Destroy Vibrations
Vibrations Destroy Performance. It's Time to Destroy Vibrations

Our Impact

Over an 18-month USAF Air Combat Command Study “07-196R (7-04), HH-60 Track-and-Balance Vibration Information Solution Refinement Software Operational Utility Evaluation,”  the IVT VIBS platform was selected as the top track-and-balancing methodology and immediately added to the USAF Technical Order as an approved balancing methodology (T.O. 1H-60(H)G-2-15, page 1-5, paragraph 1.2.8 “Alternate Adjustment Solution”).

 

The U.S. Air Force study included 24 HH-60s across four different bases.  The results below are the average of the entire fleet over the length of the study using all flight profiles.  Consequently, we believe this data reinforces why VIBS is the world’s best track and balancing solution:

·        Main Rotor (avg. ips):  0.094

·        Tail Rotor (avg. ips): 0.047

·        Independent Drive Shaft (avg ips): 0.157

 

 

Furthermore, the Air Force reported the following savings in man-hours used and maintenances adjustments over the course of the study for VIBS:

·        Main Rotor System:   75% reduction in number of adjustments; 95% reduction in man-hours

·        Tail Rotor System:     65% reduction in number of adjustments; 88% reduction in man-hours

·        Engine Driveshafts:   55% reduction in number of adjustments; 78% reduction in man-hours

 

The final AATC evaluation of VIBS was:

-        “It significantly reduces the number of maintenance touches, runs, and number of hours required to balance the main rotor, drive shaft, and tail rotor on the HH-60 aircraft.

 

Procurement and fielding of the software, or similar software using the same balancing algorithms, is recommended.”

OUR IMPACT

 

It's easy for a company to tell you how great they are...However, we prefer to let our customers tell you about the difference we are making in their business and operations:

“During multiple demonstrations, a formal test, and operational use on H-60s routinely flown at the heaviest gross weights of any Blackhawk derivative fleet, the [VIBS] technology has proven to be revolutionary.”

THE DETAILS

Through an 18-month US Air Force (Air Combat Command) study at four military bases using 24 HH-60s, the IVT VIBS platform was selected as the top track-and-balancing methodology and immediately added as an approved balancing methodology (see T.O. 1H-60(H)G-2-15, page 1-5, paragraph 1.2.8 “Alternate Adjustment Solution”).

 

Here are the fleet-wide results of the VIBS implementation:

  •     Main Rotor (avg. ips):  0.094

  •     Tail Rotor (avg. ips): 0.047

  •     Independent Drive Shaft (avg ips): 0.157

 

More importantly, here are the operational results VIBS provided to the US Air Force's HH-60 fleet: 

Main Rotor System:    

  • 75% reduction in number of adjustments

  • 95% reduction in man-hours

 

Tail Rotor System:    

  • 65% reduction in number of adjustments

  • 88% reduction in man-hours

 

Engine Driveshaft:   

  • 55% reduction in number of adjustments

  • 78% reduction in man-hours

In aviation, there are extreme egos in all aspects. My advice to those using VIBS is to either have someone with no experience use it, or if those with experience in vibrations to swallow their pride and use it, they will then become convinced there is nothing that can do better.

What you will see is the following — less adjustments, and fewer flights and ground runs.

Mechanics will will have less work repairing and pilots will have less FCF time and more reliable aircraft availability.

Owners will be happy because of the cost savings they will see over time.

The more you use the system, the smoother the aircraft. It doesn’t matter what you use to gather the vibration information, it’s the solution that matters.
