High Performance Exhaust Systems for Light Sports Aircraft

  • Increased Power, more RPM, More Thrust
  • Reduced Noise Levels
  • Reduced Exhaust Gas Temperature

Developed jointly by ACME Aero Fab and Quiet Technology Aerospace (QTA), the SUPER Q combines the technologies of the two companies to produce this unique exhaust system. Based on a combination of a high performance exhaust system, matched to the ‘Hush Kit’ technology of QTA the system provides increased power, lower noise levels and lower EGT.

First flight tests have confirmed that the system provides increased performance:

  • Shorter Take Off Distance
  • Improved Climb
  • Reduced Fuel Burn in Cruise

The flight tests have demonstrated that the system dramatically reduces the perceived noise level (dBA) during takeoff and when the aircraft passes overhead. One observer stated, “that’s got to be at least half the noise level”. Static testing had shown the noise levels to be significantly lower, the flight tests have confirmed that the “Ram’ effect of the aircrafts forward motion adds to the efficiency of the noise suppression system, and provided even lower noise levels. This is consistent with other QTA programs using the same technology.

The noise suppression system is based on technology developed by QTA in producing hush kits for turbo jet powered aircraft, the company’s latest product equips the Gulfstream GII/GIII series of aircraft to bring them into compliance with Stage 3 noise regulations. The QTA system is based on there being ‘Zero’ back pressure in the silencer so the system enhances performance.

The Silencer is matched to an exhaust system developed by ACME Aero Fab, which is based on a history of producing high performance race cars (NASCAR). ACME Aero Fab also produce wing structures and shock absorber systems for light sports category aircraft.

POWER PLANT AND AIRFRAME

The system under going flight tests is designed for installation on the Rotax 400 series family of engines, and thru simple ‘tailoring’ of the header system and attachment brackets, it can be easily adapted to fit almost any airframe.

Similarly, the ‘technology’ is scalable and can be sized to provide the same benefits on other power plants.

SUMMARY OF TEST RESULTS

PROGRAM STATUS

The Super Q design has been validated and is now undergoing rigorous reliability and performance testing ahead of production release.

Production units will be available in 2016, following conclusion of the test program and the units will be on display, both static and flying at the EAA Oshkosh Show in 2016.
