled between the lower base member and the upper base member, wherein the adapter plate is configured to attach to the vibration sensitive device;
- an isolator disposed between the lower base member and the adapter plate, wherein the isolator is adapted to inhibit transmission of the mechanical wave from the projectile to the vibration sensitive device;
- an axial stop connected to the lower base member, wherein the axial stop is configured to limit a compressive force applied to the isolator;
- and
- a lateral stop connected to the lower base member, wherein the lateral stop is configured to limit at least one of a lateral force, and a torsional force applied to the isolator in response to the mechanical wave.
A method for isolating a body inside of a projectile from effects a mechanical wave imparted on the projectile, comprising:
- attaching an isolator to a base connected to an inner portion of the projectile, wherein the isolator is configured to substantially inhibit transmission of the mechanical wave to the body;
- attaching a stop to the base, wherein the stop is configured to limit at least one of a compressive force, a tensile force, a lateral force, and a torsional force applied to the isolator in response to the mechanical wave;
- attaching a pin to the base, wherein the pin is configured to limit at least one of a lateral force and a torsional force applied to the isolator in response to the mechanical wave;
- and
- coupling the body to the base such that the isolator is disposed between the body and the base.
