MISSION
Korean aerospace engineering is world-class.Access to the global market is not.Aerocharis exists to close that gap.
WHO WE ARE
Aerocharis is a Seattle-based aerospace strategy and engineering consultancy working between Korea and the broader global aerospace ecosystem. We help Korean aerospace, avionics and materials companies understand what U.S. certification and OEM supply-chain entry actually require, and translate that into a practical, sequenced plan. Our work spans engineering assessment, certification strategy, and the relationships needed to open a serious conversation with an OEM or program office.
JOSEPH H. LEE
Founder & CEO
Joseph H. Lee brings more than two decades of experience across engineering, R&D, aircraft systems, and international aerospace programs. His career spans aerospace engineering at Boeing and principal-investigator leadership of Korean national R&D programs, and he works between Seattle and Seoul.
ENGINEERING BACKGROUND
Aerocharis's engineering practice centers on aircraft systems, hardware development, simulation, and flight-test preparation, together with certification disciplines including DO-160 environmental qualification, DO-178C software assurance, and DO-254 hardware assurance.
- Aircraft systems
- Hardware development
- Simulation
- Flight-test preparation
- Certification (DO-160 · DO-178 · DO-254)
These are areas of active engineering practice, not a record of specific completed programs.
GLOBAL PERSPECTIVE
Aerocharis works across Seattle, Seoul, and the wider aerospace ecosystem that connects them. An OEM's internal engineering and supply-chain logic, and a Korean supplier's real operational constraints, are rarely understood together — usually only one side or the other is. That combination, not either alone, is what actually shortens the distance between a capable Korean company and a serious OEM conversation.
WHY AEROCHARIS
ENGINEERING FIRST
Guidance grounded in how OEMs and certification authorities actually evaluate a design, not generic consulting frameworks.
BOTH SIDES OF THE TABLE
Built from experience inside a major OEM and inside Korean national R&D programs — not from one side only.
SEQUENCE OVER VOLUME
The goal is not more paperwork. It's finding the right order to clear the gates ahead of you.
NO PROMISED OUTCOMES
We help you understand and prepare for certification and supplier-qualification requirements. We do not, and cannot, guarantee any certification or qualification outcome.
