Ohio Helicopter Icing Spray System (OHISS)

Location of Work:

Columbus, Ohio


HHI acted as a subcontractor to Battelle in building a test stand that will be used for in-flight artificial icing and rain testing of the CH-47F Chinook Helicopter in a low-speed low-altitude environment to ensure that these weapon systems are capable of operating within worldwide environmental conditions. HHI self –performed the steel fabrication and installation, we also provided data, power, air and water to the helicopter through an umbilical system. The OHISS was built as an outside testing fixture which required it to be able to hold up against the elements. Essentially the OHISS is a steel tower capable of lifting the 50,000 pound Chinook and all its testing equipment into the air for testing.
