Lightning Protection of Aircraft
This four and one-half day course has been presented in person at Lightning Technologies in Pittsfield, Massachusetts since 1984. They will be continued virtually via Zoom until the COVID-19 crisis has passed, when they will be resumed in person.
Lightning Protection of Aircraft is a four-and-one-half day course to familiarize aircraft design and certification engineers with the interaction of lightning and static electricity with advanced technology aircraft. The course begins by bringing the student up-to-date with the fundamentals of lightning and aircraft interaction and the possible effects of lightning on structures and systems. This is followed by a thorough review of applicable regulations, advisory material and standards. Students will learn the basic approaches and techniques of protection design and certification for both new aircraft and for modifications and upgrades, and the certification process. This course applies to commercial and military aircraft and helicopters of all categories. Major emphasis of the course is on protection of conventional and composite structures and fuel systems. An introduction to protection of electrical and avionic systems is also provided.
This course has been designed to give students the practical information and basic understanding required for meaningful work in this technology and to avoid common pitfalls such as design oversights, misinterpretation of requirements, standards and costly mistakes. The course has been developed by engineers currently active in the lightning protection design and certification of the world’s most advanced aerospace vehicles and systems.
Students interested solely in electrical/avionics topics may take only the “Avionics” course and are not required to take the “Aircraft” course beforehand. Likewise, those who are involved more in the whole aircraft situation may find that there is sufficient coverage of avionics issues in this course so that they may not need to take both courses. There is about a 10% overlap.
Students should have experience with some of the following: design of airframes, propulsion systems, electrical and avionics systems or other on-board components or systems. A degree in a related technical area is advisable but not required. Students should be conversant with design techniques and should be actively engaged in the planning, design or certification of new aircraft or components.
