Compact Powerfeed Drill
Under a Phase I SBIR contract with the Navy, we designed, built, and demonstrated critical components (the drill heads) of two types of compact powerfeed drill: (1) Nose-Lock Drill; and (2) Tool-Less Drill. The two types of drill each have shafts that are driven by fluid turbines and supported by hydrostatic (water) bearings. Our two drill types are suitable for two different types of applications for limited-access drilling of aircraft structures. Figures 1 and 2 show the head of the Nose-Lock Compact Powerfeed Drill, which we tested in Phase I by drilling smooth burr-free holes through: titanium 6Al-4V, graphite composite, and aluminum plate. Figure 3 shows the holes we drilled through titanium 6Al-4V.
