Binary Actuating Technology to reduce jet aircraft noise and toxic emissions

Keywords: Aircraft, Emission

Quieter and more environment-friendly aeroplanes could soon become a reality, as Camcon Technology unveils a technology to reduce jet aircraft noise and eliminate toxic emissions.

Camcon reports that it is currently developing a prototype valve to reduce toxic emissions and improve the efficiency of jet aircraft by controlling how fuel is injected into the combustion chamber.

In experiments at the Berlin Technical University, Camcon Binary Actuation Technology (BAT) valves are reported to have reduced the front-end high-pitched noise emitted by jet engine blades by more than 20 dB at critical frequencies.

The technology also claims the potential to reduce the exhaust component of rear jet noise by actively modulating exhaust gases and combining them with the air, to reduce the “roar effect” vortices immediately behind the engine.

The European Advisory Council for Aeronautic Research has set targets of reducing perceived noise to one half of current average levels, 50 per cent reduction in CO₂ emissions per passenger per kilometre, as well as 80 per cent cut in nitrogen oxide emissions by 2020.

“The EU regulations have put a lot of pressure on the aviation industry to cut noise and toxic emissions pollution”, said Ian Anderson, CEO, Camcon Technology. “Our research leads us to believe that Camcon’s Binary Actuating Technology can offer the industry the answer to this continuously escalating problem”.

The high-speed, low energy consumption and long life characteristics of the Camcon binary actuator is set to have a considerable impact in a number of industries.

In addition to the specific application being developed for the aviation industry, the technology is appropriate in other areas including gas and liquid flow control, remote location and sub- sea oil services, automotive engine control and noise pollution reduction in the aviation industry.

Camcon’s binary actuator fundamentally differs from the traditional valve designs. Using high power permanent magnets and a spring- loaded armature the configuration requires a very short electrical pulse to disrupt the magnetic field, causing the armature to switch from one stable position to another, thereby opening or closing the valve. No electric current needed to maintain the on or off position, creating a unique opportunity to drive even multiple valve systems from a local battery allowing precise and programmable delivery of any gas or fluid.

Based in Cambridge, UK, Camcon Technology is a small fast growing company focused on the research and development of the Camcon Binary Actuator. Camcon Binary Actuating Technology has been 15 years in development and is the invention of Camcon founder Wladyslaw Wygnanski. The high-speed, low energy consumption, low heat dissipation and long life characteristics of the Camcon Binary Actuator mean that it has applications in a whole new range of areas, as well as being a replacement for existing actuator and valve technologies.

Camcon Technology licenses its technology to customers, typically on a field-of-use basis. The company develops pre-production prototypes for customers on a consultancy basis and then hands over designs either to its customers to manufacture in volume, or to a manufacturing partner.
