Engineering That Flies
From first sketch to flight-ready hardware
M4 delivers practical mechanical designs backed by rigorous structural, thermal, and aeroelastic analysis. Our engineers work side-by-side with customers from concept through certification, ensuring every design is structurally sound, manufacturable, and cost-effective.
Core Capabilities
Mechanical Design
Production-ready models for airframes, spacecraft, propulsion systems, and ground support equipment. We're CAD-agnostic, with experience in NX, CATIA, SOLIDWORKS, and more.
- Airframe & structural design
- Mechanisms & deployables
- GD&T and tolerance stack-ups
- Design-for-manufacturing
Structural Analysis
Comprehensive structural evaluation using classical hand methods and advanced FEA, from preliminary sizing through certification.
- Linear & nonlinear FEA
- Impact & explicit dynamics
- Damage tolerance & fracture
- Bolted & bonded joint analysis
- Certification substantiation
Aero, CFD & Thermal
Coupled aeroelastic and thermal analyses for flight vehicles in extreme environments, integrating CFD, structural, and thermal models.
- Flutter & divergence analysis
- Computational fluid dynamics
- Coupled thermo-structural FEA
- Loads & dynamics
Full-Vehicle Structural Modeling
M4's Structures Studio enables complete aircraft structural analysis - from initial concept models to detailed certification-level FEMs. Our engineers use purpose-built tools to rapidly generate, modify, and analyze full-vehicle finite element models, cutting weeks off traditional workflows while maintaining the fidelity required for flight certification.
