Acorn Welding Ltd has received STC approval from Transport Canada on new, next generation exhaust stacks for the DHC-6 Series Twin Otter Aircraft. This STC utilizes modern streamlined exhaust stacks developed in house by Acorn Welding that have been optimize for maximum recovery of loss from the PT6A family of engines.
Equipping the DHC-6 Series Twin Otter with a modern next generation exhaust stack allows the aircraft to better utilize jet thrust generated by the PT6A-34 Engine. The PT6A-34 engine generates the 82 pounds (lb) while the -27 generates 90 lb of jet thrust. This jet thrust more than offsets any additional drag created by the exhaust while directing hot exhaust and combustion biproducts away from the leading edge of the wing. This re-direction of the exhaust is expected to keep the aircraft cleaner during operations. A major benefit to operators will be a reduction in maintenance resulting from less sooting and corrosion of the exhaust gasses to the wing.
The new next generation exhaust installation is lighter than the existing DHC-6-400 series exhaust in service today. It is also constructed without the use of turning veins to redirect the exhaust rearwards. The complete Inconel 625 construction will solve the engine flange corrosion problem that exists for those operators operating in highly corrosive salt-water environment. With over 1050 classic DHC-6 exhaust stacks delivered since 2006, and countless repairs, Acorn Welding is looking to the future by modernizing the DHC-6 Fleet.
The next generation DHC-6 exhaust is the latest addition to Acorn Welding’s portfolio of turboprop exhaust products. In addition to the DHC-6, Acorn Welding manufactures aftermarket exhaust for the Beechcraft King Air 200, 250, 300, and 350 series of aircraft as well as the 1900 and 1900D airliner. Other turboprop products include process repairs for Beechcraft Anti-Ice intake lips, engine trusses and Cessna 208 Caravan exhaust secondary exhaust assemblies.
