When Blackhawks go down Verisurf is used to bring them back into service.
When United States Armed Forces’ Blackhawk helicopters are damaged they are sent to one of several Maintenance Repair and Overhaul (MRO) facilities. They are repaired with a unique system developed by ADC Engineering Technology, Gardena, California. The H-60 Crash Damage Repair System combines a specially designed Laser Tracker Aircraft Alignment Fixture (LTAA), with a laser tracker and Verisurf Metrology Software. This unique MRO solution is located at the U.S. Navy Fleet Readiness Center Southwest (FRCSW), San Diego, CA, U.S. Coast Guard, Aviation Logistics Center, Elizabeth City, NC and U.S. National Guard, Aviation Classification Repair Activity Depot (AVCRAD), Gulfport, MS and other depot repair locations around the world. The facilities are meant to quickly and costs effectively restore damaged helicopters to flight-ready status.
Reset and Recap
There are two initiatives driving the idea of repair vs. replacement when possible. Reset is the term currently used to describe the equipment refurbishment process. Reset refers to a series of actions to restore units to a desired level of combat capability to commensurate with future mission requirements. Recap, or Recapitalizing involves overhauling or restoring equipment to improve performance or make it like new from the factory. In some cases this involves reconfiguring current assets for future use, other than what they were originally designed for. An example of this might be taking a proven platform from one branch of the military, outfitting it with different systems or modifying its configuration and redeploying it to a different branch. The military’s version of reduce, reuse, recycle, which makes a lot of sense. Many of today’s military assets are made to last. With good MRO schedules and the ability to restore even crashed or battle damaged assets to like new condition, the military can realize extended duty from its equipment.
H-60 Crash Damage Repair System
The H-60 Crash Damage Repair System is comprised of a highly accurate LTAA cradling fixture, specialized refurbishment and installation fixtures for different parts of the aircraft, laser tracker, laser sighting tower, mobile computer station and Verisurf Metrology Software. The LTAA supports all versions of the Blackhawk Series Helicopter. Designed specifically for these aircrafts the repair system features extendable deck slides and access for upper aircraft measuring and repair, providing a safe and convenient operational environment. The system can be configured according to Depot hanger requirements. The LTAA configuration relies on a Depot hanger having an overhead crane for loading of the aircraft. The R-LTAA has the independence and convenience of ramp loading the aircraft on existing operational landing gear or cart loaded when landing gear is missing or non operational. With either configuration the damaged helicopter is loaded into the LTAA fixture and aligned using hard point locators. These locators are fixed and associated with the placement of known aircraft components including transmission beams, servo beams, oil cooler, engine mounts, drive shaft brackets, 485 bulkhead, canted bulkhead or drag links. Once the aircraft is aligned with one or more of the hard point critical design coordinates it is securely held in place for repairs and realignment. Three dimensional hard point locating data defining both the helicopter and the LTAA fixture is loaded into the Verisurf software platform. With this data in place, the system can inspect the locations and alignment of installed structure and components on the helicopter. It also allows for “self-verification” of the accuracy and alignment of the fixture itself. The complete aircraft can be refurbished back to its original condition with damaged parts replaced and shifts in alignment corrected.
