Who We Are

A specialist airframe engineering consultancy built around engineers who have led the work at the highest level — not supported it.

We exist to be the airframe engineering team that programmes turn to when the technical stakes are highest — covering every discipline, every phase, from first concept through to in-service life.

Why DCE Exists

Airframe engineering expertise of genuine depth — across loads, aeroelasticity, structural analysis, dynamics, and certification, from concept through to in-service — is not easy to find. It is even harder to find assembled in one place, at the level that demanding programmes require. DCE Dynamics was built to be exactly that: a team of airframe specialists who cover the full technical range, not a narrow slice of it, and who have done so at chief and principal level on real, high-stakes programmes.

We understand the physics before we run the models. The analysis is a means to an end — that end is a clear, defensible answer to a real engineering question. We never deliver a result we cannot explain, and we never settle for the minimum that a customer will accept. Our reputation is built on what we actually produce, not on what we promise.

The Team Behind the Work

Prof. Dr. H. Yılmaz Kaptan

Chief Executive Officer

Yılmaz has spent his career building and leading complex technical and operational organisations at the highest level. As Dean of Engineering at multiple Turkish universities — including Hacettepe, Zonguldak BEÜ, and İstanbul Altınbaş University — and as Vice Rector at Atılım University, he has held executive responsibility for institutions with hundreds of academic staff, large research programmes, and significant operational infrastructure including Center of Excellence.

Among the most demanding of those responsibilities was managing a university-operated flight academy — encompassing flight and ground operations, airworthiness compliance, maintenance, and crew training across the full scope of a regulated aviation organisation.

He currently directs the Ekin Pre-Incubation Center at Başkent University, supporting early-stage technology ventures from research to commercial readiness. At DCE, Yılmaz leads the organisation, its partnerships, and its institutional strategy — ensuring that the firm's engineering capabilities translate into programmes and relationships built to last.

Dr. Deniz Erdayi

Chief Engineer

With over two decades at chief and principal engineer level, Deniz's career spans the full technical range — loads, aeroelasticity, structural analysis, dynamics, airframe model integration, testing and V&V, certification, and simulation automation — across civil certification, novel eVTOL, and some of Europe's most demanding military programmes.

From the earliest years of Turkey's modern aerospace industry, Deniz was part of the teams that built it — developing engineering teams, defining analysis processes, and contributing to novel aircraft that had no legacy data or established regulatory frameworks. He has mentored tens of engineers now holding senior positions across the industry.

Beyond individual programmes, he has served on technical steering committees and CEO advisory boards. He holds a Ph.D. in Computational Mechanics with research in fluid-structure interaction from METU.

The Team & Partners

In-House

The Team

Principal · Senior · Mid-level Engineers

DCE's in-house team covers every airframe discipline — loads, aeroelasticity, structural analysis, dynamics, and certification — at principal and senior level. All engineers work directly on programme deliverables. There are no layers between the client and the people doing the work.

Extended Capability

Partners

Specialist Network

For programmes requiring broader reach, DCE works with a carefully selected network of specialist organisations: a system-level and overall certification consultancy with FAA DER-qualified signatories; a structural testing laboratory for full-scale and component test campaigns; a structural repair and modification specialist with approved design organisation credentials; and a CAD, detailed design, and FEM production team for high-volume modelling and draughting work.
