Rotron Rotary Engines



Customers talk about innovation in our engines, but what's underestimated is the innovation in our processes and operations.

Our commitment to researching new processes and manufacturing techniques has enabled enhanced engine designs. The demands for short lead times and unmatched quality are everyday challenges at Rotron. The ability to manufacture complex components both in-house and via carefully selected supplier is paramount. Our policy of continual investment in the most sophisticated and efficient CNC machines and CAE capability enhances existing capabilities and adds new in-house processes, allowing us to meet, and exceed, our customer's requirements.

Rotron's CAD/CAE Design Capabilities

CAD/CAE Design

Rotron has a highly competent and professional engineering capability with considerable experience of rotary and propulsion system design. Armed with the latest generation of computer aided design (CAD) and engineering (CAE) software, our engineering team is able to undertake clean sheet designs and optimise them quickly and efficiently. This includes a solid modelling, simulation analysis and systems modelling capability. Project teams lead by Principal and Senior Engineers ensure that our innovative designs meet our customer's exacting requirements through regular client liaison and project reviews. All manufacturing drawings are produced according to BS:8888 standards.

Analysis & Simulation

Rotron assess and evaluate every engine component that we produce to exacting standards. Our analysis and simulation processes are fully integrated into our engineering, manufacture and inspection operations using proprietary software in conjunction with additional tools we have developed in house. High specification simulation software provide the means for our engineers to carry out powerful finite element analysis (FEA). The same unique processes used throughout the engineering of our ‘off-the-shelf' engines are also applied in the design, analysis and validation of bespoke engines.

Rotron's CNC Milling Capabilities


New components and systems are developed and proved in research and development and the 3D CAD files generated during this process are available for use directly by engineering in the detailed engineering design process. Assembly modelling enables checks for fit and function to be made early in the development process, thereby avoiding the need for costly downstream remedies. The 3D master model data is used in the production of prototype parts and of tools and finished components, with a two-way flow of information ensuring that everyone is aware of the current status, while the same data is also used for Rotron's MRP system and to produce assembly instructions for the factory-floor and illustrations for operator manuals.

Engine Assembly

Highly skilled technicians hand build every engine with full build/rebuild tracking records and certificates of conformity being stored on a central database allowing full and easy traceability for serial numbers and build configurations. This data is also recorded in the engine's passport which accompanies the engine when shipped. Build integrity is checked with test procedures conducted in a dedicated test area by a separate team of technicians. Should a customer's application demand unique assembly procedures, separate specialist areas can be created on a temporary or permanent basis.

Quality Control

Rotron's quality system is constantly refined to meet the ever-increasing expectations of our customers. Quality is delivered through the close monitoring of all processes in line with AS:9001 procedures. From receiving raw materials to supplying finished assemblies and components, every step is recorded offering our customers the confidence of knowing that they are receiving consistent and repeatable levels of quality. This continual use of standard operating procedures ensures that staff at all levels understand what is expected of them, and appreciate the importance of customer satisfaction. Quality and procedural information is routinely analysed and used as measurement for any resulting improvement actions.
