Engineering, Integration & Flight Test
At the heart of Legionnaire International is an engineering and flight test team built for speed and precision. Our department runs on “Agile Sprint Methodology,” enabling us to design, develop, test, refine, analyze, build, and repeat in focused "small win" cycles turning ideas into validated hardware faster - minimum viable products are produced without cutting corners. Our engineering capabilities are powered by an industry-leading software suite:
SolidWorks — Mechanical design, FEA, and drawings
SolidWorks PDM — Engineering document control
Cameo — Model-Based Systems Engineering (MBSE)
Ansys — Computational Fluid Dynamics (CFD)
MATLAB — Data analysis
Our fleet of A-4 Skyhawks and chase aircraft is fully equipped to handle any mission required, including the integration and testing of advanced avionics, weapon systems, and pod systems for diverse applications.
Douglas A-4 Skyhawks & Chase Aircraft carry the load:
Rapid Weapons Integration & Test
Engine & Subsystem Pod Test
Telemetry Collection / Transmission
Airborne Radar, IR & Optics Test
Experimental / Engineering Systems Test
R&D Engineering
Engineering at Legionnaire closes the loop between design and flight. Our engineers take a requirement, design the system, and prove it in the air. Analysis, drawings, instrumentation, simulations and aircraft integration all occur in one team.
Advanced Weapons Design and Development
Specializing in the creation of sophisticated air-to-air and air-to-ground missiles, focusing on enhanced targeting accuracy, longer range, and increased lethality.
Onboard Pod Systems Development
Designing and integrating state-of-the-art EO/IR, INS, GPS systems, optimized for navigation, targeting and engagement
Electronic Warfare and Countermeasure Systems
Crafting electronic warfare capabilities, including radar jamming and decoy systems, to protect warplanes from enemy detection and attacks.
