Meet the Challenges in Designing Aerospace Transmissions with Romax Technology

Transmissions in aerospace applications need to be designed to withstand severe operating conditions along with requirements to achieve low weight. In most cases the transmission is also critical in terms of safety, especially in helicopters where the gearboxes are relied upon to keep them in the air.

Our clients depend on us to uphold strict confidentiality with regard to their product development, and our discretion and sensitivity to this need is one of the reasons that clients choose to work with us time and again.

Romax capabilities to create, analyse and optimise both concept layouts and detailed designs provides support to engineers to assess a large number of different options and load scenarios at an early stage. We can provide expertise for bearing selection and gear design including complex planetary arrangements, considering the influence of all system deflections.

The need to achieve low weight targets in most aerospace transmissions normally results in the use of complex light-weight structural components and housings within the design. These need to be assessed in terms of stress and deflection under the duty cycle along with the effect on planetary load sharing, gear mesh misalignment and bearing life.

The design and analysis methods developed by Romax can be utilised to consider the whole gearbox system and provide optimum solutions to ensure durability and reduce noise and vibration. The optimisation of gear micro-geometry to reduce transmission error is one example of the work that Romax can undertake within a consultancy project.
