Air Comm Engineering Leads the Industry

As the premier leader in aviation heating and cooling systems, Air Comm’s technical staff is comprised of aerospace, mechanical, structural, electronic and software engineers who each bring a unique set of talents and expertise in order to develop state of the art systems for fixed wing aircraft and helicopters.   To ensure ACC meets all required certification compliance regulations, ACC employs a full-time certification engineer and a Designated Engineering Representative (DER) of the Federal Aviation Administration (FAA) to coordinate all major and minor certification efforts.   Our engineering staff is supported by certified SolidWorks Professionals with over 40 years of combined design and drafting experience.  ACC uses Solidworks and Autodesk Mechanical Desktop design software with a controlled Enterprise Product Data Management (EPDM) vault system for maintaining configuration control throughout the release cycle process.   Both of these software platforms easily interface well with other CAD systems such as CATIA via . stp files.

​

In addition to the expert engineering staff, ACC works with a number of consultants who specialize in the fields of Finite Element Analysis, Reliability and Predictions Analysis, Computational Fluid Dynamics Analysis, Stress and Strain Analysis, and Lightning and Direct Effects Substantiation.   

ACC’s staff of project management professionals ensures each project is delivered on time and within budget.

ACC Heaters are State-of-the-Art

 

In 1987, Air Comm introduced the “mini-ejector” bleed air heater revolutionizing helicopter cabin heating systems.   For the first time, operators could rely on a single light-weight, low-cost, maintenance-free system to provide ample heat regardless of the operating environment.  ACC heaters have been field proven to -40°F and today are found on more than a dozen different types of turbine helicopters operating from Yukon, Canada to Antarctica.

​

This advanced-technology system is engineered to provide optimal output at less than cabin ambient noise levels.  It consists of a series of miniature heater ejector assemblies strategically located to provide comprehensive heat and defog coverage throughout the aircraft.  Simple and elegant, the system delivers warm air where needed without the use of blowers and air distribution ducting.

 

ACC Electric Heaters

 

ACC looks to continually improve its existing systems and has developed ceramic heater modules with integrated brushless blowers.  Unlike traditional heating elements that use an exposed nichrome resistance wire or metal rod elements to generate heat, ceramic PTC heating elements have unique characteristics and act as semiconductors. The composition of these elements results in a temperature dependent resistance wherein, when the ambient temperature starts to decrease, the heater’s resistance will decrease, drawing more current and countering the cooling tendency. Conversely, any tendency to increase its temperature has the opposite effect. The net result of this behavior is that the heater element has a maximum temperature limit and is self-regulating.  Not only is this system efficient, the system modules allow for multiple configurations providing balanced heating throughout the aircraft.

ACC Air Conditioners Set the Industry Standard

 

Like ACC heater technology, a similar design philosophy focusing on high performance, light-weight and low cost is applied to Air Comm helicopter air conditioners.  All ACC air conditioners are vapor-cycle systems which are either mechanically or electrically driven that provide excellent aircraft cooling by locating evaporators in cockpit and cabin.

Air Comm air conditioners are renowned for efficient, effective, trouble-free performance in all climates.  ACC systems are in service worldwide, including the Middle East, Southeast Asia, Central and South America.
