Champion Aerospace is preparing for the age of the More Electric Aircraft (MEA) or All Electric Aircraft (AEA) by transforming its highly pedigreed 28VDC Transformer Rectifier Unit (TRU) to a 270VDC or 540VDC Power Supply system to support operation of new electromechanical equipment that will replace traditional pneumatic or hydraulic power. This operating voltage provides improved electrical efficiency, drives lower aircraft weight, improves aircraft safety/reliability and provides positive environmental impacts. 270VDC is accomplished by rectifying the traditional 3 phase 115VAC 400Hz line-to-line voltages via typical AC-DC conversion methods that meet requirements of MIL-STD-704.

270VDC Power Supply Key Design Parameters:

Voltage Regulation: 270 Volts DC (260-280 Volts DC)
Min/Max Normal Transients: 250/280 Volts DC at 40ms
Ripple Voltage: 6 Vpk maximum
Cooling: Self-cooled (Fan or Blast Air) or Free Convection Cooled Versions
Power: 270VDC Typical Range for aircraft applications is 5 to 450 amps; MEA applications could be considerably higher power.

The 270VDC Power Supply may also be used in conjunction with a 270VDC Uninterruptible Power Supply (UPS) attached to the bus for critical mission equipment affected by AC bus transfers, low voltage sags, and other AC/DC interruptions. This allows utilization equipment to maintain full operational capability and “ride through” these interrupts. The device can also provide transient voltage surge suppression during harmful high voltage transients to prevent catastrophic system failures. This UPS device is compatible with all power converters and plays a vital role in preserving the life of utilization equipment.

270VDC UPS Key Design Parameters:

Output Voltage: 270 Volts DC (250-280 Volts DC)
Cooling: Self-cooled
Disconnect Time: 70 Seconds
Disconnect Voltage: 230 Volts DC

Conventional wisdom says that unregulated TRUs are unable to provide “clean”, low ripple and stabilized voltage whereas regulated TRUs (RTRUs) resolve these concerns with a “tight regulation”, but this is not the case as revealed here. The latest Champion Passively Controlled Transformer Rectifier Units (PCTRU) provide superior voltage stabilization for transients and ripple voltage simultaneously. Data shown here reveals the differences in these converters allowing technical decisions to be made with respect to the different topologies available. The PCTRU is available in existing designs from 50 to 300 amperes.

High Voltage Transients
High voltage transients are generally understood as “life altering events” for utilization equipment containing semiconductor devices. Nearly all advanced electronic utilization equipment contains semiconductors that are susceptible to these high voltage transients. High voltage transients greater than 40 Volts are known to cause equipment to fail catastrophically, and/or prematurely, resulting in the loss of avionics and increasing maintenance costs.

Champion’s PCTRU incorporates transient voltage surge suppression to keep high voltage transients under 40 volts. Champion’s PCTRU suppresses high voltage transients without using active feedback inherent to Regulated TRUs. This transient voltage surge suppression method protects utilization equipment without adding a high steady state failure mode associated with Regulated TRUs.

Competitor’s Regulated TRU

Ripple Voltage
Ripple voltage is defined as the variation of voltage about the steady state DC voltage during steady state electric system operation. Many TRUs being installed on aircraft today produce ripple voltage greater than 1.5Vpk-pk. This generates significant concerns with the overall system integration with regards to electronic system faults, compatibility, and performance degradations in advanced electronic systems. High ripple voltage (greater than 1.5Vpk-pk) can have a “poisoning” effect on equipment causing it to degrade over time.
Champion Aerospace’s simple passive techniques in the PCTRU provide a typical ripple voltage of 0.20 Vpk-pk (shown below) which is a 90-95 percent improvement beyond competitive aircraft power supplies.

Champion Aerospace manufactures a broad range of high-performance inductive or capacitive discharge ignition exciters in configurable, customer driven designs. Compared to automotive or aviation reciprocating ignition systems, the spark energy discharge of a turbine ignition system is significantly larger- In some cases, the spark is over 100 times higher energy than the spark in an automobile or aviation reciprocating engine.

Champion offers traditional spark gap technology in legacy products, but has transitioned to pioneering designs solely utilizing solid-state technology incorporating our patented multi-voltage “Spider Switch” or new (patent pending) Solid State Spark Gap (S3G) design to maximize reliability, efficiency and capability while minimizing weight. The S3G is a newly introduced concept that is virtually a “plug and play” device into legacy or new applications requiring radiation-free assemblies.

For those customers using radiation bearing exciter designs, note the Champion product is not considered hazardous for use and meets exemptions criteria established by NRC and EURATOM. These exemptions define our exciters are REACH compliant. See Champion Exciter Compliance to NRC-REACH-EURATOM regulatory requirements information paper for further details.

