COTS solution helps aerospace engineers rapidly optimise missile fin actuation system

03 October, 2023

COTS strategy advantages

Considering the stakes of missile fin actuation, a bespoke motion control approach is an option. However, time is the major constraint in design from scratch, where tooling development alone might take more than a year. Instead, a customisable off-the-shelf (COTS) solution is a practical strategy that combines a tailored design with fast delivery.

An international defence manufacturer engaged Portescap to provide a missile fin control actuation system based on this approach. Portescap’s ability to customise a COTS solution to facilitate a quick prototype, combined with experience in aerospace and defence projects, were key drivers in selecting the solution partner.

The 30ECT brushless DC motor and an M-Sense encoder were integrated into the design to maintain the small envelope and increase power output. The robust motor design met the environmental demands of the application, and careful material selection allowed the motor components to extend the 20-year storage life requirement.

Flexible engineering options

Portescap’s engineering team can also offer customisation, such as different coils to match speed and voltage requirements, as well as various shaft lengths and connectors. Along with a choice of gearbox, encoder and feedback control options, engineers can provide mechanical design integration, such as housings and flanges, to suit.

Missile fin actuation is a highly specialised pursuit, but by engaging in a COTS approach, aerospace and defence engineering teams can quickly achieve a high-performance, cost-effective, motion solution
