PowerFlow Exhaust Tuned Exhaust Explained
Tuning Theory
Tuning an exhaust system is critical for an aircraft engine. It is easier to tune an aircraft engine than a car or motorbike, because the range of RPM used is much narrower. The major obstacle is that space inside the cowl tends to be very scarce!
Although motorcycle and automobile racers have been tuning their exhausts for over forty years, until the late 90's, there were no tuned exhausts on certified aircraft. In order to work, a tuned exhaust must reduce the pressure at the exhaust port just before it closes, to below the pressure in the intake manifold at that time... called the overlap phase. At that moment, fresh mixture can be drawn into the cylinder and simultaneously spent gases removed from it. In an untuned exhaust, the pressure in the exhaust at that moment will be greater than that of the intake, and spent gases will remain in the cylinder or even flow backwards into the intake manifold. more » |

Northeast Husky Takes Delivery of Aviat Husky Amphib
Northeast Husky, recognizing the demand for Aviat Husky’s equipped with amphibious floats, has equipped one of their inventory demonstration Aviat Husky’s with a set of PK Floats 2250A amphibious floats.
Jeff Moody, President of Northeast Husky, said in a recent interview, “We made the decision to equip one of our inventory Husky’s with the PK Floats 2250A’s in response to the increased demand for this combination. More than half of our clients order a Husky on floats or add them at a later date and we wanted to make certain that we can provide our customers with the training and flight experience prior to their purchase of a set of floats”
The PK equipped Husky will be based at Northeast Husky’s Laconia ,New Hampshire location and will be available for demonstration flights, seaplane training and also will qualify for complex aircraft training or those seeking a commercial pilots certificate or those seeking a complex aircraft endorsement. more » |

Rosti-Fernandez Skis for the Husky
Michael Vivion
The late February light provided little contrast as I evaluated the ski landing site. What I could see did not look promising…a small, meandering stream, almost completely covered in overflow (water on top of the ice), with waist deep snow everywhere else. If there were a formula for getting stuck in a skiplane, this was it. I rolled onto final, and it occurred to me a bit ironically that this would be a great test for these new skis. more» |

Give Me Space, Hangar Lifts Double Coverage.
How would you like to cut your hangar rent in half? Or add a second airplane to your fleet
without increasing your hangar costs?
Tom Crone already owned and flew a Grumman AA1B when he came across a beautifully restored Piper J-3 Cub that he very much wanted to buy. The question was where to put it. Crone didn’t want to leave either airplane outside, subject to the Mid-Atlantic heat, cold, wind, and rain. And a second hangar was unobtainable—both in terms of ongoing costs ($400 a month) and a years-long waiting list. more » |
