More performance. Less fatigue.

Better Performance Starts With Better Technology

Dual Tailboom Strakes are the most cost-effective, multi-functional, value-added modification ever developed for single-rotor helicopters with enclosed tailbooms.

They work by organizing and controlling rotorwash, reducing undesired sideways lift on the left side of the tailboom. By reducing turbulence under the tailboom, Dual Tailboom Strakes reduce tail rotor pedal reversals by up to 38 percent.

Fly with new levels of control and authority. Installing Dual Tailboom Strakes on your helicopter is an investment in safety, productivity and the one thing money can’t buy – peace of mind.

How It Works

The main rotor of a helicopter accelerates as it goes around a curved tailboom. This accelerates airflow and results in increased pressure that acts against the boom, causing a force disadvantageous to controlling the helicopter. BLR Dual Tailboom Strakes provide unprecedented levels of stability, control and safety by reducing undesired lift.

Read what our customers have to say about Dual Tailboom Strakes

null
“We were the first Canadian operator to install Dual Tailboom Strakes, and we had great success with them right off the bat. We noticed an increased payload in our heli-logging work.”

– Jason Evans, Chief Pilot, Wildcat Helicopters

null
“The BLR Tailboom Strake has been an excellent purchase, we found that they’ve paid for themselves very quickly in our heli-logging operations, and there’s been a significant decrease in maintenance costs to the tail rotor and tail rotor drivetrain.”

– Mike Michaud, Owner, Wildcat Helicopters

null
“BLR has been excellent as far as any type of performance mods that we have done – especially the Strake. That has been an excellent modification to extend the life of the aircraft, and we really appreciate everything they’re doing.”

– Ray Newcomb, President, JBI Helicopter Services

null
“We found that we have definite increased performance out of the tail rotor authority. We no longer are necessarily riding left pedal stops all the time – particularly in our high-power demand situations where we’re trying to do a spot-drop or going into some tight water dip sites. We feel much more in control of the aircraft.”

– Dave Adams, Pilot, Washington State Department of Natural Resources

null
“I believe that the Strake system not only takes pilot workload off, but obviously [gives us] a better piece of mind when we’re out there flying knowing that we’re flying something that’s safer.”

– Glen Giammalva, Pilot, Washington State Department of Natural Resources

null
“When you don’t have to put in all that pedal to get the helicopter to do what you want it to do – that makes my job a lot easier.”

– Jerry Gray, Pilot, Hi Line Helicopters

null
“Fatigue in helicopters is an ongoing battle — tailboom fatigue in this particular model is a high priority. We do have to reduce that in order for this helicopter to operate safely. And utilizing the tail rotor more efficiently, utilizing less horsepower going to the tail rotor to counteract the main rotor torque is going to reduce fatigue and, therefore, increase safety.”

– Darin Hunter, Director of Maintenance, Hi Line Helicopters
