The Lectromec Podcast

The purpose of the Lectromec Podcast is to keep you informed of trends in the rapidly changing aerospace industry. Once a month we interview leaders and seek their insight on topics related to Electrical Wiring Interconnection System (EWIS), wire testing, and risk assessment for aerospace.

Electric Aircraft Design Considerations 06/01/2021

Electric Aircraft Design Considerations Electrical energy storage has reached a point where it is possible for the manned vehicle propulsion to use non-petroleum based energy. To achieve this goal, it has required a lot of research, design, and innovation that has pushed these vehicles to depend on high voltage electrical power systems and forego the use of hydraulics and pneumatics. If electrical aircraft are the aircraft of the future, what are the design factors that the EWIS community will have to address? /episode/index/show/lectromec/id/19313594

Is my Aircraft Wiring Serviceable? 07/05/2019

Is my Aircraft Wiring Serviceable? This idea of serviceability is applicable to other engineering disciplines and is undoubtedly applicable to aerospace vehicles. From our perspective at Lectromec, understanding the serviceability of aircraft wiring is critical. However, to determine an aircraft wiring system serviceability state requires the limit state to be defined and assessed. Here we propose three such properties of a serviceable aircraft wiring system. /episode/index/show/lectromec/id/10418381

International Test Standards for Aircraft Wire 06/21/2019

International Test Standards for Aircraft Wire Frequently, Lectromec's articles and podcasts have focused on wire and cable testing from US-focused standards such as the SAE and US military (MIL) documents. While these are standards frequently cited, there are other standards organizations that support the aerospace wiring community. /episode/index/show/lectromec/id/10240796

Replacing Old Aircraft Wire 06/11/2019

Replacing Old Aircraft Wire As aircraft age, it is natural to contemplate the aircraft condition as to how much longer the equipment can be maintained. Typically, after the engines, structures, environmental control system (ECS), navigation, landing gear, interiors, flight controls, and fuel system are considered, the question will ultimately appear, “do I need to replace my wires that are 15/20/25/30 years old?” While it would be nice if there were a simple answer, like all engineering, it comes down to the evaluation of the syst /episode/index/show/lectromec/id/10121929

Selecting Coaxial Cables for Aircraft Application 12/24/2018

Selecting Coaxial Cables for Aircraft Application The transmission of electrical energy is, surprisingly, not a trivial task. At low frequencies and low power, a very primitive wire construction is possible and can be successful for extended applications. As frequencies increase, the need for focused attention becomes ever more apparent. /episode/index/show/lectromec/id/8030708

EWIS and Instructions and Continued Airworthiness 12/24/2018

EWIS and Instructions and Continued Airworthiness Aircraft are delicate creatures. They can be very finicky when not treated right and the design of an aircraft can only go so far to ensuring that the aircraft has a long, successful life. Without a doubt, many of Lectromec’s articles address the design and manufacturing phases of an aircraft’s life. As highlighted in the last article, technological and engineering hurdles must be overcome for aircraft electrical wiring interconnect system (EWIS) to achieving a fault-free life. /episode/index/show/lectromec/id/8030645

Cold Testing of Wires 10/23/2018

Cold Testing of Wires The environmental extremes under which wiring exists in aircraft can rapidly degrade materials that are not prepared or designed for those conditions. Without a doubt, high-temperature ranges that are typically considered for aircraft wiring eliminate most wire insulation types that are suitable for ground-based home applications. /episode/index/show/lectromec/id/7284347

Should Polyimide Insulated Wire be Trusted? 10/08/2018

Should Polyimide Insulated Wire be Trusted? The history of polyimide insulated wire is one that has numerous opinions and a lot of misconceptions. After several incidents involving polyimide wire in military and commercial aircraft, many within the aerospace industry refused to put any polyimide insulated wire/cable onto the aircraft they design/maintain. As is often the case with components involved in incidents, a lot of facts and myths get jumbled together. /episode/index/show/lectromec/id/7141211

25.981 is Not a Barrier 09/20/2018

25.981 is Not a Barrier The certification of an aircraft requires the expertise of dozens of disciplines coming together for a single effort. Certainly, as the electrical wiring interconnect system (EWIS) has developed over the last couple of decades, the interaction with other systems and components is becoming better understood as the requirements are becoming more pronounced. /episode/index/show/lectromec/id/7069626

DO-160, EWIS, and EMI 08/10/2018

DO-160, EWIS, and EMI From an implementation perspective, it cannot be understated how much EMI can impact system performance ranging from degraded performance to make a system completely inoperable. Thankfully, there are test methods to evaluate the susceptibility of electromagnetic interference of a wire harness design. /episode/index/show/lectromec/id/6910154

Selecting Aircraft for Inspection and Work Unit Codes 08/03/2018

Selecting Aircraft for Inspection and Work Unit Codes A couple weeks ago, Lectromec's podcast focused on Condition Based Maintenance (CBM) and discussions at the mechanical equipment and subsystems integrity program (MECSIP) managers meeting. To continue with that theme, this article focuses on two specific presentations and topics that were covered: sustainment authorization and EWIS working unit codes (WUCs). /episode/index/show/lectromec/id/6883758

Arc Fault Circuit Protection 07/24/2018

Arc Fault Circuit Protection Arc Fault Circuit Protection has been a technology that dates back to the 1990s. Despite this not being a new technology, the breath of its implementation is still limited. The device owes its inception to arcing events that occurred on in-service aircraft. Because of these events, the wiring community sought to create wiring that was arc track resistant, and the circuit protection community sought to cut off the arcing event before too much energy was released. /episode/index/show/lectromec/id/6845818

Galvanic Corrosion and Red Plague 07/16/2018

Galvanic Corrosion and Red Plague Any concept that has earned the word “plague” in its name is certain to be an infamous hassle. The “Red Plague” of the aerospace industry is no exception. For decades, the plague has been identified with corrosion impacting the performance of silver-plated copper conductors. /episode/index/show/lectromec/id/6816069

Condition Based Maintenance and Risk Quantification 07/05/2018

Condition Based Maintenance and Risk Quantification Aircraft maintenance is usually broken down one of two ways: by physical zones or by systems. The mechanical equipment and subsystems integrity program, also known as MECSIP, is the US Air Force’s approach to addressing aircraft sustainment and maintenance through focused system evaluation. In June, Air Force MECSIP managers gathered in Dayton, Ohio to discuss the latest developments, procedures, and technologies for addressing the MECSIP needs of their fleets. /episode/index/show/lectromec/id/6777305

Dielectric Constant and Wires 06/25/2018

Dielectric Constant and Wires A good wire insulation is more than just preventing electrical energy from leaving the conductor; there are dozens of properties that are important to its performance and usability. One of these that is easy to overlook is the wire’s dielectric constant. /episode/index/show/lectromec/id/6741430

What is an aircraft service life extension program? 11/09/2015

What is an aircraft service life extension program? Over the years the Lectromec website has received thousands of visits. If you look at the most popular articles, the ones that deal with Aircraft Wire Service Life Extension Programs are among the most popular. Because of this popularity, the Lectromec Podcast sat down with the president of Lectromec, Michael Traskos, to talk about Service Life Extension, or SLEP. /episode/index/show/lectromec/id/3932610
