Pulsed Supersonic Jet with Local High Speed Valve

摘要

A pulsed supersonic jet excavator uses a short duration blast of air to excavate using a minimum amount of air and a minimum reaction force. This device uses a fast acting valve to create a jet of air that lasts about as long as it takes to develop. The result is a device that works much more efficiently than existing air jet excavators. This device can be mounted on a small robot and allow it to dig, whereas a normal backhoe type excavator would just lift the robot when attempting to dig in packed earth.
