Services
New Aircraft Development
We provide comprehensive design and analysis services for new aircraft programs, from concept evaluation through certification. Our expertise covers urban air mobility concepts, rotorcraft, business jets, and commercial airliners. We support clients with regulatory compliance (EASA, FAA, military) and offer flexible business models including on-site support and fixed-price packages. Our team applies technical excellence to develop disruptive aerospace technologies.
Computational Fluid Dynamics
Our CFD capabilities optimize fluid dynamics performance across aerospace and marine applications. We use industry-standard tools like ANSYS Fluent to model complex 3D problems, supporting design validation and certification. Services include aerodynamic analysis for aircraft modifications, hull performance predictions for marine vessels, and dynamic system modeling for multi-body environments. Our in-house HPC resources ensure secure, efficient processing.
Aircraft Modification
We deliver end-to-end aircraft modification programs including passenger-to-freighter conversions and structural changes. As an EASA Part 21J Design Organisation, we handle reverse engineering, loads analysis, and certification. Our services cover component integration, aerodynamic shape changes, and regulatory compliance, with experience in camera mounts, cargo doors, and store installations for military and civil platforms.
Landing Gear Systems
We offer independent landing gear design and integration services for fixed and rotary-wing platforms. Our capabilities include kinematic studies, shimmy analysis, hydraulic system design, and compliance with EASA/FAA standards. We support airframers and manufacturers with complete system engineering from concept through production, including associated systems like braking, steering, and door mechanisms.
Submarine Control Systems
We develop safety-critical submarine autopilot and hover systems that enhance control performance while reducing crew workload. Our solutions incorporate advanced control algorithms and safety-critical software for both legacy and modern submarines. We have delivered systems for Trafalgar Class, U212A, and Jangbogo III platforms, with expertise in at-sea optimization and integration of new technologies.
