Avionics

More electric and all-electric aircraft projects along with variable frequency generation systems are driving new developments and new test needs in the fields of avionics.

CINERGIA offers a unique Regenerative AC Electronic Load designed to work in a frequency range of 360 to 900Hz used mainly in aircraft generator’s testing platforms. The use of such equipment has two main advantages. First, it allows a significant energy and power saving as > 90% of the energy is fed back into the grid. Being, many times, the power saving the most important point as the power requirements of the laboratory will be reduced to the losses of the motor-generator bench plus the losses of the electronic load. Second, it allows a better control and simplifies hugely the tests...

... Common test procedures require loading the generator with a fixed power factor (cos fi) while the speed of the generator changes (and thus the frequency). This requires adapting the inductance value continuously in order to keep the cos fi constant throughout the frequency sweep. Using real inductors demands the use of many inductors, that will be connected/disconnected to modify the inductance, or the use of inductors with variable gap. With CINERGIA High Frequency Electronic loads it is only necessary to set the desired current and delay (cos fi) and the dynamic PLL will automatically synchronise the current with the voltage keeping the power factor fixed.

Avionics Power Standards Compliance Testing

As aircraft electronics continue to evolve, so do their power requirements. Aircraft systems have grown from their original 115Vac L-N / 208Vac L-L at 400Hz fixed frequency roots to sophisticated on-board power systems operating at 115Vac and 230Vac and frequencies ranging from 360 to 800Hz.

Commercial avionics tests standards such as DO-160 and EuroCAE 14 have a wide range of AC power immunity tests that have to be performed on airborne electronics. More recently, several commercial aircraft manufacturers have developed their own version of these test standards based largely on DO-160.

Military aircraft electronics have to comply with standards such as MIL-STD-704 or MIL-STD-1399-300B. These standards evolve along the same lines as commercial standards. Pacific Power Source’s products have grown from the capability to power aircraft electronics at 115Vac and 400Hz to full AC Power Compliance Test Systems today. Advanced Windows control software manages test sequences and provides documentation on product conformance.

Switching and simulation systems for aerospace and defense applications Pickering appreciate that aerospace & defense electronic engineers have unique testing needs driven by requirements for long operating life, high reliability and hostile environmental conditions. We understand that to design, deploy and sustain your test system can be challenging. We offer PXI, PCI, LXI & USB modular switching and simulation products and services to help your engineering team get the job done on time and budget, and we support our products for 15 to 20 years or longer. We have produced Switching and simulation systems for aerospace and defense applications since 1988.

Products designed for aerospace and defense applications include:

  • General Purpose switching
  • Fault Insertion for Hardware-in-the-Loop simulation
  • RF/Microwave switching up to 110GHz
  • Sensor simulation modules including Programmable Resistors, RTD, Thermocouple and LVDT/RVDT/Resolvers

When our product range doesn’t fit your application, we have the agility and expertise needed to develop a system to your specifications, often with little to no engineering cost. Our capabilities and expertise are the reasons why major aerospace and defense companies.

Aviation Compliance

In the aerospace industry, electromagnetic compatibility between installed systems poses an existential threat. For this reason, applicable legislation such as ABD0100.1.8 sets limits on harmonic currents up to the range of 150 kHz. Power analyzers from ZES Zimmer can analyze these harmonics using the LMG670 from ZES. First of all, this is possible directly thanks to the implementation of harmonics analysis, and secondly it allows for the desired level of detail through the transfer and analysis of the sampling values using external software.
