The industry has known the Fastfin is good thing for a while now. Nice to finally see some published data supporting the mod. :up:

 

 

FAA APPROVES BELL 212 HELICOPTER FLIGHT MANUAL SUPPLEMENT, INCREASING PERFORMANCE WITH BLR AEROSPACE FASTFIN SYSTEM

 

 

 

EVERETT, WA, October 20, 2011 – BLR Aerospace, a name synonymous with outstanding performance enhancement technologies that increase the capabilities of rotary-wing and fixed-wing aircraft by manufacturers such as Bell Helicopter and Hawker Beechcraft, today announced an FAA-certified performance increase for its Bell 212 FastFin® System.

 

 

 

The FAA has approved a Flight Manual Supplement (FMS) certifying up to 500 pounds of additional out-of-ground effect hover performance for Bell 212s equipped with FastFin. The same approval is expected soon from the European Aviation Safety Agency (EASA). With the FastFin® System, most Bell 212 operators will increase their useful load between 10% and 15%.

 

 

 

“Helping the Bell helicopter community fly more productively and more safely is a priority for BLR,” said Dave Marone, BLR’s vice president of Sales and Marketing. “The FastFin® System clearly delivers the performance benefits operators need and want.”

 

 

 

Installation of the FastFin® Tail Rotor Enhancement and Stability System kit involves modifying a helicopter tailboom with two parallel strips (known as Dual Tailboom Strakes), and reshaping the vertical fin to optimize airflow around the tailboom. This field installed kit delivers a range of important benefits to operators who fly the modified aircraft.

 

 

 

More than 75 FastFin® Systems have been sold for Bell 412 helicopters since the system was FAA certified in July 2010, and EASA certification is imminent. The system’s advantages — including up to 1,250 pounds of additional in-ground effect hover — are so strong that Bell Helicopter has made the FastFin® System standard on new Bell 412EPs.

STICKJIGGLER,

You will get to try out a FastFin this winter

[STICKJIGGLER]

:up: SWEET :up:

Although it's going to be tough to beat the "Heavy Lifter" I'm used to driving :punk:

[NG Limited]

Wild ride :up:

 

Here is the tail of your ride this winter

[STICKJIGGLER]

Nice, :up: I can't wait to try those "Speed Holes" out. Thanks Ng, Cheers

By taking off some of the skin back there, does it mean you can take out some of the lead in the nose?

 

Some weight saving here perhaps?

the weight is probably offset by that little extension they have of the end of the boom

[Over-Talk]

I believe the missing skin had to be replaced by a few pounds of ribs etc......

(plus the strakes that run the length of the tailboom).

 

Therefore the Fastfin is slightly heavier than the standard pylon.

...but because it is so far aft, they have to compensate with quite a bit of lead in the nose.

I heard the completed Fastfin Kit adds about 20 lbs to the empty weight.

(but the HOGE may increase by about 500lbs depending on altitude/temperature).

 

Is that correct?? NG do you know??

That is pretty much bang on with my experience so far. With the first 3 aircraft converted, one needed 2 lbs of weight in the nose and one about 16 lbs in the nose. The third aircraft was somewhere in between. If your aircraft already has a strake kit installed there won't be much of a weight change with the addition of the Fastfin.

 

The HOGE does improve depending on density altitude but the WAT chart remains the same.