Champion Exciters are widely used in the following aero engine applications:

Honeywell: HTF7000*, 131-9 Series, HGT 1700, TPE331, AS907, ALF502, LF507, 331-600
Pratt & Whitney Canada: PW150*, PW206*, PW307A/B*, PW308A/C/C+*, JT15D, PT6 Series*, PW207*, PW814/815*, APS2300*

Product Highlight- Pratt & Whitney Canada PT6 Exciter
Champion designed and manufactures the OEM select exciter for the largest turbine fleet in the aerospace industry. The Champion CH92106-1 PT6 exciter, utilizing two fully redundant ignition channels, is able to offer a lighter weight, higher energy, easily reparable and more reliable solution than is offered with the competitor’s exciter. The solid-state switch that discharges the spark event is designed with the latest solid state technology and is not a life limited component like the competitive unit radioactive spark gap.
Champion CH92106-1 exciter benefits include:

  • Higher spark rate for reliable starts under all conditions (a 3-spark per second solid state ignition system compared with the current 1-spark per second for 10-381550-4)
  • 1.2 joules of energy per second to light the engine (compared to 0.7 joule per second for 10-381550-4)
  • Tested in 2009 to the current OEM temperature and vibration requirements
  • Non-Radiation bearing exciter; solid state components provide the energy (no spark gap)
  • Painted with high temperature paint for corrosion protection
  • Un-potted design for improved reparability

The unit has FAA-PMA approval based on Identicality and it carries an OEM part number on the label (3043937-04).
Champion Aerospace manufactures ignition exciters, some of which contain a small amount of radioactive Tritium gas in the high voltage-switching component (referred to in this document as a “Spark Gap”). Spark gaps have been used in turbine engine ignition systems on aircraft since the 1940s, and are simple and reliable high voltage switches. They do require a small dose of radioactive gas in their construction. The fundamental issue is that a radioactive isotope is required to maintain a consistent spark gap ionization voltage over the unit’s operating life. Without the small amount of tritium gas in the spark gap, the ionization voltage of the gap can vary significantly over time and result in a potential decrease in the delivered energy of the exciter. There is no alternative material that Champion can propose for use in our spark gaps that is more benign that Tritium. Competitive comparative spark gaps utilize the less environmentally friendly Kr-85 isotope.

Although the basic elements of every gas turbine ignition system are the same, even the sophisticated observer has trouble delineating amongst the various types. Actual performance, design types, and the physical appearances of most turbine-powered aircraft ignition systems differ from application to application. Engine operational requirements, combustor designs and performance parameters, operating environments, mounting considerations, FAA requirements, and differing design philosophies associated with providing reliable ignition are just a few of the reasons for the many models of turbine engine ignition systems in service today.

Champion Quality and Reliability.
Every Champion Aerospace exciter carries our full warranty and is backed by the Champion name. Our exciters are built to the same exacting standards that have made us a leader in aviation products for over 75 years.
Though more reliable, today’s turbine ignition systems are also more complex, requiring that aircraft technicians possess a higher degree of knowledge and understanding of turbine ignition system theory. Familiarity with a few basics will enable technicians to develop proper insight into standard operation, troubleshooting, and maintenance practices.

Aircraft ignition harness assemblies prevent the entrance, formation, and accumulation of impurities within the shielded distribution systems universally employed on airplanes using high-sensitivity radio receivers.

Champion Slick ignition harnesses feature corrosion resistant connections, a heavy-gauge contact spring to provide more contact area and force against the spark plug contact, plated ground path overbraid and a center conductor wire design that provides flexibility to reduce fatigue and breakage of the specialized plated stainless steel coiled conductor core from repeated temperature cycling and engine vibration. Fluid susceptibility concerns are addressed by the silicone based sheathing that protects the ignition wire from spark plug termination to the harness backplate. This extremely flexible wire lends itself to sharp bends, thereby eliminating the need for old style harness elbows. There are no soldered joints in the grounding circuit, and they are custom made for most 4 and 6 cylinder engine applicatinos using Slick magnetos. Harnesses for Slick magnetos are furnished with the backplates installed.

FAA-PMA approved Slick Harnesses by Champion are built to handle the demanding environmental conditions, maximum spark energy produced and maintain optimized levels of electromagnetic Interference protection. Using anything less could result in more than a 50% reduction of radio sensitivity in commonly used communication frequencies, as tested by Champion.

  • Full one year or 500 hour new part warranty on Slick components
  • Over 100 years of aviation ignition manufacturing experience
  • All manufacturing and customer service based in the USA
