Ram accelerator system
One or more ram accelerator devices may be used to form one or more holes in geologic or other material. These holes may be used for drilling, tunnel boring, excavation, and so forth. The ram accelerator devices propel projectiles which are accelerated by combustion of one or more combustible gasses in a ram effect to reach velocities exceeding 500 meters per second.
1. A system comprising:
a control system comprising:
a memory storing computer-executable instructions to determine one or more firing parameters;
a processor to execute the computer-executable instructions;
a ram accelerator configured based at least in part on the one or more firing parameters, the ram accelerator comprising:
a plurality of sensors configured to communicate with the control system;
a plurality of ventless sections connected to one another by section separation mechanisms, wherein one or more of the sections are configured to contain one or more combustible gasses; and
a ventless detonation gun connected by a section separation mechanism to the plurality of ventless sections.
2. The system of claim 1 , the ram accelerator having a first end proximate to the ventless detonation gun and a second end distal to the ventless detonation gun, and wherein the second end is at least partially in contact with one or more of a geologic material or a fluid.
3. The system of claim 1 , wherein section separation mechanism comprises a ball valve configured to, when open, pass a projectile.
4. The system of claim 1 , the section separation mechanism comprising:
a supply spool to store diaphragm material;
a takeup spool to retain used diaphragm material; and
one or more sealing assemblies to maintain a seal between a portion of the diaphragm material and at least one of the plurality of sections during operation.
