Shaping the Future of Engineering & Manufacturing

Aerospace & Defense

Aerospace and defense engineering services operate within the most demanding technical, regulatory, and quality environments in engineering — where structural analysis must comply with CS-25 airworthiness codes, software must meet DO-178C Design Assurance Level A requirements, manufacturing processes must achieve NADCAP special process approval, and every design decision is traceable through an AS9100 Rev D quality management system satisfying EASA and FAA audit requirements. EMUG delivers aerospace engineering services for commercial aircraft OEMs, defense system integrators, helicopter manufacturers, space organizations, and MRO operators — covering airframe design and structural engineering using NX, CATIA V5, Creo, and 3DEXPERIENCE; aerospace CAE analysis using MSC Nastran, Abaqus, and ANSYS for static strength, fatigue, damage tolerance, and thermal programs; avionics software to DO-178C DAL A through D and DO-254 hardware design assurance; aerospace manufacturing engineering for composite tooling and assembly fixtures; MRO engineering including structural repair scheme design; EASA and FAA certification for type certificate and STC programs; SAP PLM and Teamcenter configuration management; and AS9100 Rev D quality engineering including NADCAP audit preparation and first article inspection to AS9102 Rev B.

Structural Design Leads, Chief Engineers, Head of Airworthiness, DO-178C Program Managers, and AS9100 Quality Directors at aerospace OEMs, defense primes, and Tier 1 suppliers engage EMUG when programs need specialist expertise combining aerospace domain knowledge with regulatory certification experience. Common scenarios include new type certificate programs requiring additional structural analysis and compliance documentation capacity, defense modification programs requiring ITAR-compliant engineering delivery, MRO operators requiring repair scheme design for out-of-limits structural damage, and AS9100 certification programs requiring pre-audit gap assessment and NADCAP special process audit preparation. EMUG deploys engineers on-site at aerospace facilities in Hamburg, Toulouse, Bristol, Seattle, Bangalore, and Abu Dhabi — or from secure delivery centers in Hyderabad, Germany, and Dubai with ITAR-compliant data handling.

All aerospace and defense programs at EMUG are structured through the EMUG ASCEND Framework — a six-phase methodology built for airworthiness-regulated programs. ASCEND stands for: Assess airworthiness requirements and certification scope, Scope engineering team and tool access, Configure design and analysis workflows, Execute structural and avionics programs, Navigate regulatory certification with EASA and FAA, and Deliver with full airworthiness documentation. The framework ensures every deliverable is documented, referenced, and traceable to the specific airworthiness requirement it demonstrates — not just technically correct but formatted as evidence that satisfies EASA, FAA, and AS9100 audit standards.
