Boeing and MIT Team Up to Enhance Lightning Protection for Future Aircraft

Boeing and researchers from the Massachusetts Institute of Technology (MIT) are teaming up to develop new ways to protect future aircraft from lightning strikes. The collaboration focuses on a physics-based approach to improve lightning protection zoning and certification, especially for next-generation aircraft designs that move beyond the traditional tube-and-wing configurations.

Their latest study, published in IEEE Access, was led by MIT doctoral student Nathanael Jenkins and MIT professor Carmen Guerra-Garcia, alongside Boeing experts Louisa Michael and Ben Westin. The team created a model that predicts where lightning is likely to strike an aircraft and how it might spread across the surface afterward. This information helps create zoning maps that identify areas needing enhanced protection, using computational fluid dynamics, electrostatics, and lightning sweep simulations.

Traditionally, aircraft lightning zones have been determined through years of flight experience and post-strike inspections. However, Boeing and MIT aim to shift toward a more physics-driven method that can support new aircraft designs earlier in the development process. The team validated their approach on a conventional aircraft and found that the physics-based zoning maps aligned with industry standards, giving Boeing confidence in the method's potential for future aircraft concepts, including blended-wing and truss-braced designs.

Lane Ballard, Boeing's Chief Technology Officer, emphasized the value of industry-academia collaborations in advancing aircraft design, certification, and safety. Guerra-Garcia highlighted the decade-long partnership between MIT and Boeing, combining fundamental research with practical engineering solutions. This research is part of Boeing's broader effort to address real engineering challenges as the aerospace industry evolves toward more efficient, sustainable, and high-performance aircraft.
