Aerospace systems leave no room for approximation.

They require absolute reliability, controlled performance and engineering decisions that can be trusted over time. At Involute Transmissions, we support aerospace programs by engineering power transmission solutions designed to operate under extreme constraints, strict certification environments and long-life requirements.

Aerospace constraints

Engineering under extreme constraints

Aerospace systems operate in environments where failure is not an option.

From tight tolerance limits and high load conditions to long operational lifetimes and safety-critical functions, every technical choice must be justified, verified and validated.

Our role is to work alongside your engineering teams to transform these constraints into reliable and efficient power transmission architectures, ready for qualification and industrial deployment.

Aircraft engines & power transmission systems

Aero-engines gearboxes are among the most demanding mechanical systems in the aerospace industry.

They require extreme reliability, controlled efficiency and a perfect balance between weight, performance and durability.
That’s why, we are not just suppliers — we act as engineering partners.

Our teams work together with yours to study, design and optimize power transmission pathways adapted to your specific architectures and operating conditions.

Our expertise supports a wide range of critical aerospace systems, including:

01

Engine Gearboxes

Aerospace engine gearboxes operate under extreme conditions, combining high rotational speeds and elevated temperatures. Their design requires careful control of dynamic behavior, load distribution and scuffing resistance to ensure long-term reliability and performance.

02

eAviation solutions

The aerospace industry is undergoing major changes to reduce CO₂ emissions. We support this transition by designing gearboxes coupled with electric motors for a wide range of applications, including propulsion systems, landing gears and flight control mechanisms.

03

Bespoke actuators

Modern aircraft rely on hundreds of actuators performing critical functions. We design bespoke actuator solutions tailored to specific applications, addressing unique performance, integration and reliability requirements.
