Building Wire Harnesses Right

Some of the most important elements to the electrical and electronic functions of aerospace vehicles are the cable and wiring harnesses. Accurate transmission of control and data signals is heavily dependent on the cable reliability, wiring harnesses, and connectors. Best design and maintenance practices are crucial to their longevity and reliability. Eliminating stresses to the […] Read more

How to identify an aircraft wire or cable

If you are trying to identify an aircraft wire or cable, you may want to take advantage of the lessons Lectromec has learned in the past three decades. Because we are in the business of evaluating electrical systems, we frequently open up boxes where we must determine origin and manufacturer of wire and cable. This […] Read more

What does an aircraft wire testing lab look like?

It is quite possible many aerospace professionals have never seen the inside of an aircraft wire testing lab. If you haven’t had a chance to see our lab, here we present a quick tour. Read more

Understanding unexpected arc track resistance test results

Lectromec has been testing wire for the past thirty years. We have seen nearly every conceivable variation of aerospace wire testing. Some tests are straight forward and require little or no additional explanation of the test results; other tests require a fair bit of explanation to understand the test itself and what the results mean.

What is the impact of increased electrical loads on aircraft wire systems?

With More Electric Aircraft (MEA) being the big push in the industry, it is important to take a moment and think about the wiring system that is going to be supporting these new designs. The following are some of the consequences resulting from an increased electrical load on the aircraft wire system: How much wire […] Read more

Aircraft secondary harness protection with Gregg Turcich

Today Gregg Turcich sat down with Lectromec to discuss the topic of aircraft secondary harness protection, or what some call aerospace protective sleeves. Gregg is certainly qualified to talk about these topics because he has a degree in chemical engineering and decades of experience in aerospace technology. Gregg enumerates the four kinds of protection that […] Read more

Effects of high voltage on aircraft wire connectors

One of the challenges that exist in modern aircraft design is performing more with less. That means using less space, less power, and less weight. For the most part, the technologies integrated into aircraft systems have been able to achieve these goals. Along with this push is a drive to place higher voltages on electrical […] Read more

Aircraft solid state power distribution with Fred Potter

Today’s interview is with Fred Potter, Chief Engineer at Astronics AES. He has worked in complex engineering projects since he got his bachelors of science in electrical engineering from Rutgers University-New Brunswick. During the discussion Fred uses his decades of experience in electronics, systems engineering, and engineering management to talk about aerospace wire system technology. […] Read more

Introduction to aircraft electrical power distribution systems

The trend in modern aircraft design is away from mechanical systems (hydraulics, pneumatics, etc.) and toward electrical components, or Aircraft Electrical Power Distribution Systems. There are several benefits of the modern design (particularly weight savings). However, as with any airplane design, no system can be fielded before it can be proven safe, reliable, and able […] Read more

Aircraft wire inspection? Time tested guidelines

Performing routine aircraft wire systems visual inspections is a critical aspect of maintaining aircraft airworthiness and extending the component lifecycle. A visual inspection is the first step in assessing the condition of a component or determining what future steps need to be taken. This article discusses recommended techniques based on MIL-HDBK-522, which provides EWIS inspection […] Read more
