1. A perforating apparatus comprising:

  • a body configured to contain;

    at least one non-explosive fuel source disposed in the body comprising a first fuel type configured to produce a first mass flow rate and a first burn rate, and a second fuel type configured to produce a second mass flow rate and a second burn rate, wherein at least one of the first flow rate and the first burn rate is different from the second mass flow rate and the second burn rate;

    an initiator configured to initiate a burn of said at least one non-explosive fuel source, causing said at least one non-explosive fuel source to produce a force comprising a selected mass flow rate, a selected burn rate, or combinations thereof, that selectively changes from the first mass flow and the first burn rate to the second mass flow and the second burn rate while the non-explosive fuel source is burning; and

    a port configured to project the force to form an opening in a first downhole object while minimizing collateral damage to at least one second downhole object, wherein the at least one port is configured to direct the force as change occurs in the selected mass flowrate, the selected burn rate, or combinations thereof.
